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.

DURING CRUISE FLIGHT THE ACCIDENT AIRCRAFT LOST OIL PRESSURE IN THE NUMBER 2 ENGINE. FLIGHT COULD NOT BE SUSTAINED USING THE REMAINING ENGINE. ACCORDING TO THE PILOT, THE REMAINING ENGINE WOULD OVERHEAT WHEN POWER WAS APPLIED. THE CREW DESCENDED TO JUST ABOVE THE WATER AND TRIED TO FLY THE AIRCRAFT IN GROUND EFFECT, BUT TO NO AVAIL. THEY ELECTED TO DITCH THE AIRCRAFT. DURING THE LANDING, THE AIRCRAFT RECEIVED SUBSTANTIAL DAMAGE AND WAS ALMOST IMMEDIATELY FLOODED, CAUSING THE AIRCRAFT TO SINK. THE CREW ESCAPED, BUT DID NOT HAVE TIME TO RETRIEVE EMERGENCY GEAR. THEY WERE RESCUED AFTER ABOUT 20 HOURS IN THE WATER. EVIDENCE REVEALED THAT THE PILOT DID NOT HAVE A PILOT'S CERTIFICATE. NO EVIDENCE COULD BE FOUND TO INDICATE THAT THE PILOT HAD ANY EXPERIENCE IN THE ACCIDENT AIRCRAFT OR WITH ANY SEA PLANE. SINCE THE AIRCRAFT SANK, A CAUSE FOR THE ENGINE PROBLEMS COULD NOT BE DETERMINED.
NTSB Probable Cause
IMPROPER TOUCHDOWN IN THE WATER CAUSING SUBSTANTIAL DAMAGE. LOSS OF POWER ON THE NUMBER 2 ENGINE AND THE PILOT'S LACK OF QUALIFICATIONS WERE FACTORS IN THE ACCIDENT.
