NTSB narrative

THE INSTRUCTOR REPORTED THAT HE PULLED THE MIXTURE TO IDLE CUT OFF TO SIMULATE AN ENGINE FAILURE FOR THE STUDENT. WHEN HE TRIED TO RESTART THE ENGINE, THE STARTER WOULD NOT TURN THE PROPELLER. A FORCED LANDING WAS MADE IN A RICE PADDY AND THE AIRPLANE NOSED OVER. THE STARTER WAS SUBSEQUENTLY TESTED AND FOUND TO DEVELOP 50% OF ITS DESIGNED CRANKING POWER. IT ALSO MADE GRINDING NOISES. INSPECTION OF THE STARTER REVEALED THAT IT HAD 24 VOLT BRUSHES INSTEAD OF THE REQUIRED 12 VOLT BRUSHES. FURTHER INSPECTION REVEALED THAT THE STARTER WAS NOT LUBRICATED, HAD A DRY BENDIX COUPLING, AND WAS CRACKED AT THE REAR BEARING HOUSING. COMPLETE REVIEW OF THE AIRPLANE'S MAINTENANCE RECORDS REVEALED NO HISTORICAL INFORMATION ON THE STARTER REGARDING DATE OF MANUFACTURE, OVERHAUL, OR INSTALLATION ON THE ENGINE.

Probable cause

THE FAILURE OF THE STARTER TO TURN THE ENGINE OVER DUE TO INADEQUATE MAINTENANCE AND INSPECTION.

  • 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: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1993-10-28.
  • API snapshot SHA-256: b975cbb3fa09897e0ecf72a83f5e0908dbfdfe602409ff988b1e53733d7dd5f7; retrieved 2026-09-23T01:30:34.814Z.
