What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Pilot stated that after preflighting, the aircraft was boarded in preparation for flight. When the main battery switch was turned on, an aural warning was heard and thought to be the stall warning. The stall warning tab on the wing was actuated and it worked okay. The pilot then tried to isolate the problem by pulling circuit breakers. When the l/g (landing gear) circuit breaker was pulled, the aural warning stopped. The pilot decided to start the engines, and when the engines were at idle the landing gear breaker was pushed in and the nose gear immediately cycled up causing both propellers to impact the ground. Upon a visual inspection of the cockpit area by an inspector from this office, it was observed that the landing gear handle was still in the gear up position. A functional check of the landing gear revealed a malfunction of a safety solenoid which prevents the gear handle from being moved to the up position with weight on wheels. It is undetermined why the gear handle was in the up position prior to starting engines.
As the FAA filed it
(-23) PILOT STATED THAT AFTER PREFLIGHTING, THE AIRCRAFT WAS BOARDED IN PREPARATION FOR FLIGHT. WHEN THE MAIN BATTERY SWITCH WAS TURNED ON, AN AURAL WARNING WAS HEARD AND THOUGHT TO BE THE STALL WARNING. THE STALL WARNING TAB ON THE WING WAS ACTUATED AND IT WORKED OKAY. THE PILOT THEN TRIED TO ISOLATE THE PROBLEM BY PULLING CIRCUIT BREAKERS. WHEN THE L/G (LANDING GEAR) CIRCUIT BREAKER WAS PULLED, THE AURAL WARNING STOPPED. THE PILOT DECIDED TO START THE ENGINES, AND WHEN THE ENGINES WERE AT IDLE THE LANDING GEAR BREAKER WAS PUSHED IN AND THE NOSE GEAR IMMEDIATELY CYCLED UP CAUSING BOTH PROPELLERS TO IMPACT THE GROUND. UPON A VISUAL INSPECTION OF THE COCKPIT AREA BY AN INSPECTOR FROM THIS OFFICE, IT WAS OBSERVED THAT THE LANDING GEAR HANDLE WAS STILL IN THE GEAR UP POSITION. A FUNCTIONAL CHECK OF THE LANDING GEAR REVEALED A MALFUNCTION OF A SAFETY SOLENOID WHICH PREVENTS THE GEAR HANDLE FROM BEING MOVED TO THE UP POSITION WITH WEIGHT ON WHEELS. IT IS UNDETERMINED WHY THE GEAR HANDLE WAS IN THE UP POSITION PRIOR TO STARTING ENGINES.
