Boeing Finds New Defect in Ongoing Struggle to Produce Dreamliner 787

Boeing Co
and U.S. regulators said Thursday that some titanium 787 Dreamliner parts were
improperly manufactured over the past three years, the latest in a series of
problems to plague the wide-body aircraft.
The quality issue does not affect the immediate safety of
flights, the company and the Federal Aviation Administration (FAA) said.
Boeing said the parts were provided Leonardo SpA, which
bought the items from Italy-based Manufacturing Processes Specification (MPS).
MPS is no longer a supplier to Leonardo, Boeing said. Shares in Italy's
Leonardo extended losses and were recently down 5.5%. Boeing shares were down
1.3%.
Leonardo declined to comment. MPS did not immediately
respond to a request for comment.
The parts include fittings that help secure the floor beam
in one fuselage section, as well as other fittings, spacers, brackets, and
clips within other assemblies.
Undelivered aircraft will be reworked as needed, Boeing
said, adding that any fleet actions would be determined through its normal
review process and confirmed with the FAA.
The defect was found as the plane maker grapples with other
problems in its 787 that have caused it to cut production and halt deliveries
since May.
Problems started in September 2020 when the FAA said it was
investigating manufacturing flaws. Airlines using that model removed eight jets
from service.
Boeing was able to resume deliveries of the 787s in March
after a five-month hiatus – only to halt them again in May after the FAA raised
concerns about its proposed inspection method.
In July, the FAA said some Dreamliners had a manufacturing
quality issue near the nose of the plane that must be fixed before Boeing can
deliver to customers.
