REFLECTOR: Aileron torque tube bearing

[Laurence Coen]

Al,

I only have 75 hours on my plane and just completed my annual and there was no apparent slop in the aileron torque tube bearing.  I can't imagine what would cause this kind of a failure in this application except a manufacturing defect.

I find that one of the aileron torque tube bearings at the bellcrank in the engine compartment has failed. It now has about 1/16" play, and slack in the controls is not a good thing. This seems a bit peculiar to me as the normal motion is slow and limited, and the normal loads minimal.  



Is this a unique occurrence, or have others had this happen?  The underlying question is vibrational loads; lateral or torsional, that may have some resonance - like in that 4-5 ft length of unsupported torque tube.
