Probable cause & findings

THE LOSS OF ENGINE POWER BROUGHT ON BY A FAILURE OF THE NUMBER THREE CLYINDER EXHAUST VALVE. CONTRIBUTING TO THE ACCIDENT WAS A HIDDEN OBJECT ON THE EMERGENCY LANDING FIELD.

Factual narrative

THE PILOT WAS AT CRUISE ALTITUDE WHEN HE EXPERIENCED A PARTIAL LOSS OF POWER. HE TRIED TO ANALYZE HIS PROBLEM WITH NO SUCCESS. HE THEN EXPERIENCED A FURTHER POWER LOSS AND ELECTED TO DIVERT TO A NEARBY AIRPORT. THE ENGINE COULD NOT PRODUCE ENOUGH POWER TO MAINTIAN ALTITUDE SO THE PILOT FOUND IT NECESSARY TO MAKE A FORCED LANDING IN AN OPEN FIELD. AFTER TOUCHDOWN, THE AIRCRAFT STRUCK A HIDDEN OBSTRUCTION WHICH TORE AWAY THE LEFT AND NOSE LANDING GEAR. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
