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 was departing uphill from a remote off-airport site. The rough and gravel-covered site was about 600 feet long, with soft vegetation, and 25- to 30-foot-tall trees about 150 feet beyond the departure end. The wind was variable with moderate gusts. When the pilot realized that he did not have enough airspeed or remaining runway to clear the trees at the departure end of the site, he aborted the takeoff. The airplane subsequently overran the southeast end of the site, into an area of tree-covered, rough and uneven terrain, sustaining substantial damage to the fuselage, wings, and empennage. The pilot reported that there were no mechanical anomalies with the airplane prior to the accident that would have precluded normal operation.

NTSB Probable Cause

The pilot's selection of unsuitable terrain for takeoff, resulting in an aborted takeoff and collision with terrain.

Full Narrative

The pilot was departing, uphill, from a remote off-airport site. The rough and gravel-covered site was about 600 feet long, with soft vegetation, and 25-30 foot tall trees approximately 150 feet beyond the departure end. The wind was variable with moderate gusts. When the pilot realized that he did not have enough airspeed or remaining runway to clear the obstacles at the departure end of the site, he aborted the takeoff. The airplane subsequently overran the southeast end of the site, into an area of tree-covered, rough and uneven terrain, sustaining substantial damage to the fuselage, wings, and empennage. The pilot reported that there were no mechanical problems with the airplane prior to the accident.
