US Light Sport Aircraft
LSA rules for aircraft and Sport Pilot categorisation for pilots came into effect on 1 September 2004, affecting current and future aircraft with a gross weight of less than 598 kg (1,320 lb) only while flying in US territory. There are three subcategories.
Sport Pilot - Experimental: Existing Experimental category aircraft (including amateur-builts, ultralights and flex-wings) which owners may, should they wish, transfer to Sport Pilot category registration before 31 January 2008.
Sport Pilot - Standard: Existing aircraft with a certificate of airworthiness specifying MTOW below 1,230 lb, including some versions of Aeronca, Luscombe, Piper Cub and Taylorcraft. These must continue to be maintained to FAA certification standards, but can be flown by Sport Pilots.
Special LSA: Factory-built, ready-to-fly aircraft designed and constructed in accordance with the ASTM (American Society of Testing and Materials) consensus standards for light-sport aircraft. S-LSA aircraft do not receive FAA type certification; once the first example in the US has been granted a certificate of airworthiness and that form (FAA 8130-7) lodged with the Experimental Aircraft Association, the design is taken as ‘approved’ and further machines are automatically accepted.
Those S-LSAs approved by January 2007 are given with their official US name, which may differ in some cases from the listing in Jane's because of marketing under the name of an American agent.
