Probable cause

Pilot's failure to maintain control of the airplane. Contributing to the accident was the pilot's lack of total experience.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

Several witnesses reported hearing a power reduction from the airplane's engine about a minute after takeoff. The airplane then made a steep turn as if to land back on the lake, then stalled and spun into the water. No mechanical problems were found with the airplane or engine.
