## Discrepancy

THIS PART WAS INSPECTED EARLY AT CONVENIENCE OF OPERATOR, TO MAINTAIN ACFT AVAILABILITY.  DURING C/W ALLIED SIGNAL AEROSPACE (FORMERLY TEXTRON LYCOMING) SB LT-101-72-50-0153 AND BELL ASB 222-93-63, USING DIAL INDICATOR INSPECTION METHOD TO DETECT BLADE SHIFT, FOUND ONE BLADE SHIFTED .014 INCH (MAX IS .010 INCH FOR ANY ONE BLADE).  THE PT ROTOR HAD A TOTAL OF 46.9 HRS/192 CYCLES SINCE INSTALLATION.  PER ALLIED SIGNAL, BLADE SHIFT IS CAUSED BY BLADE ATTACH RIVET WORKING LOOSE.  SUBMITTER STATED MANUFACTURER NEEDS TO COME UP WITH A PERMANENT FIX TO THE PROBLEM.  CYCLES, 192.
