The OEM's QA people were the messengers that ended up sueing WITHOUT SUCCESS for dismissal for doing their damned job. Nothing was ever done to replace these parts as far as I am aware.
A disgraceful episode where Boeing QA inspectors responsible for acquisition of those 737 parts were told that they were rejecting too many sub standard parts from Ducommon. When they asked how they could keep up with production targets they were told to use the sub standard parts by either re drilling holes or using hammers to make the parts fit. When they took this to the FAA and the US Dept of Justice they lost their jobs.
For those thinking that Boeing’s cavalier attitude to safety is a modern thing, these events were 20 years ago.
