Narrative:
It has been brought to my attention that the maintenance manager at ZZZ has been improperly signing off items. Aircraft xyz had the right master valve replaced (reference maintenance manual 32-42-19-4). This procedure calls for bleeding of the brakes (reference 32-42-00 page 301). Maintenance manager signed off this item as not applicable on job card #abc. I am concerned about this maintenance practice. Deviation from the maintenance manual can create a hazardous situation.
