At the end of a spray run, the airplane collided with trees, located in a densely wooded area, adjacent to the field being treated. According to the pilot's partner, the swath run was flown with a tailwind of about eight knots. The treated field was about 1/2 to 3/4 of a mile in length. The aircraft manufacturer noted that in turbinr powered the airplane, spray runs were typically conducted at speeds of about 150 to 170 knots.
Probable Cause: the pilot's misjudgment of his ground speed and distance to trees during the swath run, and his delayed pull-up at the end of the swath run, which resulted in his failure to remain clear of the trees. The tail wind and location of the trees were related factors.
