Aircraft Accident/Incident Report

Jefferson, Oregon 97352
Friday, June 17, 2011 16:40 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that, while on short final for landing at an airstrip located atop a plateau, the airplane experienced a thermal lift then a downdraft, which caused the airplane to descend. The pilot added power; however, insufficient altitude existed to arrest the sink rate, and the airplane subsequently landed hard. One of the wings and the pontoon/landing gear sustained substantial damage. The pilot reported no preimpact malfunctions or failures with the airplane or engine that would have precluded normal operation.

NTSB Probable Cause Narrative

The pilot's failure to maintain airplane control while on short final after experiencing a downdraft, which resulted in a subsequent hard landing.
