Maintenance Error Decision Aid (MEDA)

Maintenance errors have created some of the most serious flight safety events. Less accessible within our Industry are the significant costs of aircraft rework, on-time performance, lost revenue and safety reputation. MEDA is a globally recognised effective method for investigating the factors that contribute to maintenance errors. This provides a systematic process for conducting thorough and consistent investigations within the organisation, determining the factors that lead to an event and producing the recommended improvements to reduce likelihood of future incidents. This course is tailored to integrate with each company’s nature of operations and existing Safety Management and Error Management Systems.
