Post-Accident Examination
An FAA inspector examined the accident site and aircraft. The landing gear circuit breaker was found in the open position. Runway scrapes indicated that all three landing gear were partially extended at the time of the accident. The aircraft was subsequently placed on jacks. The nose landing gear was manually extended and locked into position. The right main landing gear was also manually extended and locked. The left main landing gear could not be extended due to spar damage. Testing of the left main landing gear squat switch indicated normal operation.
