Title of Paper:Residual Risk Assessment of Civil Aircraft for Airworthiness Requirements

Journal:Lect. Notes Electr. Eng.

Abstract:In this paper, to evaluate the acceptability of candidate corrective actions and monitor the risk variation during civil aircraft operation, the process of determining residual risk has been established including current risk level, acceptable degree, time limit of candidate actions, and optimal corrective actions. There are two crucial key points, that is, risk assessment and candidate actions. Risk assessment can be obtained through probabilistic damage tolerance (PDT) or Monte Carlo simulation (MC), of which PDT including occurrence probability, size distribution, stress uncertainty and detection probability, MC including risk levels, flight conditions, and risk factors. Candidate actions include regular maintenance or replacement, maintenance by fixed interval or service age, change the maintenance cycle, and redesign or refit, etc. Compared with the risk guidelines of civil aircraft, the priority of candidate corrective action will be decided to optimize the maintenance processes. The risk in decision making can be formulated by the residual risk to enhance the civil aircraft safety. © 2019, Springer Nature Singapore Pte Ltd.
