The NTSB's narrative final · quoted from the NTSB record
The pilot stated that he used the checklist and placed the landing gear handle in the “down” position, but did not check the annunciator lights. During landing, the gear collapsed. Postaccident examination of the airplane revealed that the landing gear circuit breaker had opened. Runway scrapes showed all three gears were partially extended when the airplane touched down, indicative that the gear extension was in progress when the wheels touched the runway. The airplane was placed on jacks and the nose gear was pulled down by hand where it locked into position. The right main landing gear was also pulled down by hand and it locked in position. The left main landing gear could not be extended due to spar damage, but testing of the squat switch revealed no anomalies.
