Let's find out, first, where your confusion lies.

Any part installed on a certificated airplane has to be manufactured
according to FAA "approved data." Otherwise the airplane ceases to have a
valid airworthiness certificate.

Approved data can come from the manufacturer's drawings, an STC, a PMA, a
TSO, or, repeat, or, the Adminstrator can approve the data by way of a
337.

Do you agree with these two statements?
