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 said that he was departing in his airplane from the downhill-sloping (east) runway at 9AK with a slight tailwind. He said that, as the airplane tried to become airborne, the tailwind increased considerably, and the airplane would not climb. The airplane struck brush that encroached the east end of the runway area and veered left into brush and small trees. He stated that no mechanical failures or malfunctions of the airplane precluded normal operation. Damage included the separation of the right outboard elevator. Photographs of the airstrip provided by the pilot showed that 9AK was a short, narrow, rough-surfaced airstrip with brush growth encroachment.
NTSB Probable Cause
The airplane's encounter with a tailwind during takeoff from a short, narrow airstrip, which resulted in a loss of lift and collision with brush and small trees.
