Which classes of aeronautical products can be returned to service using an Authorized Release Certificate?

The correct choice indicates that an Authorized Release Certificate (also known as a Form 8130-3) can be utilized for Class II and III aeronautical products. This highlights the regulatory framework that distinguishes between the classes of aeronautical products based on their complexity and the associated certification requirements.

Class II products generally include parts and equipment that are essential for the operation of aircraft but do not have the same critical safety implications as Class I products. Class III refers to products that, while still needing oversight, are usually non-critical components that are less likely to affect the overall safety of the aircraft.

The use of an Authorized Release Certificate provides a means for these classes of products to be returned to service legally, verifying that they meet the necessary standards. This ensures a level of assurance in terms of maintenance and compliance with safety regulations.

Additionally, Class I products typically require a more stringent process for release to service, often involving other specific certifications or additional oversight. This reinforces the importance of proper documentation and accountability in the maintenance and operation of aircraft, particularly for critical components.
