N945L was returned to McDonnell Douglas (the two manufacturers merged April 1967) on May 28, 1979, to be converted into a DC-9-14. This model had a takeoff gross weight increase of 8,600 lb (3,901 kg) to 86,300 lb (39,145 kg) and was powered by 14,000 lb (6,350 kg) Pratt & Whitney JT8D-1 that replaced the original 12,000 lb (5,443 kg) JT8D-5 turbofans.
The aircraft was sold to Itavia of Italy and registered I-TIGA on October 12, 1971. Twelve years later it returned to the USA and was registered N925AX to Airborne Express in August 1983. It was stored in 2005 and scrapped in July 2006 and the registration was cancelled on April 25, 2007, reasoned as "permanently withdrawn from use".
