What happened

A witness observed the seaplane during the initial climbout from a lake with a high angle of attack. After barely clearing trees, it made a left climbing turn and appeared to join the base leg of the traffic pattern for either the runway or the lake. The seaplane made a steep left turn and entered a left spin, impacting the lake in a nose-down attitude. A review of the of the seaplane’s performance specifications indicated that the seaplane would stall at 38 mph in the accident configuration. A postaccident examination of airframe, flight controls, engine assembly, and accessories revealed no anomalies. There were additionally no mechanical or electrical problems noted with the engine during an engine run and examination.
