Boeing hit with new setback after finding more faulty rivet holes on 737

Ryanair had said it foresees no delays for the yet-to-be-certified Max 10 plane

Boeing said a worker at a supplier flagged that two holes in the plane’s fuselage may not exactly meet specifications.

Boeing found more mistakes with holes drilled in the fuselage of its 737 Max jet, a setback that could further slow deliveries on a critical programme already restricted by regulators over quality lapses.

The latest manufacturing slip originated with a supplier and will require rework on about 50 undelivered 737 jets to repair the faulty rivet holes, Boeing commercial chief Stan Deal said in a note to staff. While he didn’t identify the contractor, a spokesman for fuselage supplier Spirit AeroSystems said it’s aware of the issue and will conduct repairs.
