The first Boeing 737 Max 9, Boeing's newest commercial airplane, sits outside its production plant in Renton, Washington. Norwegian Air Shuttle is also slated to receive its first 737 Max in late May. The newest 737’s progression to market had gone smoothly until this week, when Boeing said it would ground the fleet of more than 20 Max planes. Boeing also had other Leap engines on hand that were unaffected, Alder said. The components came from a single disc supplier, and the 737 Max planes being flown now use discs from two other manufacturers.
