Dulles Aviation, one of two FBOs at Washington D.C-area Manassas Regional Airport, Virginia's busiest business aviation airport, will be closing its doors permanently on Friday. A fixture at the airport for nearly half a century, the family-owned, full-service provider allowed its current short-term lease to expire after being unable to reach acceptable terms on a long-term renewal with the airport, according to company executive Tom Gardner. He noted the company’s flight school at Manassas has relocated to nearby Leesburg Executive Airport, where it will partner with existing training provider Av-Ed.

“We are thankful for the partnership and quality of service that Dulles Aviation has contributed to the Manassas Regional Airport,” said airport director Juan Rivera. “Dulles Aviation has been a catalyst in the growth and development of the airport."

While the move temporarily brings the airport to just one service provider, APP Jet Center, aircraft maintenance and management provider Chantilly Air broke ground last week on a nine-acre FBO complex, which will include 90,000 sq ft of hangar and office space, that is expected to open early next year.

An airport spokesperson said it is exploring other aviation uses for the Dulles Aviation facility, aside from FBO operations.
