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 REPORTED THAT DURING TAKEOFF, THE ENGINE LOST POWER AT ABOUT 75 FT AGL. WHILE MAKING A FORCED LANDING, THE AIRCRAFT STRUCK LARGE PIPES THAT WERE LAYING ON THE GROUND. AN INVESTIGATION REVEALED THE ENGINE WOULD RUN SATISFACTORLY AS LONG AS THE ELECTRIC BOOST PUMP WAS ON. WHEN THE BOOST PUMP WAS TURNED OFF, THE ENGINE WOULD CEASE TO OPERATE. THE ENGINE DRIVEN FUEL PUMP (TITAN, MODEL G6, SN: 575587W) WOULD NOT PROVIDE SUFFICIENT FUEL PRESSURE TO SUSTAIN ENGINE OPERATION. AN EXAMINATION REVEALED THE SEALS AND BEARINGS WERE WORN. NO RECORDS OR HISTORY OF THE PUMP COULD BE FOUND.
