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.

DRG FLT AT 10,500' MSL, THE ENG LOST POWER & WOULD NOT RESTART. THE PLT MADE A FORCED LANDING ON RWY 21 AT A NEARBY ARPT. THE RWY WAS ONLY 3800' LONG & HAD A RPRTD DOWNWARD SLOPE OF 1.5 DEG. THE WIND WAS ESTIMATED TO BE FROM 270 DEG AT 10 KTS. THE PLT RPRTD THAT DRG THE LANDING, THE ACFT TOUCHED DOWN AT ABOUT MIDFIELD & HE WAS UNABLE TO STOP ON THE REMAINING RWY. AFTER GOING OFF THE DEPARTURE END, IT HIT A FENCE & WAS DAMAGED. A POST ACDNT EXAM REVEALED THERE WAS SEVEN GAL OF FUEL REMAINING. A CHECK OF THE FUEL SYSTEM REVEALED EVIDENCE THAT THE MAIN FUEL LINE & FUEL FILTER WERE RESTRICTING FUEL FLOW. THE PLT RELATED THAT THIS ACFT HAD A SIMILAR PROBLEM PREVIOUSLY & HE HAD DRAINED A CONSIDERABLE AMOUNT OF WATER FROM THE FUEL SYSTEM. AUTOMOTIVE FUEL WAS BEING USED IN THE ACFT.
NTSB Probable Cause
INADEQUATE SERVICING OF THE AIRCRAFT BY THE PILOT, PARTIAL BLOCKAGE OF THE FUEL LINE AND FUEL FILTER, AND FUEL STARVATION. CONTRIBUTING FACTORS WERE: THE DOWNWARD SLOPING RUNWAY AND A FENCE.
