He added that he retracted the landing gear and flaps and remained in the traffic pattern. During the second landing, he extended the flaps and reduced power for a normal landing, but during the landing flare, he heard the propeller strike the runway, and the airplane skidded to a stop. The pilot reported that he "simply forgot to check if the [landing] gear was down on the second landing attempt." The fuselage sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that during his first approach to land, he performed a go-around due to excess speed on final approach.
