Re: The other Boing and FAA fail

Yea, there's some conflicting infos on who gets to claim that wiring issue.

If you believe Seattle Times (I have no reason not to, at least with respect to their comprehensive articles on Boeing), I recalled reading this article from way back when there wasn't (much) COVID.... (https://www.seattletimes.com/business/boeing-aerospace/faa-faces-dilemma-over-737-max-wiring-flaw-that-boeing-missed/), FAA found this.

Apparently this incongruent routing has been in existence since the 737NG. However, when the 737NG was certified, that wire bundle routing path was legal. One more example of Boeing going, "hey, let's lean on the old ways of doing shit to save on re-engineering and re-training costs."

Reading more into the EASA (https://ad.easa.europa.eu/blob/EASA_PAD_20_184.pdf/PAD_20-184_1), they do mention Service Bulletin 737-27-1318, Revision 2... but I find also listed in the Federal Register (https://www.govinfo.gov/content/pkg/FR-2020-11-20/pdf/2020-25844.pdf).

Interestingly enough - they speak about hot wires and control wires, or likely high voltage and low voltage wiring, respectively shorting across another. Incidentally that is likely what contributed to the downing of TWA 800 way back when.
