Selecting the landing gear "down" produced an unsafe nose gear indication. Manual gear extension proved unsuccessful. The nose landing gear collapsed upon landing. Inspection revealed the nose landing gear linkage adjusting fork (p/n 5045211-2) had fractured, preventing extension of the nose landing gear to a down and locked position. Evidence suggests this fracture was progressive in nature, and some degradation to the components structure existed prior to failure.
Key Takeaways:
- Multiple aircraft experienced landing gear issues, including a Cessna 340A nose gear collapse due to a progressively fractured linkage and a Cirrus SR20 with a seriously cracked nose strut.
- Fuel system failures were reported, with a Cessna 208B experiencing multiple failed overhauled fuel pumps and a Mooney M20C's fuel selector valve seizing due to corrosion attributed to a design vulnerability.
- A Cirrus SR22 repeatedly suffered roll-trim actuator malfunctions caused by loose wiring.
