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 ACFT EXPERIENCED A TOTAL POWER LOSS ON TAKEOFF & WAS DEMOLISHED IN THE IMPACT SEQUENCE & POST CRASH FIRE. ACCORDING TO SEVERAL INTERVIEWEES THE PILOT HAD PERFORMED EXTENSIVE NON-STC'D MODIFICATIONS TO THE ACFT INCLUDING THE FUEL SYSTEM.AN 'AUTOMOTIVE PERFORMANCE COMPUTER' REQUIRING A FUEL FLOW TRANSDUCER WHICH, ACCORDING TO THE MANUFACTURER, WOULD NOT WORK ON A GRAVITY FED SYSTEM. A FUEL PUMP FOUND IN THE WRECKAGE WAS DETERMINED TO BE A FUEL TRANSFER DUMP DESIGNED TO REDUCE THE OUTPUT FLOW TO ZERO AT ITS MAXIMUM OUTPUT LINE PRESSURE OF 4.5 PSI. THE TRANSDUCER WOULD HAVE REDUCED THE FUEL OUTPUT FLOW TO A 'TRICKLE'.
