A technician submitted discrepancy reports for the same problem in six different aircraft undergoing annual inspection. Aircraft included an F33A Bonanza, V35B Bonanza, A36 Bonanza, a Model 55 Baron and two B95 Travel Airs. Of these six aircraft, total times ranged from 3144.9 to 5255.1 hours. The FAA noted, "This is awfully good anecdotal evidence arguing for close attention to these actuation attach points after a couple thousand hours."
Key Takeaways:
- Multiple Beech models (Bonanza, Baron, Travel Air) experienced cracked flap leading edge nose ribs, typically after several thousand flight hours, indicating a need for close attention to these areas.
- Various Cessna 100, 200, and 336/337 series aircraft show main landing gear fatigue, requiring visual inspections for corrosion, pitting, and cracking at or before 1,400 flight hours and subsequently at 100-hour or annual intervals.
- Other reported issues include leaking brake castings in a Cessna 208B due to casting porosity, a chafed and leaking fuel line in a Cessna 172S, and an inflight cabin door separation in a Diamond DA40F due to a detached latch rod.
