Analysis

The commercial pilot was landing on a gravel road. During landing roll, he saw tall vegetation and attempted a go around. The right spray boom contacted the vegetation at lift off and the boom was stripped off the wing. The pilot said he was in flight, full power, with no control of the ailerons. The plane made an uncommanded left bank to 45 degrees, at which point the pilot reduced power and the plane struck the terrain left wing first. The plane cartwheeled and tore the engine, cowling and nose framework from the fuselage. The plane came to rest facing opposite of the flight path.
