Transport Canada (TC) in late 2009 issued a Service Difficulty Alert detailing failure of a parked aircrafts control yoke that broke during high-wind conditions. A complete fracture occurred between the yoke pivot area and the elevator attachment point due to severe internal corrosion. A 2001 Cessna service bulletin provides instructions for creating an inspection hole, recommending annual inspection and corrosion treatment.
Key Takeaways:
- Several Cessna aircraft models (172/180/185, 208B, 340A, Citation X) experienced critical mechanical failures, including severe internal corrosion in control yokes and flap systems, and structural breaks in landing gear components and flap linkages.
- Additional reported issues involved a manufacturing defect in a new TCM cylinder (missing seal counterbores) and a failed gear shaft in a Slick Magneto, highlighting diverse component-specific problems across different aircraft systems.
