Boeing’s troubles are bleeding out to its supply chain, where uncertainty over production rates has suppliers guessing at how many parts to make to avoid the cost of holding too much inventory, reports Financial Times (May 29, 2024) . It has slowed manufacturing of its workhorse jet, the 737 Max, as it tries to improve production quality following a recent door panel blowout on a flight. And it is facing an FAA deadline to deliver a plan that addresses a “flawed safety culture”.
The production slowdown is testing the resilience of a brittle aerospace supply chain that already has faced years of price cuts and choppy production thanks to Covid-19 and two fatal crashes that grounded the Max worldwide. Without a well-oiled supply chain, Boeing will struggle to deliver jets to airlines clamoring for them, and could destabilize labor in an industry that employs hundreds of thousands of workers.
The FAA has capped Boeing’s production of the Max at 38 per month. (The company is currently building even less). That affects the operations and finances for suppliers. The ones that do a lot of business with Boeing were “feeling the pain at the moment. Everybody was expecting a ramp-up in the production of the 737 and 787. They may have invested in people or capacity to meet that ramp- up, and when they get pushed back, it’s a problem,” said one industry consultant.
Spirit Aerospace, which produces the 737 fuselages, has had its own struggles with quality and has been the most high-profile casualty of the slowdown on the Max. Boeing stopped accepting those fuselages that do not meet specifications in an effort to reduce rework at its own Washington state factory, where rework performed increases the likelihood of manufacturing errors.
Spirit is far from alone. Howmet Aerospace, Triumph Group, Hexcel, Senior and ATI all have been affected by the slowdown on the 737. Triumph, for example, supplies $300,000 worth of equipment on each 737 Max and $1 million worth on each 787. It has slowed ordering materials from its own suppliers. Howmet is now assuming Boeing will produce 20 Maxes a month for the rest of the year, down from a previous assumption of 34. It is planning to deliver lower volumes “to prevent the case where we get caught with a lot of inventory.”
