Study on Human Factor Evaluation of Aviation Maintenance During Flight Test

摘要

Human error is one of the main factors leading to flight accidents. Previous human factor analysis in aviation maintenance mainly focused on qualitative evaluation with subjective results. Combined with the actual maintenance work during flight test, the paper proposed a comprehensive evaluation method including modified analytical hierarchy process, expert evaluation and grey relational analysis, fully considering the inevitable fuzziness and subjectivity of human factors. Then, the influence degrees of human factors on aviation maintenance were analyzed and recognized quantitatively for the specific accidents based on the huge data during flight test, and the corresponding risk management tips and other prophylactic measures were raised. Finally, this model was applied in one real test aircraft, and the results proved the validity of this study.
