## Discrepancy

DURING WALK AROUND CHECK, MX FOUND A HOLE 0.5" WIDE ON THE OUTER SLEEVE OF THE LONG FIXED CORE EXHAUST NOZZLE (LFCEN) ON THE NR 2 ENGINE.  THE HOLE IS 6.0" FROM THE EXHAUST SLEEVE T/E AT THE 11:00 O' CLOCK POSITION.  (DISPOSITION WAS MADE TO REMOVE ANY BURRS USING STANDARD PRACTICES AND ELEMENTARY OPERATIONS; RE-INSPECT EVERY (1) FLIGHT CYCLE, AND REPLACE NOZZLE WITHIN 25 FLIGHT CYCLES.)
