Convair 580
The Convair 580 is a Convair 340 or 440 piston airliner rebuilt with two Allison 501 turboprops under a supplemental type certificate, SA4-1100, now held by Kelowna Flightcraft of British Columbia, which also holds the 340 and 440 data sheet. The 340 itself was approved in March 1952 and the 440 in January 1956. ICAO files the turboprop Convairs, the 580 and the CV-600 and CV-640, under the code CVLT, along with Kelowna's CV-5800 and the Canadair CL-66, the Canadian-built turboprop version.
