Boeing Co. resumed flights of its new 737 Max jetliners on a limited basis Friday, setting the stage for the first commercial delivery after a potential engine flaw temporarily grounded the single-aisle aircraft.

Regulators cleared the planes to fly as long as they’re powered by spare engines that don’t include the possibly defective part, Boeing spokesman Doug Alder said Friday. Supplier CFM International, a joint venture of General Electric Co. and Safran SA, alerted the plane-maker late last week to a manufacturing quality problem with low-pressure turbine discs in the Leap engines.
