## Discrepancy

REMOVED MAGNETO FOR INSPECTION.  IN THE PROCESS OF INSPECTING COUPLING PAWL PINS (WHICH REQUIRES REMOVAL OF COUPLING FROM MAGNETO) OBSERVED THAT COUPLING SPRING IS SHOWING ABNORMAL WEAR JUST AFT OF THE CENTER OF SPRING ATTACH POINT.  WEAR IS A RESULT OF CONTACT BETWEEN SPRING AND COUPLING DRIVE HOUSING POST.  NO ABNORMAL OILING OR CORROSION OBSERVED ON COUPLING ASSEMBLY.  PAWL PINS AND PAWLS IN GOOD CONDITION WOULD PASS INSPECTION.
