Flying in a Heat Wave: Safe? Legal?

I explore the logic behind performance charts and what the FAA told me about flying in hot weather.

Upcoming Weather
Next week’s weather. It’s going to be hot.

I have a Part 135 check ride coming up on Tuesday. Per the National Weather Service — my primary source of weather information — the forecast high in Wenatchee for that day is 112°F.

If you live in any country other than the metric-unfriendly US, that’s 44.4°C.

IGE Hover Chart
The IGE Hover Chart for an R44 Raven II does not chart any performance data for temperatures above 40°C.

The In Ground Effect (IGE) Hover charts for a Robinson R44 Raven II, which is what I fly, end at 40°C. That is, they do not provide any performance data for 44.4°C.

Now I learned to fly in Arizona and on a typical summer afternoon, 112°F was not uncommon. We flew in all kinds of heat. Hell, I remember landing at Bullhead City one day and reading 123°F on my outside air temperature (OAT) gauge. (And that was in a helicopter without air conditioning.) If the flight school I attended — which is still in business — didn’t fly when it was above 104°F (40°C), they wouldn’t be able to fly half the day about a third of the year. No one questioned whether it was safe or legal. We just did it.

Time went by. Someone suggested to me that flying when the temperature was above 40°C was not only unsafe but illegal. “You’re a test pilot when you do that,” more than a few people have told me. “Your insurance wouldn’t cover you in a crash,” another said, “because you’re operating outside of published data.”

Curious to see what other pilots thought about this, I put a poll on Twitter and gave the Pilots of Twitter 24 hours to respond. I also asked for comments. A lively discussion got going in the comments. It was also pointed out that I could have added “Unsafe but legal” as one of the options with the shared opinion that “the FAA gives you enough rope to hang yourself with.”

I do recall airplanes being grounded at Phoenix Sky Harbor airport one day when temperatures were “too hot” for some of the airliners, although it wasn’t clear from articles I read about how the limit was established.

Well, in an effort to head off a “gotcha” by my FAA examiner, I emailed him this morning to warn him of the heat:

A quick heads up.

We’re expecting high temperatures of 112°F on Tuesday. If you are of the school of thought that says we can’t fly when temperatures exceed 104°F because that’s the highest temperature on performance charts, we should probably plan to fly very early, before the temperature tops out. …

If you’re not of that school of thought — I learned to fly in Arizona so I’m not — we should be fine. The helicopter does have air conditioning, although I’ve never tested it in 112°F weather.

Please let me know what time you plan to arrive.

He replied, in part:

I am unaware of a temperature limitation that restricts operations of the R-44. We can complete the ground during the afternoon of the 28th so we can fly on the morning of the 29th to minimize the effects of the heat. …

So that’s telling me that it’s legal. (But he’s not taking any chances or doesn’t want to test my air conditioning.)

Never Exceed Speed
Here’s a limitations chart: Never Exceed Speed. If I extrapolated, I think operations at lower elevations would be fine, but I certainly wouldn’t exceed about 85 knots 44°C at 8000 feet. (Heck, the helicopter would be vibrating like crazy at that speed and elevation anyway.)

Is it safe? Well, as this “test pilot” could tell you, if you extrapolate the data in the charts, keeping in mind the aircraft’s gross weight and the altitude you would be operating at, it can be. Keep the aircraft light, don’t plan any high altitude landings, and keep your speed down.

Chances are, the helicopter will continue to operate in heat that you won’t want to be flying in anyway.

Why Helicopters Don’t Normally Take Off Vertically

Just because you can do something, doesn’t mean you should do it.

Every once in a while someone watching one of my YouTube videos or searching for answers on the web that bring them to this blog ask why helicopters don’t take off straight up. I guess these folks know that it’s possible and they’ve seen it often enough in the movies to think that it’s normal or at least okay. It’s neither.

I actually explain why in my much longer post about the Deadman’s Curve. But I’ll try to keep it simpler here.

The Basics

Let me start off by saying that helicopters can glide. Yes, if the engine fails, the pilot still has control over the helicopter and can fly it, using autorotation, to the ground. If conditions are right and the landing zone is appropriate and the pilot’s skills are sufficient, the pilot and passengers should be able to walk away and the helicopter might even be able to fly again.

Notice that I mentioned three ifs:

  • if the conditions are right
  • if the landing zone is appropriate
  • if the pilot’s skills are sufficient

Height-Velocity Diagram for R44 HelicopterIt’s that first if that the pilot usually has complete control over: the conditions of flight. That’s where the Height-Velocity Diagram comes into play. This diagram, which is part of the Pilot Operating Handbook (POH) that pilots are required to know inside and out (and even carry on board, as if we could consult it while flying), shows the flight profiles in which an autorotation is most likely to be completed successfully. By “flight profiles,” I’m referring to a combination of airspeed and altitude.

To meet the requirements of that first if — in other words, to fly the safest flight profile in the unlikely event of an engine failure — the pilot needs to stay out of the shaded area of the Height-Velocity Diagram. A recommended takeoff profile is shown on this chart by a dashed line that starts at 0 knots and less than 10 feet off the ground, accelerates through 45 knots while climbing less than 15 feet, and then climbs out at a speed greater than 50 knots.

Make a mental picture of that. If you’re not going to climb above 10 feet until you get to at least 30 or 40 knots, are you going to be flying straight up? No. You’re going to be taking off a lot like an airplane might, with a bunch of forward movement before you start climbing.

This is why a “normal takeoff” for a helicopter climbs out after gaining airspeed — instead of climbing straight up. It’s for safety reasons.

(This is only part of the reason why we don’t land straight down, but I’ll save that for another blog post if I get requests for it.)

FAA Guidance

The FAA has a wealth of free information about flying, including “handbooks” that explain exactly how to fly. I’ve linked to the Helicopter Flying Handbook many times; if you don’t have a copy of this excellent guide and are interested in flying helicopters, download it in PDF format here.

Here’s what it says about performing a normal takeoff from a hover (position 1 in the image that follows) on Page 9-12:

Start the helicopter moving by smoothly and slowly easing the cyclic forward (position 2). As the helicopter starts to move forward, increase the collective, as necessary, to prevent the helicopter from sinking and adjust the throttle to maintain rpm. The increase in power requires an increase in the proper antitorque pedal to maintain heading. Maintain a straight takeoff path throughout the takeoff.

While accelerating through effective translational lift (position 3), the helicopter begins to climb, and the nose tends to rise due to increased lift. At this point, adjust the collective to obtain normal climb power and apply enough forward cyclic to overcome the tendency of the nose to rise. At position 4, hold an attitude that allows a smooth acceleration toward climbing airspeed and a commensurate gain in altitude so that the takeoff profile does not take the helicopter through any of the cross-hatched or shaded areas of the height/velocity diagram. As airspeed increases (position 5), place the aircraft in trim and allow a crab to take place to maintain ground track and a more favorable climb configuration. As the helicopter continues to climb and accelerate to best rate-of-climb, apply aft cyclic pressure to raise the nose smoothly to the normal climb attitude.

Normal Takeoff
This is an exaggerated view. In reality, each position would be a lot farther apart horizontally.

In the above text, in an R44, effective translational lift (ETL) occurs between 15 and 25 knots, normal climb power is about 45 knots, and then climb out power (best rate of climb) is 60 knots. So you basically stay within 10 feet of the ground until you’re at 45 knots, then accelerate while climbing to 60 knots, and then climb out at 60. These numbers may be different for other aircraft but are likely similar.

Of course, one of the benefits of helicopters in many operational situations is that it can fly straight up. For example, I can take off from a confined space — perhaps a forest clearing — by being able to climb up above obstacles (the trees around me) before picking up airspeed and flying away. Is this safe? Well, there isn’t any signifiant danger unless the engine quits. And although the chances of the engine quitting are very slim, it is possible.

Years ago, while doing a rides event at the local airport with some fellow pilots who were working with me for cherry season, I noticed that one of the pilots was departing our landing zone by climbing straight up for 20 or 30 or even 50 feet before gaining airspeed. He was putting the aircraft right in the shaded area of the Height-Velocity Diagram. In other words, he was adding risk to his flight by basically ignoring the recommended takeoff profile.

With passengers on board. At a crowded event.

I’ve got a pretty good imagination and was immediately able to “see” what could happen if his engine quit. The helicopter would drop down with its blades still spinning. Everyone on board would likely be killed or seriously injured. And when all those spinning parts hit the ground and started flinging off in every direction, they’d likely kill or injure dozens of onlookers.

What were the chances of his engine quitting? About as close to zero as you can get without being zero. But that isn’t zero. It could happen.

After seeing him do this at least four times and realizing he wasn’t going to stop, I got on the radio and told him to stop. He asked me why. Knowing that I was talking on a frequency that could be heard by his passengers, my passengers, any other aircraft flying around the area, and anyone monitoring on the ground, I kept it simple: “Just because you can do something doesn’t mean you should.” I let him think a bit about why he shouldn’t and he stopped. (If he didn’t, I would have kicked him out of the event.)

Over the following month or so, I got to know this pilot better and I didn’t like what I saw. I don’t need to go into details here, but I feel that he’s the kind of pilot who will likely get himself killed doing something dumb in a helicopter. I’m just glad I took steps to make sure it didn’t happen on my watch.

Question Answered?

If this doesn’t answer the question about why helicopters don’t take off vertically, I don’t know what could. Please don’t hesitate to share your questions, comments, and stories in the comments for this post. Thanks!

Helicopter Minimum Altitudes

I’m working on a much longer blog post, with photos, about my recently completed autumn vacation, but I thought I’d put this shorter post out because it’s quick and on my mind.

It started with someone on Twitter sharing a video from inside the cockpit of a helicopter flying low and fast over a forest road. There were no cars on the road and no poles or wires. It was an exciting little flight that reminded me of the kind of canyon flying I used to do in some very familiar, remote areas of Arizona. See for yourself.

Helicopter video screenshot.
Here’s a screenshot from the video in question.

What followed was a bunch of comments, including some from a few people too lazy to look up the regulations who claimed that flying like that was illegal. When I pointed out that it was not illegal in the US, a particularly lazy, uninformed idiot quoted my tweet with a portion of the FARs in an attempt to prove me wrong. He didn’t. All he proved is that like so many people these days, he’s only capable of reading until he gets confirmation of what he wants the truth to be. The rest doesn’t matter.

Here’s the entire FAA regulation covering minimum flight altitudes in the US:

§91.119   Minimum safe altitudes: General.

Except when necessary for takeoff or landing, no person may operate an aircraft below the following altitudes:

(a) Anywhere. An altitude allowing, if a power unit fails, an emergency landing without undue hazard to persons or property on the surface.

(b) Over congested areas. Over any congested area of a city, town, or settlement, or over any open air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft.

(c) Over other than congested areas. An altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.

(d) Helicopters, powered parachutes, and weight-shift-control aircraft. If the operation is conducted without hazard to persons or property on the surface—

(1) A helicopter may be operated at less than the minimums prescribed in paragraph (b) or (c) of this section, provided each person operating the helicopter complies with any routes or altitudes specifically prescribed for helicopters by the FAA; and

(2) A powered parachute or weight-shift-control aircraft may be operated at less than the minimums prescribed in paragraph (c) of this section.

[Doc. No. 18334, 54 FR 34294, Aug. 18, 1989, as amended by Amdt. 91-311, 75 FR 5223, Feb. 1, 2010]

Did you read paragraph (d) and paragraph (1) right beneath it? I did, but the know-nothing twit pretending to be an expert on Twitter didn’t. It basically says that the paragraphs he quoted (paragraphs (b) and (c) above) don’t apply to helicopters.

I distinctly remember this FAR coming up during my primary training back in the late 1990s. It basically gives helicopter pilots permission to fly at any altitude they need or want to, given that “if a power unit fails, an emergency landing without undue hazard to persons or property on the surface.”

Take a look at the video. It looks to me as if the pilot is 50-100 feet off the ground. He’s moving at a good clip — at least 60 knots. (I tried to read the airspeed indicator but couldn’t.) With that altitude and airspeed combination, he’s not operating in the shaded area of the height/velocity diagram (or “deadman’s curve“). That means that a safe emergency landing is possible. And with nice smooth pavement beneath him, there’s plenty of suitable space for a landing if it was necessary. So it’s not in violation of paragraph (a) either.

Lots of people don’t get this. They assume the altitude rules apply equally to all aircraft. But they don’t. This makes it pretty clear. Trouble is, there are too many self-important assholes out there — especially on Twitter — who share inaccurate or incomplete information as fact — and too many lazy people willing to believe them without doing their own homework.

If you want to read more about this topic, here’s an old, long, rambling post I wrote about an experience related to this years ago.

Oh, and by the way, this post is about whether the flight is legal in the US. I won’t make any comments about whether it’s safe or whether the pilot is using good judgement. That’s a whole different topic.

A Word about Life after Stress

That whole thing about a weight being lifted off your shoulders? It’s true.

This past week, I’ve been stressed out a lot more than I occasionally get. It had gotten to the point where I felt an overall malaise that I couldn’t shake, accompanied by an overwhelming desire to give up on all the things I do that contribute to the stress that was making me feel so crappy.

And that’s never a good thing.

The Check Ride Stress

Quick Note:
I know that in the grand scheme of things — comparing my sources of stress to the sources other far less fortunate people face every day — I shouldn’t complain. And I’m not. I’ve been in far more stressful situations. The point of this post is not to complain or to gather pity. It’s to share an observation.

The main source of that stress was an upcoming FAA check ride scheduled for Thursday (yesterday). It was my first check ride in my new old helicopter, Mr. Bleu. I take a check ride for my Part 135 certificate every year, so it had been a full year since my previous one. I won’t hide the fact that the Spokane FSDO, which oversees my Part 135 certificate, has been getting under my skin with a series of what I consider to be unreasonable requirements. I’d been pushing back, which is something I’d never had to do with the more reasonable FSDOs and inspectors I’d worked with in the past. This was their big chance to “teach me a lesson.” At least’s that’s what was in the back of my mind as I prepped for the check ride.

But check rides are always stressful to me. You see, I never became a certified flight instructor (CFI) and I never spent 500 to 1000 hours sitting next to new students, teaching them about all the weird aerodynamic issues inherent in a rotary wing aircraft and doing dozens of autorotations every day. I have always lived in a place with amazing weather, operating primarily out of Class G and Class E airspace, so I have trouble remembering silly little (but important) things like weather minimums for the various classes of airspace. I know how to fly and I’ve been called a good stick. But that doesn’t mean I can necessarily meet the requirements of a Part 135 check ride, especially if the examiner is tough or wants to fail me.

Add to that that although I usually prep by flying with someone who works full-time or nearly full-time as a flight instructor, no one like that was available to me. My check ride was scheduled for Thursday but the CFI I’d hoped to fly with beforehand was gone until Friday. So I flew with my friend Woody, who has tens of thousands of hours flying Airbus airliners and a bunch of time flying mostly Schweizer helicopters. He’s a CFI and he’s taken more check rides over the years than there are long, hot rainless days in Arizona every year, but he approaches flying as a pilot instead of as a CFI. While that should be a good thing, I wasn’t convinced that it was a good thing for someone prepping for a check ride. (More on that in a sidebar.)

The stakes were relatively high. I needed to pass the check ride to continue doing charter and air taxi flights. Those account for about 10% of my flying revenue, which isn’t really that much. But a Part 135 certificate means I can say “yes” to just about any flight request, including something as simple as a tour that goes more than 25 miles from a starting point. It sucks when you have to turn down work because you lack the piece of paper that makes it legal. If I failed the check ride, I’d have to redo it. Since I was already in my grace month due to FAA scheduling limitations, that meant I could lose that piece of paper staring August 1. And I already have a flight booked for August 3. Redoing it meant more stress, too.

And did I mention the wind? Winds were forecasted to gust to 22 miles per hour on the date of my check ride. The check pilot was coming from Seattle and there was no chance that he’d reschedule after a 3-1/2 hour ride (each way). (I’d offered to meet him in Ellensburg to save him 90 minutes of that drive, but the wind was forecasted to gust to 37 there, so he agreed to come to Wenatchee.)

So although this was the 15th Part 135 check ride in my near 20 years as a pilot, it was stressing me out.

My R44 Helicopter in the Morning
My new old helicopter, Mr Bleu, parked in its landing zone.

On “making it work”

On my check ride, I was asked to land in a confined space on a hillside. It was a relatively big area — I’ve certainly landed in a lot tighter spaces — and there were no real obstacles, although there were some open range cattle, fencing, and a water tank nearby.

I misjudged the wind. I thought it was light and inconsequential and set up my approach to give me a the best angle of approach. As I came near the landing spot, however, I saw trees blowing and felt the wind buffeting me. Left pedal kept things under control without getting too sloppy.

Still, I decided to go around and approach from a different angle. As I told the examiner as I started going around, “If the helicopter is light, performance is not an issue, and the wind isn’t too strong, I could make this work. But making a bad approach work is probably not a good idea on a check ride.” He agreed.

And that’s the difference between flying as a pilot and flying as a CFI. A pilot flies depending on her skills, the conditions, and her intimate knowledge of the aircraft. A CFI flies depending on the best scenario learned in training. We all know it’s best to land with a headwind and that’s what the CFI will always try to do. But an experienced pilot also knows that you don’t have to fly into the wind if other conditionals make a safe operation possible. In this instance, there wasn’t that much wind and we were light. I knew I could land safely with that right quartering tailwind; I’d done similar landings before. But I also knew that the FAA was more interested in a textbook approach. My going around showed good decision-making skills and the second attempt was a lot smoother with a lot less dancing on the pedals.

The stress affected my ability to sleep. On Wednesday night, I was up for four hours in the middle of the night. Wide awake enough to read my helicopter’s Pilot Operating Handbook (POH) and Federal Aviation Regulations (FARs) in bed (on my iPad) without them putting me to sleep. I fell back to sleep at around 3:30 AM and was up again at 5:30. So on Thursday morning, I was facing a check ride with a total of about 5 hours of sleep. Not ideal. I was a basket case by the time I got to Wenatchee Airport with my helicopter to wait for the examiner.

Fortunately, it had a happy ending. I took the check ride starting at about 10:45 AM and did surprisingly well on the oral part, which usually makes me seem like an idiot. As for the flying part, I flew fine but could have made better in-flight decisions at least once. Still, it was good enough for me to pass. So by 12:30 PM Thursday, that source of stress was gone.

The Cherry Season Stress

Another source of stress this week was cherry season. We’d gotten over the hump and it hadn’t rained in a month. (We get paid for standing by, so it isn’t as if we didn’t make any money. We did fine.) But the season was winding down and there was no rain in sight and I had to decide whether to extend the contracts for any of my crew. This came down to a basic math and probability problem: How many acres were left to cover and what were the chances of it raining on all of those acres at once?

Early in the week, I didn’t have the information I needed to make a decision. That was the source of the stress: needing to make an important decision I couldn’t make because I didn’t have the information I needed to make it.

Once my crew left, I couldn’t get them back, so I had to decide at least a few days before they planned to leave. I knew I’d only need to keep one of them around if I needed any of them and I knew which one of them it would be. And I knew he wanted to stay, although his partners back in Arizona wanted him back with the helicopter. The trouble is, if I asked him to stay, I’d have to pay him more standby money. That money was coming out of my pocket and it wasn’t chump change. So the stressful part of all of this was figuring out whether I should ask him to stay before he made unchangeable plans to leave.

Cherry season is stressful.
I should mention here that cherry season is always a very stressful time for me, starting in April, a good two months before the season starts. In April, I’m trying to secure my contracts and get acreage counts so I know how many pilots I need. In May, I’m trying to lock in pilots who are freaking out because I can’t give them exact start dates. In June and July, I’m watching the weather, trying to foresee storms and flight needs, and making sure my pilots don’t wander off. In August, I’m still watching the weather and hoping that I can cover whatever acreage is left by myself. So it’s up to five months of varying levels of stress. August 11 is my last day this year and I can’t tell you how much I’m looking forward to it.

I started getting acreage estimates on Tuesday. By Wednesday, I was able to do the math part with some degree of accuracy. If I let all my guys go, on the first day they were all gone, I’d be right at the limit of the number of acres I could cover alone. If it rained everywhere, I’d be stretched thin. But too thin? And what was the chance of rain?

By Thursday, I was confident that there was no chance of rain for at least three days after the last member of my crew left. By the end of those days, it didn’t matter if it rained because the number of acres left to dry — remember, they’re picking cherries every day now — would easily be within my capability to dry alone.

So the stress from that decision was gone by Thursday, too.

The Tiny Sources of Stress

I have a few other tiny sources of everyday stress in my life.

  • Jeep air conditioner. It’s on the fritz, making a weird sound when the fan is on medium-high or high. That’ll need to get looked at.
  • Business planning. Believe it or not, I’m considering starting a new business with a partner here in Wenatchee. This is a huge decision for me and there’s some stress related to the yes/no decision of starting it at all.
  • Responsibilities. Like most folks, I have the responsibility of owning and managing a home and doing the work I do to make a living. Sometimes it’s more stressful than other times, but if I couldn’t handle that stress, which never really goes away, I should probably sell out, retire, and live in a rest home.

In all honesty, I can’t even count these as “stress,” mostly because they come and go on a daily basis. They’re part of life.

When the Stress Is Gone

What I really wanted to write about here is how I feel this morning. In one word: great!

Yesterday, after my check ride and lunch with Woody and an appointment to get my hair tended to, I rescheduled the business planning meeting I had set for 6 PM to sometime later in the weekend. On my way home from the hairdresser, I shopped at my favorite craft cocktail place and had one of their concoctions. I normally don’t drink at all during cherry season, but with absolutely no chance of rain, I didn’t think it would hurt. And I thought it might help for what I had planned next: sleep.

I was dead asleep by 7 PM. And I stayed that way until 3:30 AM. That’s 8-1/2 hours.

Now most folks probably wouldn’t be happy waking up at 3:30 in the morning. But after a solid night’s sleep, what difference does the time make? I spent some time sitting out on in the cool air on my deck, just looking out at the lights of the Wenatchee Valley. Then, as the eastern sky started to brighten, I went in and made my coffee.

That’s when I realized how good I felt and why: the stress was gone.

And with the stress gone, so was the malaise.

How could I have even considered giving up on the things I do? Running my helicopter services business? Managing over a dozen cherry drying contracts? Caring for and improving my home? Managing Airbnb properties? Making and selling jewelry? Raising chickens for eggs? Keeping bees? Gardening? Polishing gemstones?

And why wouldn’t I dive into a new business venture with a friend?

When I was stressed out earlier in the week, that feeling of malaise was making me question why I was doing any of these things, reminding me that the people whose lives revolve around a dull job and evenings spent watching television don’t get stressed out. The stress comes, in part, from facing challenges. No challenges, no stress.

But what those people don’t realize is that without self-imposed challenges, there’s no real meaning to life. They’re missing out on the amazing feeling of success that comes when facing a hurdle and jumping it.

Because isn’t that what I’m doing?

I wouldn’t have to take that check ride if I didn’t build and maintain a Part 135 helicopter business.

I wouldn’t have to make difficult staffing decisions if I didn’t take on the challenge of managing cherry drying contracts every year.

I make my stress when I take on these endeavors. The stress is usually temporary. And getting past it is what makes me tick, the reward of success is what drives me.

And I feel great today.

A Story about Questioning Authority

If something doesn’t sound right, it might not be.

Those of you who follow the aviation-related posts in this blog — and there are a lot of you — might recall how I balked last year when the FAA told me I was required to buy a radar altimeter to continue Part 135 charter operations in my VFR-only aircraft. I argued that a radar altimeter’s sole purpose was to tell a pilot how far the aircraft was from the ground and that VFR operations, by definition, meant that the pilot could see the ground. If I wanted to know how far I was from the ground, all I had to do was look out the window. I didn’t need to spend $8K to $20K for an instrument inside the cockpit to tell me how far from the ground I was.

The argument apparently had some merit because a handful of Part 135 operations like mine, who apparently have more reasonable FAA oversight, got a waiver of the requirement. To this day, they still have that waiver.

I fought long and hard on this issue and, in the end, lost. Through the efforts of someone at Helicopter Association International (HAI), I got a temporary waiver that gave me until this coming October to comply. I wound up having one installed on Mr. Bleu (my new old helicopter) because the kind folks I bought it from offered to do the labor for free. It still cost me $10K. (Unfortunately, I have to pass that cost on to my charter clients with a $25/landing fee for all Part 135 flights.)

A lot of people might think that my experience with this would convince me that it isn’t worth fighting when you think something is wrong. That’s simply not true. I will always fight for what I think is right — if it’s important to me. Yes, I pick my battles.

And that brings me to the topic of today’s blog post: two FAA findings in yesterday’s aircraft inspection.

A Tiny Bit of Backstory

When Zero-Mike-Lima was totaled, I had no helicopter. One of the requirements of a Part 135 certificate — the FAA certification that enables me to legally do air-taxi work — is that I have at least one helicopter on my certificate. When I informed my local FAA Flight Standards District Office (FSDO) that Zero-Mike-Lima was gone, they waited a week or two before kindly informing me that if I didn’t replace it soon, they’d cancel my certificate.

This is a huge deal. It took just four months for me to get my certificate in the beginning of 2005 and that was considered lightning fast. These days, it’s rare to get the process done in less than two years.

Admittedly, I don’t use my Part 135 certificate much anymore. Most of my work centers around cherry drying, with a dose of aerial photo/survey work, scenic tours within 25 miles of the starting point, and hop rides at outdoor events. For a while I was doing a lot of wine tasting tours, but I’ve dialed that down to hour-long trips that are a bit pricey for the average wine lover. Still, I want to keep my Part 135 certificate because it enables me to say yes to the odd charter flight that comes my way. When you have a small business with limited activity, being able to say yes can make a big difference in your bottom line.

So I was motivated to get a replacement. I blogged about my shopping experience here and about picking up Mr. Bleu and flying it home with a friend here. Once it was here and I had all the paperwork I needed the FAA to review, I contacted my guys at the FSDO to arrange for an inspection.

You see, it isn’t enough for me to get a helicopter. The FAA has to inspect it. There’s a laundry list of requirements for Part 135 work, as well as the general airworthiness of the aircraft itself. That’s why I was so picky about what I bought and why I wound up buying the helicopter I did. I knew it would comply with all requirements so it would be easy for me and for the FAA to get it on my certificate.

The Inspection

The FAA scheduled the inspection for May 3. I was expecting my Primary Operations Inspector (POI) and Primary Maintenance Inspector (PMI). That’s two guys. So imagine my surprise when a small car rolled into my driveway that morning and four guys got out of it.

Apparently, my inspection was part of a training exercise. Lucky me.

They all came upstairs and I handed over all of the helicopter’s paperwork to them. I pulled out my big dining room table — I normally keep it stowed against a wall — and the three maintenance related guys sat around it. I sat at the breakfast bar with my POI to talk about operations stuff. It seemed that they were combining the aircraft inspection with a base inspection and a post-crash interview. That was fine. I had nothing to hide and I was confident that the aircraft would meet their requirements.

I have to say that I did the right thing when I bought a helicopter with just one previous owner from a place with a well-managed maintenance shop. Every single document that they were looking for was in the packet I had for them. The only two things they brought to my attention is my need to register my ELT (Emergency Locator Transmitter; a piece of emergency equipment) and the possibility that I might need to update my Pilot Operating Handbook (POH) with a manual for the radar altimeter. That second finding actually came later, when they looked at the helicopter.

And that’s where we went next: to the helicopter. After I asked my PMI to take off his FAA hat and help me get my new printer up onto my loft and a chair down from my loft — a matter of handing a box up to me and taking a lightweight chair I handed down — we went back downstairs. They all climbed into their car — which, by that point, I had begun thinking of as a clown car, mostly because of so many big guys being in such a relatively small car — and I pulled my Jeep out of my garage. I led the way back down my road and around to my neighbor’s airstrip, where the helicopter was parked. (Long story there; it’ll eventually get blogged about.) We parked next to the helicopter and got out. I pulled off the cover and opened the doors. The four guys moved in.

At one point, I almost got a photo of them all poking their heads into various parts of the helicopter, but as soon as I took my phone out, one of them moved away and I skipped the shot.

I answered questions. We talked about the fire extinguisher (the Spokane FSDO seems obsessed with it — in 9 years the Scottsdale FSDO never even looked at it) and I was told that it needed to be inspected monthly by a mechanic who would put an entry in the aircraft logbook. We talked about the POH and my possible need to add a manual to the Supplements section for my radio altimeter — although no one seemed to know for sure if such a supplement existed or was actually required. We talked about the level of the main rotor gearbox fluid. We talked about how clean the helicopter was.

And we talked about safety wire.

The Safety Wire

Safety wire, in case you don’t know, is thin wire that’s used to secure nuts and other removable items. It prevents them from loosening and potentially spinning off. Look at any aircraft long enough and you’ll find these thin wires here and there, twisted tight.

The maintenance guys pointed out that there was no safety wire on the tail rotor gearbox or oil filter. This was a “finding” — that’s a word that auditors use when they find something wrong. I don’t know what FAA guys call it. Exception? Non-Compliance?

I was embarrassed. I should have caught that on preflight but didn’t. It looked fine to me. But what really surprised me was that the maintenance shop had let it go like that. I decided to rib them about it later.

I told the FAA guys that I’d fly it to the airport to have the mechanic there add the wire. They told me I needed a ferry permit. Apparently the aircraft was not airworthy without it. I said I’d get a ferry permit, imagining some form I’d fill out online. They asked if I’d ever gotten one before. I said no. They said that I’d have to fill out a form and then get a mechanic out to look at the aircraft and sign off on it.

“Since the mechanic has to come out here anyway, can’t he just add the wire while he’s here?” I asked.

“Bingo,” one of them replied.

I made a mental note to get in touch with the local airplane mechanic when the FAA left.

The Doors

At that point, we seemed to be done. But then my PMI said, “And we need to talk about the doors.”

They had sent me a document a week or two before (InFO 18002) that talked about helicopters on fire contracts, removing and installing doors in remote areas, and cargo doors (which I don’t have). It didn’t seem to apply to my operation.

Robinson helicopters have simple door attachments: two hinge pins with round cotter pins to prevent them from slipping out, combined with little hydraulic do-dads that keep the door open when you open it. Of course, there’s a latch to hold the door closed in flight or when parked. Pretty simple stuff. As a student pilot in Arizona 20 years ago, one of the first things I learned was how to remove and install the doors on the R22s I trained in. With daytime shade temperatures in triple digits six months out of the year, I think we flew more often with doors off than doors on. That was certainly the case when I bought my first helicopter in 2000.

After reading the document, I’d emailed my PMI to tell him I didn’t think it applied to my operation. He said we’d talk about it at the inspection. This was the talk.

It wasn’t good news. According to the Spokane Gang of Four, I was not permitted to remove or install the doors on my helicopter since it was used for Part 135 operations. In the judgement of someone in Washington (who really needs a hobby), removing and installing doors is a “maintenance item.” Because it’s a maintenance item, it needs to be done by a mechanic and an aircraft logbook entry must be made. In large Part 135 organizations, the Maintenance Training Program can include instructions for training a pilot to do this job while operating in a remote area when a mechanic isn’t available. But since I was a single Pilot Part 135 operator and I didn’t have a Maintenance Training Program because I (1) didn’t have a maintenance department and (2) didn’t need one, I could not be trained to do this job so I could not do it.

So yes, they were telling me that I was no longer allowed to do a simple task that I had been doing for about 20 years.

Doors off Mr. Bleu
Here’s Mr. Bleu on a photography client’s front lawn not long after my FAA inspection. The front seat photographer did still photos while the guy behind him did video. (By Chelan County’s definition, this is a heliport. Go figure.)

Now you might wonder why this mattered to me. First, understand why I might need to take one or more doors off. It’s mostly for aerial photo work — no serious photographer is interested in shooting images through a curved, possibly dusty Plexiglas window. I have worked with photographers who have chosen me because other operators refused to remove a door for them. Doors off is required and, coincidentally, I had booked a photo flight for the following Monday.

Second, if the doors could only be removed and installed by a mechanic, that meant I’d have to schedule a flight to the airport when a mechanic was present (9-5, M-F), wait while he removed the doors and made the logbook entry, do my doors-off flight, return to the airport when the mechanic was present (9-5, M-F) to have the mechanic install the doors and make another logbook entry, pay the mechanic for his time, and fly back to my off-airport landing zone.

The level of inconvenience this interpretation of some obscure rule was causing me was astounding. Consider my Monday flight, when I was scheduled to meet my client in Leavenworth — the opposite direction of the airport — at 7 AM — two hours before my mechanic gets to work. That meant I’d have to fly to the airport the day before — well, no because that was Sunday so I really needed to be there three days before, on Friday — to have the doors removed, then return to my landing zone, leave the doors off while parked for several days, fly to meet my client on Monday, and then return to the airport before returning to base. I figure 4/10 hour on the hobbs meter just to add in all the flight time for the mechanic.

And in a helicopter, time is real money.

And what happens if I pick up a tour flight after the doors have been taken off? Do I just apologize to the folks paying me nearly $600/hour for the drafty in-flight conditions? Or just say no to them, thus taking a pass on an hour’s worth of revenue, and hope the photographer doesn’t cancel, leaving me with a net loss for the doors off adventure?

According to the Spokane Gang of Four, there was no way around this for me. Not at all. No waivers or anything else.

And that’s when I got seriously pissed off.

“Breathe”

After covering the helicopter back up and watching the FAA guys drive away in their little car — and wondering how comfortable they could possibly be crammed in there for the 3-hour ride back to Spokane — I got back into my Jeep and headed into town to run some errands. On the way, I called another Part 135 operator friend and vented to him about the doors, knowing that he was in the same boat as me.

“Breathe,” he told me. And then he told me a few other things that I won’t repeat here, including how he planned to deal with it.

I relaxed a little, but I knew his solution would not work for me. I’m too fucking honest.

And that’s really what it all comes down to: honesty. The FAA makes these rules that are nearly impossible to comply with, knowing damn well that some operators just won’t follow the rules because they can’t. It’s like they’re setting a trap. And one day, when they decide they just don’t want to deal with you anymore, they spring that trap and pull your ticket.

I have to say that I never thought this way about the FAA until I moved my operation to the management of the Spokane FSDO. I’m not sure if its a timing thing — maybe the whole FAA has changed? — or it’s just a higher level of unreasonableness. I thought the goal was to ensure safety. These days, it seems as if the goal is to see how many hoops an operator will jump through — how much money they’ll throw away on useless equipment and “maintenance” — before they throw in the towel and quit flying.

Another Part 135 operator friend of mine had enough when they zapped him for doing a photo flight at a train yard — long story there — and decided to punish him by suspending his license during cherry season, which is when he made 90% of his flying income. His “you can’t fire me I quit” response was to sell his helicopter and get out of the business entirely. I suspect that’s exactly what they wanted. I’ve also come to suspect that this FSDO sees small operators as nuisances. That would surely explain the failure to give waivers for a useless piece of equipment in a VFR-only aircraft — the radar altimeter — and this new rule about removing and installing doors.

The Safety Wire, Revisited

Of course, I also had to deal with the safety wire to satisfy the FAA guys. That meant getting my mechanic out to the helicopter to do the job, taking photos of the finished work, and scanning the logbook entry. I’d send all that evidence to them as soon as possible, knowing how long it takes them to process requests. All this had to be done before my photo flight on Monday. (Oddly, I wouldn’t need to have the mechanic remove the doors then because the helicopter was not yet on my Part 135 certificate so it was still legal for me to do it, as long as I made a logbook entry. I’m still trying to wrap my head around that convoluted piece of logic.)

But I wanted to rib the maintenance shop about missing the safety wires so I shot off a text to Paul, the Director of Maintenance where I bought the helicopter:

Spokane sent FOUR inspectors today. Just a few minor problems to resolve, the most embarrassing of which is the fact that there was no safety wire on the tail rotor gearbox and oil filter. (Oops!) I’m hoping to get a mechanic out to my LZ to fix that tomorrow. There was also some question on whether I need a radio altimeter supplement in my POH on board. Do you know?

Then they told me that I’m not allowed to remove or reinstall my doors because I’m not a mechanic.

His response came moments later:

Safety wire is not required.

There was more, mostly from me, but I’d prefer not to repeat it here. A while later, when I got home, I got his brief email:

Safety wire SL-45 link.
https://robinsonheli.com/wp-content/uploads/2015/12/r44_sl45.pdf

Sure enough, Robinson Helicopter Company had issued a Safety Letter dated July 3, 2013 titled “Deleted Safety Wire.” The Background section stated:

Safety wire and safety wire provisions have been deleted from various installations and parts. Deleting safety wire reduces maintenance cost and decreases the potential for safety wire-related FOD. This letter provides guidance for installing parts with or without safety wire provisions.

You can bet I wasted no time forwarding that document to my PMI. I’m sure it got to his office in Spokane before he did. Of course, he never said a word about it. I had to email him the following week to ask if he’d gotten it and whether it was still an issue. His response was brief:

I got it thank you. It takes care of the question raised about the safety wire.

There are three lessons to learn here:

  • The FAA is not all-knowing. In their defense, how could they be? There are hundreds of makes and models of aircraft. How could they be expected to know about every maintenance procedure or service letter for every one. While it bugs me that they automatically assumed there was a problem, it felt really good to educate them.
  • An experienced mechanic knows stuff the FAA doesn’t. I had already suspected this — which is why I prefer taking my aircraft for repairs and maintenance to a shop that sees Robinson Helicopters all the time — but my safety wire experience proved it.
  • Questioning authority can save you money. In this case, I saved at least $100 — the cost of getting a mechanic out to my LZ, which is a good 40-minute drive from the airport, for a 15 minute job that actually would have had me in non-compliance with Robinson’s Safety Notice.

But this got me thinking about the doors-off issue. If Robinson said safety wire wasn’t necessary in a place where the FAA thought it was, perhaps Robinson could weigh in on the door removal issue?

But haven’t you read enough here? (I’m surprised you made it this far.) I think I’ll save the door issue for another blog post. As you’ll see, it’s not a simple matter.
