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.

THE PILOT APPARENTLY HAD NEGLECTED TO CHECK HIS ENGINE OIL SUPPLY BEFORE TAKEOFF SINCE THERE WAS NO OIL IN THE CRANKCASE AT THE TIME OF THE ACCIDENT. IF FIVE QUARTS OF OIL (THE AMOUNT THE PILOT REPORTEDLY STATED WAS IN THE ENGINE AT TAKEOFF) HAD LEAKED OUT DURING A FIVE MINUTE FLIGHT, THEN THE BOTTOM OF THE FUSELAGE AND THE EMPENNAGE ASSEMBLY WOULD HAVE BEEN COATED WITH OIL. EXAMINATION OF THE AIRCRAFT AT THE ACCIDENT SITE SHOWED NO SIGNS OF AN OIL LEAK. THE FORCED LANDING WAS MADE ON ROUGH AND UNEVEN TERRAIN. AFTER TOUCHDOWN THE NOSE GEAR CONTACTED A DIRT BANK AND COLLAPSED.
