Checks are being made for potential “hairline cracks” in the wings of Boeing 787 Dreamliners.
The move came after Japanese supplier Mitsubishi Heavy Industries warned Boeing that a change in its manufacturing process may cause cracks.
The US aircraft manufacturer said the issue may affect nearly 40 planes and there may be “some delays in deliveries”.
However, Boeing added that it was confident “the issue does not exist in the in-service fleet,” the BBC reported.
“The affected areas are very small and the time required to address the issue will vary between one and two weeks,” the company said.
“There may be some delays in deliveries, but we expect no impact to 2014 delivery guidance.”
Thomson Airways and British Airways are current UK operators of the 787, soon to be followed by Virgin Atlantic.
