Incident Overview
A pilot reported a landing accident on a volcanic cinder area approximately 1,000 feet in length. The pilot described visibility as unlimited, winds at five knots, and light rain on the windshield during the approach. While in the landing flare, the left main landing gear contacted a tundra hummock two feet in height. Upon touchdown, the left landing gear leg collapsed. The left elevator and left aileron sustained substantial damage.
