NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The certificated flight instructor, with a pilot-rated passenger in the left seat, was landing a tailwheel-converted airplane in gusty, right crosswind conditions. During the landing roll, the instructor lost directional control, and the airplane departed the runway to the right, and went into a ditch. In a written statement to the NTSB, the instructor indicated that there was a structural failure of the tailwheel-mounting bracket that precipitated the loss of control. Three pilot-rated witnesses responded to the accident site immediately after the accident, and none of them reported seeing any significant damage to the tailwheel assembly. A certificated aviation mechanic, and an FAA airworthiness inspector examined the airplane, and stated that the damage to the tailwheel was done during the recovery process, not during the accident. The owner of the airplane related to the NTSB investigator-in-charge that the instructor stated to him that he just lost directional control during the crosswind landing.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's failure to compensate for a gusty crosswind during the landing roll, which resulted in a loss of control and an on-ground encounter with a ditch. Factors associated with the accident are a crosswind and wind gusts. Full narrative available
