## Discrepancy

DURING T/O AS THE NLG LEAVES THE GRD, A NOSE LIKE SHIMMY OR A TIRE IMBALANCE IS HEARD FOR APPROX. 3 SEC. THEN DURING RETRACTION THE NLG LIGHTS DIMLY FLICKER (BOTH RED & GREEN) UNTIL THE GEAR IS RETRACTED FULLY. MLG LIGHT ARE NORMAL. ALSO AT APPROX 20 MIN INTO THE FLIGHT DURING CLIMB WE NOTICED THE NLG LIGHTS FLICKER LIKE BEFORE.   REMOVED & REPLACED NOSE WHEEL DOWN LOCK SWITCH WITH NEW SWITCH OPS CHECKS GOOD PER 800XP MM 32-60-00 & WD 32-60-10-04.
