## Discrepancy

DURING B CHECK INSPECTION OF NR1 ENGINE, THE UPPER ANTI-ICE DUCT COUPLING WAS FOUND TO BE MISSING   FROM THE   UPPER ANTI-ICE DUCT ASSEMBLY. THE COUPLING WAS FOUND RESTING BETWEEN THE HIGH PRESSURE   COMPRESSOR   CASE AND THE RIGHT SIDE VSV ACTUATION LEVER. FURTHER INSPECTION ALSO FOUND SEVERAL WIRING HARNESSES,   ELECTRICAL CANNON PLUGS, AND BOTH FAN REVERSER OPENING ACTUATORS WITH EXCESSIVE HEAT DAMAGE. ENGINE ASSEMBLY, THE UPPER ANTI-ICE DUCT COUPLING, AND BOTH FAN REVERSER OPENING ACTUATORS WERE REPLACED.
