Category of lightweight aircraft that are simple to fly From Wikipedia, the free encyclopedia
A light-sport aircraft (LSA), or light sport aircraft, is a category of small, lightweight aircraft that are simple to fly. LSAs tend to be heavier and more sophisticated than ultralight (aka "microlight") aircraft, but LSA restrictions on weight and performance separates the category from established GA aircraft. There is no standard worldwide description of an LSA.
The civil aviation authorities in different countries have their own particular specifications and regulations which define the LSA category.
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 kg (1,235 lb) for lighter-than-air craft; 600 kg (1,323 lb) for heavier-than-air craft not intended for operation on water; or 650 kg (1,433 lb) for aircraft intended for operation on water.[1] It must have a maximum stall speed of 45 knots (83 km/h; 52 mph) in landing configuration; a maximum of two seats; there is no limit on maximum speed unless it is a glider, which is limited to Vne 135 kn 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.[1]
In the United States, several distinct groups of aircraft may be flown as light-sport.[2] Existing certificated aircraft and experimental, amateur-built aircraft that fall within the definition listed in 14CFR1.1[3] are acceptable, as are aircraft built to an industry consensus standard rather than FAA airworthiness requirements. The accepted consensus standard is defined by ASTM International Technical Committee F37.[4] 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 14 CFR 21.191[5] 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."
The FAA defines a light sport aircraft as an aircraft, other than a helicopter or powered lift, that since its original certification, has continued to meet the following:[6]

Several different kinds of aircraft may be certificated as LSA. Airplanes (both powered and gliders), rotorcraft (gyroplanes only, not helicopters), powered parachutes, weight-shift control aeroplanes (commonly known as trikes), and lighter-than-air craft (free balloons and airships) may all be certificated as LSA if they fall within the weight and other guidelines established by the local governing authority.
The US definition of an LSA is similar to some other countries' definition of "microlight" or "ultralight" aircraft. Other countries' microlight definitions are typically less restrictive, not limiting airspeed, the use of variable-pitch propellers, or the 1,320 pounds (600 kg) gross weight limitation.
By contrast, the US FAA has a separate definition of ultralight aircraft defined in Federal Aviation Regulations. Aircraft falling within the US ultralight specifications are extremely lightweight (less than 254 pounds if powered, or 155 pounds if unpowered), are intended for operation by a single occupant, have a fuel capacity of five US gallons (about 19 litres) or less, a maximum calibrated airspeed of not more than 55 knots (102 km/h; 63 mph), and a maximum stall speed of not more than 24 knots (44 km/h; 28 mph). Ultralight aircraft in the US do not require pilot licensing, medical certification, or aircraft registration.
Aircraft certified as light-sport aircraft exceed the limitations defined for ultralight aircraft and require that the pilot possess, at a minimum, a sport pilot certificate. Among these aircraft were found those that were specifically designed to meet the LSA requirements, as well as overweight ultralights (commonly known as "fat ultralights") that previously were operated in technical violation of 14 CFR 103.
In addition to aircraft specifically designed to meet the LSA requirements, certain certificated aircraft, such as the original Piper Cub, happen to fall within the definition of a light-sport aircraft and can be operated by individuals holding FAA sport pilot certificates. The aircraft can not be re-certificated as LSA, however: although sport pilots may operate conventionally certificated aircraft that fall within the definition of an LSA, the aircraft themselves continue to be certificated in their original categories.
Several designers and manufacturers of experimental aircraft kits have developed models that are compliant with the light-sport aircraft rules.
In June 2012 the FAA indicated that they would re-visit the LSA program after their own studies indicated that "the majority" of LSA manufacturers they had inspected failed to show that they were in compliance with the standards. The FAA announcement said that as a result the "original policy of reliance on manufacturers' Statements of Compliance" ... "should be reconsidered."[7] AOPA points out that this is a normal development of a maturing standard[8] and does not expect any significant changes in the rules, only more scrutiny by FAA to assure compliance.
The FAA announced on July 24, 2023, that it was considering expanding the Light Sport Aircraft category to incorporate the development of emerging technologies, in particular electrically-powered rotorcraft.[9]
The LSA category is expected to be drastically expanded with the introduction of MOSAIC (Modernization of Special Airworthiness Certification). Among the main proposed changes is the elimination of the current limitation on maximum weight, based on parameters related to stall speed, which will be 54 knots with the aircraft clean or with fixed or automatic high-lift devices (instead of the previous 45 knots). This will allow for larger aircraft (around 3,000 lbs maximum weight, approximately 1,350 kg), enabling increased safety margins, durability, and comfort for new aircraft certified under this new standard.[10] Currently, MOSAIC is in the process of public consultation, which will last about 90 days (until mid-October), with the final regulations scheduled for 2024.
Aircraft that met light-sport requirements when the rules were announced appear in an FAA list[11] Some additional models of S-LSA, E-LSA and E-AB aircraft that meet light-sport requirements are listed here. The FAA maintains a complete list of approved SLSA aircraft models.[12]

In June 2011, the European Aviation Safety Agency published CS-LSA "Certification Specifications for Light Sport Aeroplanes".[14] This introduced a new category of manufactured sport aeroplanes similar to the light-sport category found in the US and elsewhere.
A new certification category for 'Light Sport Aircraft' came into effect on 7 January 2006.[15] This category does not replace the previous categories, but created a new category with the following characteristics:[16]
Light-sport aircraft can be factory-manufactured aircraft or kits for amateur-building.
On 26 December 2022, Japan Civil Aviation Bureau amended the Circular of Aircraft Safety No.1-006 and clarified its own stance on LSA. The significant difference between Japan and other countries described above is that LSA in Japan is defined as a type of Experimental aircraft, i.e., non-certified aircraft, similar to amateur-built aircraft but rather than practical aircraft, i.e., certified aircraft. Permission for Test Flights etc. by Minister of Land, Infrastructure, Transport and Tourism is necessary to operate LSA in Japan as well as other non-certified aircraft. In order to operate the LSA in Japan, the aircraft, like other non-certified aircraft, requires permission for test flights, etc. from the Minister of Land, Infrastructure, Transport and Tourism. Because the LSA flight is nominally a test flight of an unknown experimental aircraft, the pilot may not have a license and the flight range is basically restricted to within 3 km of the takeoff/landing point avoiding residential areas. If the pilot of the LSA intends to fly outside of the above range or to land outside of the takeoff point, the pilot must have a Private Pilot license or a higher license and an effective aviation medical certificate. The required characteristics of LSA in Japan are modeled after those of S-LSAs in the United States. On the other hand, the E-LSA classification has not been introduced, so kit-built and plan-built LSAs are regarded as amateur-built aircraft. Imported LSA certified as CS-LSA is considered LSA on an exceptional basis, even if it does not meet the characteristics of LSA in Japan.[17]
