Incident Overview
During the landing rollout, the left main landing gear and the nose landing gear collapsed. The pilot, in his report, stated that he does not recall manipulating any switches during the rollout. However, after exiting the aircraft, the pilot noted that the landing gear relay was tripped open and the flaps had been retracted.
Post-Accident Inspection
A subsequent inspection of the landing gear following the incident did not reveal any mechanical failure of the gear or its components.
Summary of Reported Facts
The pilot's account indicates no memory of switch activation during the rollout. The observed condition of the landing gear relay and flap position after the event suggests an uncommanded configuration change. The absence of mechanical failure points toward an electrical or operational anomaly.
