Human Error Assessment and Reduction Technique in Aircraft Maintenance

Aircraft maintenance technician (AMT) is the most essential part of the maintenance system that ensures the aircraft to fly for many years by performing the necessary maintenance. The slightest mistake made by the technician while performing tasks in aircraft maintenance causes serious risk in flight safety. For this reason, it is very important to identify the mistakes AMT will make and develop suggestions to prevent or correct these errors. With this study, it is aimed to present a solution for determining the human errors probability (HEP) with the human error evaluation and reduction method (HEART). The HEART approach is given in an application example in critical aircraft maintenance.
