Workers at an aircraft firm are under investigation after components from the new A380 Superjumbo were found for sale on the internet.
The Airbus A380 will make its maiden test flight in April
Bosses at Airbus UK, which makes the A380 wings at its plant in Broughton, Flintshire, spotted parts for sale on the auction site eBay.
A spokeswoman said a "thorough investigation" was underway.
No-one has been disciplined but it is understood one worker connected to the plant has been questioned.
Airbus UK are trying to determine whether any workers were trying to make extra cash by selling spare or scrap components to plane buffs.
A spokeswoman said: "All parts for our aircraft, including scrap, require rigorous documentation and are strictly controlled.
"The incident will be thoroughly investigated before we decide whether any action against our employees is necessary."
She refused to reveal what parts were on sale but said they were "very small and of little value".
More than 6,000 workers are based at Broughton, many involved in the wing assembly.
The double-decker A380 Superjumbo, which can seat 555 passengers, was officially unveiled last month in Toulouse, southern France.
A search of the eBay site on Tuesday revealed no A380 parts for sale, though other plane parts, model planes and laminated safety cards were on sale.
An eBay spokeswoman said unlawful sales would be taken down and users with concerns about illegal activity should email the customer care department immediately.
Airbus say no one has been disciplined but it is understood a worker connected to the Broughton plant has been questioned as part of the investigation.
