Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

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.
NTSB Probable Cause
TOTAL LOSS OF ENGINE POWER DUE TO OIL EXHAUSTION FOR UNDETERMINED REASONS. THIS CAUSED THE PISTONS TO SEIZE IN THE CYLINDERS.
