Analysis

The plt stated that shortly after takeoff when the aircraft was 25 feet in the air a downdraft was encountered near a small hill at the end of the runway. The descent caused by the downdraft could not be arrested and the aircraft collided with the ground. The aircraft was being operated 400 pounds below maximum takeoff weight and density altitude was approximately 3800 feet. Wind was reported to be out of the west at 5 to 7 knots, a head wind, according to the plt. The plt did not have knowledge of max gross wt of the acc acft (3900#) he said it was 4400#,which is correct for another ag acft, which the plt had used on occasion.
