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 STARTED THE TAKEOFF ROLL ON THE ICY RUNWAY. HE SAID, 'AT APPROXIMATELY 70 KNOTS (AT ROTATION) THE AIRCRAFT STARTED TO DRIFT LEFT AND BOTH STEERING AND RUDDER WERE INEFFECTIVE IN STOPPING THE DRIFT. THE LEFT PROPELLER STRUCK THE ICE BANK.' THE AIRPLANE YAWED TO THE LEFT AND DEPARTED THE RUNWAY, COLLAPSING THE LANDING GEAR. THE WIND WAS APPROXIMATELY 45 DEGREES FROM THE RIGHT AT AN ESTIMATED 4 KNOTS. THE EDGES OF THE RUNWAY HAD SNOW BANKS APPROXIMATELY 2 FEET HIGH. AN EXAMINATION BY THE FAA OF THE AIRPLANE RUDDER AND BRAKING SYSTEMS FOUND NO DISCREPANCIES.
NTSB Probable Cause
THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL DURING TAKEOFF, AND HIS INADEQUATE REMEDIAL ACTIONS, RESULTING IN A COLLISION WITH A SNOWBANK. FACTORS RELATED TO THE ACCIDENT WERE THE ICE COVERED RUNWAY AND THE SNOWBANK ALONG THE RUNWAY EDGES.
