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 notes a resurgence in pilot/copilot seat slippage accidents in multiple Cessna models, suggesting inadequate adherence to AD 87-20-03R2 and inspections.
• New Cessna T210L flap follow-up cables are reported to operate roughly and intermittently, especially with required bends, despite manufacturer quality control claims.
• Kelly Aerospace overhauled DOFF10300 alternators show a high failure rate (approximately 70%) within 50 hours of operation, with recurring issues like broken studs and other defects.
