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.

FLIGHT EXPERIENCED ENGINE FAILURE SHORTLY AFTER SWITCHING TO THE CHEMICAL HOPPER WHICH HAD BEEN CONVERTED TO A FUEL TANK FOR THE FERRY FLIGHT. THE ENGINE COULD NOT BE RESTARTED AND A FORCED LANDING WAS MADE IN A WOODED AREA. POST CRASH OPERATION OF THE ENGINE REVEALED THE ENGINE WOULD NOT RUN ON THE ENGINE DRIVEN FUEL PUMP.

THE ENGINE DRIVEN PUMP WAS FOUND TO CONTAIN BLACK RUBBER PARTICLE CONTAMINATION UNDER THE BYPASS VALVE AND TO BE WORN WHICH PREVENTED PRESSURE BUILD UP. THE HOPPER TANK LINE ENTERED THE AIRFRAME FUEL SYSTEM AFTER THE ELECTRIC BOOST PUMP AND THE ONLY SOURCE OF HOPPER TANK FUEL PRESSURE WAS THE ENGINE DRIVEN PUMP.

NTSB Probable Cause

THE INADEQUATE INSPECTION FOR CONTAMINATION OF THE AIRCRAFT FUEL SYSTEM AFTER MODIFICATION RESULTING IN FAILURE OF THE ENGINE DRIVEN FUEL PUMP DUE TO CONTAMINATION.
