Airbus is poised to finalise an agreement as early as Wednesday with struggling aerospace supplier Spirit Aerosystems on fresh funding and revised payment terms, a person familiar with the matter said.

Hours after announcing it will receive up to $350 million in advance payments from Boeing, Spirit said it has an updated memorandum of agreement with Airbus stating the European aerospace giant will provide the major supplier with a $107 million non-interest-bearing line of credit.

Boeing has agreed to pay Spirit AeroSystems up to $350 million in advance to keep producing products for it as the fuselage supplier works through a liquidity crunch. The jet maker said Tuesday that the advance payments are intended to help Spirit address high levels of inventory and lower operational cash flows.
