Airbus says it has now found a way to fix problems with faulty wings on its flagship A380 aircraft.
The wings are made at Broughton in Flintshire, but two types of cracks were discovered during inspections in January.
The company's chief executive said at the time that the planes were 'safe to fly', but began an internal investigation into the cause of the cracks.
Now the firm says that it has got a solution to fix them.
The news comes as Welsh Secretary, Cheryl Gillan, returns from a tour of the Airbus facility in Toulouse.
She used the French visit to fly the flag for the Broughton plant, where six thousand people are employed.
She is also campaigning for the company to create more jobs in North Wales.
