Accident Sequence
An airline transport pilot was departing a lake in a float-equipped airplane. During the takeoff initial climb, the engine rpm began decreasing while manifold pressure increased. The airplane attained approximately 400 feet above ground level but failed to continue climbing. Emergency engine failure procedures were performed but did not restore power. The pilot executed a sharp turn to avoid a building and then leveled the airplane just before impact along the shore of the lake.
Postaccident Examination
A thorough postaccident examination of the airframe and engine revealed no mechanical malfunction. The engine was subsequently placed on an engine test stand where it attained full rated rpm without issues.
