Smoke in the Cockpit!

How I learn the importance of having a fire extinguisher on board.

Saturday, February 7, 2004 was a typical Arizona winter day. Temperatures in the 60s, clear skies, light winds. Mike was working at the airport until 2 pm, when we expected a furniture delivery. The monthly airport barbeque was set up by 11:30 when I decided to take a trip down to the place I planned to do some desert barnstorming the following day.

A few weeks before, Janet and I had done some desert barnstorming in Tristan’s R44 helicopter, north of Carefree Highway, west of Lake Pleasant where some ATVers had gathered to ride on the trails. We didn’t do very well — we just did one ride for three people — but one of the people told us that there was a big motorcross scheduled for February 8. They told us that if we came back then, we’d be able to do lots of rides.

I decided to check things out the day before. Since my helicopter is a heck of a lot cheaper to fly than Tristan’s, I fired it up and headed east.

Things were really hopping when I got there. The place was full of trailers and dirt bikes and a huge red and white striped tent had been set up not far from a good landing zone. I set Three-Niner-Lima down and kept an eye out while I shut down. When the blades had stopped, I made my way to the big tent.

There was a lot of activity in the area. Dirt bikes rolled by, stirring up clouds of dust. Vendors selling all kinds of dirt bike paraphernalia had set up shop under canopies alongside the dirt road. There was even a food vendor with a smoker.

The huge tent was almost empty. Tables had been set up around the perimeter, but there wasn’t much going on at any of them. In the back was a table with two computers and a few guys staring at them. I walked back and introduced myself.

Oddly enough, one of the guys at the computers was one of the three people who’d flown with me a few weeks before. He remembered me and called over someone else who was a decision maker. She was thrilled to see me. She told me she was supposed to call me and had forgotten. She was glad I’d come. Of course I could do rides. She called over another boss person and told him. He was busy but seemed mildly interested. He said he’d announce the rides at the dinner that night. I offered three free rides for a raffle and promised to return the next day with my ground crew.

It was nearly 1 pm when I returned to Three-Niner-Lima. I’d promised Mike I’d be back by 1:30 so I could go home and await the furniture. I checked the oil, walked around to look for obvious tampering, and climbed aboard. Then I went through my all-too-familiar ritual of starting up.

I put my headset on, leaving my right ear uncovered. I pushed the mixture full rich. I turned on the master switch. I opened my door and called out “Clear!”, making sure it really was clear. Then I turned the key to start and started the engine. Flicked the Clutch, Strobe, and Alternator switches. Checked to make sure I had good oil pressure and that the starter light was out. The blade started turning. Then I turned on the avionics in the usual order: transponder, radio, GPS.

“Pop!”

The sound was new, something I’d never heard before. I distinctly remember saying “That’s odd,” to myself. “I wonder what that is?” Then I looked at the instrument panel and saw the puff of smoke on the passenger side, right beside the GPS.

Smoke.

I cut the throttle, flicked the clutch off, and pulled the mixture. The engine died. I remembered my fire emergency procedures and flicked off all switches, then turned the fuel selector to off. I opened my door and stepped outside, looking anxiously in the cabin I’d just vacated.

Fortunately, nothing was on fire. The smoke dissipated, leaving an electical fire smell behind.

I waited to be sure that nothing was on fire. Then I thought about my situation. Parked out in the desert, about 20 miles from home. Furniture due to arrive in an hour. Mike would be pissed.

But hell, my helicopter could be on fire!

But it wasn’t.

I remembered my emergency kit, which I kept under my seat. I dug it out. It has a very nice Swiss Army tool in it. With a screwdriver that I could use to open the instrument panel for a peek inside.

I was unscrewing the panel when a man rode up on his ATV. I told him my situation as I worked. He told me he was an electrician. (How could I get so lucky?) He helped me open the panel. I swung it back and we peered inside. No trace of any problem. No trace of burning, smoke, or anything else. Surprisingly, not even much dust.

Not satisfied, I decided to remove the panel covering my avionics. We had four screws out when we realized that there would be at least eight screws and we’d need a microscopic allen wrench to get the knob off my radio. That wasn’t a job to do out in the desert. So we closed it back up.

He asked me if I had a fire extinguisher. I told him I didn’t. He told me he’d get me one and took off on his ATV.

I called Mike and told him the situation. I couldn’t stand next to the helicopter while I was on the phone. The signal was bad there. I had to walk 20 feet away. I told him what had happen and what I’d done. I told him I planned to start up the ship with the circuit breakers for the avionics pulled. If that worked, I’d fly home. But I wouldn’t have any radios, so he should start making radio calls for me in about 20 minutes, warning area pilots that a helicopter without radios was on its way in.

The man on the ATV returned with a small fire extinguisher. He told me it belonged to the people serving food and made me promise to bring it back. I promised. I also promised to give him a helicopter ride the next day. I studied the instructions on the fire extinguisher and stowed it on the passenger side floor. Then I climbed back on board and he rode away. I pulled out the Pilot Operating Handbook and read the Fire procedures in the Emergency Procedures section, just to make sure I knew them very well.

I pulled the two avionics circuit breakers and the one for the avionics fan. I figured that if there was a fire in there, the last thing I needed was a fan blowing air on it. Then I went through my startup ritual (see above), skipping the part where I turn on the avionics. The blades were spinning when I realized that I was hearing a rhythmic clicking sound I don’t think I’d ever heard before. Although there was no smoke, the sound spooked me. I turned everything off again.

Now I was desperate. I wasn’t sure if the helicopter was safe to fly, but I didn’t know what to do. I called MIke again and gave him an update. He started making plans for coming to pick me up. Then I told him I’d call Paul Mansfield.

Paul Mansfield was my mechanic. He’s probably one of the best Robinson Helicopter mechanics out there. Unfortunately, due to a disagreement between me and the company he works for, I’m not allowed to bring my helicopter to him for servicing. I wasn’t very happy about this and neither was he. He told me that if I ever had a problem, I could call him. He even gave me his cell phone number.

Throughout the past three years or so, I’ve called him about four times. He’s been very helpful. I called him that day. He answered. I told my story. When I got to the part about the smoke, he said what I’d been thinking at the time: “That’s not good.” I was glad we agreed on that point.

He thought the problem might be in the strobe, which I’d turned on right before the avionics and had turned on the second time I’d started, too. The rhythmic clicking sound could correspond to the charging mechanism. He thought I might be hearing it through my headset. He suggested that I leave the strobe off and give it a try. I thanked him and hung up.

I called Mike to give him an update. By now, it was almost 1:30. I was going to be late — if I ever made it at all.

I climbed aboard again and pulled two more circuit breakers: the strobe and the intercom (what the heck; who was I going to talk to anyway?). I started it up. The clicking was gone. There was no smoke. Everything was fine.

Of course, a ton of stuff wasn’t even turned on.

I took off cautiously, my eyes straying occasionally to where I’d seen the smoke and the fire extinguisher lying on the floor beyond it. I flew low for two reasons. First, without a radio, I wouldn’t be able to announce my position to anyone. I was far less likely to encounter someone at 400 feet AGL than higher. Second, I wanted to be close to the ground in case I needed to land in a hurry. Let’s face it, the closer you are to the ground, the quicker you’ll get there.

I also decided not to take the quickest route home, which went across the mostly flat and definitely empty desert. If I had to land, I wanted to land where some people would see me and be able to help — or at least give me a ride to civilization. So I followed Carefree Highway and, when I reached it, Grand Avenue.

My Bose headset, which has excellent noise cancellation features, completely stinks when it isn’t powered up. I’d unplugged it before taking off, so it offered very little sound muffling. The helicopter was very loud and I imagined that every noise was a new one, one that could mean trouble. But there was no trouble. I flew into Wickenburg, flying only about 300 feet above the ground so I’d remain clear of any traffic in the pattern or departing the area. Then I made an approach from the south to the helipad. It was 1:50 PM when I set down.

Mike was busy fueling helicopters: a Schweitzer 300 and a Robinson R22. I wanted to look at the Schweitzer, but didn’t have time. I hopped in my Jeep and went home. The furniture guys arrived five minutes after I did. Mike arrived ten minutes later.

On Monday, my local mechanic, Ed, took apart the instrument panel and removed the avionics. The GPS had faint singe marks on it, but when we removed it from its case, its circuits were okay. He reassembled everything and we powered up the avionics stack. No popping noises, no smoke. Everything fully functioning.

I hate when that happens.

Ed thinks there might have been a loose screw or something inside the stack. It hit the GPS case and caused a little short circuit, complete with smoke, but didn’t pop the circuit breaker. Then the helicopter’s vibrations shook the screw into a place where it couldn’t be found. A place where it wouldn’t pop again.

I hope Ed is right and that there’s no more smoke in my cockpit.

Since then, I’ve flown more than 6 hours in Three-Niner-Lima — now nicknamed “Smokey” — and haven’t had any problems at all. It went to Prescott for a 100-hour inspection and Cody, the mechanic there, couldn’t find any problems either.

But I bought Three-Niner-Lima a present from the Robinson Helicopter Company: its very own fire extinguisher.

The Kofa Cafe is Gone

One of my favorite fly-in destinations changes ownership and goes down the tubes.

The Kofa Cafe is gone. And I’m very unhappy about it.

The Kofa Cafe was one of my favorite fly-in meal destinations. About 50 nautical miles southwest of Wickenburg (bearing 240° as per my GPS), it was a great place to fly for a burger, some good chicken fried steak, or an ice cream sundae. I’d land in the back, among the creosote bushes and pencil cholla, off the dirt road so I wouldn’t kick up so much dust with my rotor wash. I’d shut down and walk in. Because no windows looked out at the back, no one knew I’d arrived by helicopter. I’d have my meal, visit the ladies room, pay, and leave.

Kofa CafeI wrote about my first landing at the Kofa Cafe in an article for wickenburg-az.com’s Day Trips section. I liked the restaurant’s big servings and down-to-earth atmosphere. I liked all the junk out on the front porch and in the yard. I liked eating with the truckers. I liked taking the helicopter someplace that wasn’t on an airport but didn’t get me in trouble. Three-Niner-Lima parked in the truck parking area the first time I visited the Kofa Cafe. The Cafe is the blue building.

The Kofa Cafe was for sale for years. No one wanted to buy it. Finally, the owners just packed up everything on the porch, locked the doors, and left. That was last spring. I’d arranged a helicopter outing there with our Heli Group and I found out the day before that the place had closed down. (We wound up going to Prescott instead. Not the same.)

But a few weeks ago, Mike and I had flown over in Mike’s plane. When I looked down, I saw cars in the parking lot. Perhaps the owners had come back. Perhaps they’d opened for the season. Today, I decided to fly out and find out.

Well, the old owners didn’t come back. Instead, there’s a new owner. He was there and he’s a certifiable jerk. He spent all of his time talking loudly to another customer, telling them how he runs the place so much cheaper than the last one. He complained about my waitress putting too much whipped creme (not cream) on my sundae — “I lose $2 every time she makes one of those.” He demanded to know why he was paying for iceberg lettuce and bagged salad. He claimed his property was worth “three quarters of a million dollars” and that’s why he lived in a motorhome there.

The guy was obnoxious, the place was sad. It had been open 24 hours a day. Now it’s open 12 hours a day, only 6 days a week. Half the menu items are gone. There are only three flavors of ice cream. The pies aren’t’ even made on the premises anymore. And I won’t even go into detail about the Alzheimer’s lady they leave sitting at a table by herself so they can keep an eye on her.

The waitress was unhappy. Frankly, I would quit rather than put up with her boss’s obnoxious behavior.

Needless to say, I won’t be back unless it gets a new owner again.

The Kofa Cafe is indeed gone — don’t let anyone tell you otherwise.

Flashback: September 1, 2002

The hidden cabins of the Weaver Mountains.

Richard’s story emerged over lunch at a local restaurant. I don’t even know how it came up in the conversation.

Years ago, he and his stepfather had gone on a four-day hike in the desert, looking for lost treasure. They’d followed old mining roads and pack trails high up into the Weaver Mountains, following vague directions given to them by an old miner who had recently gone to that great mother lode in the sky. As days wore on, they found one landmark after another. On the third morning, they were searching for their last landmark, some cabins deep in a thickly treed canyon. Although they couldn’t see any sign of the cabins from a ridge overlooking miles of high desert terrain, later that day they stumbled upon them while following a spring-fed creek. By then, they were out of time and had to start on their way back home. They never went back.

Richard’s tale of a four-day hike in the desert, living off the land and finding old buildings hidden away in canyons, fascinated me. I’d done my share of exploring when I was in my teens and had some interesting tales to tell. But none could come close to his. I wanted to know more, to see the cabins with my own eyes. Perhaps I thought it was a way to recapture part of my youth, when the simple pleasure of discovery was all the reward I needed after a long hike on a hot day.

But although Richard wanted very much to find the site again, a work-related injury made a long hike or horseback ride impossible. And Richard was certain that there were no roads anywhere near the canyon, so a Jeep wouldn’t get us there. Besides, with thousands of acres of mountainous terrain and numerous canyons with spring-fed creeks, locating the site would be like finding a cactus spine in a patch of tumbleweed. After all, Richard’s initial visit had been long before the era of GPS and he wasn’t sure where the site was.

I can’t recall if it were Richard or me who suggested the helicopter as a means to find his hidden cabins. If Richard suggested it, I’d probably been thinking about it quietly already, so his suggestion seemed perfectly natural. If I suggested it, I don’t recall him being surprised, so he must have been thinking about it, too.

Three-Niner-Lima, as I call my helicopter, is a 1999 Robinson R22 Beta II. I’ve owned it since October 2000 and have done most of my flying at its controls. I learned to fly late in life, earning my private pilot helicopter rating shortly before my 39th birthday and my commercial rating a year and a half later. Three-Niner-Lima seats two, including the pilot. Although it doesn’t have much power — a fact that becomes apparent at higher elevations, especially on warm days — it’s fun and relatively inexpensive to fly.

Richard, his wife Christal, and I met again over breakfast the next day. I brought along some topographic maps. Richard pointed out where he and his stepfather had parked the car for their hike and where he thought they’d hiked. He pointed out a few canyons with springs that could be the canyon they’d visited. I saw a number of 4WD roads and pack trails on the map and pointed them out. Richard repeated with certainty that there were no roads leading into the canyon.

There was a lot of mountainous terrain to cover. When flying helicopters, mountains mean three things: high elevation, which limits available power; unusual winds, which can make landing difficult or hazardous; and uneven terrain, which makes it hard to find an emergency landing area in the unlikely event of an engine failure. With all this in mind, I suggested that we begin our search early in the morning, before the temperature rises and the winds kick up. We agreed to meet at 6:00 AM.

One thing led to another and I was unable to keep our appointment. So we put it off a few days. Thus, it was by chance that we made our flight thirty years to the day of Richard’s original hike — a fact Richard didn’t realize until much later.

The morning of our flight was clear, cool, and calm. We took off from Wickenburg, heading north, just after sunrise. Although Three-Niner-Lima was equipped with a panel-mounted GPS, I brought along my hand-held Garmin, which has mapping capabilities, and set it up to log our route. Later, I was able to overlay the route on some topographic maps, which gave us an interesting view of our flight.

We climbed over the Weaver Mountains in the early morning light. It was slightly hazy that September morning, as if the desert were trying to send its moisture up to the sky to start monsoonal rains as early as possible. But because the summer had been so dry, the desert was a parched beige color, with dusty green patches of vegetation. Up in the Weavers, however, it was obvious where springs flowed. Dozens of canyons were green with tall cottonwoods and other water-loving trees of the desert. It was under one of those canopies of trees that we’d find the hidden cabins.

We flew a relatively standard search-and-rescue pattern, weaving back and forth over one canyon after another. For safety’s sake, I needed to remain at least 500 feet up. Since we were operating in an area of rapidly changing elevations, I kept my eyes outside the cockpit, concentrating on keeping us clear of terrain. I did my best to place the best view on the left side of the cockpit, where Richard sat, scanning the ground.

After about 40 minutes of searching, we were getting discouraged. I felt bad for Richard, who had come prepared with hiking shoes, water pack, and camera, ready to relive a thirty-year-old experience. He clearly expected us to land somewhere and it had gotten to the point where he didn’t really care where. We talked about finding a landing zone near one of the more densely vegetated canyons and I saw a spot that might work. After doing a high reconnaissance, I told him I’d try an approach, but warned that if the site didn’t look smooth or level, I’d have to break it off.

I went in cautiously, my eyes on the proposed landing zone, an arm of the mountain that seemed flat and clear. I was about 100 feet from the ground when Richard called out suddenly, “There it is!” I tore my eyes from the landing zone for a quick look and saw the weathered roof of a cabin among the trees. A moment later, I touched down on level ground on a high point near the canyon, surrounded by prickly pear cacti, agaves, and scrubby creosote bushes.

Richard and I were both excited as I cooled off the engine and shut down. I marked my helicopter’s location as a waypoint on my handheld GPS and followed Richard toward the canyon. There were some cattle trails that wound back and forth along the slope and headed into the trees. One thing I’d learned about free range cattle is that they always know where the water is. Following their trail would lead us to the creek.

We began to see signs of long-gone occupation as soon as we got into the shade of the tall trees that filled the canyon. First a thick pipe, broken here and there, which must have carried water from the spring-fed creek. Then an almost intact wagon wheel lying among the broken remains of a cart, some old tools, and saw blades. We continued down toward the creek, our feet crunching over years of fallen leaves. We walked around a thick bed of what looked like irises and then came face to face with the first cabin.

A wagon wheel and some tools were the first signs of civilization we encountered under the canopy of trees.

I don’t know who built the cabin or how long it had been standing beneath those trees, but I know it’s old — perhaps a hundred years or more. Its sides were made of crudely shaped wooden planks, which had colored with age to warm browns and dark grays. The roof was corrugated tin sheets, laid almost haphazardly to provide the best coverage. A stove pipe came though a hole in the roof and another pipe led from the ground into the wall. Two windows faced out over the stream, which gurgled softly nearby.

Richard approaches the main cabin.

A small porch and open doorway faced us and we wasted no time stepping up for a peek inside. There were two rooms, a kitchen and a bedroom. Inside the kitchen, we found the remains of a wood-burning stove and a sink with a countertop. A firewood bin had been built into the wall between them. In the bedroom, a bed frame stood neatly against the window. Although the floor looked to be in remarkably good condition, especially in the bedroom, Richard and I thought it best to stay outside, where we were less likely to damage the fragile remains.

Beyond the main cabin stood a second, smaller cabin, which had probably been used for storage. That cabin was surrounded with a dense growth of vines. Had I been properly dressed in heavy jeans and hiking shoes, I would have made my way through the growth for a closer look. But my lightweight slacks had already been torn on the 1/10 mile hike from the helicopter to the cabins and my Keds did little to protect my otherwise bare feet.

The other cabin.

Despite our find, Richard was still disappointed. He told me that the cabins he and his stepfather had found had apple trees growing in front of them. There was no sign of the trees that day — just the thick vines that covered the ground with a narrow cattle trail running through them. Although I pointed out that the trees could have died and rotted away during the past thirty years, he wasn’t convinced. He was sure we had the wrong cabins, although he thought we might be close. So we set off on a short hike down and then up the creek. Other than the cabins and some old fencing, there was no other sign of occupation.

After an hour exploring the area, it was warming up. Three-Niner-Lima sat at 5,000 feet — an elevation that would have an impact on its performance, especially on a hot day. Thermal updrafts and winds would be starting up soon, too. I was anxious to head out before performance and turbulence became an issue. As Richard and I climbed up out of the canyon and made our way back to Three-Niner-Lima, we talked about returning another day, with a better camera and the proper footwear for me. I marked the landing zone with a row of white rocks and walked around my ship to make sure stray cattle hadn’t damaged it while we were out of sight. Moments later, we were airborne, heading out over the canyon to start a spiraling climb over the mountain peaks between us and Wickenburg.

Richard, who is retired, spent the next few weeks trying to dig up some information about the cabins. He found an old man who knew about them and told him that there had indeed been apple trees. But some city slickers out camping in the wilderness had decided to cut them down for firewood. That had been years ago and no trace of the trees remained.

No trace of the people who lived there remain either. Or of visitors like us, who come to look but take pictures instead of souvenirs. Although the coordinates of the hidden cabins are safely stored in my GPS, they’ll remain hidden, too. Too many places have been destroyed by heartless vandals, who take pleasure in rubbing out the traces of our state’s history. I’d rather let nature reclaim the site at its own pace than share the secret location of the hidden cabins of the Weaver Mountains.

The Big, White Tire

How I conquered the big, white tire.

In my essay, “When I Became a Pilot” (which has since been lost in various Web site changes), I discuss the various flights I’ve made that have led up to me finally feeling as if I really am a pilot. One of these flights was my private pilot check ride. And in one of those paragraphs, I mention the big, white tire.

The tire is a truck tire, painted white, that sits out in the desert in a practice area my old Scottsdale-based flight school sometimes uses. The area is about four miles northeast of Deer Valley airport (DVT). I’d tried on several occasions to find it, but was never successful. Until today, that is.

But I’m getting ahead of myself here. First you need to know the back story.

During my check ride, the examiner asked me to hover up to that big, white tire, face it, and hover all the way around it, facing it the entire time. This is an exercise in hover control and frankly, when I attempted it on my check ride, I did quite poorly. In fact, I thought I’d botched the check ride, mostly because of my failure to do this one maneuver anywhere near satisfactorily. I passed the check ride, but I vowed to return to the tire and try again.

Today, after a late lunch at Deer Valley’s airport restaurant, I decided to try to find the tire again. And this time, I found it.

It’s not very hard to find, if you know where to look. There are actually two big, white tires there. But more obvious from the air is the landing square, marked out with small, white tires and the orange windsock, which must have been recently replaced. Today, it hardly moved, with a two- or three-knot wind from the northwest.

I landed in the square, then hovered up to the big, white tire. I faced it with the tip of my cockpit only a foot from its closest edge and my skids only two feet off the ground. It seemed to mock me — after all, it was just a big, white tire in the desert, but it had been in my thoughts for years. It was as if I were making a pilgrimage to pay homage to its greatness.

And then I began my circle, to the left. It amazed me, at first, how easy it was to perform this simple task. Slight movement to the left with the cyclic, slight pressure on the right pedal, miniscule adjustment of the collective. Within half a minute, I’d circled it, returning to my starting point. Then, just for good measure, I circled to the right.

Ha! I could do it after all!

(Of course, I’ve logged over 600 hours since my first check ride. If I couldn’t do it by now, I should go back to flight school.)

I left the practice area, proud of myself. I flew low around the mountains of New River, over Anthem and the outlet mall, over Lake Pleasant and the golf course, into the Wickenburg Mountains. I flew low, a hundred feet above a car on Castle Hot Springs Road, past a man parked out in the desert with a camera, over some ATVers in the Santo Domingo Wash. I passed the shooting range and the rodeo grounds, then climbed to a respectable altitude to overfly Wickenburg. I came in to the airport on Runway 23, and set it down at the pumps, feeling more like a pilot than I have in a very long time.
