Final answer:
Specialized maintenance on an amateur-built aircraft can be certified by the owner or an AME under an AMO, in accordance with the Canadian Aviation Regulations.
Step-by-step explanation:
The subject of the question is related to the certification process for specialized maintenance on an amateur-built aircraft under the Canadian Aviation Regulations (CARs). According to CARs, an amateur-built aircraft may have maintenance certified by the aircraft owner, provided they comply with specific regulations and standards that apply to civilian aircraft in Canada. It is important to note that an Aircraft Maintenance Engineer (AME) can also perform and certify work on amateur-built aircraft, but they must operate under an Aircraft Maintenance Organization (AMO). The option claiming amateur-built aircraft are not subject to CARs is incorrect, as these aircraft are indeed regulated, albeit under a different set of guidelines than certified aircraft.
