From: "Richard Lamprey" Thanks Bob, Jim and Heather, The article is very useful, many thanks for posting it. Great guidelines for assessing engine condition. I was a little surprised that so few responses came in regarding overhauls, given that about 180 Europas are due for them, according to the Rotax 'book'. But this might be encouraging, since other aviation authorities across the world might have less issue with it than we have in Kenya. In Kenya we have a very inflexible aviation authority, that now applies normal Certificate of Airworthiness procedures (what you would call an FAA annual in USA) to experimental planes. In spite of this thoroughness, there is a blanket ban on experimentals leaving the country to fly abroad in the region, because we might become un-airworthy once we have crossed the border. Part of the problem is that there are few of us around, and we dont have a unified body to represent us, and to set our own guidelines that would be accepted by the authority. Another part is that all forms of general aviation are seen as a rich mans recreation, to be regulated into the ground, with fee structures that literally double every year. I now have to pay USD 600/year as a blanket amount for landing fees at major airfields, even if I operate only out of farm strips. They wont give me a CofA unless I show that I have paid. So we have to go through the same inspection procedures as certified aircraft an impossible situation. Therefore, at annual inspection, they look at the engine log, and tell us that we have to abide by the book. This approach affects everyone, we find that private Cessna owners will now have to overhaul their Continentals every 12 years, regardless of hours flown, because there is a recommendation from Continental that this is done. Aah, everyone points out, this is for engines on the commercial register, not private planes. Doesnt matter, says the authority, even if you did just 50 hours/year, and accumulated just 600 hours over the 12, it must come out and be stripped down and overhauled (cost about USD 40,000). The owners of privately-registered certified aircraft are obviously battling this one, and the jury is still out, but this is what we have to deal with here. Consequently, many owners of experimental aircraft, who keep them on outlying wildlife and cattle ranches and never come to the big airfields, have opted out, meaning ... forget about annual inspections, just keep flying and away from the authoritys eye. Sounds like the on condition system elsewhere is so much better!!

I built an 'oven' out of 2in Polystyrene sheets and used an electric greenhouse fan heater turned up to max for heat. To maintain an even temperature I wired a thermostat from an immersion heater into the mains supply and poked the sensor probe through the polystyrene. Worked a treat.

It's a round sausage made out of vinyl using a 4" muffin fan to keep it inflated and a zipper to get to your stuff. I forget the exact dimensions but the aluminium tubes ate 10 feet long so it's close to that.BTW a YKK Zipper leaks very little pressure compared to Velcro. Inside I have a 1500 watt articulating heater and a small fan to keep the air inside from stratifying. I used a pyrometer or two from my hot air balloons to keep track of the temps as well as a digital probe style. We just drape some bubble wrap over the top to insulate a little better. Works great. I only have one pic. of it: http://www.europaowners.org/main.php?g2_itemId=27251 Here we have two thin wall aluminium tubes holding it opened as we were using it in the winter to keep new layups warm after we shut down the heat. All our post curing was done at Waynes home with no tubes. A small square of Duct tape closes the holes for the tubes. It stores in a bag smaller than a shopping bag. If anyone is interested I also sewed up a 10' wide by 20" long and 9 foot high tent that lives resident in my Tin hangar in NY. The sides are Velcroed in place and can easily be removed to turn it into a hangar (top stays put 9' off the ground). Wew have heat from our home made heat exchanger and air conditioning. Also is a sewn up was our paint booth. It rolls up to a big Q-tip when not being used. It has filtered air coming through a huge filter sewn to one side: http://www.europaowners.org/main.php?g2_itemId=27216 The pics only show it 10 feet long, but I can add extra to make it large enough to paint the fuse and glider wings. The idea is the large 30" fan is blowing in fresh air through the filter that is close to the size of the wall. The air is going very slow. Then I have an attic fan in the door with a furnace filter in it. The 30" overcomes the attic naf and pressurizes the tent. I have to be careful, we need to put a restrictor over some of the intaqke side of the 30" fan or it will make the tent so hard it will fail. I should really sew up a "horses ass" relief valve, just a 8" tube with a rubber band holding it closed. It hangs fro two 10' tubes and once inflated can easily support 50 or more pounds hanging from the tubes.
