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 during the takeoff, the tail wheel lifted off, but the airplane would not climb out of ground effect. He stated that he used all of the runway length, and did not reduce power in time to abort the takeoff. The airplane departed the runway surface into rough terrain, which resulted in substantial damage to the rudder, horizontal stabilizer, and both elevators. The pilot stated that there were no preimpact mechanical malfunctions or failures with the airplane or engine that would have precluded normal operation. He indicated that he was based at a sea level airport, and did not take into account the high density altitude (8,600 feet), which affected the airplane’s performance.
NTSB Probable Cause
The pilot’s delayed decision to abort the takeoff. Contributing to the accident was the pilot's inadequate preflight planning and a high density altitude, which resulted in a runway excursion and collision with terrain.
