Responsibilities and licensing
Under Canadian federal law, the release of maintenance work performed on aircraft in Canada – especially "transport category" fixed-wing aircraft or turbine-powered helicopter aircraft must be accomplished by a person with specific training and licensing. These persons are individually licensed by the Canadian Federal Government through TC and are known as aircraft maintenance engineers or "AMEs". While the term AME is not recognized by the Provincial Engineering Associations, AMEs act on behalf of the Minister of Transport to ensure the safety of the Canadian public with regard to the work performed during maintenance of certified aircraft. The AME is not required to actually conduct the maintenance work they sign for, but must supervise non-licensed personnel or conduct inspections of the work to be signed for to the extent necessary to satisfy themselves that the work was completed correctly. Not all aircraft maintenance releases require the signature of an AME in Canada. For work on Canadian aircraft conducted outside Canada, a person licensed by another country that has a bilateral agreement with TC may sign. In the case ofRatings
The AME licence may be endorsed with one or more ratings. These are:M1
Non-turbojet aircraft, under max takeoff weight, and a passenger capacity of 19 or less.M2
All aircraft not included in M1, excluding balloons, but including all airframes, engines, propellers, components, structures and systems of those aircraft. ''Note'': Holders of either an M1 or M2 rated AME licence also have maintenance release privileges for all turbine powered helicopters and SFAR 41C aeroplanes, including their associated variants and derivatives.E
Aircraft electronic systems, including communication, pulse, navigation, auto flight, flight path computation, instruments and the electrical elements of other aircraft systems, and any structural work directly associated with the maintenance of those systemsS
Aircraft structures, including all airframe structures. Note: Holders of BOTH M1 and M2 licence also have some privileges of both the "E" and "S" licences. Some systems (AFCS, HUD, etc.) require specialized training and the licence holder must be current and familiar with the system being signed for.Balloons
Issuance
Upon request of licence issuance, applicants shall include proof of age, training, knowledge, experience and skill as follows:Age
Prior to licence issue, the applicant shall have attained the age of 21 years. As proof of age, the following documents are acceptable: * Canadian citizenship certificates; * Birth or baptismal certificates; * Passports; or * Any Federal or provincial identifying document showing the applicant's birth date. * Where proof of age cannot be provided by means of a document referred to in any of subparagraphs (i) to (iv), a declaration of age may be accepted in lieu.Training
Knowledge
Transport Canada approved training courses include technical examinations on the subjects covered by the course. Applicants shall successfully complete all the applicable examinations for the subjects concerned, conducted by the ATO in accordance with its approved procedures. As proof, the applicants shall submit a certificate or letter, issued by the ATO, attesting to the successful completion of the examinations.Experience
Applicants shall have acquired the applicable amount of total, specialty, and civil aviation maintenance experience set forth in Appendix A. As proof of experience, the applicants shall submit a personal log book or equivalent document signed by the persons responsible for the maintenance release of the work items recorded. At the time of application, the applicants shall have acquired all but six months of the required total experience. Credit toward the total aviation maintenance experience requirement shall be granted for time spent in approved basic training, in the ratio of one month's credit for each 100 hours of training, up to a maximum of: * 24 months for M or E rating applicants. * 18 months for S rating applicants. Therefore, a graduate from an ATO with a curriculum of 1800 hours, would qualify for 18 months credit. Experience requirements expressed in months are predicated upon full-time employment of 1800 working hours per year. Applicants with part-time experience acquired at a lower rate than this may convert their actual working hours to months at the rate of one month for each 150 working hours, but in no case can a higher rate of work be used to obtain more than one month's credit for each actual calendar month worked. Maintenance of military aircraft, or parts intended for installation on military aircraft, may be counted toward the total and specialty experience requirements, but not toward the civil aviation experience requirement. Maintenance of ultra-light, advanced ultra-light, amateur built, or owner maintained aircraft, does not qualify for any experience credit.Skill
Applicants shall have performed a representative selection of eligible maintenance tasks, over the full range of applicable systems and structures. These tasks must cover at least 70 percent of the items listed in Appendix B that are applicable to the rating sought and to the aircraft, systems or components for which the experience is claimed. Proof of having completed aircraft maintenance tasks shall take the form of a certification by the AME, or equivalent person who supervised the work. The certification statement shall include the date, aircraft type, registration mark, or component serial number as applicable.Validity and Recency
Validity period
Unless surrendered, suspended or cancelled, an AME licence remains valid until the date indicated on the licence. Transport Canada Advisory Circular (AC) No. 566-003 indicates that the licence is valid for ten years calculated after the applicant's last birthday. theRecency requirements
No person shall exercise the privileges of an AME licence unless, within the preceding 24 months; they have successfully completed the regulatory requirements examination, or have, for at least six months: * Performed aircraft maintenance; * Supervised the performance of maintenance, either directly or in an executive capacity; or * Provided aviation maintenance instruction within an ATO, or an approved training program in an AMO or directly supervised the delivery of such instructions. An AME who attempts the regulatory requirements examination as required by subsection 566.05(1) and fails will not be entitled to renewal until the examination has been successfully completed.Professional status
The issue of the divided loyalty that is inherent upon the Canadian AME as both a private sector work performer and a Ministerial delegated certifier, of their own work and of others', was the focus of a 1988 report, which noted that in contrast to some other countries which had done so, "...there is a need in Canada to develop our own perspectives on the phenomenon of inspection." The Aircraft Maintenance Engineers of Canada/Techniciens D'Entretien 'D'Aeronefs du Canada (AMEC/TEAC) is the professional association for AMEs at national level. AMEC/TEAC is financed by the six regional associations; Atlantic, Quebec, Ontario, Central, Western and Pacific. It changed its name in 2019 from the Canadian Federation of Aircraft Maintenance Engineers Associations, (CFAMEA). The Aircraft Maintenance Engineers qualification and license were instituted in 1920 when the Canadian Air Regulations introduced Air Engineers and Air Engineer certificates into Canadian Aeronautics law. The first AME license issued in Canada, Air Engineer License #1, was issued on the 20th of April 1920 to Mr. Robert A. McCombie by the Canadian Air Board.Twelve factors
Transport Canada identified twelve human factors (known in English as the "dirty dozen") that degrade people's ability to perform effectively and safely. They were adopted by the aviation industry in order to avoid human errors in aircraft maintenance. * Lack of communication Accurately completing the maintenance report without skipping any steps allows the next technician to start work exactly where it was finished. This is especially important when more than one technician is working on the same plane at the same time. * Complacency The technician's experience and knowledge cause him to feel overconfident and complacent, which is why routine tasks are performed without proper concentration. * Lack of knowledge The lack of specific knowledge about servicing different aircraft models can lead to catastrophic results. * Distraction It is estimated that 15 percent of maintenance related errors are caused by distractions. Distracted attention may cause the technician to lose sight of a detail that requires attention. * Lack of teamwork Since the maintenance of an aircraft involves the work of several people and even teams, the lack of communication and overall direction increases the complexity of the work, and disagreements between teams can directly affect the physical integrity of the aircraft. * Fatigue Fatigue can be both physical and mental. This factor is especially dangerous because until fatigue becomes critical, the person does not realize that he is tired, and his attentiveness is constantly reduced. * Lack of Resources Lack of quality resources may prevent the technician from performing the maintenance task in accordance with the engineering documentation. * Pressure Some companies use strict schedules to ensure that technicians do their work quickly and efficiently. In most cases, excessive pressure negatively affects the results of work. * Lack of assertiveness Assertiveness is the ability to express feelings, opinions, and needs in a positive and productive manner. The lack of this quality may cause the technician not to report a potential problem. * Stress Working in dark, closed rooms, with a lack of qualitative resources, for a long time, as well as a lot of responsibility are the main stressful factors that cause errors in service. * Lack of awareness Failure to recognize all the consequences of your actions and/or lack of foresight may cause maintenance errors. * Norms Unwritten standards and rules adopted by companies that bypass the engineering documentation. Some of them are unsafe or have a negative impact on the work of technicians.See also
