Cascade Helicopter Services one of a very select few to be allowed to operate as a SAFRAN H.E. (Turbomeca) Level I and II Maintenance Center. This allows CHS to perform maintenance on certain Turbomeca engine models. Many of our customers save thousands of dollars when their engines come due overhaul. By breaking down the engine into modules to be sent in for overhaul verses sending in the entire engine, lead time and costs are reduced.
