From the above link; " Bell Helicopter Textron Canada Limited will be undertaking design work to extend the life of Canada’s fleet of 85 CH-146 Griffon helicopters
to at least 2031."
"The first phase of this life extension is the definition phase, during which Bell Helicopter Textron Canada Limited – the original equipment manufacturer – will develop design changes to upgrade the helicopter’s avionics systems, engines, and cockpit displays, and integrate sensor systems."
From the 10.01.2018 issue of the
Canadian Defence Review:
"GRIFFON LIMITED LIFE EXTENSION PROJECT
The GLLE project will extend the life of the CH-146 Griffon beyond the current Estimated Life Expectancy so that the aircraft can continue to be operationally relevant and remain a vital contributor to the readiness of the Canadian Army and the Canadian Special Operations Force Command units well into the future.
The extension will bridge the gap until a replacement capability is acquired through the
Tactical Reconnaissance Utility Helicopter project. GLLE aims to extend CH-146 operating life to 2030+ through the replacement of obsolete avionics, instrumentation and displays with an integrated digital systems architecture. It may also include new digitally controlled engines as a package.
Flight simulators will also be modified to conform to the fleet. Finally, the project will ensure integrated logistic support, supply of initial spares and training. According to an April 2017 RCAF Director of Air Requirements (DAR) document, the preliminary estimate of the cost of GLLE ranges between $500 million to $1.5 billion."
Interesting, back in 2011, when the last contract for a
CH-146 Griffon upgrade was awarded, the plan was to retire it in 2021.
