Mr. Boshears said he plans to step down after serving the airport since March 1997.
"I turned 65 this past summer in June. I just felt like it's time to retire," Mr. Boshears said.
The 12-member General Aviation Commission, which oversees the operation of the airport, is beginning the process of finding a manager to replace Mr. Boshears.
In addition to his years of running the airport, Mr. Boshears is no stranger to the cockpit. He served active duty as a fighter pilot in the Air Force from 1967 to 1973, and stayed in the Air Force Reserve until 1996.
Mr. Boshears comes from a family of aviators. His father, Willis M. "Buster" Boshears Sr., and uncle, Forrest Boshears, were instrumental in the growth of aviation in the Central Savannah River Area.
Mr. Boshears' last day will be Jan. 1. He left his post as executive director of Augusta Regional Airport in February 2008.
