Maintenance refuses to do anything about it!!!!!!!!!!
Highly unlikely.
This is an MEL conflict and has nothing to do with maintenance.
The MEL is in conflict with the companies operating procedures.
It is up to the operations department to resolve the issue and ammend the MEL.
Operations owns the MEL not maintenance.
If crews fly in breach of the companies operating procedures that is nothing to do with maintenance.
It appears to me that some of the crews are trying to shift the responsibilty for not flying the aircraft by getting the engineers to ground the aircraft for them.
Balls lack off!!!!!!!!!!!!!!!
