Colin and those interested in building a KR that can be flown by a Sport Pilot, I sent an inquiry to the EAA. The following is my question and the response from Joe Norris:
To: info services Subject: Experimental LSA If I build a one-off original design aircraft that meets the requirements for an Experimental LSA what proof must I provide that it meets the requirements? Dick Hartwig EAA #84582 Waunakee, WI rhartwi...@juno.com Hello Dick, You simply must document, through flight test records, that the aircraft meets the light-sport aircraft (LSA) definition. The FAA is not going to do any special testing or inspection to document whether an amateur-built aircraft meets the LSA definition or not. It will be up to the builder/pilot to document this. Remember that it is the pilot's responsibility to assure that he/she is flying an aircraft that meets the definition, so if the aircraft you design and build appears to be close to the limits, it might be wise to have a private pilot (or higher) do the initial flight testing, at least to the point that the basic performance numbers are verified and recorded, so as to assure that the sport pilot is not operating an aircraft that does not fit the LSA definition. Hope this helps! Let me know if you have further questions. Joe Norris EAA Aviation Services EAA Aviation Center, Oshkosh, WI 888-322-4636, extension 6806 jnor...@eaa.org
