Probable cause

The pilot's inadequate weather evaluation, which resulted in the airplane encountering a severe downdraft during takeoff initial climb, and an in-flight collision with terrain. Factors associated with the accident were a thunderstorm and a downdraft.

Analysis

The airline transport certificated pilot reported that 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 that 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 that 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.
