US aerospace giant Boeing has said that the Dubai aircraft leasing firm Dubai Aerospace Enterprise has cancelled an order for 32 of its best-selling single-aisle 737 aircraft.

The Boeing spokesman, Mr Doug Alder, confirmed the name on Friday after Boeing first announced the cancellation without identifying the customer.

He said Dubai Aerospace Enterprise, launched in February 2006 and partly owned by the crisis-strapped Government of Dubai’s investment arm, still has 56 orders on Boeing’s books. It had ordered 35 737s, 15 747s and six 777s, he said.

The Chicago-based Boeing has taken 32 new orders for 737s in the year to date: Alaska Airlines, 15 planes; the US Navy, six; one from a non-airline operator; and 10 more just revealed on Thursday, from “unidentified customer(s)’’.

But according to Boeing’s weekly update on changes in orders and deliveries for commercial aircraft, the DAE cancellation left orders for 737s so far this year at a net zero.

In the year-to-date, Boeing has also received orders for two of its long-haul 777s from American Airlines.
