The Term Light Sport Aircraft (LSA) Is A Description Of An Aircraft, Not A Specific Type Of Aircraft Airworthiness Certification
Anyone that holds a sport pilot certificate, or anyone that is exercising sport pilot privileges, is limited to flying an aircraft defined as a light sport aircraft. If a pilot is not limited to sport pilot privileges, an LSA may be a perfect choice for an aircraft, but it’s not a required choice. LSA is a definition of an aircraft and is not necessarily related to the aircraft airworthiness certificate.
