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.

According to the pilot, he was practicing takeoffs and landings on a grass airstrip. He said snow had been removed from the center of the grass airstrip, but not the surrounding area. During his approach to land, bright sunlight reflected off the snow that made him lose his depth perception. The airplane touched down short of the runway, nosing over in deep snow. The pilot reported no preimpact mechanical problems with the airplane. The airplane received substantial damage to both wings.

NTSB Probable Cause

The pilot's misjudged altitude while landing in bright sunlight on an airstrip surrounded by snow, resulting in an undershoot and a nose over.
