## Discrepancy

TAIL ROTOR BLADE  WAS FOUND IN A DELAMINATED STATE DURING A PREFLIGHT INSPECTION.   THE ABRASION STRIP HAD DELAMINATED FROM THE LEADING EDGE OF THE BLADE.  PROBABLE CAUSE OF DELAMINATION IS IMPROPER CURE TIME FOR THE BONDING ADHESIVE, IMPROPER MIXING OF THE BONDING ADHESIVE, AND OR IMPROPER BEND RADIUS TO METAL LEADING EDGE CAUSING IT NOT TO SEAT PROPERLY AGAINST THE BLADES CONTOURED LEADING EDGE.
