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 commercial certificated pilot reported that he was departing a remote mountain ridge on a Title 14, CFR Part 135 cross-country air taxi flight. The takeoff area was about 500 feet long, and about 15 feet wide. The pilot said he departed downhill with a 10 mph quartering tailwind. About 250 feet from the starting point, the pilot said that the crosswind pushed the airplane to the right, and the right wing collided with a tree. The airplane veered to the right, and the left main landing gear collapsed. The airplane received structural damage to the right wing.
NTSB Probable Cause
The pilot's failure to compensate for the wind conditions during the takeoff roll, which resulted in a collision with a tree. A factor contributing to the accident was a crosswind.
