Aircraft flight hours:

Circumstances:
The aircraft was engaged in a local spraying mission, carrying a crew of three and a load of 3,666 gallons of insecticides. After takeoff from runway 23, while in initial climb, the airplane entered a flat attitude then descended until it struck trees and crashed in flames about 3 km southwest of the airport. The aircraft was totally destroyed by a post crash fire and all three crew members were killed.
Probable cause:
Investigations determined that the flaps were retracted at the time of the accident while the aircraft was flying at a relative low speed during initial climb. It is believed that this was likely a result of a premature retraction of the flaps on part of the flying crew below the minimum altitude of 500 feet, resulting in a loss of altitude.
