From the very first sentence that the guy wrote:

"I had this Audio Panel assembled by a professional. He charged $100.00
but said it ended up taking 40 hours.The work inside is first class."

Reading that sentence, can you POSSIBLY construe "owner built part" from
the process? He PAID somebody to do the work that the owner was supposed
to do himself. We are VERY CLEAR that the owner of the aircraft must do
the assembly or the part cannot be legally installed on a certificated
airplane.

Owner-produced doesn't mean "owner assembled" or "owner manufactured." My
understanding is that the FAR that allows this doesn't specify the owner has
to do the construction and/or assembly.
