Key Takeaways:
- Several aircraft are experiencing critical landing gear component failures, including bent and cracked nose gear torque links on Cessna 210s (possibly due to hard landings) and recurring circlip failures for main gear downlock pins on Diamond DA42s, leading to structural damage.
- Engine component issues reported include a severely cracked ECI cylinder head on a Beech A36, underscoring the need to follow ECI Service Bulletin 06-2, and new Champion oil filters (CH48110-1) failing due to element separation, causing immediate oil pressure drops.
