What was found
ON SUNDAY 12 13 15, A TAIL ROTOR BLADE, PN 500P3100-105, SN C922, 491.6 TSR, WAS FOUND IN A DELAMINATED STATE, DURING A PREFLIGHT INSPECTION. THE LE HAD DELAMINATED FROM THE BLADE ABOUT 2" IN LENGTH. PROBABLE CAUSE OF THE DELAMINATION IS IMPROPER CURE TIME FOR THE BONDING ADHESIVE, IMPROPER MIXING OF THE BONDING ADHESIVE & OR IMPROPER BEND RADIUS TO METAL LE CAUSING IT TO NOT SEAL PROPERLY AGAINST THE BLADE`S CONTOURED LE. TO PREVENT A RE-OCCURRENCE OF THE TAIL ROTOR BLADE LE DELAMINATION.
