BRUSSELS, Sept 23 (Reuters) - Boeing ( BA ) has offered

remedies in a bid to secure EU approval to buy back Spirit

AeroSystems ( SPR ), the world's largest standalone

aerostructures company, according to an update on the European

Commission website.

Boeing ( BA ) announced the $4.7 billion acquisition in July last

year that would also see Airbus take on the supplier's

loss-making Europe-focused activities.

The Commission, which acts as the EU competition enforcer,

extended its decision deadline for the deal to October 14.

It is expected to seek market feedback before deciding

whether to accept Boeing's ( BA ) remedies or open a full-scale

four-month-long investigation if it has serious concerns.

The UK antitrust authority cleared the deal unconditionally

last month.
