What was found

(CAN) WHILE DOING A DAILY INSPECTION ON THE TAIL ROTOR BLADES IT WAS NOTICED THAT THE LEADING EDGE WAS DEBONDING ON THE TRAILING EDGE OF THE LEADING EDGE ABRASION STRIP. THE LOCATION IS ABOUT 8 INCHES FROM THE TIP OF THE BLADE AND THE TOTAL LENGTH OF THE DELAM IS 4.5 INCHES. THE BLADE WAS REPLACED IMMEDIATELY WITH A SERVICEABLE BLADE. THIS IS THE NEW STYLE TAIL ROTOR BLADE WITH THE FULL LENGTH ABRASION STRIP. THE OTHER BLADE WAS INSPECTED AND NO DEFECTS WERE FOUND.
