The Directorate of Flight Safety released an initial report this week on the CH-147 Chinook accident in the Ottawa River earlier this summer.
According to the report, during its descent, the helicopter impacted the water “with high energy” at 12:10 a.m. local time.
“Shortly after departure, the helicopter turned left and, once cleared of the tree line on the west shore of the Ottawa River, descended to tactical altitudes as per the mission profile,” stated the report about the activity before impact.
The investigation is currently ongoing and is focusing on human, technical and environmental factors.
