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 on runway 34. The tail wheel touched down first and the airplane bounced on its main landing gear. The pilot "overcorrected first right, then left," and the airplane skidded "with the left wing down" and went off the left side of the runway. Postaccident examination revealed the top left wing skin was wrinkled and several ribs were damaged. The AWOS observation indicated the wind was calm.
NTSB Probable Cause
the pilot's improper recovery from a bounced landing, and his failure to maintain directional control during landing that resulted in an inadvertent ground loop/swerve.
