The largest supplier for the Boeing Co.’s 737 Max had been revving up to jump to a record production pace in June for the single-aisle jet.
Instead, Spirit AeroSystems Holdings Inc. is rushing to preserve cash, manage a mountain of inventory and shield its workforce from layoffs. Since the best-selling 737 model was grounded following a March 10 crash, the second deadly accident in five months, Boeing has scrapped the planned output increase and slowed work in its own factory south of Seattle.
