Air Canada has chosen AAR for a five-year exclusive contract to support the airline’s 89-strong Airbus fleet, which includes A319s, A320s and A321s. ARR’s facility at Duluth International Airport will oversee the work. This five-year contract extends services that began with a letter of intent in late 2012. Initial work took place in ARR’s Miami facility. ARR’s Duluth operation supports three aircraft maintenance lines, and 305 jobs. A new line will open in November adding another 70 jobs.
