AIRBUS UK's flagship A380 project could be grounded and the millions spent on the Broughton site wasted if Mostyn Docks is not permitted to dredge a navigation channel in the River Dee.
This is the stark message from Airbus UK boss Brian Fleet after it was revealed the dock still did not have permission to dredge the channel.
The first set of the 555-seater Super-Jumbo's giant wings are due be shipped out of Mostyn next month but this week bosses at the docks issued statement which has set alarm bells ringing.
The bed of the Dee needs to have a navigation channel dredged along it for larger ships to get in and out of the docks.
Regulators who monitor the Dee have delayed approval for the work, a decision which has already forced P&O to axe ferry services from the port as boats could only sail in and out on a high tide.
The statement reveals that Airbus ships, which will carry the wings to France, are a similar size to the ferries and will need the same dredged channel to be able to collect the wings.
'First of all, our thoughts go out to Jim O'Toole and the employees at Mostyn who will lose their livelihoods as a result of P&O pulling out of the docks,' said Mr Fleet, senior vice-president in charge of manufacturing for Airbus UK.
'But this announcement has revealed a problem which will cast a cloud over the whole A380 project. Britain's involvement in the project could be over if Mostyn cannot dredge and we find ourselves landlocked.
'You cannot have a port without dredging, it is a fact. North Wales does not need any more beaches, it needs a port - a trading link with Europe and the world.
He added: 'I don't even know why this is up for discussion. When Mostyn got permission to operate as a port dredging should have been expected by the Environment Agency.
'This transport link is vital to the A380 and is the first real setback. We have invested many, many millions in creating a route to the Dee for the wings to get from the factory to a barge, from a barge to a ferry at Mostyn and eventually down to Bordeaux where another barge will take the wings to Toulouse.'
Mr Fleet said: 'All this has been paid for by Airbus and it's now in jeopardy. This stretch of the Dee is man-made anyway. The original river through Chester silted-up and a new route for it was carved.
'This man-made channel needs dredging. We have enough beaches and deserted sand-banks in North Wales, we need the port.'
He added: 'This disruption has come at the 12th hour. The first set of wings are due to be transported in a few weeks and the barge is already undergoing tests.
'We are now in contact with the Environment Agency and are hoping they grant dredging permission very soon.'
A spokesman for Airbus said: 'We looked at a number of options when we originally tackled the problem of transporting the wings and Mostyn was, and still is, by far the best option,' she said.
'We do have contingency plans which we cannot reveal at the moment. But they would cost yet more money.
'We are hoping regulators take into account the economic concerns as well as the environmental impact of their decision.'
