If this part is replaced hundreds of times per year, over the course of many years, then there may be an opportunity to save money by adjusting the repair process to leverage this economy of scale (reliability improvements, component repair, etc.). This analysis drives the maintenance support for each repairable unit analyzed.
The Rolls-Royce Trent 1000 is a high-bypass turbofan engine produced by Rolls-Royce, one of the two engine options for the Boeing 787 Dreamliner, competing with the General Electric GEnx. It first ran on 14 February 2006 and first flew on 18 June 2007 before a joint EASA/FAA certification on 7 August 2007 and entered service on 26 October 2011.
Metallurgical failure analysis is the process to determine the mechanism that has caused a metal component to fail. It can identify the cause of failure, providing insight into the root cause and potential solutions to prevent similar failures in the future, as well as culpability, which is important in legal cases.

The sort of faults that can be detected include a range of mechanical problems such as imbalance, misalignment, and bearing problems in the motor and driven equipment, as well as electrical problems including insulation breakdown, loose stator windings, rotor slot problems, current or voltage imbalance, and harmonic distortion.
The new components also reduced engine wear, lowering maintenance costs by about 5%. The engines entered service in 2007, and all new CFM56-5B and CFM56-7B engines are being built with the Tech Insertion components. CFMI also offers the components as an upgrade kit for existing engines. [30]

Engineering analysis is decompositional: it proceeds by separating the engineering design into the mechanisms of operation or failure, analyzing or estimating each component of the operation or failure mechanism in isolation, and re-combining the components according to basic physical principles and natural laws.
