In the United States, the FAA has addressed concerns about who would maintain LSA after these aircraft were certificated. The solution was to issue a repairman (LSA) certificate, similar in function to the repairman certificate that is issued to the builder of an experimental amateur-built aircraft. This repairman (LSA) certificate complements certificates issued to Airframe and Powerplant (A&P) mechanics and appropriately rated repair stations. 

REPAIRMAN (LSA) RATINGS. The repairman (LSA) certificate has two ratings: “inspection” or “maintenance.” 

A person holding a repairman (LSA) certificate with an inspection rating is limited to performing the annual condition inspection on an ELSA certificated under § 21.191(i) that the repairman owns and that is identified on the repairman certificate by the aircraft registration and serial number. Non-ownership of the aircraft identified on the holder’s repairman certificate will suspend the privileges of the certificate.

A person holding a repairman (LSA) certificate with a maintenance rating may perform maintenance and required inspections on SLSA and perform annual condition inspections on ELSA. The repairman can also perform ADs and or Aircraft Manufacturer Safety Directives issued against FAA-approved products installed on SLSA. Repairman privileges do not extend to performing maintenance on aircraft issued a standard airworthiness certificate or any kind of special airworthiness certificates other than those issued under §§ 21.190 and 21.191(i), even if those aircraft meet the definition of LSA as identified in § 1.1 (e.g., Piper J-3 Cub or RV-4). Each airman is also limited to the appropriate class of aircraft on which he or she received training (e.g., weight-shift-control aircraft or powered parachutes).
