He added that he applied full left aileron and full back pressure on the control yoke. The airplane then nosed over to the right and stopped. The airplane sustained substantial damage to the fuselage. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. An automated weather observation station at the airport reported, about the time of the accident, wind from 100° at 7 knots. The airplane landed on runway 11. ## Factual narrative The pilot of the tailwheel-equipped airplane reported that during the landing roll, the left wing started to lift, followed by the tail.
