NTSB narrative
THE ENGINE 'STARTED TO RUN ROUGH' AND SMOKE FILLED THE COCKPIT. DURING THE DOWNWIND APPROACH TO A FIELD, FORWARD VISIBILITY WAS LIMITED BY THE SMOKE. ON SHORT FINAL, THE PILOT OBSERVED A FENCE ACROSS THE LANDING AREA AND 'PULLED THE YOKE ALL THE WAY BACK.' FOLLOWING THE HARD LANDING, THE AIRPLANE TRAVELED THROUGH THE FENCE. THE NOSE GEAR COLLAPSED, AND THE ENGINE FUSELAGE AND WINGS WERE DAMAGED. ENGINE OIL WAS FOUND ON THE ENGINE COWLING AND IN THE AREA OF THE #4 CYLINDER. THE OIL SUMP CONTAINED APPROXIMATELY 1.5 QUARTS OF OIL. THE EXHAUST VALVE PUSH ROD AND THE PUSH ROD TUBE ON THE #4 CYLINDER WERE BENT AND WERE NO LONGER IN PLACE. ENGINE TIME SINCE THE LAST MAJOR OVERHAUL WAS 697.65 HOURS AND THE TIME SINCE THE LAST ANNUAL INSPECTION WAS 26 HOURS.
Probable cause
THE LOSS OF ENGINE POWER DUE TO A BENT PUSH ROD AND THE RESULTANT LOSS OF OIL. FACTORS WERE THE COCKPIT SMOKE AND THE LACK OF SUITABLE TERRAIN FOR THE FORCED LANDING.

Source notes (4)
- 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.
