Alabama Winter Seaplane Survival Guide
December 15th: Flying floats for the next few months can be really rewarding without the challenges of other lake users. You must plan a little more carefully for your cross countries. Fuel will be more scarce as fewer marinas are open and since lake levels are down there are fewer and more treacherous places to splash in. More importantly, you should use the extra power afforded by the cooler weather and lower density altitudes to carry the necessities for an unplanned emergency landing.
During the summer months shorts and light clothing are the norm, But in the winter, exposure could be an issue in a very short time. Carrying supplies, a first aid kit, and warm clothing and/or blankets for emergencies is more urgent for any cross-country flight. Chances of quick rescue are good during the summer months on a busy lake, not so on a deserted winter lake. Be safe, be prepared, and enjoy winter float flying.

Winter Battery Maintenance
Pilot accessories such as portable GPSs, ANR headsets, handheld VHF radios, and flashlights are particularly susceptible to the cold winter nights. I take all of my battery powered pilot toys into the house at night, rather than leave them in the plane or even in the car trunk. Batteries drain fast when they have to light up frozen components. As a side benefit, you are removing an incentive for someone to pry open your airplane door to steal your goodies. So take care of your batteries and keep 'em warm.

Fall Seaplane Flying in Alabama
As days get cooler and the water gets calmer, it's really tempting to just fire up the engine and blast off. Be sure to taxi around long enough to allow the engine and oil to warm up to a reasonable operating temperature. Once in the air, enjoy the clear days and beauty of our great country. Most of all, appreciate the privilege and freedom of flight.

Things to do with a seaplane

Protecting the seaplane from wind and storms.
When I originally bought the plane it lived out of the water on a pontoon boat trailer. This got the plane out of the water, but left it vulnerable to trees, wind, and limbs. It also put the plane really high off the ground making it tough to tie down and tougher to preflight and fuel. The real clincher, though, was how tough it was to get onto the trailer in a high wind situation. Storms come up pretty darn quickly in Alabama. Usually the first indication is the gust front, and by the time that gets to us, we are already in trouble for threading the needle to put the plane on the trailer. It sits best on the trailer with the tail towards the trailer tongue, so that means a turn around on the water as well. I never had any issues or damage while doing these manuevers, although I personally got wet a few times. It became clear to me that I needed to keep the plane closer to the water and better tied down.
I built a U shaped dock to hold the plane which gave me multiple points to tie it up and tie it down. I then built a ramp in the middle of the slip and attached a winch and cables to lift the ramp/platform and the plane out of the water. This whole deal cost me a couple of weekends and about $2,000 including the wood, floatation foam and the winch. I was very proud of my engineering feat when I finished. This dock has provided me and the plane with years of protection and support. It has held up through several hurricanes and countless storms and boat wakes.
I am about to need a new winch, and my cabling corrodes and gives out every two or three years. The dock provides a great place to work on, fuel, and preflight the plane, and it has multiple points for tie downs. The support platform keeps the floats mostly out of the water and it keeps them stationary to the dock. When docking the plane, the platform acts like a ramp and keeps the floats from bashing into the back of the dock. The dock also weighs enough to hold the plane down during a storm, so it is secure at the dock. I can relax a little more when I hear about storms heading for Lake Martin. I still worry but just not quite as much. I still wish for a hangar.

Protecting the seaplane from the Alabama sun
Our avionics and our bodies don't care much for heat either. UV rays also attack our upholstery and interior plastics. I use a cabin cover which I bought from Bruce's Custom Covers at http://www.aircraftcovers.com.%20these/ are very durable and easy to put on and take off. I have tried other brands which can be cheaper, but they were not as sturdy and they fell apart after just a few years.
The covers protect all of the glass in the plane as well as reducing the internal temperatures. I suspect it even helps prevent hail damage to the windows by providing a barrier. I have one of these covers for the Twin Comanche as well ,and when I have to park the plane outside for even a few hours, I install the cover to keep the plane from getting too hot during the warm months. I still wish for a hangar, but at $350-$400 vs $50,000 for a hangar, as well as easy on and off, the cover just has too many plusses.

Seaplane Passenger Briefing
The briefing should cover the necessary topics while emphasizing the safety benefits of seaplane flying. On the positive side, seaplanes have several distinct safety advantages over land planes. To begin with, on Lake Martin we have about a 22 mile long runway ahead and 44,000 acres of runway below us almost the entire flight.

Mooring Strategies
Never assume your airplane is going to stay exactly where you put it while it's on the water. My plane is fairly secure at its specially built seaplane dock, which raises it out of the water and provides multiple solid tie downs. If it's anywhere else, I am never really at ease.
Strange docks are probably the worst. You never know how well anchored their cleats are going to be, or how rough the structure of the dock will be on the floats (be wary of objects below the surface that can jab at the sides of the floats). I am also nervous about other (especially pontoon type) boats that have roofs that can hit my wings. Boaters are not accustomed to other boats having a 12 foot overhang out to the sides. So I worry about these roofs denting my wings, ailerons, flaps etc.
Beaching is another matter. If the wind is blowing directly into the beach, you are in better shape but otherwise you need to check on the plane all the time. I had one instance this summer when I went back to the plane, and a pontoon boat was in the place I had beached my plane, and the boat was using my rope still tied to the tree that I had tied off to! My plane was nearby but loose, and fortunately the wind was keeping it at the beach. I can't imagine doing this to another boat. When we take the plane to lunch dinner in the plane, I usually check on it every 15-20 minutes.
During the drought of 2007, I had to leave the plane at the beach for nearly 8 months, while the water kept going down and then while the water came back up. I had to move the plane every 2-3 days. As the water was going down, I had to move the plane out deeper to keep it from being stuck for the rest of the season on the beach. I would keep one line on the tail cleat and one on each wing tie down attached to a large auger type tie down screw. When the water was coming up. the danger is with the tie downs over stressing the wings by pulling down while the floats are pushing up. The other fear is that the plane will pull the screws out of the ground and thus be free to float away. This up and down issue can also be an issue in coastal regions where the tide may change several feet in the coarse of a day. A floating dock or constant attention are really the only options.
The seaplane base at Oshkosh uses bouys achored to the lake bottom. A line is tied to the front of each pontoon and the planes are allowed to rotate into the wind. This assumes a pretty protected area, a secure bouy and that your floats don't leak too much.
The best sollution is to get the plane out of the water, but that is not always possible or convenient.

Seaplane Right Of Way
A vessel towing anything is supposed to have ultimate right of way. Sail boats and unpowered craft come next on the food chain. Then there are power boats. The fact is that we are much less manueverable than a power boat. Most seaplanes do not have reverse. We have no neutral. We have limited steering. While on the step (high speed taxi) we have even more limitted steering and stopping options. While in the plow attitude even our vision is limitted by the nose of the plane.
This only matters if the other boaters know or recognize our challenges. Unfortunately, this is not the reality. The other critical fact is that boaters greatly outnumber seaplane pilots. They will have a much better chance of getting us kicked off the lake than we would have of getting them to recognize we are not a threat to their safety and happiness.
Part of being a good seaplane pilot is to learn to be defensive if not transparent in all our actions. Don't fly low over houses and boats. Don't fly super early in the morning. Don't do anything that might scare the other boaters. Give way whenever there may be a question. I have heard boaters worry that a seaplane might lose control and crash into their pontoon boat on landing. I have no easy way to educate thus guy, and there are thousands more like him. Our best course of action is to expose these people to as many good examples of seaplane courtesy as we can.

Seaplane Landing Issues
Simply landing or taking off from the water changes it. It creates waves that can last for hours. By the same token, there are few things in flying more satisfying than executing a perfect glassy water landing. Every landing and every day is a learning experience and a new piece of water conquered. Yesterday I was eying the river below Lake Martin. It was a perfect sheet of glass. I setup to land and as I was coming down I started noticing debris in the water and lots of it. It was mostly tree limbs and sometimes whole trees. I aborted my landing. Recent rainfalls have been pounding the state, causing the rivers to swell.

Responsible Float Flying
Most people living on the lake appreciate calm, quiet days, and almost none of them bought a lake house to be under an airport traffic pattern. Most of the comments I get from lake users are positive and they think the seaplane is pretty cool, but I am very careful not to frighten or annoy anyone.
Most of the time the seaplane attracts its own trouble. We will do two or three landing before boats start to congregate to watch the seaplane. The simple solution is to wave to the boaters and find a new place to play. During the summer and on busy lake weekends I try not to stay in one spot too long anyway.
There are many un-inhabited areas of the lake. Sometimes one side of the shore has houses and the other side does not. It is very easy to use a right hand pattern instead of left to use the side that does not have houses. Simple, painless and effective, but you do have to think about it to make it happen. I am also really carefull not to fly directly over houses climbing out when the engine is screaming. Just a few simple thoughts can keep a lake open to seaplanes.

Float protection at the dock
One problem with floatplanes and docking is that fenders (boat bumpers) don't protect the floats. Why? Because the fenders float and the wide parts of the floats are actually below the water line. Here's a solution that actually will also keep the seaplane away from the dock and keep some light tension on the bow and stern ropes. Take a standard cylindrical boat fender and tie enough weight to the bottom of the float to just sink it. Attach a rope to the upper end of the fender and tie it or hook it to the wing tie down with enough length to set the fender next to the widest part of the float . The rope pulling on the tie down will actually pull the plane away from the dock thus providing a buffer zone.

The Mind of a Pilot
Judging wind direction and velocity
Basically, the water on the windward side of the lake is glassy while the other side of the lake has increasing waves going up to the shore. Judging velocity takes a little more experience and depends on the fetch, which is the length of the lake from the windward shore to the leeward shore.
The waves increase from the windward side to the leeward side. Glassy water indicates winds less than 3 mph. Small ripples indicate 3-7mph. Medium waves without white caps indicate 7-10 mph. Some white caps indicate wind less than 15mph. Lots of white caps indicate more. All of this is for a fetch of about a mile in length.
Using bodies of water for your wind indication can be done at altitude and does not require a low pass over the airport to see a tiny windsock. In addition, the water is not likely to be affected by hangars and other airport structures as many windsocks are.

Pilot's Fear of Doctors
We as pilots do what many people would consider a daredevil sport. Operating a machine thousands of feet above the ground with nothing but invisible air keeping us from our doom. When the time comes to meet our medical examiner for our medical renewal, we all have some trepidation. I usually try to see my regular doctor before meeting with the FAA designated medical examiner, (AME) just to see if there is anything to worry about. I have generally been pretty healthy over the years, but one bad reading from the AME and I cannot fly. Once the exam starts the die are cast. You can discontinue once something is found, and come back another day for a try. All this has a tendency to raise blood pressure, which is another trigger point with the FAA. Too high no fly. My BP is generally pretty normal except when at the AME. I have pilot frined who have issues with their hearts or diabetes or cancer. These guys really have it tough. They can get a medical but not without extra tests and waiting for month for an answer from the FAA in Oaklahoma City, sometimes just to get a letter requesting more information. Many of these people you would never suspect that they have an issue.
I have a commercial medical which means that I go through this process annually. I always feel better after I leave the doctors office. (so far). I can fly for another year, unless something bad like cancer gets me in the mean time.
There is one other option. In the past few years the FAA has created a Sport pilot certificate. This one only requires a drivers licence and self medical certification. It also limits the kinds of airplanes that you can fly to the smaller, slower, and simpler breeds. Pilots that have higher certificate ratings like private, commercial, or ATP can fly as sport pilots in sport qualified planes as long as they did not fail their last medical and they are generally in acceptable health. A bit of a catch 22.
The only other option is to fly gliders or ballons. These craft do not require a medical to operate. This is my backup plan should all else fail.

Rejuvenation - The Flight Home
Once we reached 50 kts I began to raise the pitch. According to the truck driver we hit 70 mph before liftoff. The plane came easily off the trailer and climbed and accelerated nicely. I lost contact with my ground crew by radio shortly after takeoff. My partner in the Twin Comanche, Allen, was going to follow me to the lake, but since we could not make radio contact he went back to Bessemer. The flight to Lake Martin was about 45 minutes.
About 15 minutes into the flight I started getting a random 200 rpm drop in engine speed. The drop kept coming and going. I was 10 minutes from Lay Lake so I continued the flight and kept my eyes out for suitable landing spots should things go badly. The drop turned more rhythmic as I got to Lay Lake. Once over the lake I climbed to 5,000 feet. I could see Lake Martin and I felt that I could make it. I had people on the water at Lake Martin. If I landed in Lay Lake on untested floats it could be ugly. So I made the journey home. The engine did not get any worse, but I was sure glad to see my home lake and my buddy waiting for me in the pontoon boat. I had not landed a seaplane in 4 months, which did not help my stress level. Neither did the fact that the float skins were new and untested. I set up and landed near my buddy and then taxied straight to the dock to do another leak check. Once at the dock, I called everyone to inform them that I was good. The rejuvenation project was finally at an end and I could sleep well. The issue with the rpm drop turned out to be a bad ignition lead. I bought a fresh new harness from Aircraft Spruce. If you would like to see the video follow the link-www.waterwings.com/video.html
It was very sweet to finish this project and land back into Lake Martin. Thanks to Erol Kyzer and Allen Taylor for the videography and Kevin Williams for the metal work and paint job on the plane. The airplane design is by Anna Welden (my daughter).

Rejuvenation - Skining the floats
It took as long or longer to pull the bottoms off as it did to replace them. Once the skins were off we could really inspect the insides of the floats. They were really in pretty good shape. We also decided to replace the middle and front bulkheads. One was dented really badly, and the middle bulkheads were pretty corroded. Now was the time to do it while the skins were off. This process took about a month. We ordered new parts from EDO, the float manufacturer, and Peck Aero Products in Canada. http://peckaero.com/ Ed Peck owns the operation and he was very very knowlegable and helpful. He even offered to reskin the floats for me. I winced at the thought of all that shipping and delay. In hindsight it might have been a good plan. We learned many lessons pulling these things apart and putting them back together that I am sure Ed learn a long long time ago and not at the expense of my time and the quality of the job that we did on my floats. I had lots fo bonding time with my mechanic and I learned a ton. I probably spent $3250 on float parts. They were all very pretty and shiney and new when they arrived. We used the old skins for a template for the new ones and we got to drill thousands of new holes in these very shiney and new parts. Once all the holes were drilled we started assembly. This was very exciting to see. I had witness so much destruction as the dead parts were removed and now they were being replaced with shiney new parts. When the float skins come off the float loses a bunch of its strength and the become flimsey. As the new parts were added back on everything became strong again. Very satisfying. I was starting to get the itch to fly the plane really badly now. All the ribs and doublers were added to the bottom skins before they were applied to the rest of the float. This made the rivets much easier to install. There are only about 40-50 rivets that have to be installed using two people. One person is on the bottom of the float shooting the rivets while the other is reaching in through the inspection hole trying to buck the rivet. Doing all of this you end up covered in sealant as well. We used latex glove for most of this process and the sealant would really stick to everything. The sealant is a two part substance that actually mixes inside the tube and it has a relatively short shelf life of 6 weeks and a working time that you can choose when you buy the tube. Some of the stains from the sealant will be a part of my wardrobe for years to come.

Rejuventaion - The windows
I chose a clear windshield that is 0.187 inches thick without the compass mount. The color choices are clear, green, or grey. In retrospect, the compass mount would probably have been a good idea. When we mounted mine my mechanic actually mounted it crooked. I spent many sleepless hours that night worrying about how to remove the mount and replace it. I reality, it came off easily since we used the wrong kind of glue to start with. The windshield came out pretty quickly compared to the rear window. We removed a bunch of screws and pulled. Then we cleaned all of the putty out of the channels that the window came out of.
The rear window was riveted in, which meant we had to drill out all of those rivets. This took another several hours. After lunch we put the new rear window in. We applied the supplied felt to the window and put fresh sealant in the channels that hold the window and then we shoved. This was an ugly process with lots of grunting and maybe an expletive or two. There is no good place to push or pull on the window and the channels are very tight. The window has to fit ALL the way into the channels or it will not fit properly at the bottom, where we had to rivet the hold-down piece back in. Once the window went in, it was time to rivet. This is a loud process in general, but inside the plane, bucking the rivets while my mechanic shot the rivets from the outside, was truly terrible. I wore my Bose headsets with the ANR on. I don't think they were designed for this but it was way better than nothing. The windshield went in easier. At least I was not involved in the process as we ran out of time that day. It is really nice having new glass, and from a cost standpoint, this is one of the cheaper improvements ,especially considering the benefit.

Rejuvenation - The evaluation
We are at the point where the paint has been removed. The plane is naked and the floats are separated. We had to use a crane to lift the plane and remove the floats. I think it is shivering a little from shyness. It's time for a thorough inspection of the skin. The airframe was free of corrosion and cracks. There were a few rivets in the wings that needed replacing. We even pulled out the entire interior, cleaned and inspected everything inside and out. This was also an opportunity to re-zinc chromate everything inside, then we repaint all the exposed surfaces. This was very exciting since I have spent a thousand hours in the plane thinking that it would be nice if the paint were not worn off some of these parts.
The only parts that really needed love were the floats. These were original with the plane when it was new back in 1967. The airplane spent a number of years as a land plane while the floats sat in storage. As far as I can tell from the books, the plane was not put back on floats until the mid-80s, when it was painted and upgraded to a 150 hp engine. I think that was the last time it was on wheels. These floats have been in the water or near the water for the last 24 years. That is a huge amount of time and wetness to cause corrosion. The worst of it was at the step area and the skeg, the deepest part of the float. The skeg and the bottom skins on the front half of the floats needed to be replaced. This is a terrible and expensive process. So we began locating the parts that we would need. At least we had a new plan. The old plan which was to only clean and paint the plane was out the window. This float project would take lots of time and effort. We would work on getting the fuselage and wings prepped and ready to paint while parts arrived for the floats. We would also spend a good bit of time taking the floats apart.

Rejuvenation -- Stripping the plane
There are several chemical methods to strip paint and these are the most commonly used. The other option is sanding, but that is hard work and hard on the airplane. We were looking for a quick and environmentally clean method. We chose to strip the plane using Soda Blasting. http://www.ibssodablasting.com/ This is kind of like sand blasting but using much more delicate baking soda. The process took two days and cost a little over $3,000. I felt that this was expensive, but it was fast, effective, and environmentally safe. The surface of the blasted plane was very nice for paint application. Once the blasting was done we went over the entire airframe and floats to look for damage that needs to be repaired. Can you feel the pain of my wallet?
Time for Rejuvenation-taking the plane out of the water
The first step was to drain all the fuel from the wings, otherwise it would be messy when we removed them. This took about 30 minutes. While that was happening the mechanic, Kevin, started unhooking things like control cables and flaps. Once that was done we stood precariously on the bed of the truck holding the wing tips while Kevin took out the four bolts that connect each wing to the plane. Two hold the strut on and two hold the wing root to the plane. In about 3 hours we had everything dealt with and I watched my dearly loved plane drive away. It would be months before I could fly it again.

Flying the new Cub Engine
Today we finished the installation by safety wiring the prop and running up the engine. For the first run-up we tied the plane to my truck, since the brakes on a Cub would never hold the plane at full power. It was also a precaution, in case there was an issue with the throttle. Before starting the engine, we had to prime the oil pump by spinning the prop with the bottom spark plugs removed until we saw oil pressure.
Once everything was set up, verified and secured, we began the process of starting the plane. I sat in the cockpit to hold the brakes while my mechanic propped the plane. With everything new and tight we expected the engine to be hard to start. It was. Once we got it going though and verified oil pressure, it was a great sound. Once the oil was warmed up, we ran it up to full power. It was obvious that there was much more power than the old engine. This one pulls 200 rpm more than the old one. One of my concerns was that my prop would need to be re-pitched to keep the RPMs below the red line for the engine. I still have a margin. After the run-up we shut down and put the cowling on the plane. It was time to fly.
Taxiing out to the runway it was interesting getting used to the new sound of the engine idling. It has a very different sound from the old one. The wind was calm and the sky was clear. Perfect. I did another pre-takeoff run up, and I taxied onto the runway. As I advanced the throttle, everything felt normal until about halfway to wide open. There was a rush of power that I had never felt in the Cub. It leapt off the ground as usual in about 200 feet, but instead of slowly climbing out, it was really climbing nicely. I was at pattern altitude by the time I was ready to turn downwind. There was never a question of making it back to the runway if there had been an issue. I climbed to 3,000 feet and hovered over the airport for about 20 minutes. The oil temp and pressure were stable so I decided to see what kind of climb it had beyond 3,000 feet. I took the plane up to 7,500 feet. It would have taken most of a tank of gas to get to 7,500 feet with the old engine. After 45 minutes, I started down. This engine upgrade has really given the Cub a new and interesting capability. Wahooo....
