Narrative:
First officer was in consolidation (less than 50 hours in type) and flying approach, ILS runway 25L at vhhh. When cleared for approach and given final vector, localizer failed to capture and first officer flew aircraft back to and captured localizer. Aircraft was high on GS and autoplt was disengaged and first officer corrected back to GS and course. First officer attempted to reengage autoplt by himself not in accordance with procedures and began to drift right off course due to strong winds, towards runway 25R. Distance of runway still approximately 7-8 mi. While attempting to correct back to localizer and just prior to first officer and captain initiating 'go around,' local ATC requested go around. Map indicated approximately 5 mi from and 2000 ft left of runway 25R. Subsequent approach and landing made without incident. Subsequent liaison with local ATC indicated no conflict with other traffic (closest 6 mi in trail, runway 25R) and no altitude deviation except +700 ft initially while attempting to capture GS on runway 25L. Local officials indicated possible localizer signal interference due to aircraft (B747) in proximity to transmitter while approach was initiated. First officer failed to use proper CRM after reestablishing localizer/GS and should have continued to simply 'hand-fly' aircraft.

Title: AN MD11 FLT HAS TO GO AROUND AFTER A DESTABILIZED APCH IS IMPROPERLY CTLED DURING AN AUTOPLT APCH TO RWY 25L AT VHHH, FO.
Narrative: FO WAS IN CONSOLIDATION (LESS THAN 50 HRS IN TYPE) AND FLYING APCH, ILS RWY 25L AT VHHH. WHEN CLRED FOR APCH AND GIVEN FINAL VECTOR, LOC FAILED TO CAPTURE AND FO FLEW ACFT BACK TO AND CAPTURED LOC. ACFT WAS HIGH ON GS AND AUTOPLT WAS DISENGAGED AND FO CORRECTED BACK TO GS AND COURSE. FO ATTEMPTED TO REENGAGE AUTOPLT BY HIMSELF NOT IN ACCORDANCE WITH PROCS AND BEGAN TO DRIFT R OFF COURSE DUE TO STRONG WINDS, TOWARDS RWY 25R. DISTANCE OF RWY STILL APPROX 7-8 MI. WHILE ATTEMPTING TO CORRECT BACK TO LOC AND JUST PRIOR TO FO AND CAPT INITIATING 'GAR,' LCL ATC REQUESTED GAR. MAP INDICATED APPROX 5 MI FROM AND 2000 FT LEFT OF RWY 25R. SUBSEQUENT APCH AND LNDG MADE WITHOUT INCIDENT. SUBSEQUENT LIAISON WITH LCL ATC INDICATED NO CONFLICT WITH OTHER TFC (CLOSEST 6 MI IN TRAIL, RWY 25R) AND NO ALTDEV EXCEPT +700 FT INITIALLY WHILE ATTEMPTING TO CAPTURE GS ON RWY 25L. LCL OFFICIALS INDICATED POSSIBLE LOC SIGNAL INTERFERENCE DUE TO ACFT (B747) IN PROX TO XMITTER WHILE APCH WAS INITIATED. FO FAILED TO USE PROPER CRM AFTER REESTABLISHING LOC/GS AND SHOULD HAVE CONTINUED TO SIMPLY 'HAND-FLY' ACFT.
