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.

WHILE CRUISING AT 3500 FEET, THE PILOT EXPERIENCED A HEAVY VIBRATION IN THE ENGINE AND WAS VECTORED TO A NEARBY AIRPORT. HE WAS HIGH AS HE TURNED ONTO FINAL APPROACH. HE RETRACTED THE WING FLAPS AND THE LANDING GEAR, AND ADDED POWER TO TRY FOR A NEARBY FIELD. THE ENGINE FAILED TO RESPOND AND HE LANDED HARD NEXT TO THE RUNWAY. WITNESS REPORTED THE AIRPLANE APPEARED TO STALL FROM A HEIGHT OF 40 TO 50 FEET. POST-CRASH EXAMINATION REVEALED THE OIL SCREEN HAD BEEN REPLACED WITH AN OIL FILTER ADAPTER WHICH HAD COME LOOSE AND THE ENGINE OIL ESCAPED THROUGH THE OPENING. THE $4 CONNECTING ROD FAILED DUE TO OIL STARVATION AND PENETRATED THE ENGINE CASE. THE THREADS ON THE OIL FILTER ADAPTER WERE WORN AS WERE THE MATING THREADS ON THE OIL PUMP HOUSING.
NTSB Probable Cause
