Aircraft Accident/Incident Report

Cooksville, Illinois 61730
Sunday, August 12, 2007 15:30 CDT

NTSB Narrative Summary Released at Completion of Accident

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 Narrative

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.
