Bombardier has landed a major contract for its Belfast-built business jets.
The Canandian-owned aerospace giant has secured a firm order for six CRJ900 aircraft from an unidentified customer, with the option for a further six.
According to the book price, the order could be worth up to £427m.
A large chunk of the fuselage is designed and built here, along with the nacelles and wing components.
Fred Cromer, president of Bombardier Commercial Aircraft, said: "In the last five years, more than 25 new airlines have joined the family of CRJ Series operators, and this is testament to the tremendous value this aircraft can deliver to customers thanks to its unmatched performance and economics."
Bombardier is locked in a trade tussle with Boeing, which claims it's selling its C Series passenger planes at below cost, and has been unfairly subsidised by Canada's regional government in Quebec. The US Department of Commerce has since imposed a tariff of almost 300% on sales to America.
