## Discrepancy

DURING APPROACH TO KHH AFTER THE LANDING-GEAR EXTENSION, THERE WAS NO INDICATION OF THE L/G AT THE EXT POSITION ON THE CENTRAL INSTRUMENT PANEL. BUT THE INDICATIONS OF THE L/G EXT POSITION ON THE OVERHEAD PANEL WERE NORMAL. THE CREW MADE A GO-AROUND, RETRACTED AND EXTENDED THE L/G ONCE MORE. AFTER THAT, THEY MADE A LOW APPROACH AND LANDED NORMALLY.   IAW FIM 32-09-801, BITE PSEU. NO FAULT FOUND. THEN DO THE ¡§LT¡¨ TEST ON GROUND. FOUND THAT THE L/G IND, WINDOW HEAT SYS A L/H, HYD ELEC PUMP IND, ENG FIRE L/R IND, FUEL JET PUMP ¡¨LT¡¨ WERE OUT OF FUNCTION.   IAW WIM 33-18-11 PAGE 101, REPLACED MASTER TEST RELAY AND MASTER DIM MODULE.   IAW AMM 33-18-00, GROUND OPERATION TEST, AND THE FUNCTION BACK TO NORMAL.   IA
