The airplane received substantial damage to the left aileron. According to the pilot, a mechanic discovered the landing gear motor circuit breaker had popped, which disabled the landing gear from fully extending and lock in the down position and disabled the warning light system. Once the circuit breaker was reset, the landing gear functioned normally.
