Maintenance Errors: Understand, Identify, and Manage


Human factors are by far the largest cause of failures and incidents in maintenance. This goes not only for branches like aviation but also for chemicals, oil & gas, energy, and transportation. Investigation shows that approximately 12% of all aviation accidents are caused by a maintenance factor. At coal-fired power stations, 56% of forced outages happen within a week after a planned or maintenance shutdown. A power distribution company reported that on average between 50 and 60% of all failures are related to a maintenance error.

In the past, we faced serious and tragic accidents in various branches. Maintenance errors at least contributed to all of the above mentioned major accidents. Because we are heavily dependent on complex modern technologies with high speed and large power and volumes, maintenance errors can have serious consequences in terms of safety, environmental issues, downtime, and costs. Considering the numbers and consequences, maintenance errors should be treated as a business risk. We cannot eliminate the risk of maintenance error, but we can manage it more effectively.

This course introduces participants to the skills and knowledge area of maintenance errors. It demonstrates why people make mistakes, not only in executing a maintenance job, but also in planning & preparing the job, in writing the maintenance manual and in engineering the asset. It shows how we could learn of maintenance errors, by analyzing technical failures and incidents in a structured way. And this course demonstrates how we could manage maintenance error by managing the person, the task and the team; the workplace and the organization; and by creating a safety culture
