This article is for subscribers only.
Boeing Co. is checking for hairline wing cracks on about 40 of its 787 Dreamliners after supplier Mitsubishi Heavy Industries Ltd. alerted the planemaker about possible risks to the aircraft.
A change in the wing-manufacturing process at Tokyo-based Mitsubishi may have led to cracks in a section of a wing rib, Marc Birtel, a Boeing spokesman, said yesterday by e-mail. All the affected jets are still in production, and Boeing is taking corrective steps, Birtel said, without elaborating.
