Analysis
A commercial ag plt was working a field with 2-4-D and had been spraying for 15 minutes. On a turn to reverse direction at the end of a pass, the plt started a 45 degree bank pull up and added full throttle. The engine then had a partial power loss and began to lose RPM. The acft stalled and fell right wing first, 200 feet to the ground. The engine, right wing and right main gear separated and the fuselage came to rest 50 feet from the impact point. An immediate post accident fire destroyed most of the wreckage.
