I think this is over-simplifying the situation. Yes, change the wiring for new builds to meet the regulations but It could well be that retrofitting the existing 800 or so 737's as mentioned in the article could increase the risk over-all. But I would not trust Boeing to make that calculation and even the FAA's reputation has been dented (which is why I think they are being hard-arses about it) but it could be retrofitting is not the right choice. I would probably be happier if the FAA and the ESA decided independently whether to allow it.
