Aircraft Accident/Incident Report
Yellow Pine, Idaho 83677
Sunday, February 5, 2012 12:20 MST
NTSB Narrative Summary Released at Completion of Accident
During the landing at a remote snow-covered airstrip, the airplane touched down at a high descent rate, bounced back into the air, and then touched down again on the packed snow surface. As the airplane slowed and its weight transferred from the wings to the landing gear, one main landing gear attach fitting, which had been damaged during the initial hard touchdown, allowed its associated gear leg to partially collapse. The partial collapse of the landing gear resulted in the airplane veering to the right, whereupon the right wing impacted the snow bank along the side of the runway and sustained substantial damage.
NTSB Probable Cause Narrative
The pilot did not reduce the airplane’s descent rate prior to the landing flare/touchdown, which resulted in a hard landing.
