## Discrepancy

DURING THE APPROACH INTO DTS CREW ATTEMPTED NORMAL GEAR EXTENSION, THE LEFT MAIN LANDING GEAR INDICATION DID NOT ILLUMINATE. THE CREW PERFORMED THE EMERGENCY EXTENSION PROCEDURE PER THE AFM. LANDING WAS UNEVENTFUL. DURING TROUBLE SHOOTING MAINTENANCE DISCOVERED AND REPLACED THE BULBS FOR THE LEFT MAIN GEAR DOWN AND LOCKED INDICATOR. GEAR SWINGS AND OPS CHECKS GOOD. AIRCRAFT RETURNED TO SERVICE.
