What happened
During the initial climb phase following takeoff, an unidentified float plane was seen passing behind a land feature before it vanished from view. The aircraft subsequently struck the surface of the lake while maintaining a left-wing low attitude accompanied by a significant leftward slip. While various reports regarding engine noises heard immediately prior to the crash remain inconsistent, physical evidence from the propeller suggested that the engine was producing little to no power at the moment of impact. However, subsequent inspections of the engine revealed that it remained capable of generating power.
Findings
Investigations into the wreckage uncovered several discrepancies regarding the aircraft's configuration and weight distribution. An external fuel tank had been mounted beneath the fuselage, yet this modification was not documented in the aircraft's logbooks or accounted for in its weight and balance calculations. Additionally, an unapproved bench had been placed within the center cabin area. The investigation also noted that there were no visible methods of load restraint present within the cabin. The accident resulted in five fatalities, including the pilot and four passengers, and the aircraft was effectively destroyed.
