He added that, once the airplane settled back onto the runway, he applied brakes and the airplane nosed over. The airplane sustained substantial damage to the fuselage and right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. An automated weather observation station at the accident airport recorded that, about 12 minutes after the accident, the wind was from 210° at 4 knots. The airplane landed on runway 11. ## Factual narrative The pilot of a tailwheel-equipped airplane reported that during the landing roll the right wing lifted about 4-5 ft. and the airplane "pivoted on the left landing gear".
