romair Posted April 13, 2013 Report Posted April 13, 2013 While doing my pre-flight I have been noticing that when I move the ailerons by hand there is a significant difference between the left one and the right one. The left one is very easy to deflect upwards, and somewhat needing more force to deflect downwards. The right one requires about the same amount of to deflect upwards and downwards. What is striking is how easy it is to deflect the left aileron upwards. Again, this is by hand moving the ailerons, not by using the yoke. Its not a new finding, it has felt this way since I owned the plane, but it was only yesterday when I decided to actually compare the ailerons multiple times, just to make sure it wasn't something I was imagining. There is no difference in force needed to deflect the ailerons when using the yoke. Is this normal? Any thoughts as to what it can be going on? Thanks Stefan 1989 M20J Quote
romair Posted April 13, 2013 Author Report Posted April 13, 2013 I will check...but while that would explain the more force needed to get downward deflection, what about how easy it is to get upward deflection. The upward deflection is not only easier than the downward deflection, but significantly easier when compared to the right aileron as well. stefan Quote
M016576 Posted April 13, 2013 Report Posted April 13, 2013 Are your headsets hanging on the yoke? Stupid question, I know, but it would explain what you're feeling! Quote
jetdriven Posted April 14, 2013 Report Posted April 14, 2013 They are rigged together and it should be the same both ways. There is also a spring between the aileron center link and the rudder pushrod. If the rudder is not centered on the ground, the apparent force could differ from left to right Quote
N201MKTurbo Posted April 14, 2013 Report Posted April 14, 2013 You might check the autopilot servo, it could be giving you some trouble, it is attached to the left aileron. Quote
Mooneymite Posted April 14, 2013 Report Posted April 14, 2013 Before exploring the tough stuff....just make sure the nose wheel is perfectly centered. Quote
FloridaMan Posted April 14, 2013 Report Posted April 14, 2013 Before exploring the tough stuff....just make sure the nose wheel is perfectly centered. I came here to say that. Quote
N201MKTurbo Posted April 14, 2013 Report Posted April 14, 2013 The best way to find the problem is just do a complete lube job to the aileron system from the wing tips to the yoke. Don't forget the tube support blocks in the wing, give them a dab of grease. If you are not an A&P you can still do this. Don't lube any part of the servo except the rod ends going to the bell crank.
