CH-146 Griffon Limited Life Extension

Project summary

The Griffon Limited Life Extension (GLLE) project will extend the life of the Royal Canadian Air Force’s fleet of 85 CH-146 Griffon helicopters to at least 2031. To do so, we will:

  • replace a number of the aircraft’s avionics systems, including communications radios and cryptographic equipment, cockpit voice and flight recorders, navigation systems, automatic flight control systems, and control display units,
  • upgrade the cockpit displays,
  • upgrade engines, and
  • integrate sensor systems.

The project will also upgrade flight simulation and training devices to ensure alignment with the fleet modifications, and the provision of equipment and spare parts.

The CH-146 is a proven, durable utility tactical transport helicopter that fills a number of functions. It has participated in tactical troop transport, reconnaissance, escort and surveillance, casualty evacuation, disaster relief, special operations aviation support, and search and rescue.
