NTSB narrative

THE CERTIFICATED AIRLINE PILOT AND A PASSENGER DEPARTED IN A SURPLUS MILITARY COMBAT AIRCRAFT FOR A LOCAL AREA FLIGHT. ABOUT 300 FEET ABOVE THE GROUND, THE ENGINE LOST POWER. THE PILOT EXECUTED AN EMERGENCY LANDING IN AN OPEN FIELD WITH THE LANDING GEAR RETRACTED. DURING THE LANDING, ONE PROPELLER BLADE SEPARATED FROM THE ENGINE AND STRUCK THE RIGHT WING, DAMAGING THE WING SPAR. THE OCCUPANTS WERE NOT INJURED. A POST ACCIDENT EXAMINATION OF THE ENGINE FOUND NO MECHANICAL FAILURE. DURING REPAIR OF THE WINGS, THE MILITARY STYLE SELF-SEALING FUEL BLADDERS SELF-SEAL LINING WERE FOUND DETERIORATED AND THE FUEL SCREENS WERE PARTIALLY BLOCKED BY THE FUEL CELL MATERIAL.

Probable cause

AN INADEQUATE ANNUAL INSPECTION PERFORMED BY THE MECHANIC. CONTRIBUTING TO THIS ACCIDENT WAS THE DETERIORATION OF THE FUEL BLADDER SELF-SEALING LINING AND PARTIAL BLOCKAGE OF THE FUEL SCREENS.

  • 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.
