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
WPR12CA273
The pilot was performing a landing in gusting crosswind conditions in the tailwheel-equipped airplane. During the landing flare, a wind gust lifted the airplane’s right wing. The pilot applied corrective control input and then landed. After he parked the airplane, the pilot realized that the airplane’s left wing had contacted the runway during the landing flare, causing substantial damage to the aileron and outboard wing skins. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation.
