A new passenger plane partially built in Belfast is almost ready for take-off after a major series of tests passed off successfully.
Bombardier Aerospace said it has completed the first full switch on of the main electrical distribution system on the first CSeries flight test vehicle.
The company has also completed the two most significant wing static tests required for first flight and that safety-of-flight tests are progressing well on the 'Aircraft 0' test rig for the CSeries aircraft.
The wings of the jet were invented and developed from the company's Northern Ireland base and are made in a specially-built facility in east Belfast before being shipped to Canada for assembly.
Earlier this month the Belfast Telegraph received a tour of the factory and was among a number of media outlets which saw the first CSeries flight test vehicle being presented to the world via a live web link-up to Bombardier Aerospace factory in Quebec.
Michael Ryan, vice-president and general manager of Bombardier Aerospace in Belfast, said that the completion of the wing static tests is another important milestone in the programme.
"The success of these latest tests is a direct outcome of the major investment we made in Belfast in researching, developing and testing the unique composite process we're using for the wings, well before production got under way."
