I am assuming that the manufacturer has to be informed and push the information out to operators.
Not a good assumption.
First the operator has to report the incident or finding to a Boeing. Not all incidents/findings are reported
- some are reported because the operator wants some advice
- some are reported because the regulator requires a report.
Manufacturer then
reports some to the regulator as they affect the airworthiness
collects sufficient reports and analysis to advise the operator and/or
update service bulletins and provide corrective actions.
For major recurring problems the manufacturer may provide briefings
with de-identified operator data to all its customers
Examples like the ones you have suggested would probably only be "pushed" back out to the operator in an industry wide safety briefing spread out over multiple years of data.
