On July 3, 1994, at 0600 central daylight time, an Airtractor AT-301, N3659D, collided with trees during takeoff from a private, sod airstrip near Autaugaville, Alabama. The aerial application flight operated under 14 CFR Part 137 with no flight plan filed. Visual weather conditions prevailed at the time of the accident. The airplane sustained substantial damage, and the pilot was not injured. The accident occurred during the initial takeoff of the day. According to the pilot, with a full load of chemicals, and tall grass on the takeoff surface, the airplane would not accelerate sufficiently to accomplish a safe takeoff. He lowered additional flaps, to no effect. As the runway end approached, he dumped the chemical load, and the aircraft lifted off. As he closed the dump gate, the aircraft settled again, and collided with some small pine trees, located 250 feet beyond the runway end. His safety recommendation after the accident was to cut the grass, because it was too high at the end of the strip. He reported no aircraft mechanical failure or malfunction, after the accident.
