One flight straight and level, next flight left wing heavy. Next flight not so bad. Seems to be the model of inconsistency. Should this be changing so much? Fuel levels, tank imbalances, passenger loading all should have much of an effect right? Most of the mass is near the longitudinal access of the airframe. The only thing I can think of is that maybe the flaps in the retracted position are sitting differently after each flight. Any ideas? ________________________________ Message 2 _____________________________________ Time: 11:16:52 AM PST US From: Linn Walters Subject: Re: TeamGrumman-List: Aileron Trim Is it tied down outside???

Seldom enough to ever require readjustment of the trim tabs though. Rain can affect aileron trim during flight though. Sometimes significantly.

Coming home from E45 (Pine Mountain Lake) last Sunday, even with heading auto-pilot, it wanted to fly left-wing low. Other times aircraft flies perfectly level. I have fiddled with aileron trim several times. On another issue, anyone have any idea why one of my EGT temps is 150 degrees less that others (1145, 1300, 1310, 1280)??

Try leaning the engine significantly more and see if the don't even out more. Do it at 3000-4000 ft and 2500 rpm and you can't hurt the engine no matter what you do with the mixture. Lean until it starts to run rough and then enrich just barely to smooth it out and see what your temps are. Cliff ________________________________ Message 6 _____________________________________ Time: 07:43:01 PM PST US Subject: Re: TeamGrumman-List: Aileron Trim From: teamgrumman@aol.com Larry, About 14 years ago, I flew an AG5B to Florida to deliver it to a new owner . I had picked up the plane in the Bay Area and flew it to Lancaster. It was 'out-of-trim.' So, when I landed, I gave the aileron tab a little tw eek. After the annual, it was out the other way, I landed, did a smaller correction and then reflew. It seemed ok. During the flight to Florida, I fought aileron trim issues the entire flight. I tweeked it every time I stopped for gas. I could not get the trim set right. At that time, I hadn't thought much about the flap rigging on the plane. On my plane, I have the flaps reflexed enough to cause a roll change based on flap setting. Works kind of nice to correct for fuel imbalance. I'm not sure it would work on all planes. Try tapping the flaps down a degre e at a time to see if you notice any change. It is true that passengers and loading will have an effect on roll; enough to be annoying.
