Probable cause & findings
THE LOSS OF POWER DUE TO ENGINE FAILURE, FOR UNDETERMINED REASONS.
Factual narrative
THE WW2 VINTAGE FIGHTER ACFT WAS IN A FLT OF 4 ACFT WHEN THE ENGINE BEGAN RUNNING ROUGH, LOST OIL PRESSURE AND FAILED. THE PILOT PARACHUTED FROM THE ACFT, WHICH CAUGHT FIRE BEFORE HE COULD REACH THE NEAREST ARPT FOR AN EMERGENCY LDG. THE ACFT IMPACTED TREES AND STARTED A FOREST FIRE. THE ENGINE WAS DESTROYED BY FIRE.
