The federal transportation safety watchdog is expected to release the findings of its probe of a Hydro One helicopter crash near Tweed that killed four men nearly two years ago.
A preliminary investigation by the Transportation Safety Board of Canada determined that an improperly secured tool bag hit the rear rotor of the helicopter before the aircraft crashed on Dec. 14, 2017.
The full board investigation was expected to examine helicopter maintenance records, pilot training, operational policies and previous occurrences involving the helicopter model involved.
The crash killed the pilot and three line workers who had recently boarded the aircraft.
They had departed from the base of a high-power transmission tower and were en route to a nearby staging area when the crash took place.
Investigators also found that two of the three seatbelts in the helicopter’s passenger area were unfastened.
