Kalitta Charters has ordered a second Boeing 737-400SF conversion from Aeronautical Engineers (AEI), to be delivered in June 2016.

The aircraft, which was built in 1989, will be converted at Commercial Jet’s Miami facility. The converted 737-400 can accommodate 10 88 by 125 inch unit load devices, which AEI says is unique due to its main deck cargo door location being 40 inches back from the competition. AEI says this increases capacity by 10 per cent.

This is the fifth 737-400SF order AEI has received this year. In January, it received an order from an aviation fund, in February ASL Aviation ordered three 737-400SFs, one to World Star Aviation and one for JMV Aviation.
