## Discrepancy

PRELOAD PLATES ARE MARKED WITH PN 100641 BUT CONFIGURED AS PN 100641-1. LOGBOOK INDICATES PROP WAS REMOVED ON 5/17/05 FROM AIRCRAFT D2-EVN, S/N UE-370 RT POSITION DUE TO DEEP GOUGE OVER ACCEPTABLE LIMITS.  PROP WAS OVERHAULED ON 7/14/05 WITH 824.0 TSN.  PRELOADS MAY HAVE BEEN INSTALLED AT THIS TIME IAW S/B HC-SB-61-278.  I DO NOT KNOW IF THE BEARINGS WERE REMOVED TO MAKE P/N 100641-1 OR THE PART WAS INCORRECTLY MARKED AT HPI.
