Broken And Cracked
Before a touch-and-go landing, the pilot noticed did not receive a gear-down light for the left main gear. A safe landing was made, with minor damage and no injuries. Upon examination, one of the left main landing gear actuator hydraulic fittings (p/n: MS20822) was found broken flush with the actuator housing. Examination of the gear well and the general layout of components show the flex hose may have been stress loaded while the gear was retracted.
Key Takeaways:
- Several aircraft incidents involved mechanical failures, including a broken hydraulic landing gear actuator fitting, a fractured camshaft, and recurring failures of starter adapters, possibly due to starter motor run-on.
- Improper installation of a lift strut eyebolt, with insufficient engagement, directly caused a loss of vertical control and a crash in one instance.
- A specific model of Dukes Fuel Pump demonstrated a high rate of recurring failures across numerous aircraft, indicating a potential systemic reliability issue with the component.
