What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Powerplant quit on roll out and the aircraft was stopped. Pilot was attempting a restart when he noticed smoke coming from the right side of the engine cowling. He exited the aircraft to investigate and discovered flames coming out of the cowling. The fire spread to the cockpit and the pilot only had time to retrieve logs and personl items in the front seat. Pilot was unsure of the position of the fuel boost pump after landing. Ignition source is unknown. Fire originated from the air filter container. Engine rotated okay by hand. It appears that the engine quit with the boost pump on and the boost pump continued to feed fuel to the fire spreading to the cabin through the cabin heat system.
