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.

NTSB Number
CHI07CA268
The airplane sustained substantial damage during takeoff from the grass airstrip when it failed to clear the corn at the end of the airstrip. The pilot reported that he was departing on his fourth flight of the day. The airplane was loaded with 425 gallons of water and chemicals and 150 gallons of fuel. He reported that he checked the wind before takeoff and it appeared there was no wind. He reported that during his takeoff roll, "I encountered a substantial gust of wind from the rear that prevented me from keeping the airplane airborne." He also stated that, "I believe that if this engine had been producing its maximum rated horsepower, the gust of wind would not have been the deciding factor in this take off."
NTSB Probable Cause
The partial loss of engine power during the takeoff roll for undetermined reasons and the pilot's unsuccessful compensation for the tailwind conditions. Factors contributing to the accident were the tailwind and the corn crop.
