The Boeing Company is converting two MD-11 passenger airplanes into freighters and updating their flight deck features and cargo-handling system for Aeroflot-Cargo.

The move is expected to help Aeroflot-Cargo improve its operational efficiency.

"These aircraft represent a very substantial investment. By putting them in the hands of the original manufacturer for conversion, we can extend the life of the aircraft and maximize their capabilities," said Aeroflot-Cargo general director Andrey Goryashko. "The Boeing Converted Freighter programme gives us the confidence and support that we expect with a new airplane while allowing us to make the most of the fleet we already have."

"This conversion programme allows Aeroflot Cargo to streamline and modernize its operational systems across its freighter fleet," said a Boeing Commercial Aviation Services spokesman in a statement.

Aeroflot-Cargo currently operates four DC-10 Freighters. In addition to these two MD-11s, Aeroflot-Cargo has committed to lease three more MD-11 Boeing Converted Freighters from the Boeing Capital Corporation between now and 2008.

Modification work on the two aircraft will begin in November next year.

In total, Boeing has converted more than 100 MD-11 passenger airplanes into freighters.
