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
WPR21LA176
The pilot reported that, as he approached the airport, he noted there was turbulence, and that the windsock was indicating light winds. While on the short-final leg of the traffic pattern for runway 16, the airplane encountered a downdraft. The airplane’s sink rate increased and in response, the pilot applied full engine power. Despite his attempt to arrest the descent, the airplane touched down about 200 ft before the runway in soft terrain. The airplane nosed over coming to rest inverted. Both wings were substantially damaged.
NTSB Probable Cause
The pilot’s failure to maintain airplane control while compensating for a downdraft during landing, which resulted in the airplane touching down short of the runway on soft terrain and nosing over.
