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 Number
GAA17CA187
The pilot of the tailwheel, ski-equipped airplane reported that, while landing off airport in flat light conditions, he was unable to maintain a good visual reference of the hard-packed snow-covered landing area. After touchdown, the airplane drifted off the hard-packed snow, and the left ski sunk in softer snow. He increased power and attempted to recover with "hard right control" to no avail. The airplane's left ski struck a snow-covered tank. The airplane sustained substantial damage to the left-wing lift strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot’s failure to maintain directional control while landing in flat light conditions on a hard-packed snow-covered landing area.
