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 reported that, while departing from the off-airport snow-covered glacier, he was not comfortable with the acceleration of the tailwheel-ski-equipped airplane and aborted the takeoff. He then began a back taxi and allowed the airplane to make a wide radius turn. Subsequently, during the turn the airplane dropped vertically into an unseen crevasse. The airplane sustained substantial damage to both wing lift struts. The pilot reported no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot’s selection of unsuitable terrain for taxi, which resulted in the airplane encountering a crevasse.
