AMAC Aerospace Completes Series of Gulfstream G450, G550 and G650 Maintenance Projects at Basel Facility
Why It MattersAs Gulfstream G650s exit manufacturer warranty, owners gain freedom to route maintenance to independent MROs, widening the competitive field beyond the OEM service network.
What happened
AMAC Aerospace carried out a series of maintenance operations on Gulfstream G450, G550 and G650 aircraft at its dedicated mid-size jet hangar in Basel, Switzerland. During the summer months, a privately owned Gulfstream G650 underwent a scheduled maintenance package along with cosmetic cabin work.
A Gulfstream G450 belonging to a head of state received landing gear replacement, an engine change, and deactivation of its EVAS (Emergency Vision Assurance System). A second privately owned Gulfstream G650 arrived on a drop-in basis for a flap roller change, while a recurrent customer's Gulfstream G550 came in for due maintenance and an annual base maintenance check.
Separately, an AMAC Aerospace team traveled to Le Bourget, France, to provide AOG support for a Gulfstream G650 owned by a head of state, rectifying the fault and returning the aircraft to service within two days. Alexis Ott, Director Sales & Key Account Management at AMAC Aerospace, said the increasing volume of Gulfstream G650 work is partly driven by those aircraft coming out of manufacturer warranty, allowing owners to select MRO providers outside the Gulfstream network.
Industry impact & what to watch
This spread of work, from scheduled base checks to a drop-in flap roller swap to an away-from-base AOG rescue, shows how a large-cabin MRO shop builds volume across a single OEM's platform rather than relying on one type of job. Head-of-state aircraft appearing alongside privately owned jets in the same hangar also points to independent providers competing for high-sensitivity government-linked fleets, not just private owners.
The segment's dynamics turn heavily on warranty status: as G650 airframes age out of Gulfstream's factory warranty, owners are freed to shop maintenance outside the OEM's own network, and Ott's comment ties that shift directly to AMAC's growing G650 workload. That is how independent MROs typically gain share on newer widebody business jets — not by underbidding the OEM network while aircraft are still under warranty, but by picking up volume once that constraint lifts.
What happens next depends on whether more G650s reach that warranty threshold and whether AOG responsiveness, demonstrated here by a two-day turnaround at Le Bourget, becomes a deciding factor for owners choosing between OEM and independent support.
