Built as a 440 ordered by Real Transportes Aéreos but delivered to General Motors (N5123) August 1959. Converted to a 580 in May 1960 and flying with GM until August 1994. Cypress Airlines brought the airplane to Canada the first time in 1996 (C-GTTA). It would later fly with Air Inuit and Hydro Quebec before going to Pionair, first as ZK-PAL and later VH-PAL. The aircraft was ferried to Canada in 2009 to become C-GYXS and stored in Conair's compound without the registration markings.
