In an Approved Maintenance Organization (AMO), who issues or approves the maintenance release of return to service?

In an Approved Maintenance Organization (AMO), the maintenance release of return to service must be issued or approved by an authorized representative of the AMO. An authorized representative is typically an individual who has been designated by the organization to have the requisite training, qualifications, and authority to ensure that all maintenance work meets regulatory standards and that the aircraft is safe for operation.

This person's approval is critical because it signifies that a thorough inspection and maintenance process has been carried out and that all regulatory compliance checks have been addressed. They are responsible for upholding safety standards and ensuring that any maintenance performed aligns with legal and organizational requirements, thereby protecting the integrity of both the aircraft and its operational capabilities.

In contrast, other roles within the AMO, such as the owner or general maintenance personnel, may not have the necessary certification or delegated authority to issue a maintenance release. Similarly, allowing anyone from the AMO to approve such a crucial document could lead to inconsistencies and potential safety risks. The structured requirement for authorization helps maintain strict compliance with aviation safety regulations.
