MD80 CUT IN FRONT OF A B747 ON THE TIPTOE VISUAL AT SFO.

Narrative

FINAL APCH PATH TRANSGRESSION. CLRED TIPTOE VISUAL APCH RWY 28L SFO. MY ROLE AS CAPT WITH FO FLYING. BAY ASKED THAT WE KEEP OUR SPD UP DUE TO TFC ABEAM US FOR RWY 28R; A B747 AT 180 KTS. OUR SPD 250 KTS. AT 14 DME OAK VOR; PROC CALLS FOR A 310 DEG HDG TO INTERCEPT THE RWY 28L LOC. AFTER ESTABLISHED 310 DEG HDG; I REACHED OVER TO TUNE THE LOC AND SET THE COURSE ON THE FO NAV HEAD. AS I LOOKED UP; I COULD SEE THAT THE FO HAD NOT LED THE TURN TO FINAL AND WOULD BE HARD PRESSED TO NOT FLY THROUGH THE LOC. I COMMANDED A TURN AND A 15 DEG BANK WAS ESTABLISHED. I EMPHATICALLY COMMANDED A HARD TURN WHICH WAS IMMEDIATELY COMMENCED. NEVERTHELESS; WE FLEW THROUGH BOTH THE RWYS 28L AND 28R FINALS IN FRONT OF THE B747 WHICH WE HAD BY THEN OVERTAKEN. THE APCH WAS COMPLETELY MISHANDLED IN SPITE OF THE GOOD WX AND LIGHT WIND. ATC MADE NO MENTION OF THE INCIDENT. THE ONLY SURE WAY I CAN PREVENT INCIDENTS LIKE THIS IS TO FLY ALL THE LEGS AT LEAST I KNOW WHAT TO EXPECT FROM MYSELF. TO BRIEF EVERY CONTINGENCY MIGHT BE COUNTER-PRODUCTIVE TO CRM GOALS.
