The NTSB's narrative final · quoted from the NTSB record

The commercial certificated pilot was landing at a remote airstrip. When the airplane touched down, the right main landing gear strut collapsed. The propeller struck the ground, and the leading edge of the right wing struck a large rock. The pilot activated the airplane's emergency locator transmitter, and a search and rescue helicopter picked up the pilot. A postaccident examination of the airplane revealed extensive corrosion of the landing gear strut.
