What does it mean to "sign off" on a modification to anexperimental aircraft?

For the most part a true and valid point, but I will raise one minor quibble:
In the context of US aircraft and the regulations thereof, the term "airworthy" has a specific meaning; it means that the aircraft conforms to the data in its type certificate. Both amateur-built and racing experimental aircraft operate under Special Airworthiness Certificates issued for the purpose of operating non-type-certificated aircraft. Technically speaking, since they do not have type certificates, they cannot be "airworthy." The phrase most often substituted in the regulations and elsewhere is "of a condition for safe operation."
Thanks, Bob K.
Good minor quibble point, I believe that the definition of "Airworthy" is "..a condition for safe operation." and you are correct and this is the wording I use when signing off an annual or condition inspection but the pilot looks at as "is the aircraft airworthy or not?" and the pilot is the last link in the chain.
