## Discrepancy

DURING 100 HR INSP DAMAGE LOCATED APPROX 1.25 INCHES FROM THE OTBD END OF THE BLADE TIP, ALONG THE AFT EDGE OF THE ABRASION STRIP ON THE LOWER SURFACE, AND MEASURES 1.00 INCH WIDE BY .50 INCHES LONG (FWD/AFT).  THE OVERALL SIZE OF THE DAMAGE IS ROUGHLY THE SIZE OF A QUARTER,  WITH APPROX (2) COMPOSITE PLIES MISSING.  TAP TESTING OF THE AREA HAS DETERMINED THAT AN APPROX .1875 INCH BAND OF DEBOND DAMAGE EXIST AROUND THE DAMAGE AREA, AND THAT THE ABRASION STRIP IS INTACT (NO EVIDENCE OF DEBONDING).  REPLACEMENT BLADE ON ORDER.
