The pilot said that he was landing with a load of herbicide. During the landing roll, the airplane started to veer to the left. The pilot said he applied right rudder and right brake, but the airplane did not respond. The airplane ground looped to the left, and the right main landing gear separated from the airplane. He said all four wings appeared wrinkled, but the lower right wing was bent up. Postaccident investigation of the right brake revealed that its master brake cylinder had failed.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the failure of the right main landing wheel master brake cylinder and the subsequent inadvertent ground loop during the landing roll by the pilot. Full narrative available
