Williams International appointed Constant Aviation’s Las Vegas facility as an FJ44-3AP authorized service center. It allows Constant Aviation to offer Nextant 400XT operators in-house engine maintenance, on-site parts and warranty claim processing. Similar approvals for the company’s Cleveland and Birmingham, Ala. facilities are pending. A Nextant 400XT authorized service center since late 2011, the MRO has completed more than 15 scheduled inspections. “We are excited to become a Williams International FJ44-3AP authorized service center,” said Kevin Dillon, the MRO’s vice president of operations.
