COLUMBIA, S.C. (AP) - South Carolina legislators have approved an economic incentive package believed to be tailored to lure a Boeing Co. assembly plant to the state.

The approval Wednesday came at the end of a two-day session that also gave a nod to a bill that would extend jobless benefits for some state residents. Both measures head to Republican Gov. Mark Sanford.

The incentive package would allow lawmakers to guarantee tax breaks and low-interest loans for an unidentified economic development prospect.

The prospect is widely expected to be Chicago-based airplane maker Boeing Co. because it includes tax breaks on aviation fuel for test flights. The company is deciding between Everett, Wash., and North Charleston, S.C., for a mammoth plant to assemble 787 airliners.
