A Non-Routine [write-up] was made for a 7th Stage blade that was damaged; bent on the knife edge. The Engineer was shown the defect and told us they would make a determination on the status of the blade the next day. Per the Engine Inspection paperwork [reference PW Manual] 72-53-42; the blade could only be repaired by the Outside Vendor (OSV) PER 72-53-42. When Swingshift came in; they discussed the situation and an Inspector did a blend repair per the General Notes (GN) 1-0-1-85. Nothing in the Engine Inspection paperwork gives us authority to repair the 7th Stage blade. The blade was blended and if you look at the blade; it still is bent slightly. I thought we are supposed to follow procedure on the Engine Inspection paperwork.
An Air Carrier Engine Shop Mechanic questions an in-house blend repair on a PW-2000 Engine 7th Stage Compressor blade that was found damaged; bent on the knife edge of the blade. Per their Air Carrier Engine Inspection paperwork; the blade could only be repaired by an Outside Vendor (OSV).
