## Discrepancy

ON GEAR EXTENSION, THE NOSE GEAR DOWN AND LOCKED GREEN LIGHT DID NOT ILLUMINATE.  RECYCLED GEAR AND CHECKED LIGHTS AND C/B'S.  THE PROBLEM STILL EXISTS.  ACCOMPLISHED PROCEDURES AND CONFIRMED NOSE WHEEL RED STRIPES WERE ALIGNED AND LANDED.  DID NOTICE ACRID SMELL WITH GEAR EXTENSION.  REPLACED LANDING GEAR ANNUNCIATOR PANEL AND LANDING GEAR ACCESSORY UNIT PER MM 32-09-11, OPS CK OK.
