Analysis

Immediately after taking off from the water, this private pilot executed a low altitude steep left turn which resulted in a stall-spin into the lake. No evidence to indicated pre-accident failure or malfunction of the flight control, engine, or airframe were noted. No medical factors were identified which could be considered casual.
