What happened
The aircraft was observed departing from runway 35 of a private agricultural strip measuring 4,250 feet in length. The plane had been loaded to near its capacity limit with 46 percent nitrogen fertilizer. During the takeoff roll, data indicated the presence of an 11-knot tailwind on the grass surface, which increased the required takeoff distance by approximately 65 percent, or roughly 1,000 feet, bringing the total needed to about 2,235 feet.
After lifting off, the pilot initiated fuel dumping at mid-field. The aircraft crossed a fence running parallel to the runway but subsequently struck a second fence positioned perpendicular to the north end of the runway. Following this impact, the aircraft settled onto the ground in an adjacent pasture. Its right wing struck and rode up over a land plane before the aircraft hit a series of rice harrows supported by barrels. The force of these impacts caused the aircraft to flip over and slide to a stop in an inverted position.
The pilot sustained serious head and neck injuries during the accident sequence.
