Are you still here? Maybe you can answer this question I posed to you back
on March 16, 2004:

"Your App. Note 1 references an AC that was superseded back in 1996, AC
20-62C, which is now AC 20-62D. The current version says in the definition
of "Acceptable Parts": "(2) Parts produced by an owner or operator for
maintaining or altering their own product and which are shown to conform to
FAA-approved data." So how can an owner's home-made dimmer circuit can be
installed without any approved data?"

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?
