Analysis and management of aviation maintenance errors

Maintenance error has been the most important causal factors in aviation accidents. Classification and analysis of maintenance errors are conductive to flight safety. This article analyzed the changes of aviation maintenance environment, and developed a maintenance error classification and analysis framework based on Reason’s model which includes unsafe acts, preconditions for unsafe acts, unsafe supervision, and organizational influences. The framework was further subdivided according to maintenance practice. The paper also briefly introduced several error management techniques applied in maintenance field, and addressed that it was necessary to code a detailed error classification and analysis system by means of the framework.
