The Agusta AW119 Koala helicopter (registration C-GSLY) owned by Skyline Helicopters and leased to Northern Escape Heli Skiing, was conducting heli-skiing operations 21 nautical miles (NM) northwest of Terrace Airport (CYXT), British Columbia (BC) with a pilot, a ski guide, and 5 passengers on board. During the flight, the helicopter impacted terrain. The pilot and 2 passengers were fatally injured, and the ski guide and 3 passengers received serious injuries. The helicopter was destroyed. The emergency locator transmitter (ELT) did not transmit a signal. Three helicopters that were conducting heli-skiing operations nearby responded to the accident and airlifted the ski guide and 3 passengers with serious injuries to ambulances that transported them to hospital. One passenger later died as a result of their injuries.

A Civil Aviation Safety Inspector (CASI) looked into this occurrence. Maintenance was carried out on the night before the accident which included a transmission oil and filter change and a main rotor damper replacement. Last inspection carried on the aircraft was a 50 hour/60 day inspection at 4729.9 airframe hours on 09 Jan 2024. Corrective actions will be implemented once the root cause(s) of the accident are known after the TSB investigation report is received.
