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.

NTSB Probable Cause
THE PILOT DELAYED REMEDIAL ACTION WHEN THE IMMINENT LOSS OF ELECTRICAL POWER WAS OBSERVED. ADDITIONALLY, THE PILOT'S FAILURE TO EXECUTE THE APPROPRIATE EMERGENCY PROCEDURE AND MANUALLY LOWER THE LANDING GEAR, RESULTED IN ITS COLLAPSE UPON LANDING. CONTRIBUTING TO THE ACCIDENT WAS THE PILOT'S LACK OF KNOWLEDGE REGARDING THE POWER SOURCE FOR THE AIRPLANE INSTRUMENTATION. WHEN CONFRONTED WITH THE ZERO OIL PRESSURE INDICATION THE PILOT'S SELF INDUCED PRESSURE PRECIPITATED AN UNNECESSARY HURRIED LANDING.
