Nov 12 (Reuters) - Airbus is poised to finalise

an agreement as early as Wednesday with struggling aerospace

supplier Spirit Aerosystems ( SPR ) on fresh funding and revised

payment terms, a person familiar with the matter said.

Spirit Aero, which said last week it was negotiating

possible advances from its customers, did not immediately

respond to a request for comment. The company announced earlier

it had reached a deal for new advances from Boeing ( BA ).

An Airbus spokesperson said it had "no comment on any

potential support we may provide to our suppliers".
