APP Jet Center has broken ground on a new 20,000-sq-ft heated hangar at its Manassas Regional Airport facility near Washington, D.C. When completed in January, the FBO’s sixth hangar will be able to accommodate business aircraft up to the size of a Gulfstream G650. The addition will bring the total aircraft storage space at the facility to 150,000 sq ft. APP’s existing hangar space at Manassas is fully occupied, and the company said it continues to receive inquiries from operators based at Dulles seeking to relocate there.
