Bombardier has announced a deal for three C-Series aircraft, a day before the Singapore Airshow gets under way.
The firm order for the three CS300 aeroplanes is worth $228m (£139m) and bodes well for the company's Belfast base as the wings, and other parts of the plane, are made in the city.
The buyer didn't want to be named, but is said to be an existing customer, and has pushed the order book for the C-Series through the 200 mark.
Although a relatively small order, the deal will go some way to helping boost confidence in the mid-range jet after a slow uptake of orders.
It has also faced a delay to delivery of the first aircraft by around 18 months to the second half of 2015, a schedule which puts it up against a similar model from Airbus.
Mike Arcamone, president of Bombardier Commercial Aircraft, said interest was building and progress was being made with development.
"As of today, we have more than 10 aircraft in various stages of testing and production, and together with the key components being manufactured at our partner sites for aircraft that follow, the C-Series aircraft programme is progressing steadily," he said.
He will no doubt be hoping that further orders are forthcoming in the days ahead.
Bombardier is part of a nine-strong delegation of Northern Ireland companies on a trade mission to the show led by Enterprise Minister Arlene Foster.
