On May 17, 1998, at 1530 central daylight time, an Air Tractor AT-502B agricultural airplane, N502JF, was destroyed upon impact with a tree and terrain during takeoff near Parkin, Arkansas. The non-instrument rated commercial pilot, sole occupant of the airplane, was not injured. The airplane was owned and operated by Hutcherson Flying Service Inc., of Forrest City, Arkansas, under Title 14 CFR Part 137. Visual meteorological conditions prevailed for the aerial application flight for which a flight plan was not filed. The flight was originating from a private airstrip at the time of the accident. According to local law enforcement officers that responded to the accident site, the airplane collided with an oak tree at the departure end of the 2,300 foot airstrip while attempting to takeoff to the south with a load of "Urea" dry fertilizer. In the narrative portion of the enclosed Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2), the pilot stated that the airplane broke ground while taking off from the dirt strip; however, the airplane failed to clear a tree line 200 feet beyond the departure end of the turf runway. The pilot stated that the engine was performing normally. The pilot estimated that he had 100 gallons of fuel on board. The position of the flaps could not be determined. The NTSB investigator estimated that the density altitude at the time of the accident was 2,200 feet. The pilot's operating handbook does not provide takeoff performance data for the airplane.
