Aircraft involved
Probable cause & findings
The pilot's inability to maintain a proper rate of climb during takeoff. Factors associated with the accident were the pilot's failure to dump the chemical load and the ditch which the airplane contacted.
Factual narrative
The airplane collided with terrain following a loss of control on takeoff. The pilot reported he was taking off with a full load of fuel and chemicals when the accident occurred. He stated the airplane lifted off and climbed to an altitude of about 500 feet when it began to settle to the ground. The airplane landed in a bean field and contacted a ditch. The pilot stated he did not have time to dump the chemical load prior to impacting the ground. The takeoff was being made on a 2,000 foot long, grass airstrip.
