In Canada, maintenance includes the installation or removal of a component from an aircraft or aircraft subassembly, but does not include:
- Elementary work, such as removing and replacing tires, inspection plates, spark plugs, checking cylinder compression etc., on small privately operated aircraft ; or removal and replacement of fuses, light bulbs etc., on transport category aircraft .
- Servicing, such as refueling, washing windows.
- Any work done on an aircraft or aircraft component as part of the manufacturing process, prior to issue of a certificate of airworthiness or other certification document.
Aircraft maintenance is highly regulated. There are various airworthiness authorities around the world. The major airworthiness authorities include:
- Agência Nacional de Aviação Civil (ANAC) Brazil
- Civil Aviation Administration of China (CAAC) China
- Civil Aviation Authority (United Kingdom) (CAA)
- Civil Aviation Safety Authority (CASA) Australia
- Directorate General of Civil Aviation (India) (DGCA) India
- European Aviation Safety Agency (EASA) Europe
- Federal Aviation Administration (FAA) United States
- Transport Canada (TC) Canada
At the completion of any maintenance task a person authorized by the national airworthiness authority signs a release stating that maintenance has been performed in accordance with the applicable airworthiness requirements. In the case of a certified aircraft this may be an Aircraft Maintenance Engineer or Aircraft Maintenance Technician, while for amateur-built aircraft this may be the owner or builder of the aircraft.
