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of the gear well and the general layout of components show the flex hose may have been stress loaded while the gear was retracted.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:
- Mechanical failures included a Glasair II SGR's broken hydraulic actuator fitting, possibly due to stress from a flex hose, and a Quicksilver Sport 2S's failed lift strut eyebolt caused by improper installation with insufficient thread engagement.
- Recurring component issues were identified with Continental TSIO-520-NB starter adapters, which failed rapidly after overhaul due to clutch spring damage, potentially from starter motor run-on.
- Dukes fuel pumps exhibited a high rate of recurring failures due to insufficient pressure across multiple aircraft, and a Lycoming IO-360-C106 engine experienced a broken camshaft originating from a stamped part number.
