During log-in procedure [for a] Low Pressure Turbine Module; I encountered new parts in damaged boxes. Upon investigating the parts inside; I found one each; Fifth (5th) Stage Shroud Seal segment with bent/damaged sealing strip. I rejected this part; on Job Planning Card (JPC) and Holding Tag. Two days later the part was shown to me. The part had been cold-worked to straighten the bent portion of the sealing strip. No one seems to know who tried to repair this part; or what repair procedures were authorized to do it. The Engine Inspection paperwork repair calls out for sending the part to Pratt-Whitney for repair.
An Engine Shop Inspector reports a new 5th Stage shroud seal segment with a bent/damaged sealing strip for a PW-2000 Engine Low Pressure Turbine Module had been cold worked to straighten the bent portion without authorized repair procedures.
