Grumman G-21A Goose N88821 was imported to Canada in 1973 and sold by Viking Air at Victoria Airport (YYJ) after overhaul to Alert Bay Air Services in January 1974. The company served the mid-British Columbia coast from a waterfront base in Alert Bay on Cormorant Island located a few miles off the northeast coast of Vancouver Island. Acquired by Jim Pattison Industries in the early 1980s during the creation of AirBC and primarily operated by sister company Trans-Provincial Airlines until it ground looped on landing at Sandspit Airport in Feb. 1991. The wreck was acquired by the Tongass Historical Society in Ketchikan (AK) in 1992 as N88821 and was still under restoration for static display with them by 2022.

This Grumman Goose was photographed at Stewart Airport (CZST) while operating scheduled service to Prince Rupert. In the early 1980s, Jim Pattison Industries bought and merged several coastal airlines to form Air BC, including Trans-Provincial Airlines (TPA) which flew C-FEFN in this yellow colour scheme. When Air BC added new Dash 7 routes, most of its seaplane services (except DHC-6 routes) were transferred TPA, which became separate airline again. Steward is at the head of the Portland Canal which forms part of the border with SE Alaska. It is the northernmost coastal community in BC.

Trans-Provincial Airlines was acquired by the Pattison Group in the early 1980s when Air BC was formed but operated as a separate division primarily serving the north coast of British Columbia. The main base of operations was the former wartime RCAF seaplane base at Seal Cove in Prince Rupert. Goose CF-EFN operated on the BC coast from the early 1970s until Feb 28, 1991 when it was damaged when it ground looped on landing at Sandspit Airport (CYZP). The wreck was acquired by the Tongass Historical Society in Ketchikan (AK) in 1992 as N88821, and was still under restoration for static display with them by 2022.

This Goose, built for the Royal Navy, was transferred to the USAAF as 42-106981 before delivery. It went to the Reconstruction Finance Corp after WWII and became NC88821. Flying in Alaska, the amphibian re-registered N88821 after an overhaul in 1949. It came to Canada 20 years later and was registered CF-EFN. Damaged in a ground loop during landing February 28, 1991, the wreckage was stripped of parts to rebuild another Goose. The remains were sold to Tongass Historical Society at the end of 1992; the aircraft was rebuilt using parts from yet another Goose and returned to N88821.
