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 WAS UNABLE TO RESTART THE ENGINE AND EXECUTED A FORCED LANDING ON SNOW COVERED TERRAIN DURING WHICH THE AIRCRAFT NOSED OVER. THE AIRCRAFT HAD SUSTAINED A SIMILAR POWER LOSS ON THE PREVIOUS DAY'S FLIGHT AND THE ENGINE DRIVEN PULSE TYPE FUEL PUMP HAD BEEN REPLACED 147 HOURS PREVIOUS IN ANOTHER POWER LOSS OCCURRENCE. THE PILOT REPORTED THAT INSUFFICIENT FUEL PUMP PRESSURE RESULTED IN FUEL STARVATION AND THE SUBSEQUENT POWER LOSS.
NTSB Probable Cause
THE FUEL PUMP DELIVERING TOO LOW FUEL PRESSURE. A FACTOR CONTRIBUTING TO THE ACCIDENT WAS THE SNOW COVERED TERRAIN.
