Another worrying development for thousands of workers concerned about their jobs at Bombardier here in Northern Ireland tonight.
There has been a second ruling by US Officials calling for an extra 80% tariff on it's CSeries jet.
It follows last week's decision to slap preliminary tariffs of nearly 220% on Bombardier.
Washington claims the price the manufacturer has put on the planes is well below cost and amounts to dumping.
These extra duties will effectively quadruple the price of the CSeries which is partly built in Belfast.
More than 4,000 people are employed in Belfast by Bombardier and thousands more aerospace jobs in Northern Ireland are supported through the manufacturer's supply chain.
Unite Union's Davy Thompson has attacked Theresa May's lack of action on the dispute.
