DunnAir Business Jet Completion Center has received its repair station certificate from the FAA. The Tucson, Ariz.-based company at Tucson International Airport already has 44 employees and expects to have 150 on the payroll by this time next year. The facility is located in a 235,000-sq-ft hangar capable of simultaneously holding as many as four Boeing 747s, making it the largest completion and refurbishment center in the U.S. In fact, the exterior paint bay alone could–“in a squeeze”–accommodate a 747, according to founder, president and CEO Dale Dunn. “We could easily fit in a 767.” The company, said Dunn, got its permit to do exterior paint on July 29, “the same day we got the repair station certificate."
