Subject: Pietenpol-List: Routine Maintenance I just thought I would send along some info on a few of the items I am addressing, and maybe spark a discussion of what you other guys do as routine maintenance. I have just over 300 hrs on 'er now. I removed the exhaust pipes to sandblast, paint (white again), and wrap the upper portion of the pipes with insulating wrap from Thermo-Tec, for tworeasons:1. Better exhaust scavenging by maintaining a higher temp in the exhaust gases, that exit the system faster through decreased density.2. Make More and Better Smoke !! If the mineral oil is more completely vaporized through higher temperature, it will make more smoke, and leave less residue on the airframe. Remove the spark plugs for sandblast, inspection, and check gaps. Before sandblasting, the plugs had a nice medium to dark gray color, except that I found that #2 cylinder has some oil residue on them. The plugs will be re-installed in the next higher cylinder, and switched from top to bottom. After first flight of the year, I'll do a compression test and change the oil. Remove the Slick mags for clean, inspect, and check the gap. I also hada slight oil leak at the gaskets of the mags, which I'll use a very thin application of Hylomar - gasket & jointing compound. It's not silicone, but looks and feels similar. This stuff is manufactured under licensee from Rolls Royce...so it can't be all that bad !! Remove all the valve covers (slight oil leak) for clean & inspect, and give the gaskets the same treatment with the Hylomar. Fabric and paint the fixed trim tab on the rudder, and re-do the re-inforce patch where the rudder cables and flipper cables protrude the sides of the aft fuselage. Jack up the plane, deflate the tires, pull the wheel bearings for clean and inspect, remove the tires from the rims and turn the tires around end for end, because of the camber wearing the outer half of the tire tread - I havesplit axle gear. Fabricate and weld some stops on the torque tube, for 32=BA up travel and 25=BA down travel of the flippers. Before first flight of the year, I'll loosen the prop bolts, re-torque to 17 ft. lbs, and re-saftey. I do this 2 or 3 times a year. Pull every inspection cover on the plane for inspection with a mirror and a bright flashlight. Two drops of oil on all hinges, bearings, and spring gear. Clean and inspect the entire fabric surface, and wax the leading edge of the wing, and wax the prop...might even wax the car. This inevitably is just a partial list of to do's. What do you other guys do ?Chuck G.NX770CG________________________________________________________________________________

Subject: Pietenpol-List: Cutting the Toilet Paper I've been playing around with putting up a short clip on Youtube video. You folks that have high speed connection might get a kick out of the 4 minute clip I put together. I did a mixture of music and engine sound.Here is the link : http://www.youtube.com/watch?v=sz-IUf5oex4Chuck G.NX770CG________________________________________________________________________________Subject: Re: Pietenpol-List: Routine Maintenance

ChuckJust did my annual inspection before the winter and decided to make achecklist for this (see attached)(See attached file: Pietenpol Air Camper anual inspection.doc)As the weather has been pretty bad lately, I have decided to replace someengine components and to enlarge the wind screens.Termotec is pretty good stuff, I have it on my exhaust tubes, to keep heatout from under the cowling.Termotec is not flammable but can soak up oil.You might smoke from unwanted placesHansNX15KV________________________________________________________________________________Subject: RE: Pietenpol-List: Routine MaintenanceDate: Wed, 21 Feb 2007 10:19:14 -0500
