Investigator assessment
Analysis narrative
The instructor pilot said the airplane touched down 3 to 5 degrees nose right of the runway centerline, and he told the instructor trainee to apply left rudder. The rudder pedal did not move. The instructor pilot also applied left rudder and got the same result. As the airplane started to go off the side of the runway, the instructor pilot applied full power. The airplane became airborne for approximately 1,000 ft, then began to stall and roll. To avoid striking the ground in a banked attitude, the instructor pilot retarded the throttles and levelled the wings. The right wing struck the airport's segmented circle, spun to the right, and skidded to a halt. Post accident examination of the rudder control system did not disclose any malfunction or failure.
