Separations

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:

• Various Beechcraft models frequently experience cracked flap leading edge nose ribs after several thousand flight hours, necessitating close attention to actuation attach points during inspections.
• Multiple Cessna 100, 200, and 300 series aircraft are susceptible to main landing gear fatigue, requiring visual inspections for corrosion, pitting, and cracking at or before 1400 flight hours, and every 100 hours or annually thereafter, especially if operated with skis or on unimproved runways.
• Other reported issues include leaking brake castings due to porosity on Cessna 208B, chafed fuel lines on Cessna 172S, and cabin door separation in flight on Diamond DA40F due to a detached latch rod from a bent attachment clip.
