Gulfstream APU shops perform all facets of APU maintenance and repair.

Staffed by a team of experienced, factory-trained professionals, Gulfstream APU shops perform all facets of APU maintenance and repair. Turn time is second to none with a current average of nine days as opposed to the industry median of approximately 35. Also, as a mixed-fleet operator, you will experience the benefits of Honeywell’s authorization of heavy repairs by Gulfstream’s APU shop for almost two dozen variants of the popular 36-100, 36-150, RE-100 and RE-220 engines.

In addition to the benefits of a superior mechanical staff, the APU shop is also uniquely positioned as a fully authorized Honeywell Maintenance Service Plan (MSP), Honeywell warranty and Jet Support Services (JSSI) administrator. You will be kept up to date by our transparent processes and will feel confident knowing your investment is being handled by a team of experts. From routine transactions to the more complex, Gulfstream can guide you every step of the way.

One especially crucial element that sets Gulfstream’s APU shops apart from the rest of the industry, aside from superior quality and turn time, is the Gulfstream-owned rental bank. Another significant investment by Gulfstream to ensure operator dispatch ability, the APU rental bank is maintained to the same exacting standards as all other engines serviced by Gulfstream. To get you through significant periods of operational commitments, Gulfstream’s rental engines are proof of our commitment to you as a Gulfstream customer.
