New Parts, Old Problems

The FAA is encouraging owners and maintainers of Cessna T303, 336, 337 and all legacy, pre-1986 single-engine models to adhere to AD 87-20-03R2. The AD was issued because of pilot/copilot seat slippage due to the latch pin not properly engaging in the seat rail/track. The FAA states, "Compliance with AD 87-20-03R2 should have eliminated accidents and Service Difficulty Reports (SDRs). However, in the past decade we have seen a resurgence in the number of accidents [which] may indicate the inspections of the seat tracks are not being adequately performed or existing problems are not being corrected." The FAA strongly suggests reviewing AD 87-2-03R2. Cessna SEB07-5R1 or MEB07-1R1 covers secondary seat stop installation.

Key Takeaways:

• The FAA emphasizes stricter adherence to AD 87-20-03R2 for various Cessna models' pilot/copilot seat tracks due to a resurgence of slippage accidents, suggesting inadequate inspections.
• New flap follow-up cables for the Cessna T210L are reported to operate roughly, especially with multiple bends, complicating limit switch settings, a characteristic acknowledged by Cessna.
• Overhauled Kelly Aerospace DOFF10300 alternators show a high failure rate (approximately 70% for one shop) shortly after installation, with recurring issues like broken studs, loose hardware, and electrical faults.
