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.

A single engine aerial application aircraft modified as a fire tanker veered off the gravel runway during its landing roll and sustained substantial damage to the right wing. The pilot said he was traveling about 40 mph with the tail on the ground during the landing roll and was unable to maintain directional control due to adverse wind conditions. The airplane veered off the left side of the runway despite the pilot's application of full right rudder and right brake, and encountered uneven terrain and high vegetation. The pilot stated that the airplane and engine had no mechanical failures or malfunctions.
NTSB Probable Cause
the pilot's inadequate compensation for the wind conditions and failure to maintain directional control during the landing roll.
