He added that he subsequently "applied power," but as he did so, the right main landing gear collapsed as the airplane ground looped counter-clockwise on the runway. The right wing sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. An automated weather observation station at the accident airport reported that, about the time of the accident, the wind was from 090° at 5 knots. The pilot reported that the landing was on runway 15. ## Factual narrative The pilot of the tailwheel equipped airplane reported that, during the three-point touchdown the airplane "immediately veered left" and he applied full right rudder.
