A “key piece” of equipment was recovered on Sunday from the Air Tindi crash site near Marion Lake.
Investigators uncovered the cockpit voice recorder and have sent it to Ottawa for analysis.
Barry Holt is the investigator in charge with the Transportation Safety Board of Canada (TSB). He said the voice recorder was slightly damaged and will add to “other various factors” the team is investigating.
Some of those factors include radar, interviews with Air Tindi and the pilots’ history.
The recorder contains radio calls, conversations in the cockpit and surrounding sounds.
However, Holt says the recordings and analysis will not be made public.
Parts of the aircraft itself will be sent to Edmonton for analysis in the coming weeks.
Two GoFundMe campaigns were launched a little over a week ago for Will Hayworth, 36, and Zach McKillop, 28, the two pilots who died in the accident.
Combined they’ve raised nearly $50,000 for the two families.
The morning of January 30, McKillop and Hayworth took off in a King Air 200 to make their way to Whatì. Air Tindi lost contact with the two pilots between 9 and 9:30 a.m.
That evening, rescuers aboard a Hercules aircraft dispatched from Winnipeg spotted the crash site but it still took them several hours to reach it as they trudged through chest-deep snow.
The following day, both pilots were confirmed deceased.
