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 PLT RPRTD THAT BEFORE HE STARTED HIS TAKEOFF, HE COULD SEE RWY LIGHTS AT THE FAR END OF THE RWY. HE ALIGNED THE ACFT FOR TAKEOFF BY REFERENCING THE SNOW BERMS (BESIDE THE RWY) & BY SIGHTING DOWN THE RWY. THE TAKEOFF ROLL SEEMED NORMAL UNTIL HE ROTATED THE ACFT FOR LIFT-OFF. AS THE ACFT LIFTED OFF, IT STRUCK THE SNOW BERM ON THE RIGHT SIDE OF THE RWY & NOSED OVER. AN INVESTIGATION REVEALED THAT ARPT PSNL HAD PLOWED THE RIGHT BERM AT A 20 DEG ANGLE AWAY FROM CENTERLINE OF THE RWY TO A POINT WHERE IT WAS ALLOWED TO ANGLE BACK ABRUPTLY TOWARD THE RUNWAY. THE ACDNT OCCURRED WHERE THE RIGHT BERM ANGLED SHARPLY TO THE LEFT.
NTSB Probable Cause
