On July 20, 2001, about 2045 Mountain daylight time, a tailwheel-equipped Cessna 150, N10RH, sustained substantial damage subsequent to a nose over while landing at McCarley Field, Blackfoot, Idaho. The airplane is owned by the pilot, and was being operated as a personal cross-country flight under the provisions of Title 14, CFR part 91, when the accident occurred. Visual meteorological conditions prevailed, and no flight plan had been filed. The private pilot, and the one passenger aboard the aircraft, were not injured. The pilot submitted a written statement to the National Transportation Safety Board dated July 29. He reported that shortly after touchdown (wheel landing) on runway 19, the airplane "… started turning to the left." He stated that he applied right rudder without response and then applied brakes. Shortly after applying brakes, the airplane swerved to the right and nosed over.
