Duncan Completes 144-Month Inspections on Two G650s

Duncan Aviation completed 144-month inspections simultaneously on two Gulfstream G650s at its Lincoln, Nebraska, and Provo, Utah facilities. This inspection is among the most comprehensive maintenance events in an aircraft’s life cycle, involving the removal of all exterior access panels, the complete interior, and landing gear to provide full access for nose-to-tail evaluation. Many operators combine the inspection with upgrades such as interior refurbishments and exterior paint.

Matthew Benns, director of maintenance at MB Aviation Services, had a G650 inspected at Provo, and said the communication was professional and client-focused. “The level of client interaction was excellent—among the best I have seen at any MRO,” Benns said. “I felt that my priorities as a client were genuinely listened to and understood.”

Lee Noble, accountable manager of Sybajet, combined the Lincoln inspection with exterior paint work. “Rather than make the trip from the United Arab Emirates twice and have the aircraft down longer than necessary, we decided to perform the inspection here at the same time,” Noble said.

All three Duncan Aviation MROs in Michigan, Utah, and Nebraska are equipped to support the G650 with specialized tooling and factory-trained technicians, the company said.
