Final answer:
An Approved Maintenance Organization must appoint a Person Responsible for Maintenance to be in compliance with aviation regulatory standards. This role ensures that all maintenance activities follow operational, safety, and regulatory demands. Other key roles include a quality assurance manager and a maintenance manager.
Step-by-step explanation:
The question pertains to the roles within an Approved Maintenance Organization (AMO) and which position must be appointed for compliance. An AMO must appoint a Person Responsible for Maintenance (PRM). The PRM is a mandatory position according to aviation regulatory standards, such as those set by the EASA or FAA in different jurisdictions. This role is akin to a director of maintenance in some respects, but terminology and specific responsibilities can vary by region and regulatory body.
While not directly mentioned in the question, other necessary roles in similar contexts include a quality assurance manager, responsible for maintaining the quality of the maintenance processes, a maintenance manager, who may oversee the daily operations, and various technical positions. These positions, like the technical director, costume shop manager, and master electrician mentioned in the reference information, each have their distinct roles but serve the wider objective of ensuring that the operational, safety, and regulatory requirements are met effectively.
