Analysis narrative
The sport pilot was performing a takeoff from a private grass strip for his first solo flight in a weight-shift airplane. Shortly after takeoff, the airplane entered an uncommanded left bank. The pilot attempted to level the wing, but was unable to regain control of the weight-shift airplane. The weight-shift airplane continued a left turn, descended, and impacted terrain. The cause of the uncommanded left bank could not be determined. Due to the remote location, an examination of the wreckage was not conducted by a federal agency.
