Which EASA license category allows certification of Base maintenance work?

The EASA license category that allows for the certification of Base maintenance work is Category C. Base maintenance refers to the comprehensive overhaul, refurbishment, repair, and inspection of aircraft, which typically takes place at a maintenance organization’s facility. This type of maintenance is more complex and is focused on ensuring that the aircraft meets all safety and regulatory requirements before it is returned to service.

An individual holding a Category C license is authorized to issue certificates of release to service after base maintenance has been performed, which confirms that the aircraft has been properly maintained according to safety standards. This includes extensive work that may involve various systems within the aircraft, affecting overall airworthiness.

In contrast, other categories such as A, B1, and B2 have specific limitations regarding the types of maintenance they can certify. Category A, for instance, primarily covers line maintenance and is focused on quick checks and minor repairs, while Category B1 and B2 licenses cover specific aircraft systems and components. As a result, they are not equipped or authorized for the scope of work needed in base maintenance operations, thereby reinforcing the significance of the Category C license for such tasks.
