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 of a tail wheel equipped airplane reported that due to carburetor icing he was forced to land on a mountain ridge. After clearing snow and sagebrush to make a runway, the pilot attempted to depart, but during the takeoff roll the airplane veered right into deep snow and sagebrush. The airplane nosed over and came to rest inverted, which resulted in substantial damage to the wing struts, rudder and vertical stabilizer. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to maintain directional control during takeoff, which resulted in an impact with deep snow and vegetation.
