Experimental light-sport aircraft
Experimental light-sport aircraft (E-LSA) may be flown by sport pilots. E-LSA kits that do not conform to amateur-built certification requirements and will be certificated in the E-LSA category must be based on an aircraft that has received a special LSA (S-LSA) airworthiness certificate. E-LSA must be operated in accordance with the operating limitations issued to the aircraft at the time it receives its airworthiness certification. It must be maintained in accordance with regulations as they apply to E-LSA. Its annual condition inspection may be conducted by an LSA repairman with an inspection rating, an LSA repairman with a maintenance rating, an airframe and powerplant (A&P) mechanic, or a certified repair station.
Experimental amateur-built aircraft
Experimental amateur-built aircraft that meet the definition of an LSA may be flown by sport pilots. The aircraft is certificated as experimental amateur-built and must be operated in accordance with the operating limitations issued to the aircraft at the time it receives its airworthiness certification. It must be maintained and inspected in accordance with regulations as they pertain to amateur-built aircraft. Its annual condition inspection may be performed by the original primary builder if he/she holds the repairman certificate for the aircraft, an A&P mechanic, or a certified repair station.
