Departure and Configuration
The airplane was departing from a 2,400-foot asphalt runway for an aerial application flight. It was loaded to its maximum gross takeoff weight and configured with 10 degrees of flaps prior to the takeoff roll.
Pilot's Account
The pilot reported that a tall stand of trees at the southeast side of the departure end of the runway blocked the wind and seemed to “create a void in the air,” which resulted in an extended takeoff roll. Electing not to abort the takeoff, the pilot added more flaps, but the airplane was unable to get airborne.
Accident Sequence
After the extended takeoff roll, the airplane went off the end of the runway, hit a ditch, and skidded across the road into a field. The landing gear separated from the airframe, and the airplane’s fuselage and control surfaces sustained substantial damage. The pilot reported that no mechanical malfunction occurred during the attempted takeoff.
