In February of 2015, Ameco signed an engine Power-by-the-Hour (PBH) contract with Shanghai Airlines, a wholly owned subsidiary of China Eastern Airlines. Based on the contract, Ameco will provide engine overhaul, repair and other value-added services on 14 PW4000s from six Boeing 767s of Shanghai Airlines. This is the first time for Ameco to provide engine services under a PBH model. Under an engine PBH service model, the MRO suppliers will charge the airlines based on engine flight hours and other indexes. In comparison to a single charge business model, the flat rate of the PBH is beneficial for airlines to stabilize their maintenance costs and let them focus on their core business. Ameco is capable of providing PW4000 and RB211 engine overhaul. It is also developing overhaul capability on a new engine type.
