## Discrepancy

NR 1 ENGINE FAN WOULD NOT ROTATE FREELY ON POSTFLIGHT INSP.  BINDING STILL PRESENT AFTER SEVERAL HOURS OF COOL DOWN TIME.  OUTSIDE VENDOR CALLED IN TO DISASSEMBLE ENGINE ENOUGH TO DETERMINE CAUSE OF BINDING.  IT WAS FOUND THAT MANY OF THE FIRST STAGE TURBINE BLADE RETAINING CLIPS WERE MISSING ALLOWING BLADE SHIFT.  TURBINE SECTION IS BEING REBUILT.  AC WILL BE RETURNED TO SERVICE AFTER RECEIVING AND INSTALLING REBUILT TURBINE SECTION OF ENGINE ASSY.
