Please read my words again.
They are currently stood down.
The allegations are not that they damaged an aircraft or refused to sign off a defect.
The allegations are that they raised a defect for further investigation. ie, they wrote in Tech Log - Cockpit door found to have gap between **** and **** that a small object can be inserted into to unlock door.
They are alleged to have deliberately been looking above and beyond what they were told to look for. Company claim that the daily check requires a general cabin inspection, not a detailed cabin inspection and the defect they found could not be picked up in a general cabin inspection.
They didn't fix it because they were not long off going home and didn't know what component would fix the problem that was essentially a design flaw.
