If NTSB concludes MAX plug doors were improperly fitted, who determines how far back any negligence extends?
I read yesterday after UA found the loose bolts that UA's oldest a/c were coming up on the c check that occurs every 2-3 years. During that check, those bolts would have been inspected. Assuming that the door plug is also inspected during the c check on the 739s, all of those aircraft are old enough they should already have had their door plug bolts inspected at least once.
