Aircraft maintenance involves the repair, inspection, and overhaul of an aircraft and/or its components. Maintenance typically includes installation or removal of components from an aircraft, as well as ensuring compliance with state and federal regulations. Airplane maintenance does not include work such as the replacement of tires, spark plugs and inspection plates. Aircraft maintenance technology also does not include aircraft service such as refueling and washing. Work that is done as part of the original manufacturing of the aircraft is not considered in airplane service and therefore does not reflect in aircraft maintenance cost. |

All aircraft must carry a valid Certificate of Airworthiness in order to legally fly. This certificate can only remain valid if the aircraft in question is regularly maintained by an Aircraft Maintenance Engineer (AME). AMEs must adhere to local, federal and international aviation standards to certify any aircraft. AMEs must repair defects reported by pilots or aircraft personnel before an aircraft can be re-certified. Amateur-built aircraft can be inspected by the owner or builder of the aircraft instead of a licensed engineer, as these craft adhere to different regulations and laws. Because of periodic audits carried out by local aviation authorities, AMEs carry a considerable legal responsibility for every craft they inspect.

| Both airplanes and helicopters must be certified in a similar fashion. One of three certificates may be issued: A Certificate of Airworthiness, A Type Certificate or a Supplemental Type Certificate. Type Certificates (TCs) and Supplemental Type Certificates (STCs) are issued to a specific part or product modification of an aircraft. TCs are typically issued for airframes, engines and propellers. STCs are reserved for product modifications and describe how the modification affects the original design. STCs are crucial for aircraft owners, as they evaluate what further modifications may be necessary upon an aircraft. These certificates may be issued during individual part checks such as aircraft engine maintenance checks or general performance aircraft maintenance. |

According to the USA FAA, an ultralight aircraft (or ultralight airplane) is a single seat vehicle with fewer than 5 gallons of fuel capacity and a top speed of 55 knots. Restrictions and regulations regarding ultralights (which can include paragliders, hang-gliders, hot air balloons, etc.) are far more specific than other aircraft regulations and include flying only during daylight hours and over unpopulated areas. Ultralights are not permitted to exceed 255 pounds, although external landing gear (specifically amphibious) or parachute systems are not accounted for in this weight. In the United States, no license or training is required to operate ultralights, and standards are outlined by the United States Ultralight Association. |

Much of what helicopter maintenance is needed relates to the engine or rotor systems. Some older helicopters still use powerful automobile engines and radial engines for power, but most helicopters operate under a turbine engine system. Turboshafts can be altered depending on the size and type of helicopter in which it will be housed, and allow a large amount of power with very little added weight to the vehicle. Some helicopters have specific jet engines that drive the rotor. The rotor system in a helicopter generates lift and can be mounted horizontally, as most rotors are, or vertically, as a tail rotor. There are three basic classifications of helicopter rotor systems (rigid, semirigid, and fully articulated) although they all require the same general helicopter service. |
