Depending on condition, your engine then follows a rigorous process which entails, but is not limited to, work scope, disassembly, cleaning, module assembly, testing, and final inspection. Heli-One’s processes have been designed around lean principals in order to reduce cost and TAT, getting your engine back in service quickly.

CT58 Engine Capability

CT58 ER-7 Compressor Blade Spray

Heli-One, in conjunction with MDS Coating Technologies (MCT), and AeroTech Engineering Consultants, has developed an FAA Approved Repair for the application of MCT’s ER-7 erosion resistant coating on GE’s CT58 engines that extends engine Time-on-Wing (TOW) and improves safety-of-flight in erosive environments. This coating prevents blade erosion from airborne particles in desert operations and has proven to improve: engine efficiency, TOW, safety, and lower scrap rates.
