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 the airplane accelerated normally on the takeoff roll. It became airborne between 1,000 and 1,200 feet down the 2,500-foot runway, had a positive rate of climb, but was not climbing as he would have expected. The pilot elected to abort the takeoff and reduced power but then realized that he did not have enough runway remaining to land. As the pilot was adding power to abort the landing the airplane contacted the ground, departed the runway, and came to rest about 1/4 mile beyond the end of the runway after colliding with a log. The airplane sustained substantial damage to the right wing. The pilot stated that he felt the optical illusion of rising terrain and a rising runway caused him to feel that the airplane was not climbing adequately.
NTSB Probable Cause
The pilot elected to abort the takeoff without sufficient runway available to land and stop the airplane. Contributing to the accident was the illusion created by the rising terrain, which influenced the pilot's decision to abort the takeoff.
Full Narrative
The pilot reported that the airplane accelerated normally on the takeoff roll, became airborne between 1,000 and 1,200 feet down the 2,500-foot runway, had a positive rate of climb, but wasn’t climbing as he would have expected. The pilot elected to abort the takeoff and reduced power, but then realized that he did not have enough runway remaining to land. As the pilot was adding power to abort the landing the airplane contacted the ground, departed the runway and came to rest about one-quarter mile beyond the end of the runway after colliding with a log. The pilot stated that he felt the optical illusion of rising terrain and a rising runway caused him to feel that the airplane was not climbing adequately.
