Spirit AeroSystems now plans to resume normal operations by 23 April at the Wichita, Kansas, production complex, or 10 days after tornado-force winds damaged at least the exteriors of multiple buildings.
Most of the structures supplier's employees remain idled with pay this week while recovery crews attempt to restore power systems, clear debris and make the facility safe again for workers.
Resuming production by 23 April is the company's "goal", according to a note to employees posted late today. Afterward, the company would "work on ramping back up to full-rate production".
Spirit AeroSystems' Wichita facility is a key supplier to Boeing, shipping the entire fuselage of the 737, as well as major sections of the 787, 747 and 777.
Pictures released by the company on 17 April showed that the interior of the 737 assembly facility was completely intact, including other production tooling. Other damages showed extensive damage to exteriors of several buildings. The site also access to critical power, gas and water systems for several days because of the storm.
On 17 April, company officials said they intend to complete some shipments by the end of this week.
