A Helicopter Repair Story

Including a happy ending.

On Tuesday, I flew out to Robson’s Mining World in Aguila, AZ. I was scheduled to appear there on Saturday for their anniversary celebration and I wanted to make sure my usual landing zone was in good shape.

It was a windy day and I was tossed around a bit on the 8-minute flight from Wickenburg (vs. a 30-minute drive). But the winds were calmer closer to the ground. I circled Robson’s once, then set down on what I thought was a spot closer to the road. Turned out, it was the same spot I’d occupied the year before. It just looked closer to the road from the air. The quartz rocks Mike and John had laid out in a line for me were still there. The idea was to land with the helicopter’s cockpit over the line. That would keep my tail rotor away from the bushes behind us. But since the bushes looked bigger than they had the year before, I positioned the helicopter a little bit closer to the road.

I cooled down the helicopter and shut down the engine. Then I went out to assess the landing zone on foot. I discovered that the quartz line was still quite workable for me. The bushes were farther back than I’d thought on landing. (I always estimate the helicopter’s tail longer than it really is.) So the landing zone was fine. No trimming would be required. That’s good because I don’t like the idea of cutting any desert vegetation unless absolutely necessary.

I put on my jacket — it was still quite cool at 9 AM — and walked through Robson’s front gates. The place looked deserted. I headed toward the restaurant, planning on having a piece of pie for breakfast. The door was locked but as I was starting to turn away, Rosa, who works in the restaurant, hurried out from the kitchen and opened the door. I settled down at a table and she talked me into having a real breakfast of bacon and eggs. She set me up with a small pot of hot tea and went back into the kitchen to prepare my food.

I had a few awkward moments when the teapot’s lid fell into my cup and became stuck there. If I’d been with someone, we would have been laughing hard. But I was alone and laughed at myself more quietly. I had to pour all the tea back into the pot and wait for the lid in the cup to cool and contract a tiny bit before I could get it out.

Rosa brought me a plate of fresh fruit — grapefruit, pineapple, grapes, and oranges — then disappeared back into the kitchen. I busied myself by reading the history of Robson’s and some information about the equipment and vehicles on display. When she brought out my breakfast a while later, I gobbled down the two eggs over medium, three slices of bacon, and two slices of wheat toast with real butter. (Don’t you hate when restaurants use mystery spread on toast?)

The person I was hoping to see there, Rebecca, wasn’t in yet. She lives in Wickenburg and drives out five days a week to manage the place. I saw her drive in just as I was starting the engine for the helicopter at about 9:45. Since the engine was already running and the blades were already turning, I didn’t shut down. I had another stop to make.

Aviation Weather 1.2.5

A Dashboard widget for pilots.

I’ve used this widget in the past and really like it. It uses your Internet connection to retrieve official TAF and METAR information for airports you enter into its interface.

From Aviation Weather 1.2.5 on Dashboard widgets:

About Aviation Weather Get current weather conditions as well as weather forecasts with the “Aviation Weather” dashboard widget. The widget shows weather data (METAR and TAF) which is used by pilots for their flight preparations. ”Aviation Weather” lets you choose any airport weather stations from its built-in database by either name or ICAO (4-letter) code. Data will be shown in its original format or translated into easy understandable texts. You can define up to 4 preset stations.

The preset feature is handy. Just program in the four airports you visit most and getting the weather at your destination is as quick as two clicks. Highly recommended for pilots.

Christmas at Howard Mesa – Part I

I was dreaming of a white Christmas.

On the Friday before Christmas, Mike and I loaded up the truck with a bunch of things, including some furniture, food, tools, Jack the Dog, and Alex the Bird. At about 9 AM, we headed north, to our property at Howard Mesa.

In Wickenburg, it was raining. It was the first time there had been enough rain there to actually get your skin wet for at least a month. Part of me wanted to stay behind and enjoy the weather. But the other part of me knew that it was likely to clear up in an hour or two and I’d just be disappointed. We don’t get many good rainy days in the desert and Friday was not going to be one of them.

Our path took us up Route 93 to Route 89, through Congress and up Yarnell Hill. We stopped at the Cornerstone Bakery for some fresh baked goods to munch on in the car and enjoy on Saturday morning for breakfast. It was a freezing rain there, but nice and toasty in the bakery, which was filled with the usual collection of locals.

Back on the road, we took 89 through Peeples Valley, turned toward Kirkland at Kirkland Junction, got on Iron Springs Road in Kirkland, and followed that to the first traffic light in Prescott. Then Williamson Valley Road to the Pioneer Parkway to Willow Springs Road to 89A. In Chino Valley, we stopped at Safeway, where Mike filled the truck with diesel and I hurried through the store to get veggies and a few last-minute food items. By this time it was snowing pretty hard, with just enough wind to blow the flakes at about a 30° angle to the ground.

Back in the truck, we followed 89A to Ash Fork, where we got on I-40 eastbound. The snow was sticking up there, coating the road with a thin layer of snowy ice. Trucks and cars were taking it easy, preferring a self-mandated speed limit of 35 or 45 MPH rather than the legal 75 MPH limit. It was slow going, but I’m sure it was better that way. Alongside the road, a light dusting of snow covered fields and trees. It looked more like Christmas than it has in a long while for me.

At the exit for the Grand Canyon (the third exit, the one that’s really for the Grand Canyon), we got off and followed Route 64 northbound. There was a lot of snow on the ground there but very few vehicles. Still, we both felt relieved when we reached the turn for Howard Mesa and began our last five miles of the trip. 20 minutes later, we were pulling through our gate while the snow swirled around us.

The entire drive, including the two short stops, had taken about 4 hours.

Inside our camping shed, the temperature was hovering around 35°F — which was pretty much the same temperature as outside. Mike turned on the gas and I struggled a bit to get the heater turned on. He unloaded the car while I turned on the fridge and started putting things away. Jack the Dog immediately got to work terrorizing whatever small rodents had made homes in the fire pit outside. Alex hung out in the truck where it was warmer. He didn’t come in until the temperature had risen to nearly 50°.

My first main task was to clean up after our unwanted lodgers — the mice. The shed has a mouse problem that we’ve tried everything to solve. The last time we were there, we’d gotten desperate enough to leave poison around. I had to scoop up what remained of it (only one of four pieces) before Jack came in. Then I had to uncover the furniture and get the vacuum going to suck up the mouse droppings that seemed to be just about everywhere. I used a lot of disinfectant cleaner on the floor and countertops. I took my time about it — there really wasn’t any reason to rush; I had all day. I had my iPod sitting in the iHome base, playing Christmas songs. Within two hours, I was pretty much done.

In the meantime, Mike was working in the bathroom on the plumbing. On our last brief visit (by helicopter during snow showers), we had discovered that most of the pipes had frozen and cracked. Mike had brought along pipes and connectors and tools to replace the broken pipes with new ones. The job required that he cut away one wall to access the pipes and do a lot of disconnecting. There was no running water in the shed and wouldn’t be until the pipes were repaired. Even the 5-gallon water cooler jug was mostly frozen; I had to light a candle under its spigot to get the water to flow.

I made us a hot lunch of canned chili with scallions and cheese, then washed up using water I boiled on the stovetop. It reminded me of the old days at Howard Mesa, when we’d camped out in our pop-up camper. That camper was wonderful on warm summer nights, but it lacked basic conveniences, such as a refrigerator or toilet. We’d use the tiny two-burner stove to heat water in the morning for coffee and washing up. During the day, we’d use those solar shower bags to heat water for showering and washing dishes. (They really do work in Arizona; we once had the temperature of the water in one of those bags up to 110°F — too hot to shower in!)

After lunch, I went on mouse cleanup duty on the shed’s little loft, which is where we sleep when we camp there. I discovered a place where they might be getting in; I’ll work on closing it up this weekend. Outside, the snow was still falling lightly. Everything was covered with a dusting of it. Jack the Dog was still hard at work at the fire pit, with the fur on the lower half of his body soaking wet. Oddly enough, it wasn’t windy, even though the weather forecast had called for wind gusts up to 28 MPH. A low cloud hung over the mesa, cutting our view to only a few miles.

Before the end of the day, Mike had finished replacing all the cold water lines. He connected the hose from one of our water tanks to the shed’s water line, turned on the pump, and pressurized the system. That’s when he saw the cracks in the hot water lines. We turned off the pump and disconnected the hose, then let any water in the lines run out.

The sun went down and it got dark. We brought Jack in. I made leftovers from home for dinner. The heater, which had been set to 85°F, had gotten the temperature in the shed up to a high of 64°. It didn’t seem that cold. We settled down on the sofa with my 15″ MacBook Pro on a folding table in front of us. I popped in a DVD from the first season of 24. We watched two episodes. We’d heard a lot about the show but had never actually seen it. So I’d added it to my Netflix queue (along with the second season of Boston Legal) and we were checking it out for the first time. Not bad. I can’t imagine watching it with commercials, though.

I slept badly. It’s the stupid hot/cold/hot/cold middle-aged woman thing, combined with the sounds of sleeping someplace different. It was pretty quiet when we first got to sleep, but at about 3 AM, the wind finally kicked up, blowing from the west right at the loft’s only window. I’d left the window open a crack — I’m always worried about asphyxiation in a closed space with a gas appliance running — and Mike had to close it. Sometime during the early morning hours, the wind shifted around to the northeast, which is the back side of the shed. It wasn’t blowing hard enough to shake the building, as it sometimes does. Just loud enough to hear it rushing past in the piñon and juniper pines scattered over our 40 acres. The sky had cleared and there were billions of stars out.

In the morning, the temperature in the shed was 43&degF with the outside temperature 28&deg. This was a problem. The heater was turned up, still set on 85°. As we moved around, making coffee and tea, washing up with water heated on the stove, we started finding drafty places. Around each window. Where the water heater sits against the outside wall. Around the edges of the door. I got my assignment for the day: caulk.

Mike decided he needed something from the hardware store to keep working, so we made a trip down to Williams, AZ. The town was remarkably busy for the time of year. I think it’s because the Grand Canyon Rail Road is doing a special “Polar Express” to the Grand Canyon each day and that’s attracting a lot of families. The town also sets up a real Christmas tree on side street off Route 66 and blocks off the street so visitors can walk around it. Nice.

We took care of business in the True Value hardware store, buying about $90 worth of stuff that included a new front door mat and weather stripping. Then we hit Safeway for a few things, stopping at the Starbucks counter on the way out for mocha lattes.

By the time we got back to the mesa, before lunchtime, a lot of the snow had melted. Mike got back to work and Jack continued his vigil at the fire pit. Sometime during the day, he started barking at something — we looked out the window in time to see an antelope hopping away across the road. One of the open range cows also came by, but since we’d kept the gate closed, she didn’t get into our property. (Cows have done a lot of damage at our friends’ place on the other side of the mesa, making us very glad we fenced in our entire lot years ago.)

Soup and sandwiches for lunch. The shed temperature was in the low 60s while it remained in the 30s outside.

I went through a whole tube of caulk on the windows. The shed was built with window frames that they’d stuck standard sized windows into. Unfortunately, the frames were about 1/2 inch too wide and tall for the windows, leaving a gap on at least two sides. They’d finished the outside of the windows with trim, closing up the gaps a bit, but they were still drafty. And one window leaked. I’d fixed the leaky window during the summer but had never thought that the gaps might cause drafts in the window. So I went to work with the caulk gun, which I’m actually pretty good at using. I ran out of caulk before I’d finished all of the windows, but I’d closed up the worst of the gaps.

Mike, as part of his pipe insulation procedure, had sealed up around the water heater with Fiberglas and foam insulation. I used garage door weather striping around the front door. The door was made to fit the shed and it doesn’t fit quite right. You can see light through the cracks around the door. Even with the thick rubbery weather striping, you can still see light in a few places. But it’s a lot better than it was.

Mike finished up all the piping by sunset. Hooked up the water again, ran the pump, and pressurized the system. No leaks. He turned on the water heater. I washed dishes from lunch. He cleaned up. Then he was ready for a shower.

Unfortunately, he’d waited too long. The outside temperature had dropped and the hose, which had never fully defrosted from the night before, had thickened up with ice. The pump was unable to bring in enough water. His shower was very short-lived. He stepped out, cranky and miserable. I was just glad I’d let him go first.

Getting water from the tanks to our camping equipment had always been a problem in cold weather. In the spring of 2004, I’d moved up to Howard Mesa in our horse trailer with living quarters, which also had a pump to get water from the tanks to the inside plumbing. Unfortunately, during the night the hose would freeze and the pump would try in vain to get the water out. That would run down the trailer’s battery and burn up the pump. So I had to turn off the pump each night and use the trailer’s internal water storage system for water. Not a big deal. Once every few days, I’d fill the internal tank so there was always water there when I needed it.

But here at the shed, we don’t have internal water storage. All the water has to come from one of the big tanks. The closest one is about 40 feet away. Because this is not a permanent setup, we didn’t dig a trench and put in a pipe. We use a hose. And the hose freezes every night, even though we do our best to drain the water out of it.

At least it hasn’t cracked yet.

Anyway, we spent Saturday night much the same way as Friday night. A nice hot dinner and two episodes of 24 on my MacBook Pro’s wide screen. The shed was much warmer — it had gotten up to 71°F by late afternoon. I slept well, waking about an hour before dawn. Outside, the moonless sky was bright with stars.

This morning, the inside temperature was 57°; outside it was 31°. I like to think it was my excellent caulking and weather striping that kept the shed reasonably warm overnight.

Today, Christmas Eve, I’ll finish cleaning up the shed — didn’t get much done in the bathroom with Mike making such a mess in there. Then we’ll put up the Christmas lights. Later, when it gets warmer, we’ll go for a walk around our fence line, making repairs and looking for castoff elk antlers as we go. It’s beautifully clear outside — I can see for at least 50 miles in every direction — and, as I write this at 10 AM, its already nearly 40°. It’ll be nice to get out. And I’m sure Jack the Dog is looking forward to a good run. He’s been going nuts every time the coyotes start howling nearby.

This afternoon, after a nice hot shower (got my fingers crossed), we’re going up to the Grand Canyon to meet some friends for dinner at El Tovar. Then dessert at our friends’ house on the other side of the mesa.

I’m looking forward to driving back to our place tonight, to seeing those red Christmas lights all alone in the middle of nowhere.

Flying in Snow Showers

Learning from experience.

We plan to spend Christmas weekend at our “camp” on Howard Mesa. We wanted to check the place out to make sure everything was okay before driving up there. It’s a three-hour drive but only a one-hour flight by helicopter. So, with about 5 hours to spare on Sunday morning before I had to do a presentation for the local writer’s group, we planned to fly up for an hour or two then.

We started checking the weather forecast on Saturday. Howard Mesa is between Williams, AZ, and the Grand Canyon’s South Rim (closer to Williams). The weather for both didn’t look good. Temperatures in the high 20s, high winds, and scattered snow showers. The three weather forecasts we checked (National Weather Service, Intellicast, and Weather.com) each had a different story to tell. NWS was most optimistic. Weather.com was most dire.

When the sun rose on Sunday morning, it illuminated a cloud bank that seemed to be passing over Wickenburg on its way northeast. To the north, the clouds looked low over the Weaver Mountains. But we could still see the top of Antelope Peak. The weather forecasts showed a front moving through. Show showers, winds 20 gusting to 30. But DUATS, a pilot weather service, didn’t paint as bad a picture.

I figured it was worth a try.

We got off the ground at 8:45 AM with full tanks of fuel and a few odds and ends we wanted to store in our shed. The winds at Wickenburg were light, out of the southwest. We climbed over the Weavers about 500 feet below the cloud bottoms. Ahead, the sky was dark with clouds that hung low. But visibility was good and we could see our next mountain landmark — Granite Mountain, west of Prescott. And we had a whopping 25-knot tailwind. So we kept going.

By the time we reached Granite Mountain, the sky ahead was completely overcast. We could see the Mongollon Rim and Mingus Mountain to the east. But to the north, the top of Bill Williams Mountain was obscured and the clouds seemed to be drifting downward. To the west, it looked like rain was falling. But to the east of Bill Williams, the clouds were higher and the way seemed clear. We could detour that way. So we kept going.

By the time we’d climbed the rim and were approaching the southeast side of Bill Williams Mountain, there were showers ahead of us. But they weren’t rain showers. They were snow showers. We flew into them and tiny pellets of snow pelted the cockpit bubble and mast. There was a dusting of snow in the forest beneath us. When I looked out at the fairing for the helicopter leg closest to my door, I saw tiny bits of white ice accumulating on the leading edge. Not a good thing. If ice were accumulating there, could it be accumulating on my rotor blades.

I have no experience with icing conditions, but I know icing is not a good thing. Yet the engine was running fine, my power setting was low, and the blades were behaving nicely. No loss of lift. We seemed okay. So we kept going.

Ahead of us, to the east of Williams, AZ, there were scattered snow showers all over the place. The sky and ground was a mix of dark and light. Occasionally, we’d catch a glimpse of blue sky through the speeding clouds a few hundred feet overhead. When the snow stopped, the ice on the skid leg fairing disappeared. When it started again, more ice appeared. We moved from tiny spots of sunlight to the deep, cool shade of low clouds. According to the AWOS, the visibility at Williams airport was 3 miles. We could see farther, but only in certain directions. Things were looking dicey, but according to the GPS, we were only 6 minutes away. Sheesh. How could I turn back? I could still see where I was going and there were plenty of places to make a precautionary landing if I needed to. So we kept going.

The worst of the snow showers appeared to be between us and Howard Mesa. We were less than 10 miles away and couldn’t see it. We started flying between snow showers, real scud running. I wish I had a GPS to track our path. We probably drew a line like a drunken sailor.

The six minutes turned out to be 10. The showers parted and we saw Howard Mesa before us. Then our neighbor’s house. Then our shed. I put on the brakes as I passed our windsock. It was hanging straight out. I turned into the wind and came in for a landing as a fresh show shower pelleted us.

It felt good to be on the ground.

We spent about two hours there, checking things out. It was a good thing, because some pipes were broken and we’ll need to bring tools and parts up with us for Christmas weekend to fix them. But at least we know what to expect.

While we worked, the weather blew around and past us. The wind had to be blowing at least 20 knots. Snow came and went. Some of the hard little crystals accumulated on the ground around the shed. I wanted to wait until things cleared up a bit before departing, but the weather wasn’t cooperating. It was a constantly changing scene, with snow showers and sun, with visibility ranging from a mile to five miles.

Finally, we could wait no more. We climbed back into the helicopter — which had remained ice-free — and I started it up. The weather around us must have changed 10 times while the engine warmed up. I kept changing my mind about which way we’d fly after takeoff. Finally, we were ready to go. I picked up and the wind hurried us through ETL. I departed to the west, which had the best visibility.

Now we were flying into the wind, around one snow shower after another. The scud running lasted almost until we reached Granite Mountain. Our path took us farther to the west than we usually flew, west of Ash Fork, Paulden, and Chino Valley. Visibility never got really bad — certainly not enough to make me worry. It was just an inconvenience. It took us an extra 30 minutes to get home.

It was my third experience with scud running — we really don’t get much bad weather here in Arizona — and when it was over, I felt okay. I never felt worried or as if I were out of control. There were always several options for getting to a safe haven, whether it was a clear place out of my way or a precautionary landing in a field. I think Mike and I learned a lot from the experience.

Back in Wickenburg, the wind was light. Big fluffy clouds floated by in a blue sky. No indication of the stormy skies less than 100 miles to the north.

Treadmill vs. Walk in the Park

Pros and cons.

I joined a health club recently. Wickenburg has an excellent “exercise center” that’s part of the Physical Therapy department at the local hospital. It has weight training equipment, elliptical exercise machines (is that the right name for those things?), stationary bikes, and treadmills. Just about all of it is computerized, so you can set goals and quantify many activities. The place is clean, there’s good music playing at a volume that’s not too loud to override it with iPod earbuds, and there are even televisions with captioning so you can read what’s being said onscreen.

Best of all, the members are an incredible mix of people, from the 20-year-old, skinny as a rail (as I was at that age) to the 40-something-year-old-who has had about five hundred too many cream puffs in her lifetime to the 90-year-old who comes in on a walker. I fit in nicely with this group, since I’m middle aged, overweight but not dangerously obese, and just enough out of shape to have to really work at my exercise regime, which is still in its infancy.

The treadmill is part of that regime — the warmup part. I start with a 20-minute session on the treadmill, using one of its built-in programs and setting the speed to about 3 mph. The programs change the machine’s incline, so I could be walking on flat ground for part of the time and climbing a hill moments later. Not a big hill, mind you. But one that’s enough to get your heart beating, which the machine monitors for you. In fact, if I enter my age and weight into the machine, when it gives me my heart rate, it’ll also tell me whether my work out is for weight loss or cardiovascular. I try to keep it in the cardiovascular range. I want to break a sweat, but not get soaked.

When I first thought about treadmills, I thought they were pretty dumb. After all, why use a machine to go for a walk. Why not just go for a walk? But I realized, after using a treadmill for about a week, that it does have some benefits over just walking. I thought I’d summarize them for people who have never tried one and, like me, wonder why they should.

There’s nothing to interrupt you while you’re walking.You can be interrupted by friends and acquaintances you pass along the way, traffic, or obstacles along the trail.

 

This is all I can think of right now. The conclusion I’ve reached from all this is that a treadmill offers an efficient way to walk for exercise. Efficient is good if you’re pressed for time and want to make the most of every minute. That’s me. Right now I’m walking at 3 mph (average) for 20 minutes as a warm up for other exercise, including weight training. During that time, I can burn about 75 calories (no Hostess Cupcakes in my immediate future) and get my heart rate up to 130+ beats per minute. But if I didn’t want to do weight training and wanted to base my workout around a good, long walk, I could easily choose a more difficult program at a faster speed and for a longer time, I can just push a couple of buttons, pick a good playlist on my iPod, and have at it. Nothing will interrupt me and I’ll get the workout I want.

If you live in Wickenburg and have been considering the hospital’s exercise facilities, I highly recommend it. It’s moderately priced — I paid $300 for 6 months, but that includes the “setup fee” to introduce me to the weight machines (and them to me via programming). A longer membership is cheaper per month; a shorter one costs more. But the way I see it, what’s more important: money or my health? I know I won’t walk or exercise regularly on my own. And I know I don’t walk as fast when I’m out with my walking buddies as I do on that machine. So I’m getting a lot of exercise each 90-minute session at the “health club.”

I must be. I slept 10-1/2 hours straight through last night.

And a side note here: I also started the Atkins/South Beach diet. I know they’re not the same, but they’re close enough for my purposes. I’ve lost 8 pounds in a week. Still very overweight, but starting to get back to the point where I can wear most of my jeans again.

And the way I see it, every pound I lose is one extra pound of passengers I can take flying. With some of my passengers so big they fully extend the seatbelt before fastening it around their midsections, somebody has to lose weight.
