Analysis

The plt reported that between swath runs, his attention was directed to swath marks on the ground, then he tried to determine how much chemical was remaining in the hopper. At about 100 ft AGL, while in a 50 deg left bank, he heard 'the eng slow down' & felt 'the airplane shake as trying to stall.' He then lowered the nose & leveled the wings, but the acft impacted the ground & the main gear collapsed. The plane then slid to a stop with damage to the prop & left wing. The plt did not report any mechanical failure or malfunction.
