From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Pilot stated that he had made aproximately 3 aerial application flights in this aircraft from the same runway just prior to the accident takeoff attempt. Pilot stated that as he began his downwind takeoff with a 7KT, gusting to 14 kt tailwind, the aircraft veered to the left, and his application of required corrective full right brake and rudder was not adequate to stop the left yaw and resulted in his departure from the dry paved runway surface, with severe side loading of the landing gear. He remained at full power as he attempted to get airborne and straighten it out. However, the right gear separated from the aircraft, resulting in the propeller and right wing striking the ground, and separation of the engine / prop assembly as the aircraft came to rest upright. Due to the severed fuel lines and electrical cables from the engine separation, a post crash fire erupted immediately. The pilot exited the cockpit without injury and called 911 to report the accident and resulting fire, which was rapidly spreading in the dry grass between the runway and taxiway. The aircraft was partially consumed in the post accident fire.

As the FAA filed it

PILOT STATED THAT HE HAD MADE APROXIMATELY 3 AERIAL APPLICATION FLIGHTS IN THIS AIRCRAFT FROM THE SAME RUNWAY JUST PRIOR TO THE ACCIDENT TAKEOFF ATTEMPT. PILOT STATED THAT AS HE BEGAN HIS DOWNWIND TAKEOFF WITH A 7KT, GUSTING TO 14 KT TAILWIND, THE AIRCRAFT VEERED TO THE LEFT, AND HIS APPLICATION OF REQUIRED CORRECTIVE FULL RIGHT BRAKE AND RUDDER WAS NOT ADEQUATE TO STOP THE LEFT YAW AND RESULTED IN HIS DEPARTURE FROM THE DRY PAVED RUNWAY SURFACE, WITH SEVERE SIDE LOADING OF THE LANDING GEAR. HE REMAINED AT FULL POWER AS HE ATTEMPTED TO GET AIRBORNE AND STRAIGHTEN IT OUT. HOWEVER, THE RIGHT GEAR SEPARATED FROM THE AIRCRAFT, RESULTING IN THE PROPELLER AND RIGHT WING STRIKING THE GROUND, AND SEPARATION OF THE ENGINE / PROP ASSEMBLY AS THE AIRCRAFT CAME TO REST UPRIGHT. DUE TO THE SEVERED FUEL LINES AND ELECTRICAL CABLES FROM THE ENGINE SEPARATION, A POST CRASH FIRE ERUPTED IMMEDIATELY. THE PILOT EXITED THE COCKPIT WITHOUT INJURY AND CALLED 911 TO REPORT THE ACCIDENT AND RESULTING FIRE, WHICH WAS RAPIDLY SPREADING IN THE DRY GRASS BETWEEN THE RUNWAY AND TAXIWAY. THE AIRCRAFT WAS PARTIALLY CONSUMED IN THE POST ACCIDENT FIRE.
