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.

The pilot of a tailwheel equipped airplane reported he was attempting to depart from a remote 600ft-long airstrip. The pilot said just after the airplane lifted off the ground, it encountered windshear and did not gain sufficient altitude to clear rising terrain at the end of the airstrip. The airplane’s tailwheel impacted terrain, and the airplane veered to the left. Subsequently, the airplane impacted terrain again and came to rest upright. The right wing and fuselage sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause

Failure to maintain clearance from terrain due to the airplane’s encounter with windshear during takeoff.
