Analysis
The airline transport certificated pilot reported he was attempting to takeoff from a slough with a float-equipped airplane on a Title 14, CFR Part 135 on-demand air taxi flight. He stated he aborted the first takeoff attempt due to shifting winds created by local thunderstorms, and elected to takeoff in the opposite direction. Shortly after liftoff, the pilot reported the airplane encountered a severe downdraft, and descended onto the tundra, striking Alder and Willow bushes. The airplane sustained substantial damage to both wings and wing lift struts.
