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
WPR25LA287
The non-certificated pilot reported that, during his first flight in the recently purchased airplane, he encountered turbulence on the base and final legs of the airport traffic pattern. While on the final approach to land, the airplane encountered a gust of wind that resulted in a hard landing. The airplane sustained substantial damage to the lower fuselage and lift struts. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot reported that at the time of the accident he was landing on runway 36 with wind variable at 5 knots, gusting to 10 knots.
NTSB Probable Cause
The non-certificated pilot's improper landing flare in turbulent wind conditions, which resulted in a hard landing.
