NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The glider received substantial damage during a hard landing. The certified flight instructor (CFI), seated in the rear seat, stated that he took the front seat pilot on the flight and allowed him to land the airplane during the accident landing. The CFI stated that while over the runway, "the sink rate quickly increased dramatically to a rate too high for a normal touchdown." He stated that the front seat pilot applied full back stick and the nose came up arresting the sink rate "significantly." The tail wheel initially contacted the ground which was followed by the main wheels. The CFI stated that he noted that the dive brakes were partially extended and didn't know if they had been closed and then reopened during rollout or remained open during landing.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The low airspeed by the pilot and the inadequate supervision by the certified flight instructor.
