What happened
The incident occurred shortly after the aircraft departed from Ramsey Lake in Sudbury. While executing the initial climb to an altitude of approximately 200 feet, the seaplane experienced a stall. The loss of lift caused the aircraft to descend rapidly and impact the water surface. Following the crash, all five individuals on board were successfully rescued. The structural damage sustained by the airframe was extensive, rendering it damaged beyond repair.
Findings
Canadian authorities investigated the event and determined that the primary factor leading to the accident was insufficient airspeed. The aircraft did not achieve adequate velocity after leaving the water surface during takeoff. This lack of speed resulted in an aerodynamic stall during the climb phase, which directly caused the subsequent impact with the lake.
