The use of SPC tools for a preliminary assessment of an aero engines' maintenance process and prioritisation of aero engines' faults

摘要

The purpose of this paper is to provide a relatively straightforward approach of implementing standard statistical process control (SPC) concepts while instituting problem-solving intonations in aero-engine maintenance processes.The inspection workflow approach is presented in order to aid in collecting and monitoring critical aero-engine data. Observed defects are categorized according to a Pareto analysis assisted by a cause-and-effect diagram. A binomial process capability analysis is performed on nonconforming aero-engines based on operating curves produced specifically for this case study. The time frame for experimental analysis is reflected in a span of six months.
