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.

ACFT EXPERIENCED A POWER LOSS IMMEDIATELY AFTER TAKEOFF FROM AN OFFSHORE PLATFORM IN THE GULF OF MEXICO. THE PLT HELD COLLECTIVE TO CLEAR THE RIG AND THEN POPPED THE FLOATS AND AUTOROTATED TO THE WATER. THE AUTO WAS SUCCESSFUL, HOWEVER, THE ACFT WAS STRUCK BY A 5' WAVE AND ROLLED OVER. BOTH OCCUPANTS EGRESSED WITHOUT PROBLEM AND THE PAX SWAM TO THE RIG. THE PLT INFLATED HIS LIFE VEST AND WAS SWEPT AWAY BY THE CURRENT AND SWAM ASHORE 14 HOURS LATER. INVESTIGATION REVEALED THAT THE COMPRESSOR DISCHARGE PRESSURE (PC) LINE WAS DISCONNECTED FROM THE BACK OF THE ENG FUEL CONTROL. A LEAK OR SEPARATION OF THE PC LINE WOULD CAUSE THE FUEL SCHEDULE TO REDUCE ENG SPEED TO BELOW FLT IDLE. NO RECENT MAINTENANCE HAD BEEN PERFORMED ON THE FUEL CONTROL OR THE LINE.
