Partial loss of engine power (mechanical failure)
Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
Stall/spin
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

AT CRUISE ALTITUDE THE ENGINE STARTED TO VIBRATE. DURING THE FORCE LANDING THE PILOT FELT THAT THE SPEED OF THE AIRPLANE WAS TOO FAST SO ELECTED TO GO AROUND AND ATTEMPT ANOTHER APPROACH. THE PILOT TURNED THE AIRPLANE AWAY FROM THE INTENDED LANDING SITE, AND WHILE IN THE TURN THE AIRPLANE STALLED AND SPUN INTO THE GROUND. AN EXAMINATION OF THE ENGINE REVEALED THAT THE NUMBER 3 EXHAUST VALVE FAILED DUE TO CORROSION AND EXTENSIVE INTERNAL DAMAGE WAS FOUND IN THE ENGINE.

Probable cause

THE PILOT INADVERTENTLY STALLED AND SPUN THE AIRPLANE AT TOO LOW AN ALTITUDE TO ALLOW RECOVERY. CONTRIBUTING TO THE ACCIDENT WAS AN ENGINE VIBRATION CAUSED BY A BROKEN NUMBER 3 EXHAUST VALVE. THE EXHAUST VALVE CAUSED EXTENSIVE INTERNAL DAMAGE TO THE ENGINE.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
