Not to pick nits but most DARs will include in a ship's operating limitations boilerplate that-- with exception of the builder (who receives a repairman's certificate limited to repairs, inspections and mods that specific aircraft only)-- annual condition inspections, repairs or modifications are to be performed by someone holding at least an A&P certificate (standard certificated aircraft require an A&P with Inspection Authorization for annuals and major repairs or mods). The FAA does allow pilot/owners to do some common maintenance items, like lubrication, brake servicing, or tire changes. In case someone else hasn't already pointed it out, the FAR's place responsibility for aircraft airworthiness on the owner, not the maintainer, so keep up with researching service bulletins and airworthiness directives-- your A&P will thank you come annual time.
