Validity of Type Certificate
The type certificate holder keeps the type certificate valid by continuously following airworthiness directives, issuing service bulletins and as well as providing spares and technical support to keep the aircraft current with the prevailing rules, even after the production of the type has stopped. This is what is meant by supporting the type and in this manner many out-of-production aircraft continue useful lives. STCs are also bound by the same rules. When the holder decides to stop supporting the aircraft type, the type certificate is returned to the regulators and the remaining aircraft fleet permanently grounded. In this manner the whole Concorde fleet was finally grounded when Airbus SAS surrendered its type certificate.

“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
“It used to be said that you had to know what was happening in America because it gave us a glimpse of our future. Today, the rest of America, and after that Europe, had better heed what happens in California, for it already reveals the type of civilisation that is in store for all of us.”
—Alistair Cooke (b. 1908)
“God gave the righteous man a certificate entitling him to food and raiment, but the unrighteous man found a facsimile of the same in God’s coffers, and appropriated it, and obtained food and raiment like the former. It is one of the most extensive systems of counterfeiting that the world has seen.”
—Henry David Thoreau (1817–1862)
