PARIS, June 25 (Reuters) - Airbus is poised to

take over all or part of the operations of four Spirit

AeroSystems ( SPR ) plants as part of an impending deal that

involves a carve-up of the U.S.-based aerostructures maker with

Boeing ( BA ), industry sources said.

As expected, the two main plants involved in the transfer to

Airbus are Kinston, North Carolina, where Spirit makes a crucial

part of the A350 fuselage known as Section 15, and a historic

plant in Northern Ireland that makes carbon wings for the A220.

Additionally, Airbus is expected to absorb activities at a

plant in the aerospace cluster in Casablanca, Morocco, where

Spirit does some fuselage work for the A220 and produces some

engine nacelles or housings for the A320, they said.

Also expected to be involved is Spirit's plant in

Saint-Nazaire in western France, which receives the A350

sections built in Kinston and partially assembles them to be

sent on to Airbus in Toulouse where the wide-body jets are made.

Other Spirit plants include Wichita, Kansas, where it

carries out its main Boeing ( BA ) operations, as well as Prestwick in

Scotland, Subang in Malaysia and Tulsa, Oklahama.

Airbus and Spirit declined comment on the details of any

impending deal.
