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.

SEA07CA219

The pilot reported that he initiated the takeoff roll on runway 24, with the wind estimated to be from 315 degrees at 8-10 knots. After sufficient acceleration, the pilot moved the yoke forward in order to raise the tailwheel off the ground. As the tail began to rise, the aircraft immediately became airborne and "aggressively drifted" to the left. The pilot was unable to correct for the deviation, and flew towards the south, away from the runway heading. The aircraft then flew over a 10 foot deep depression in the ground and descended. At the end of the depression, where the terrain rose back up to ground level, the aircraft impacted a barbed wire fence. The pilot was able to set the aircraft down in a small clearing past the fence, but due to a sloped area ahead, the pilot intentionally ground looped the aircraft to the right. The aircraft nosed over, coming to rest inverted.

NTSB Probable Cause

The pilot's failure to maintain directional control during takeoff. The crosswind condition was a factor.
