"THIS CASE WAS MODIFIED MARCH 25, 2009."
The airplane was departing on an aerial application sortie when the lower portion of the rudder separated and yaw control was lost. The pilot flew the airplane for approximately 1/2 hour to learn its flight characteristics at low airspeeds and low power settings. During the landing, the airplane turned sideways, nosed over, and came to rest inverted. Examination of the rudder revealed that the lower rudder attachment point had failed. The separation surfaces displayed evidence of severe corrosion. The airplane had an annual inspection on March 17, 2008, and had flown 1/2 hour since the inspection. The area where the corrosion was found and the failure occurred did not require inspection.
Probable Cause: The in-flight failure of the rudder attachment point due to severe corrosion, which made directional control of the airplane not possible during landing.
