Abstract
It is an important link to verify and determine the candidate items of the preliminary master minimum equipment list（PMMEL）for the main civil aircraft manufacturer passing through airworthiness certification. In this paper a new PMMEL fuzzy comprehensive evaluation method of civil aircraft is proposed. Firstly，the factors do⁃ main of fuzzy comprehensive evaluation is established by analyzing the purpose of PMMEL. Then，the different fuzzy weights by using the analytic hierarchy process are determined and a fuzzy comprehensive evaluation model of PMMEL is set up. The fuzzy comprehensive evaluation results are obtained. Finally，a PMMEL candidate project of the civil aircraft main landing gear down lock spring is taken as an example. Result shows that the new PMMEL evaluation method combined with the expert-based evaluation and essential fuzzy analysis is feasible and accurate，which can accurately get the clear result of whether the candidate project is allowed to be included in PMMEL and provide the analysis result verification for the traditional PMMEL method. It has important value and bright pros⁃ pects for application.
