Mr. Petar Cenkov, General Manager of Cargo Air stated that “Our decision to convert a second B737-300SF with AEI was based upon two factors, AEI having become a Boeing Licensed STC Provider and its conversion design providing nine 88”x125” positions. This is the only conversion available that offers 9 full positions and our customers are willing to pay a premium for this additional space”.

AEI’s B737-300 shall provide Cargo Air with a Main Deck capable of carrying multiple ULD’s including:

-- 9ea 88”x125” ULD’s or

-- 9ea 88”x108” ULD’s or

-- A mixture of both

This unique flexibility has been designed by AEI to allow the operator to immediately adapt to multiple ULD configurations at a moment’s notice. When combined with proven reliability, the AEI Converted B737-300SF will allow Cargo Air to keep their aircraft where they belong “In the air, generating revenue”.
