What happened
During an enroute phase of flight, the pilot encountered a critical mechanical issue resulting in a double engine failure. With no power remaining, the crew was compelled to execute an emergency landing on the water. The aircraft impacted the surface of the Saint Lawrence River off the coast of Mont-Joli, Quebec, where it crash-landed on the ice.
Despite the severity of the impact and the subsequent sinking of the airframe through the ice, all seven occupants were successfully rescued from the water. The aircraft itself was not recovered and is considered lost.
Findings
The official investigation determined that the immediate cause of the incident was the loss of power in both engines. This failure was attributed to fuel exhaustion, which rendered the aircraft unable to maintain flight or reach a suitable runway.
