Incident Details
The pilot of the aircraft stated that the left main landing gear collapsed during the landing rollout. When contacted by telephone for an interview, the pilot was asked when the landing gear had been placed down and what the gear safe indicator lights showed at touchdown. The pilot did not respond to these questions, only stating that he had followed the checklist. The checklist specifies that the gear should be down before 'when landing assured.'
Investigation Findings
Examination of the aircraft revealed rotational scoring on the painted surface of the left main gear actuator assembly. A further component teardown and examination found that the screw housing assembly of the actuator was bent. No other details were provided regarding the aircraft type, registration, operator, location, date, or any injuries or damage to the aircraft beyond the gear collapse.
