What Red Line.
This so called thread was confirmed by three engineers that were less than pleased with the current systems in place and not pub talk.
As for maintenance paperwork system one engineer (concerned not to be identified for obvious reprisals) suggested talking to maintenance control to confirm their procedures and inefficiencies in paperwork.
All in all this has resulted in two of the three engineers lodgeing CAIR reports as they are fed up with the system and feel safety is being compromised.
