What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On April 29, 2011, prior to takeoff from the St. Petersburg airport (spg), the pilot tried to start aircraft N7760Y engines however, the aircraft battery did not have sufficient power to rotate the starter. The pilot requested and received a 12 volt jump start from the fix base operator (FBO) at the airport, but the power source was not sufficient to perform the engine start operation. The pilot then connected a 24 volt power source to the aircraft electrical system and used it to start the aircraft engines. Shortly after takeoff, the aircraft loss electrical power and the pilot return to spg for landing. He contact the tower and informed the controller that the aircraft had loss electrical power and requested a visual inspection of the landing gear to make sure they were down and locked. During the landing phase of flight, he stated that the tower gave him a red light but he did not see it before touching down. Shortly after touchdown on the runway, the landing gear collapsed which caused the lower section of the fuselage to come in contact with the runway causing minor damage to the undercarriage and landing gear doors.
As the FAA filed it
ON APRIL 29, 2011, PRIOR TO TAKEOFF FROM THE ST. PETERSBURG AIRPORT (SPG), THE PILOT TRIED TO START AIRCRAFT N7760Y ENGINES HOWEVER, THE AIRCRAFT BATTERY DID NOT HAVE SUFFICIENT POWER TO ROTATE THE STARTER. THE PILOT REQUESTED AND RECEIVED A 12 VOLT JUMP START FROM THE FIX BASE OPERATOR (FBO) AT THE AIRPORT, BUT THE POWER SOURCE WAS NOT SUFFICIENT TO PERFORM THE ENGINE START OPERATION. THE PILOT THEN CONNECTED A 24 VOLT POWER SOURCE TO THE AIRCRAFT ELECTRICAL SYSTEM AND USED IT TO START THE AIRCRAFT ENGINES. SHORTLY AFTER TAKEOFF, THE AIRCRAFT LOSS ELECTRICAL POWER AND THE PILOT RETURN TO SPG FOR LANDING. HE CONTACT THE TOWER AND INFORMED THE CONTROLLER THAT THE AIRCRAFT HAD LOSS ELECTRICAL POWER AND REQUESTED A VISUAL INSPECTION OF THE LANDING GEAR TO MAKE SURE THEY WERE DOWN AND LOCKED. DURING THE LANDING PHASE OF FLIGHT, HE STATED THAT THE TOWER GAVE HIM A RED LIGHT BUT HE DID NOT SEE IT BEFORE TOUCHING DOWN. SHORTLY AFTER TOUCHDOWN ON THE RUNWAY, THE LANDING GEAR COLLAPSED WHICH CAUSED THE LOWER SECTION OF THE FUSELAGE TO COME IN CONTACT WITH THE RUNWAY CAUSING MINOR DAMAGE TO THE UNDERCARRIAGE AND LANDING GEAR DOORS.
