Boeing and a major supplier have identified a new manufacturing flaw that might cause delays in delivering the 737 Max, Boeing’s popular aircraft. The issue involves improperly drilled fastener holes in the aft pressure bulkhead on certain 737 Max models.
While this affects near-term deliveries and requires inspections and rework, Boeing emphasizes that the flaw doesn’t compromise flight safety for planes already in service.
Spirit AeroSystems, which manufactures the fuselage for the 737 Max, acknowledged the flaw’s impact due to its multiple suppliers but will continue delivering fuselages to Boeing. This setback hampers Boeing’s goal of delivering 400 to 450 Max jets this year. This situation has led to concerns about a possible downward revision in their plans.
This development also highlights supply challenges faced by aircraft manufacturers in recent years. The delay affects Boeing’s revenue flow as they receive a significant portion of the purchase price upon delivery.
Furthermore, such delays have financial implications in terms of inspection and corrective work expenses.
It’s worth noting that Boeing’s 737 Max series previously faced a global grounding after fatal accidents, and production glitches have disrupted the deliveries of their larger 787 jetliner as well.
As a result of these challenges, both Boeing and Spirit AeroSystems have seen declines in their stock values.
