Cessna 152 Broken Flap Cable “On final,” states an unidentified submitter, “the student selected 30 degrees flaps; a loud pop was heard, the r/h flap came down to 30 degrees, but there was no movement at the l/h flap. The aircraft landed without incident. Investigation revealed the swaged ball end broke from the remaining cable (p/n 0400107-146).” The submitter suspects high time and cycles as contributing factors to the failure. Part Total Time: 12,872.0 hours. Beech A36 Bonanza Loose Autopilot Connecting Rod A submitter writes, “The autopilot hook-up rod should be tightened up or removed from the aircraft at the factory. This is the second aircraft in one week (in which) this rod (and/or its attachment nuts) has been found loose.” The elevator control bell crank is p/n 002-524024-51. Part Total Time: 140.0 hours.

Key Takeaways:
- High-time aircraft components, such as a Cessna 152 flap cable and a Cessna T207A horizontal stabilizer fitting, are susceptible to failure due to wear and accumulated cycles.
- Recurring issues, like a loose autopilot connecting rod on a Beech A36 Bonanza, suggest potential factory assembly concerns or the need for more stringent initial checks.
- Piper PA34-200 aircraft exhibit common problems with worn landing gear mount holes and loose hardware, which can be mitigated by upgrading to stronger nut-plates and implementing regular inspections.
