## Discrepancy

ON APPROACH, CREW DID NOT RECEIVE ANY LANDING GEAR INDICATION LIGHTS AFTER GEAR EXTENSION.  A MISSED APPROACH WAS EXECUTED.  CREW TESTED THE LIGHTS BUT HAD NO ILLUMINATION OF THE GEAR LIGHTS.  BULBS CHECKED OK ALONG WITH CIRCUIT BREAKERS.  MAINTENANCE FOUND THE SECTION 5, MASTER CAUTION CB TRIPPED.  RESET BREAKER.  OPERATIONAL CHECK GOOD. NO FURTHER REPORTS AS OF 7/2/2004.
