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 was landing the tailwheel equipped airplane in a crosswind on runway 20 and reported that during the landing roll, "...a sudden gust from the west lifted the right wing and landing gear." As the pilot attempted to correct the situation, the airplane's left main landing gear strut collapsed, and the left wing struck the runway surface. The airplane received structural damage to left wing and fuselage. The wind at the time of the accident was from 110 degrees at 10 knots. No mechanical malfunctions were reported.

NTSB Probable Cause

The pilot's inadequate compensation for wind conditions during landing. A gusting crosswind was a contributing factor.
