On July 5, 1995, at 1330 Alaska daylight time, a wheel equipped Piper PA-20 airplane, N6946K, registered to and operated by the pilot, nosed over during the landing roll on a ridge in the Caribou Hills, north of Homer, Alaska. The personal flight, operating under 14 CFR Part 91, departed Kenai, Alaska, and the destination was the ridge line on which the airplane crashed. Visual meteorological conditions prevailed and a visual flight rules flight plan was filed. The private certificated pilot and his passenger were not injured and the airplane received substantial damage. According to the pilot, the ridgeline on which he landed is at the 2000 foot level in the Caribou Hills and is 1100 feet long with a lengthwise crown. He landed the airplane in the first 100 feet of the ridge and when the airplane crested the crown he began braking. The airplane slowed down and the tail began to come up. The propeller struck the ground and the airplane continued to slowly nose over.
