In Canada an Aircraft maintenance engineer (AME) is a person who is responsible for signing the maintenance release of certified aircraft and is licensed to do so by the national airworthiness authority, Transport Canada (TC). [1] Their job is to ensure that aircraft are maintained in a safe condition. [2]

Contents

The applicant for an AME licence must be at least 21 years old. Aircraft maintenance engineers must complete a training course at a TC approved training organization (ATO), which are mostly Canadian vocational colleges. There are also approved distance learning courses. A period of apprenticeship prior to writing the licensing examinations is required. Upon successful completion they are granted an AME licence, which is valid for six years and may be renewed. [1]

AMEs retain their recency by completing maintenance or related work. The Canadian Aviation Regulations require that once the holder's licence is more than two years old that they complete six months worth of work in the previous two years performing or supervising aircraft maintenance, act in an executive capacity in a maintenance organization, or teach or supervise teaching of aviation maintenance at an approved training organization. [3]

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. [1]

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 of amateur-built aircraft the owner may sign and for owner-maintenance category aircraft the owner may sign if they are also a licensed pilot. In Canada ultralight aircraft, hang gliders and paragliders as well as model aircraft do not require signatures for release to return to flight. In the case of aircraft parts maintained on the bench (i.e. while removed from the aircraft) persons authorized by an Approved Maintenance Organization (AMO) may also sign the release, whether they hold an AME licence or not. But the maintenance release for the subsequent installation of such parts into an aircraft may only be made by the holder of an AME licence. [4]

Canada has no legal system that requires the person who performs aircraft maintenance to hold a licence. Canada requires that the person who certifies the work has inspected it for accuracy and correct completion. The Canadian AME licence allows the holder to both perform AND to certify their own maintenance work, or to certify the maintenance work performed by an unlicensed person. This type of licence is unlike the system used in the United States of America, whereby the FAA issues licences to persons who perform maintenance work on aircraft as technicians by way of "ratings" (the "airframe" or "powerplant" rating or the combined "airframe and powerplant" rating) and a separate licence to accomplish the "Inspection" certification – the I.A certificate. The US has focused on "the performance of work", while Canada and the other Commonwealth countries make a distinction between actually working on the machines and inspecting them for safety.[ citation needed ]

Ratings

The AME licence may be endorsed with one or more ratings. [1] These are:

M1

Non-turbojet aircraft, under 19,000 lb (8,618 kg) 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. [1]

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 systems [1]

S

Aircraft structures, including all airframe structures. [1]

Note: Holders of BOTH M1 and M2 licence also have some privileges of both the "E" and "S" licences. [1] Some systems (AFCS, HUD, etc.) require specialized training and the licence holder must be current and familiar with the system being signed for.[ citation needed ]

Issuance

Upon request of licence issuance, applicants shall include proof of age, training, knowledge, experience and skill as follows: [1]

Age

Prior to licence issue, the applicant shall have attained the age of 21 years. [1] 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

Applicable training may be obtained by means of distance learning courses or traditional college. In any case, the organization has to be approved by Transport Canada. [1]

With some exceptions, an applicant shall successfully complete basic training applicable to the rating. As proof of training, the applicant shall provide a certificate of successful completion of an acceptable aircraft maintenance training course. Where the applicant is seeking experience credit for the training, the certificate shall be issued by an Approved Training Organizations (ATO). [1]

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. [1]

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. [1]

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. [1]

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. [1]

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. [1]

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. [1]

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. As of June 2021 the Canadian Aviation Regulations still indicate a six-year validity period. [1] [5]

Recency 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: [1]

  • 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. [1]

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." [6]

The Aircraft Maintenance Engineers of Canada (AMEC/TEAC) is the professional association for AMEs at national level. [7] 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). [8]

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. [9] They were adopted by the aviation industry in order to avoid human errors in aircraft maintenance.[ citation needed ]

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.

The technician's experience and knowledge cause him to feel overconfident and complacent, which is why routine tasks are performed without proper concentration.

The lack of specific knowledge about servicing different aircraft models can lead to catastrophic results.

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.

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 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 quality resources may prevent the technician from performing the maintenance task in accordance with the engineering documentation.

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.

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.

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.

Failure to recognize all the consequences of your actions and/or lack of foresight may cause maintenance errors.

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.

Private pilot licence Type of pilot license

A private pilot licence (PPL) or, in the United States, a private pilot certificate, is a type of pilot licence that allows the holder to act as pilot in command of an aircraft privately. The licence requirements are determined by the International Civil Aviation Organisation (ICAO), but implementation varies widely from country to country. According to the ICAO, it is obtained by successfully completing a course with at least 40 hours of flight time, passing seven written exams, completing a solo cross-country flight, and successfully demonstrating flying skills to an examiner during a flight test. In the United States, pilots can be trained under Part 141 of Title 14 of the Code of Federal Regulations, which allows them to apply for their certificate after as few as 35 hours. However, most pilots require 60–70 hours of flight time to complete their training. The minimum age for a student pilot certificate is 14 for balloons and gliders and 16 for powered flight. The minimum age for a private pilot certificate is 16 for balloons and gliders, and 17 for powered flight. Pilots can begin training at any age and can solo balloons and gliders from age 14 and powered aircraft from age 16.

The airline transport pilot license (ATPL), or in the United States of America, an airline transport pilot (ATP) certificate is the highest level of aircraft pilot certificate. In the United States, those certified as airline transport pilots (unconditional) are authorized to act as pilot in command on scheduled air carriers' aircraft under CFR 14 Part 121. In the UK, pilots must hold an ATPL before they can be pilot in command on an aircraft with 9 or more passenger seats.

A commercial pilot licence (CPL) is a type of pilot licence that permits the holder to act as a pilot of an aircraft and be paid for his/her work.

Aircraft maintenance technician

In the US, an aircraft maintenance technician (AMT) is a tradesperson and also refers to a licensed technical qualification for carrying out aircraft maintenance. AMTs inspect and perform or supervise maintenance, preventive maintenance, repairs and alteration of aircraft and aircraft systems.

Pilot licensing or certification refers to permits for operating aircraft. They are issued by the Civil Aviation Authority (CAA) in each country, establishing that the holder has met a specific set of knowledge and experience requirements. This includes taking a flying test. The certified pilot can then exercise a specific set of privileges in that nation's airspace. Despite attempts to harmonize the requirements between nations, the differences in certification practices and standards from place to place serve to limit full international validity of the national qualifications. In addition, U.S. pilots are certified, not licensed, although the word license is still commonly used informally. Legally, pilot certificates can be revoked by administrative action, whereas licensing requires intervention by the judiciary system.

Pilot certification in the United States Pilot certification

Pilot certification in the United States is typically required for an individual to act as a pilot-in-command of an aircraft. It is regulated by the Federal Aviation Administration (FAA), a branch of the U.S. Department of Transportation (USDOT). A pilot may be certified under 14 Code of Federal Regulations (CFR) Part 61 or 14 CFR Part 141. Pilots may also be certified under 14 CFR Part 107 for commercial drone operations.

A type certificate signifies the airworthiness of a particular category of aircraft, according to its manufacturing design. It confirms that the aircraft of a new type intended for serial production, is in compliance with applicable airworthiness requirements established by the national air law.

Flight instructor Person who teaches others to operate aircraft

A flight instructor is a person who teaches others to operate aircraft. Specific privileges granted to holders of a flight instructor qualification vary from country to country, but very generally, a flight instructor serves to enhance or evaluate the knowledge and skill level of an aviator in pursuit of a higher pilot's license, certificate or rating.

A parachute rigger is a person who is trained or licensed to pack, maintain or repair parachutes. A rigger is required to understand fabrics, hardware, webbing, regulations, sewing, packing, and other aspects related to the building, packing, repair, and maintenance of parachutes.

Ultralight aircraft (Canada)

The Canadian Aviation Regulations define two types of ultralight aircraft: basic ultra-light aeroplane (BULA), and advanced ultra-light aeroplane (AULA).

A safety pilot is a rated pilot who helps maintain visual separation from other aircraft, clouds, and terrain while another pilot is wearing view limiting devices for the purposes of simulating instrument conditions.

Airworthiness Measure of an aircrafts suitability for safe flight

In aviation, airworthiness is the measure of an aircraft's suitability for safe flight. Initial airworthiness is demonstrated by a certificate of airworthiness issued by the civil aviation authority in the state in which the aircraft is registered, and continuing airworthiness is achieved by performing the required maintenance actions.

Type rating Certification of an airplane pilot to fly a certain type of aircraft

A type rating is an authorization entered on or associated with a pilot licence and forming part thereof, stating pilot's privileges or limitations pertaining to certain aircraft type. Such qualification requires additional training beyond the scope of the initial license and aircraft class training.

Aircraft maintenance Performance of tasks which maintain an aircrafts airworthiness

Aircraft maintenance is the performance of tasks required to ensure the continuing airworthiness of an aircraft or aircraft part, including overhaul, inspection, replacement, defect rectification, and the embodiment of modifications, compliance with airworthiness directives and repair.

An ordinary seaman (OS) is a member of the deck department of a ship. The position is an apprenticeship to become an able seaman, and has been for centuries. In modern times, an OS is required to work on a ship for a specific amount of time, gaining what is referred to as "sea time". For centuries, the term ordinary seaman was used to refer to a seaman with between one and two years' experience at sea, who showed enough seamanship to be so rated by their captain. Historically in some navies and the merchant marine a sailor with less experience was called a landsman.

Air operators certificate Approval by civil aviation authorities to operate aircraft for commercial purposes

An air operator's certificate (AOC) is the approval granted by a civil aviation authority (CAA) to an aircraft operator to allow it to use aircraft for commercial purposes. This requires the operator to have personnel, assets, and system in place to ensure the safety of its employees, and the general public. The certificate will list the aircraft types, and registrations to be used, for what purpose and in what area – specific airports or geographic region.

In the United States, there are three classes of medical certifications for pilots; such certificates are required to legally exercise the privileges of a Pilot exercising the privileges of either a Private, Commercial, or Airline Transport Pilot license. Medical Certificates are not needed for Glider, Balloon, Recreational, or Sport Pilot certifications. Each certificate must be issued by a doctor approved by the Federal Aviation Administration to a person of stable physical and mental health.

An Aircraft Maintenance Engineer (AME), also Licensed Aircraft Maintenance Engineer, is a licensed person who carries out and certifies aircraft maintenance. The license is widespread internationally and is recognised by the International Civil Aviation Organization (ICAO). The American FAA recognise the qualification in foreign countries but refers to it as aviation maintenance engineer rather than "Aircraft...". Unlicensed mechanics or tradespersons are sometimes informally referred to as "Unlicensed AMEs"
