Alpine Aerotech and Heli-One have been contracted to perform modernisation work on the Royal Canadian Air Force’s fleet of Bell CH-146 Griffon helicopters.

Awarded by Bell’s Canadian subsidiary, the contracts follow the selection last May of the airframer to head the Griffon Life Limited Extension (GLLE) programme.

A total of 85 helicopters are covered by the upgrade programme

Bell will modify the first nine of a total 85 helicopters, with the remaining 76 examples to be updated by the two subcontractors.

Both subcontractors are based in British Columbia in Western Canada: Alpine is headquartered in West Kelowna, while CHC Helicopter subsidiary Heli-One has its main base in Richmond near Vancouver.

The GLLE project will see the CH-146 fleet – delivered between 1994 and 1998 – operated into the 2030s.

Under the C$800 million ($590 million) programme, planned updates include replacement of the avionics, upgraded engines and integration of new sensor systems.

Other GLLE partners include CMC Electronics and Pratt & Whitney Canada.
