Check out AC 43-210A.

The logic of a minor alteration is good…but since an STC exists for this alteration, it is considered a Major alteration by definition. It’s a kind of catch 22. This would make for a great legal challenge. Did the FAA erroneously issue an STC? An STC can not be granted for a minor alteration.

But I like the statement (paraphrased) “…if you ask the FAA it’s out of your hands.”
