Upon completion of this new order, ACS will have a total of 40 AEI B737-800SF freighter conversions in their fleet. In October of 2020, ACS placed its first order for the B737-800SF freighter conversion and has since become AEI’s largest customer for the B737-800SF.All aircraft in this order will be inducted and completed during the 2024 calendar year. The modification touch labour and maintenance requirements for the six conversions will be split between the authorised AEI Conversion Centers of STAECO and HAECO. AEI is currently the only conversion company to have ETOPS 180 approval on the 737-800 freighter conversion. Additionally, AEI can convert all 737-800 line number aircraft, including those with Split Scimitar winglets. The AEI converted B737-800SF freighter offers a main deck payload of up to 52,700 lbs.
