Power by the Hour
Power-by-the-Hour is a term coined by Bristol Siddeley in the early 1960s. It was used to describe a support service provided for Viper engines in the DH125, HS125 and BH125 business jet aircraft. For a fixed sum per flying hour, a complete engine and accessory replacement service was provided, thus allowing the operator to forecast such costs with great accuracy, and thus relieving the purchaser of the need to purchase stocks of engines and accessories. In the 1980s Rolls-Royce re-invented the program, and claimed that "The key feature of the program is that it undertakes to provide the operator with a fixed engine maintenance cost over an extended period of time. Operators are assured of an accurate cost projection and avoid the costs associated with breakdowns." and is an available option for operators of several aircraft engines manufactured by Rolls-Royce plc.
Though the term "Power by the Hour" is the common name given to the described service in the industry, it is trademarked by Rolls-Royce plc. Other aircraft engine manufacturers such as General Electric and Pratt & Whitney offer similar programs. In addition to the manufacturer programs, Jet Support Services Inc. provides hourly cost maintenance programs independently.
Bombardier offers a similar program for both its Business and Commercial aircraft called Smart Services. Smart Services is a full portfolio that covers parts and maintenance for the entire aircraft on a pay-by-the-hour model.
