Muilenburg responds to intense questioning from the US House Transportation Committee at a hearing on the Boeing 737 Max in October 2019.
When Boeing froze the 737 Max production line, it promised not to lay off any of its own staff.
But the loss of work proved devastating for suppliers like Spirit, which said in a statement that the grounding and production freeze left them little.
“Spirit is taking this action because of the 737 MAX production suspension and ongoing uncertainty regarding the timing of when production will resume and the level of production when it does resume,” the statement said.
Spirit said it plans to lay off an unspecified number of workers at two plants in Oklahoma, and may also have to shed more workers at its Wichita base if 737 Max production does not recommence.
The laid off are due to receive 60 days’ pay, Spirit said.
