According to the pilot, while on final approach a crosswind blew the airplane to the right side of the extended centerline of the runway. During the landing, the airplane touched down to the right of centerline and began to drift toward the right edge of the runway. The pilot attempted to execute a go-around; however, he did not apply full right rudder with the application of engine power, and the airplane departed the left side of the runway. The airplane struck a ditch, the right main landing gear sheared off, and the right wing and fuselage were substantially damaged.
