Unless the problem is known to Engineering, ie an EQPR has been submitted then there will be no bulletin. So if no-one has ever bothered to report it then the problem doesn't (in their eyes) exist. They are pretty good at sorting this stuff out.
Who at LR NL has been informed (someone can PM me the names) ? I know both the Technical specialists there and in all honesty I have never come across this particular problem or been told it by either of them.
Hell if someone emails me the specific details with any supporting documentation I'll submit the bloody EQPR.
