Final answer:
A person with a Transport Canada Civil Aviation Maintenance Engineer license and appropriate ratings can perform and certify maintenance on aircraft types they are rated for and release them back to service, however, there are limitations, such as not being able to conduct specialized repairs without additional endorsements or perform outside the scope of their training.
Step-by-step explanation:
A person holding a valid Transport Canada Civil Aviation Maintenance Engineer (AMC) license with the appropriate ratings can conduct a wide range of maintenance activities on aircraft. However, there are some limitations to what they can do.
With the appropriate ratings, they can perform and certify maintenance, preventive maintenance and any modification on the aircraft types they are rated for. This could include work on the aircraft’s structure, systems, powerplants, and avionics. They also have the authority to release the aircraft back to service after maintenance is complete, assuming all the required maintenance tasks have been performed satisfactorily and recorded correctly.
However, they cannot conduct certain specialized repairs that require additional endorsements or certifications beyond their existing ratings. They are also not authorized to perform tasks that fall outside the scope of their training or the ratings they possess. For example, they cannot certify the airworthiness of an aircraft unless they have a specific authorization known as an Aircraft Certification Authority (ACA) granted by an operator or an organization and are within the scope of their license. Furthermore, they must adhere to all regulations and standards set forth by Transport Canada during the execution of their duties.
