| Abstract Aviation regulators require maintenance organizations to mitigate against the potential catastrophic failure of redundant systems caused by Human Error. One of these mitigating strategies, “identical error”, is analysed in this paper for its efficacy at preventing Maintenance Errors. Using Rasmussen Skill-Rule-Knowledge framework (1986) in a thought experiment based scenario, and by applying a simple Human Reliability Analysis (Swain and Guttman, 1983) to the results, a potential paradox was identified; that under certain circumstances a system can intentionally produce more errors in order to result in an overall safer outcome. This finding was then considered for its real-world application to airline operators based upon the results of interview data analysed using thematic analysis (Braun & Clarke, 2006). |
