Shaanxi Aircraft has again delayed the roll-out of its Y-9 medium transport as a result of ongoing design changes, but expects to deliver its first production example to the Chinese military in 2009, says company vice-president Liu Bin.

"We have slowed down the development speed of this aircraft to redesign a lot of new things," said Liu during the 19-22 September Aviation Expo in Beijing. Improved avionics and an "integrated display panel" are among the new technologies being incorporated with the Y-9, he said, adding: "we want to make sure the aircraft is perfect."

Shaanxi originally planned to fly the Y-9 - a stretched development of its Y-8F commercial freighter - in 2006, but late last year extended its development schedule into 2007 due to what it described as "small changes" to the aircraft's design (Flight International, 14-20 November 2006).

Liu said the Y-9's first flight is now set to take place during 2008, and revealed that Beijing has already agreed to order the type for delivery from 2009. He declined to reveal how many of the aircraft will be acquired, however, noting that negotiations are continuing.

To be powered by four Chinese-built Wojiang FWJ-6C engines driving six-bladed JL-4 composite propellers, the tail ramp-equipped Y-9 will be capable of carrying a 20t cargo, including land vehicles and other equipment. The transport can also be configured with 106 troop seats, 72 stretchers or to deploy paratroopers, says Shaanxi.
