Narrative:

Aircraft was in VMC and being vectored for an ILS approach to runway 25L at lax by socal approach. The captain was flying the aircraft and the autoplt was engaged. Aircraft was descending through 4000 ft MSL and was cleared to 2000 ft while on an intercept heading to track the localizer inbound. Intercept vector positioned the aircraft close to the OM (limma). The first officer advised the captain that he was being brought in high for the approach as the GS had not been intercepted yet (full scale deflection). The air traffic controller assigned the crew to level and intercept at 3000 ft. First officer (PNF) reset the altitude window to 3000 ft on mode control panel. Aircraft leveled off at 3000 ft. The captain asked the first officer to verify the altitude (3000 ft). First officer verified 3000 ft assigned altitude with the controller. The controller came back and changed altitude to 2000 ft. Mode control panel was reset to 2000 ft and aircraft continued to descend and track the localizer but still had not yet intercepted the GS. Captain disengaged the autoplt and began to hand fly the approach. Current conditions at lax were reported as 900 ft overcast with no reported tops and a visibility of 2 mi. The captain continued to fly the approach in VMC without GS interception inside the OM. The first officer advised the captain to 'go around, the approach was not stable.' the captain continued to fly approach as the aircraft entered IMC. The first officer again advised the captain that the approach was not stable. The aircraft broke out into VMC and was established into a high sink rate. The aircraft's aural warning sounded 'sink rate, sink rate,' the captain finally executed a missed approach as he noticed that attempting to land could be dangerous. The aircraft was vectored around for another ILS approach for runway 25L and landed safely.

Title: CAPT OF AN MLG WAS BROUGHT IN HIGH DURING INTERCEPTION FOR AN ILS APCH RESULTING IN A MISSED APCH.

Narrative: ACFT WAS IN VMC AND BEING VECTORED FOR AN ILS APCH TO RWY 25L AT LAX BY SOCAL APCH. THE CAPT WAS FLYING THE ACFT AND THE AUTOPLT WAS ENGAGED. ACFT WAS DSNDING THROUGH 4000 FT MSL AND WAS CLRED TO 2000 FT WHILE ON AN INTERCEPT HDG TO TRACK THE LOC INBOUND. INTERCEPT VECTOR POSITIONED THE ACFT CLOSE TO THE OM (LIMMA). THE FO ADVISED THE CAPT THAT HE WAS BEING BROUGHT IN HIGH FOR THE APCH AS THE GS HAD NOT BEEN INTERCEPTED YET (FULL SCALE DEFLECTION). THE AIR TFC CTLR ASSIGNED THE CREW TO LEVEL AND INTERCEPT AT 3000 FT. FO (PNF) RESET THE ALT WINDOW TO 3000 FT ON MODE CTL PANEL. ACFT LEVELED OFF AT 3000 FT. THE CAPT ASKED THE FO TO VERIFY THE ALT (3000 FT). FO VERIFIED 3000 FT ASSIGNED ALT WITH THE CTLR. THE CTLR CAME BACK AND CHANGED ALT TO 2000 FT. MODE CTL PANEL WAS RESET TO 2000 FT AND ACFT CONTINUED TO DSND AND TRACK THE LOC BUT STILL HAD NOT YET INTERCEPTED THE GS. CAPT DISENGAGED THE AUTOPLT AND BEGAN TO HAND FLY THE APCH. CURRENT CONDITIONS AT LAX WERE RPTED AS 900 FT OVCST WITH NO RPTED TOPS AND A VISIBILITY OF 2 MI. THE CAPT CONTINUED TO FLY THE APCH IN VMC WITHOUT GS INTERCEPTION INSIDE THE OM. THE FO ADVISED THE CAPT TO 'GAR, THE APCH WAS NOT STABLE.' THE CAPT CONTINUED TO FLY APCH AS THE ACFT ENTERED IMC. THE FO AGAIN ADVISED THE CAPT THAT THE APCH WAS NOT STABLE. THE ACFT BROKE OUT INTO VMC AND WAS ESTABLISHED INTO A HIGH SINK RATE. THE ACFT'S AURAL WARNING SOUNDED 'SINK RATE, SINK RATE,' THE CAPT FINALLY EXECUTED A MISSED APCH AS HE NOTICED THAT ATTEMPTING TO LAND COULD BE DANGEROUS. THE ACFT WAS VECTORED AROUND FOR ANOTHER ILS APCH FOR RWY 25L AND LANDED SAFELY.
