NTSB narrative

AFTER APPROXIMATELY ONE HOUR AND FIFTEEN MINUTES INTO A CROSS COUNTRY FLIGHT THE PILOT OBSERVED THE ENGINE OIL PRESSURE DECREASING. HE ELECTED TO MAKE A PRECAUTIONARY LANDING ON A HIGHWAY. WHEN THE AIRCRAFT TURNED ONTO THE FINAL APPROACH THE ENGINE LOST POWER AND THE AIRCRAFT'S RIGHT WING COLLIDED WITH A TREE. THE AIRCRAFT THEN STRUCK THE ROAD IN A NOSE-DOWN ATTITUDE, COLLAPSING THE NOSE AND LEFT MAIN LANDING GEARS. EXAMINATION OF THE ENGINE FAILED TO DISCLOSE ANY PREEXISTING MALFUNCTIONS OR FAILURES.

Probable cause

THE LOSS OF ENGINE POWER FOR UNDETERMINED REASONS AND THE LACK OF SUITABLE TERRAIN FOR A FORCED LANDING.

  • 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 1992-07-11.
  • API snapshot SHA-256: d48377195452c53ae8d80cd2c09bc18f7e003ac8117c710ffb693edf19de390c; retrieved 2026-09-21T23:12:47.225Z.
