Narrative:
The helicopter crashed near Tweed, Ontario, killing four occupants.
Helicopter was on approach to land in a staging area, after picking up Hydro One crews from towers in a transmission tower right of way.

The linemen were conducting maintenance work on high-power transmission lines.
As part of the work being conducted, a few bags used for carrying tools and supplies were carried externally on a platform extending out of the right side of the fuselage. These bags, when carried externally, are normally attached with double-lock carabiners.
Shortly before the accident, the pilot picked up the 3 linemen at the base of a tower and was transporting them to a nearby staging area.
While nearing the staging area, one of the bags that was being carried externally blew off the platform and, along with its attached carabiner, struck the tail rotor.
Shortly thereafter, while the pilot was attempting to land, the helicopter departed from controlled flight, all 3 passengers became separated from the helicopter while it was still airborne. The helicopter subsequently crashed nearby.
