Bulgaria-based Cargo Air has ordered its fifth Boeing 737-800SF freighter conversion from Aeronautical Engineers Inc (AEI). The aircraft, (MSN 30881) is slated to commence modification in June 2023 with all conversion-related touch labor to be performed by authorised AEI conversion centre Commercial Jet in Miami. Cargo Air purchase and fleet acquisitions director Angel Petrov said: “AEI has provided Cargo Air with sustainable freighter solutions since 2007. They have listened to our needs and collaborated with us on product innovations, many features which are not available on other B737-800 freighter conversions. “This is our fifth B737-800SF freighter with AEI and we will continue to rely on them for our fleet renovation in the future years to come while replacing our B737 Classic freighters with 737NG freighters.” Upon completion of this order, Cargo Air will operate a total of 16 AEI freighters, including a mix of B737-300SF, B737-400SF, and B737-800SF freighters.
