- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
- Part 91: General Aviation
- Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
- En route · climb to cruise
- First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Total loss of engine power (non-mechanical)
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
BEFORE DEPARTURE, THE PLT PREFLIGHTED THE ACFT & PERFORMED AN ENG RUN-UP WITH NO DISCREPANCIES NOTED. AFTER DEPARTURE WHILE CLIMBING THROUGH 5,500 FT, THE ENG QUIT. THE PLT RESTARTED THE ENG BUT OBSERVED THE OIL PRESSURE WAS ZERO. THE ENG QUIT AGAIN & HE WAS UNABLE TO RESTART IT. DURING THE FORCED LANDING IN A FIELD, THE ACFT COLLIDED WITH A TREE. EXAM OF THE ACFT REVEALED OIL COATING THE BOTTOM OF THE FUSELAGE. THE ENG COMPARTMENT WAS NOT CONTAMINATED. THE ENG WAS REMOVED & EXAM OF IT REVEALED THAT THE NO'S 1,2,5, & 6 PISTONS SCORED THE CYLINDER WALLS. NO'S 3 & 4 PISTONS WERE NORMAL. DUE TO THE DAMAGE, NO DIMENSIONAL ANALYSIS OF THE FAILED PISTONS & CYLINDERS COULD BE MADE. THE ENG DRIVEN OIL PUMP WAS EXAM & FOUND TO BE FREE OF FAILURE OR MALFUNCTION. NO DETERMINATION COULD BE MADE AS TO THE REASONS FOR THE LOSS OF ENG OIL RESULTING IN THE TOTAL LOSS OF ENG POWER DUE TO SEIZURE OF THE NO'S 1,2,5, & 6 PISTONS IN THE CYLINDERS. THE ACFT & ENG HAD ACCUMULATED 16.1 HRS SINCE MANUFACTURE.
Probable cause
TOTAL LOSS OF ENGINE POWER DUE TO OIL EXHAUSTION FOR UNDETERMINED REASONS. THIS CAUSED THE PISTONS TO SEIZE IN THE CYLINDERS.

- 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.
