Probable cause
The separation of the right main landing gear during takeoff, due to fatigue.
NTSB analysis
During the takeoff roll of the aerial application flight, the right main landing gear separated from the airplane's fuselage. The pilot continued the takeoff from the dirt airstrip, and elected to land at a local airport. During the landing roll, the airplane departed the runway sustaining substantial damage to the lower left wing. Examination of the right main landing gear spring leg revealed that the outboard segment had separated from the airplane at its root, adjacent to the airframe support structure. The fracture surfaces indicated a fatigue failure emanating from an area of corrosion on the lower surface of the spring.
