Quantitative Evaluation Method for Aircraft Maintainability

Maintainability test and evaluation is of great significance to improve aircraft maintenance efficiency and support level. However, at present, maintainability evaluation involves many qualitative measurement indicators such as accessibility, interchangeability, maintenance human quality engineering, error prevention and maintenance safety. However, qualitative indicators rely too much on human experience, resulting in great subjective differences and difficult to form systematic and objective comments. Aiming at this problem, this paper designs a maintainability verification form, which comprehensively represents the importance of the problem by using the frequency and impact of the problem, so as to reduce the human subjectivity.
