Which document will indicate compliance with requirements but is not mandatory?

The document that indicates compliance with requirements but is not mandatory is the Acceptable Means of Compliance. This type of document provides guidance on how to meet specific regulations or standards. It shows that an entity has approached compliance in a way that is considered acceptable by the regulatory authority, although following this guidance is not required.

In many cases, businesses can demonstrate compliance through alternative methods or practices. This flexibility allows for innovation and adaptation while still maintaining adherence to safety and operational standards. The Acceptable Means of Compliance is typically issued by regulatory bodies and serves to communicate preferred practices without imposing a binding obligation.

In contrast, the other options such as the Certificate of Compliance, Certificate of Airworthiness, and Acceptable Means of Airworthiness typically denote mandatory compliance or certifications with specific regulatory requirements. These documents are usually required to legally affirm that equipment, processes, or systems meet essential safety or operational criteria as specified by governing authorities.
