Bombardier has closed its green completion center in Tucson, but it is still doing business aircraft interior refurbishment at its adjacent Tucson Service Center. In December, Bombardier and the Tucson Airport Authority reached a new lease agreement that allows start-up completion center DunnAir to gradually take possession of Bombardier’s former completion facility (see page 76). Meanwhile, Bombardier will finish a number of active projects there and fully vacate the building in May. At the service center, which provides maintenance for Bombardier’s regional jets, the company is continuing to do interior refurbishment work on its Challenger, Global Express and Learjet lines, provide full exterior paint, and issue STCs for business jet modifications.
