Refueling Northwest Airlines airplane, Minneapolis Minnesota, 07/17/1950.Minneapolis-St Paul-based Republic Air Lines acquired a large fleet of Convair 580s following take-over of North Central Airlines in July 1979. Seen here awaiting engine start at Atlanta on November 18 1983, N3423 (c/n 77) was originally delivered to Braniff Airways on May 22 1953 as Convair 340 N3423. Following purchase by North Central in October 1967 the aircraft was converted to Allison power and re-entered service in March 1968. After Northwest’s take-over of Republic in October 1986, the aircraft remained in service until retired in 1989. Having passed through the hands of a number of owners, the 580 was sold to Los Pequenos Airlines in Venezuela as YV-973C in May 1996.
