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 FINAL APCH THE ENG QUIT. THE PLT THEN ATTEMPTED TO LAND THE ACFT ON A ROAD, DURING WHICH, IT COLLIDED WITH TREES. INSPECTION OF THE ACFT REVEALED THAT THE ADJUSTING SCREW ON THE ENG DRIVEN FUEL PUMP BACKED OUT APRX 8 TURNS. BENCH TEST OF THE PUMP REVEALED THAT THE FUEL FLOW FROM THE OUTLET WAS HIGHER THAN THE LIMITS SPECIFIED BY THE MANUFACTURER DUE TO THE COUNTER-CLOCKWISE ROTATION OF THE SCREW. ACCORDING TO A FAA INSPECTOR THE ENGINE COULD POSSIBLY QUIT IF THE MIXTURE CONTROL WERE PLACED IN THE FULL RICH POSITION AS IS THE CASE DURING APCH, DUE TO EXCESSIVE FUEL.
