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 he was flying at a low altitude over rising terrain during a Title 14, CFR Part 91 business flight, searching for sites to deploy a tent camp in support of a lodge operation. While approaching a ridgeline, he stated that a powerful downdraft forced the airplane into a brush-covered hillside. The pilot reported that neither he nor the sole passenger were injured, and that there were no preaccident mechanical problems with the airplane. The airplane received substantial damage to the wings and fuselage structure.
NTSB Probable Cause
The pilot's failure to maintain adequate altitude/clearance from rising terrain while maneuvering at a low altitude, which resulted in an in-flight collision with terrain. Factors associated with the accident were a downdraft, the pilot's intentional low altitude flight, and his inadequate weather evaluation.
