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.

Note: all witness statements are as seen from the ramp area at kagc facing north looking at the left side of the aircraft on landing and rollout. Witness stated: the aircraft landed normal on runway 28. During rollout the aircraft continued just past taxiway charlie, it slowed and was starting a turn. ?pilot had requested a 180 degree turn to back taxi to taxiway charlie?. Aircraft was now heading east when there was a large flame on the right side of the aircraft. The aircraft continued a turn to the left and went off the right side of runway 28 and out into the field where the aircraft came to rest. Initially, the aircraft appeared undamaged with a small amount of smoke coming from the pilot?s compartment. The smoke and fire continued to grow until it consumed most of the aircraft.

The majority of the fire damage to the aircraft was contained to the forward and aft cockpit and left wing. The area within the pilot?s compartment was severely burned, as most of the aluminum, wiring, and instruments were melted. The fire damage to the left wing spread from the fuselage outward from a wind heading of 180 degrees at 8 knots.

The tubular steel fuselage was severely damaged from the intense heat. The fire burned for at least 30 plus minutes, and was fed by additional fuel as the fuel system components failed and continued to feed fuel to the fire.

As of 8-18-2016, the pilot records were unavailable. The aircraft date of manufacture is estimated to be between 1945 and 1955.
