Airbus plans to bolster its business with aerospace suppliers in Southern California as part of a strategy to double its annual $12 billion spending with U.S.-based manufacturers.

The European airframer, which is developing a final assembly line for the A320 family in Mobile, Ala., currently places work worth more than $1 billion a year in Southern California. Announcing plans to build new partnerships at an Oct. 19 summit meeting attended by more than 100 locally based suppliers in Los Angeles, Airbus Americas Chairman Allan McArtor said, “Hundreds of thousands of jobs are supported through Airbus’s partnership with the U.S., and with our commitment to expand, we believe those numbers will increase in the coming years.”

The meeting included briefings for suppliers on Airbus’s growth plans, including sales projections, manufacturing needs and procurement strategy. It also included presentations from existing suppliers, such as Alcoa, Parker Hannifin, Honeywell and AMI Metals. Also presenting was Aerospace Dynamics International, which last week broke ground on a new building in Santa Clarita, Calif., to manufacture landing gear beams and under-wing fittings for the A350.

Airbus, which in 2011 placed more than $12 billion worth of business for parts, components, tooling and other services from more than 400 U.S. suppliers in more than 40 states, expects to deliver the first U.S.-assembled A320 in 2016.
