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.

Instructor and ast. Chief instructor were conducting annual proficiency check. After about 0.7 hours of flight time in the practice area, they returned to the airport for practice landings. On roll-out of the first landing, a planned stop & go, the engine quit with the aircraft on the runway about 2,000 past the threshold. The instructors tried to restart using the warm-engine procedures, and noticed white billowing smoke coming from the cowling, primarily the forward portion of the right side of the cowling. This was immediately followed by darker smoke and flames. The instructors called ATC, advising they were on fire and evacuating the aircraft. They evacuated the aircraft and proceeded away from the runway center line and awaited fire & rescue, who extinguished the fire. Subsequent investigation shows that there was a large amount of fuel in the carburetor box and lower cowling and that it was likely that the carburetor needle valve was stuck open.
