Uneven Elevators

Tommy Castleman
 

Hi everyone,


Thanks for all of the replies on my last post (Q1 w/ Kawasaki 340). I was wrong about the engine type, though. It is a Kawasaki 440 that was built by AED. There's more information on my specific airplane if you look up the tail number on the internet (N4WH). I learned a lot.


I'm hoping this is something easy that an A&P mechanic would know how to fix, but I noticed that one elevator is not aligned with the other one. I suspect that something may have happened in the decade or so that it was sitting in garages.


I looked on the Q1 plans. I found useful information on how to install elevators, but I could not find anything about how to fix an uneven alignment. The port elevator is somewhere between 1/8-1/4 inches "up" when the starboard elevator is flush with the wheel pant. Has anyone had this issue before?


Thanks,


Thomas

Has the plane flown in that configuration?

Not that I'm aware of. I have reason to suspect there may have been damage.

I assume that plane has flown before?
To address a Roll tendency we typically tweak the elevators deferentially.

Please check that the attachment of the ailerons to the aileron torque tube is solid.  Any motion between those two will call for rebuilding the aileron.  You can hold the opposite aileron immobile while trying to move the aileron in question.  There may be a small amount of twist in the tubing/mechanism connecting the two aileron, but if the aileron tube is not rotating and the aileron is, you have found the problem.

The previous owner/builder might have rigged the elevators that way to correct for some roll trim. My Q-200 featured an elevator roll adjuster so as to make minor roll trim adjustments for pilot vs pilot and passenger.
