Simply not true, John. A DAS must be tied to a repair station. There
are many STC holders that are not repair stations.

The Authority to self aprove parts is in CFR 14 Part 21, "DAS"; for an STC
the DAS owns.

They still can
produce approved parts without a PMA. The reference is FAR 21.435

Who aproved the parts, if there is no PMA, or TSOA?
