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 reported that while performing a three-point landing on runway 18, during the roll out the airplane veered left, exited the runway to the left, and ground looped in the counter-clockwise direction. During the ground loop, the right wing struck the ground and the airplane came to rest upright on the main landing gear. The right aileron sustained substantial damage. After the accident sequence the pilot noted that the tailwheel lock was not fully in the locked position. The pilot was able to taxi the airplane to parking without further incident. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot’s failure to engage the tailwheel lock before landing which resulted in the loss of control and ground loop.
