N260HC
DEHAVILLAND BEAVER DHC-2 MK.3
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.
