This 1953 Convair was built as a 340 for Delta Air Lines (N4802C). Bought by North Central Airlines in 1962, it was converted to a 580 in 1969. Bought by the James Bay Energy Corporation in 1976 for transportation to their giant hydro-electric project in Northern Quebec. Operated at first by Quebecair for the company, Inter-Quebec and Air Inuit took over as the aviation scene changed in Canada. Sold to the public utility Hydro-Québec in 1994, the airliner was withdrawn in 2001 and the registration cancelled at the end of that year.
