WICHITA, Kan. (AP) — A bankruptcy judge sided Monday with a group of current Hawker Beechcraft customers who balked at a move by the Kansas plane maker to immediately sell off its inventory of discontinued Hawker 4000 jet aircraft at substantial discounts as part of the company’s bankruptcy proceedings.

Hawker Beechcraft wants to sell the remaining inventory on “an expedited basis,” without bankruptcy court approval of each sale, because it believes the value of the discontinued line of planes will continue to decline as competitors introduce new aircraft and further dilute the company’s share in the business jet industry.
