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.

After the pilot applied full engine power for takeoff, the airplane veered to the left. The pilot attempted to apply right rudder, but was unsuccessful in regaining control of the airplane before it departed the runway surface. The airplane bounced several times as it continued across the grassy area adjacent to the runway and a taxiway before it came to a stop. During the accident sequence the firewall was substantially damaged. Examination of the airplane's rudder and nosewheel steering system revealed no evidence of any preimpact mechanical malfunctions or failures that would have precluded normal operation.
NTSB Probable Cause
The pilot's loss of directional control during the takeoff, and her delayed remedial action in aborting the takeoff after the loss of directional control.
Full Narrative
The pilot taxied the airplane onto the runway and applied full power to the engine for takeoff. The airplane veered to the left, and the pilot attempted to apply right rudder, but was unsuccessful in regaining control of the airplane before it departed the runway surface. The airplane bounced several times as it crossed the grassy area adjacent to the runway and a taxiway, before the pilot cut off the engine. The airplane ultimately came to rest about 2,000 feet from the runway threshold. During the accident sequence the nose landing gear collapsed and the firewall was substantially damaged. Examination of the airplane's rudder and nosewheel steering system revealed no evidence of any pre-impact mechanical malfunctions or failures.
