Charleston County's Aviation Authority picked up two new female members Monday - one who was expected and one who came in as a surprise.

Former S.C. first lady Jenny Sanford was selected to be state Sen. Chip Campsen's designee appointee on the authority board.

She'll represent Campsen, R-Isle of Palms, in his role as an officer with the Charleston County legislative delegation.

When seated, Sanford will join Helen Hill on the 13-member board. She also was appointed Monday.

As executive director of the Charleston Area Convention and Visitors Bureau, Hill was a heavy favorite going in. She became a likely choice because of her involvement in helping to land low-cost carriers Southwest Airlines and JetBlue Airways at the Charleston International Airport, among other tourism accomplishments.

In a third major appointment by Charleston lawmakers Monday, estate lawyer M. Emerson "Tripp" Wiles III was selected to fill a vacancy on the Charleston County School Board.

Wiles, who lives in West Ashley, is married and has two young children who haven't reach school-attending age, he said.

Monday's aviation authority appointments came about in a form of political musical chairs. Hill would replace Michael Stavrinakis, who announced he was leaving to concentrate on his other politically appointed assignment, on the Medical University of South Carolina Board. Sanford had been a candidate for his vacancy, too.

But Campsen, a long-time Sanford friend, picked her to fill a second vacancy recently created when his other designee, Ben Hagood, announced he will step down from the authority board on Dec. 31.

Campsen doesn't think the law that placed him on the 13-member airport authority is constitutional, so he sends a designee in his place. A lawsuit challenging that law is on appeal.

Hill's nomination will be forwarded to Gov. Nikki Haley, whose office will perform a background check before she accepts or rejects the selection made by members of Charleston's House of Representative delegation.

Wiles was appointed to the school board's West Ashley post left empty when previous seat holder John Barter resigned to take a new job in Alabama. Twelve candidates had applied for that post.

Wiles' appointment was widely supported by Republicans on the delegation, rejecting an endorsement floated last week by the county GOP to support music store president Charles Fox. Fox did not appear for Monday's candidate interviews. Wiles' pick will also have to be approved by the governor.
