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.

CEN09CA548

The pilot reported that he began the takeoff roll in the tailwheel-equipped airplane with a left quartering headwind. He stated that during the takeoff roll a wind gust caused the airplane to swerve. He attempted to abort the takeoff and the airplane ground-looped. During the event, the right main landing gear collapsed and the wing tip struck the runway, damaging the wing structure. A weather reporting station located 18 nautical miles south of the accident site recorded the wind 7 minutes before the accident as being from 190 degrees at 11 knots, gusting to 18 knots. Fifty-three minutes after the accident time the same weather station recorded the wind speed as 7 knots gusting to 14 knots and direction as variable between 130 degrees and 200 degrees. Examination of the airplane after the accident revealed a failure of the left steering spring chain link. It could not be determined if the chain link failure occurred prior to or during the accident sequence.
