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.

GAA15CA088

The pilot reported that during the takeoff roll, he tried to abort the takeoff because he had not removed the bolt he had placed in the yoke for a gust lock. He reported that the crosswind pushed the airplane off the right side of the runway into the grass, the airplane impacted trees, and sustained substantial damage to both wings and the empennage. The pilot reported that the accident was due to him not removing the bolt in the yoke. The pilot reported no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to remove the gust lock during the preflight inspection, resulting in a loss of control and collision with trees during takeoff.
