## Discrepancy

WHEN MLG EXTENDED ON ARRIVAL, GEAR CAME OUT OF WW & STOPPED.  CREW EXTENDED MLG WITH THE EMERGENCY EXTENTION SYSTEM. CREW FOUND IT VERY HARD TO MOVE HANDLE FOR 1ST FEW STROKES. WERE ABLE TO KEEP GOING UNTIL 3 GREEN LIGHTS.  LANDED A/C NORMALLY.  A/C PUT ON JACKS & 60 AMP C/B UNDER FLOOR FOUND BLOWN.  C/B RESET & GEAR SELECTED UP.  GEAR WENT UP NORMALLY.  GEAR SELECTED DOWN & GEAR MOVED SAME AMOUNT & STOPPED.  MLG MOTOR STILL TRYING TO MOVE GEAR, BUT FRICTION CLUTCH IN GEARBOX SLIPPING.  NLG CHAIN REMOVED IN ABLE TO SPLIT UP SYS FOR TROUBLESHOOTING. MLG FUNCTIONED NORMALLY.  NLG SYSTEM TALKEN APART & A BEARING IN 1 OF CHAIN SPROCKETS FOUND FAILED.  A NEW SPROCKET & BEARING INSTALLED & MLG FUNCTIONED NORMALLY.
