Originally ordered by China Airlines on 3 February 1976 at Seattle as the sole 747SP for CI. After rolling out on 28 February 1977, it was used to test if a 747SP Combi variant should be created, but not taken up as a combi. Accepted by CI on 6 April 1977, this 747SP was leased to Mandarin on 1 March 1993 for some troubles involving the ROC flag on China Airlines' aircraft...This registration is currently used on a China Eastern Airlines Airbus A320 without sharklets (cn 6127).
