(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.

An Airbus spokesperson said it had "no comment on any potential support we may provide to our suppliers".
