Narrative:
The agricultural aircraft's certificated gross weight was 5,000 pounds. The pilot reported departing at 5,895 pounds. The temperature was 84 degrees F. with light and variable winds, and the pilot reported that the crash was a result of high density altitude. The pilot departed from a 2,485-foot asphalt runway to the west. He stated that 'Upon reaching the end of the runway, I proceeded to pull up. The a/c [aircraft] went into a 3pt attitude. I began to dump my load. The a/c flew in an uncontrolled manner for 100 yds then the right wing struck a gravel road sending me sideways into a cornfield for 300 ft then the a/c came to a stop.'

Probable Cause: The pilot's failure to maintain flying airspeed resulting in a stall/mush condition during the initial climb. Contributing factors were the high density altitude, high aircraft weight, and pilot's delayed jettison of the load, as well as the roadway and crop.
