A light-sport aircraft, also known as light sport aircraft or LSA, is a small aircraft that is simple to fly and which meets certain regulations set by a National aviation authority restricting weight and performance. For example, in Australia the Civil Aviation Safety Authority defines a light-sport aircraft as a heavier-than-air or lighter-than-air craft, other than a helicopter, with a maximum gross takeoff weight of not more than 560 kilograms (1,200 lb) for lighter-than-air craft; 600 kilograms (1,300 lb) for heavier-than-air craft not intended for operation on water; or 650 kilograms (1,400 lb) for aircraft intended for operation on water. It must have a maximum stall speed of 45 knots (83 km/h; 52 mph) in landing configuration; a maximum of two seats; a maximum speed in level flight with maximum continuous power (Vh)—138 mph (120 knots) CAS; fixed undercarriage (except for amphibious aircraft which may have repositionable gear, and gliders which may have retractable gear); an unpressurized cabin; and a single non-turbine engine driving a propeller if it is a powered aircraft.
In the US, several distinct groups of aircraft may be flown as light-sport. Existing certificated aircraft and experimental, amateur-built aircraft that fall within the definition listed in 14CFR1.1 are acceptable, as are aircraft built to an industry consensus standard rather than FAA airworthiness requirements. The accepted consensus standard is defined by ASTM Technical Committee F37. Aircraft built to the consensus standard may be factory-built and sold with a special airworthiness certification (S-LSA) or may be assembled from a kit under the experimental rules (E-LSA) under experimental airworthiness. A company must have produced and certified at least one S-LSA in order to be permitted to sell E-LSA kits of the same model. E-LSA kits are not subject to the normal experimental amateur built (E-AB) requirement 14CFR21.191 which identifies an aircraft, the "major portion of which has been fabricated and assembled by persons who undertook the construction project solely for their own education or recreation."
Aircraft which qualify as LSA may be operated by holders of a sport pilot certificate, whether they are registered as light sport aircraft or not. Pilots with a private, recreational, or higher pilot certificate may also fly LSA, even if their medical certificates have expired, so long as they have a valid driver's license to prove that they are in good enough health to fly and their medical certificate has not been denied or revoked. LSA also have less restrictive maintenance requirements and may be maintained and inspected by traditionally certificated Aircraft Maintenance Technicians, by individuals holding a Repairman: Light Sport certificate, and (in some cases) by their pilots and/or owners.
