The Transportation Safety Board says its team has recovered a GPS device from the wreckage of a helicopter that crashed in rural Tweed, killing four Hydro One workers.
But the agency says the chopper didn’t have a cockpit voice recorder or a flight data recorder — neither of which was required.
The TSB says it has gathered initial statements from witnesses to Thursday’s crash in Tweed and now plans to examine maintenance records, pilot training and several other factors.
The chopper crashed as it was getting set to land.
Hydro One has grounded its eight helicopters until a thorough review of safety protocols and equipment is complete.
