Boeing Co. said Tuesday that it had found debris in the fuel tanks of undelivered 737 Max jetliners, the latest setback in the plane maker’s efforts to address quality control problems.
The debris was found in an undisclosed number of jets parked at facilities in Washington state and Texas, where planes have been stored since a global ban on commercial Max flights was imposed following two crashes that killed 346 people.
The company has stored the planes awaiting approval from regulators to restart Max flying after changes are made to the plane’s flight-control software and training regimes. Boeing /zigman2/quotes/208579720/composite BA +1.01% said it didn’t expect the latest problem to push back the aircraft’s return, which it has said could occur by midyear.
The company said the debris was discovered during “routine” inspections, but didn’t detail how many planes were affected or when they rolled off the production line. The problem was first reported on leeham.net, an aviation news site.
