The H+S Aviation and GE Aviation Partnership

H+S Aviation is the world’s leading independent resource for CT7 / T700 service on both the turboprop and turboshaft variants of these engines. As a part of GE's authorised network, we can provide you with repairs that meet all the manufacturer's requirements.

Long known for its reliable service to the regional airline industry aboard the Saab 340, the CT7 is finding new applications in larger helicopters designed to service the offshore oil exploration industry, and we aim to match that reliability by delivering the highest standards of quality services and support. This esteemed pedigree is reflected in our capability to provide maintenance for engines on GE's ECMP program, as well as GE's appointment of our Portsmouth facility as the only location outside of the OEM that is approved for testing CT7-2E1 engines.

H+S Aviation offers extensive in-house parts repair capabilities and accessory repair and overhaul, as well as AOG, field services, and expert technical support.

Contact us whenever you need assistance with your CT7 or T700 engine.
