What worries me is if we're going to see some kind of relevant similarity with the 777X which afaik is 'type rated as the same as the existing 777', despite having new mechanical processes to fail (wing fold) and entirely new undercarriage. Still, the 777X is still some way from hitting customers, so maybe Boeing will spend some time contemplating the way they gamed type rating with the MAX before hitting customers.
