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. ## Factual narrative On August 6, 2005, at 1532 central daylight time, a Let Blanik L-13, N9295Z, operated by Omaha Soaring Club, received substantial damage during a hard landing on runway 13 (3,450 feet by 50 feet, asphalt) at Blair Municipal Airport, Blair, Nebraska.

Over the runway, "the sink rate quickly increased dramatically to a rate too high for a normal touchdown." He stated that the commercial pilot applied full back stick, and the nose came up arresting the sink rate "significantly." The tail wheel initially contacted the runway which was then 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 had remained open during landing. According to the Federal Aviation Administration inspector, both pilots held CFI certificate with glider ratings.
