On 12 March 2009, one of PAL Aerospace's Maritime Patrol Aircraft was first on the scene of Cougar Helicopters Flight 91's ditching, flying "top cover" until other help could arrive, leading to the rescue of the sole survivor. Between 2011 and 2012, the company divided into two operating segments. Remaining under the same ownership, two separate corporate divisions were formed: PAL Aerospace and PAL Airlines. Provincial Aerospace remains as the parent company. PAL Aerospace is an international aerospace and defence contractor with maritime patrol and intelligence, surveillance, and reconnaissance operations in Canada, Curaçao, under contract to the Netherlands Ministry of Defence, and the United Arab Emirates. The Cessna Citation jets, and the charter and MEDIVAC King Airs are also operated by PAL Aerospace. PAL Aerospace is a speciality operator (Part 702, 703, and 704). PAL Aerospace has the MRO operations providing integration, modification, and maintenance and overhaul services. PAL Airlines is focused on regional airline operations with 704 and 705 aircraft which in 2011 comprised Dash-8s, Twin Otters, and a Metroliner, at four bases in St. John's, Halifax, Goose Bay, and Montreal. In November 2014, the company was purchased by Exchange Income Corporation, a Toronto Stock Exchange (TSX)-listed stock that owns regional airlines and several manufacturing companies, for a combination of cash and stock worth about $246 million. In June 2017, PAL Airlines established Air Borealis LP in partnership with the Innu, the First Nations people of Labrador (through Innu Development LP) and the government of Nunatsiavut (through the Nunatsiavut Group of Companies).
