NTSB narrative

WITNESSES REPORTED THAT DURING THE TAKEOFF INITIAL CLIMB, ENGINE SOUNDS CEASED AND THE PROPELLER STOPPED IN A VERTICAL POSITION. THE AIRPLANE TOUCHED DOWN ON A GRASSY AREA BEYOND THE DEPARTURE END OF THE RUNWAY; AFTER TRAVERSING ROUGH AND UNEVEN TERRAIN, IT ENCOUNTERED A DIRT BANK AND BECAME AIRBORNE. THE AIRPLANE THEN DESCENDED INTO A 25' DEEP RAVINE. AN EXAMINATION REVEALED THE ENGINE WAS BINDING DURING ROTATION AND THE FRONT REDUCTION GEAR CASE WAS REMOVED. THE PROPELLER SHAFT THRUST BEARINGS FIT LOOSELY ABOUT THE JOURNAL, EXHIBITED SCRATCHES, AND WERE NOT THE CORRECT BEARINGS. BOTH THE PROPELLER DRIVER GEAR FRONT BEARING AND REAR BEARING WERE SOLID BRASS BEARINGS. THE MANUFACTURER PRINT SPECIFICATIONS FOR THESE BEARINGS LISTED A STEEL BACKED SPLIT BEARING. THE FRONT BEARING WAS SEIZED TO THE PROPELLER DRIVE GEAR. THE CRANKCASE AND THE FORWARD GEAR CASE EXHIBITED GALLING AND METAL DEBRIS, WHICH WAS IDENTIFIED AS ALUMINUM FROM THE MAIN GEAR CASE. THE ENGINE MAIN BEARINGS AND ROD BEARINGS EXHIBITED SCRATCHES.

Probable cause

IMPROPER MAINTENANCE OF THE ENGINE BY UNKNOWN PERSON(S), THE INSTALLATION OF UNAPPROVED PARTS, AND SUBSEQUENT BEARING SEIZURE. THE LACK OF SUITABLE TERRAIN IN THE FORCED LANDING AREA WAS A RELATED FACTOR.

  • 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.
  • API snapshot SHA-256: 1c0d22b5be35b43f91a540baacd427839e0f19ba295861befcb982773b0edcc3; retrieved 2026-09-21T00:01:01.582Z.
