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.

Full Narrative

On April 23, 1994, approximately 1135 mountain daylight time, a Kitfox, N446GS, was substantially damaged when it departed the runway during takeoff roll and nosed over at Longmont, Colorado. The private pilot was not injured. Visual meteorological conditions prevailed. The accident was witnessed by a Federal Aviation Administration inspector. The pilot told the inspector he raised the aircraft's tail to lift off and lost directional control. The inspector said the winds were light and variable. The following is based on the pilot/operator report. During the takeoff roll, the airplane began to veer to the right and full left rudder input did not have any effect. The airplane departed the runway, crossed an irrigation ditch, the left main landing gear collapsed, and the airplane nosed over.
