Wear And Tear
The right aileron was binding during aerobatic maneuvers. Investigation revealed the clearance between the aileron and the aileron bay rib was approximately 1/16 inch. Per American Champion, it should be inch. The inboard aileron bay rib appeared to have bowed due to fabric shrinkage, causing the interference. The aileron rib fabric was opened and the rib was relocated outboard 3/16 inch. Per the manufacturer, aileron balancing was not required. The aileron was reinstalled, with the clearance and operation satisfactory.
Key Takeaways:
- Various aircraft models experienced diverse component failures, including aileron binding due to fabric shrinkage, broken plastic rudder pedal bearings, and shattered starter end caps.
- Other issues included excessive wear on a nose gear steering mount and a prematurely broken magneto point contact arm.
- A key takeaway is the need for manufacturers to provide clear service limits and repair data for critical components, exemplified by the Piper PA34-200T nose gear assembly.
