Accident
A seaplane conducting a departure from Puvirnituq harbor encountered foggy conditions. Shortly after takeoff, while climbing, the pilot-in-command initiated a left turn. During this maneuver, the left engine lost power. The seaplane subsequently lost height and impacted the bay waters a few dozen yards from shore. All 12 occupants on board were successfully rescued, but the aircraft was lost.
Investigation Findings
Official investigation into the accident determined the probable cause to be a loss of power on the left engine. This loss of power was attributed to the presence of water in the fuel supply system, which compromised engine operation shortly after takeoff.
