C600 FLT CREW MISS THE XING RESTR ON THE ILS RWY 6 APCH TO TEB.

Narrative

WHILE ON ILS APCH TO RWY 6 AT TEB; A MANDATORY STEPDOWN TO 1500 FT WAS MISSED BY BOTH THE PLT (ME) AND COPLT. APPARENTLY; THIS IS A CHANGE TO THE APCH IN LAST FEW MONTHS. PRIOR TO THIS; THE CTLR WOULD USUALLY CLR THE ACFT TO 'CROSS DANDY AT 1500 FT; CLRED FOR THE APCH.' BUT THIS TIME IT WAS JUST 'CLRED FOR THE APCH.' SO WHILE STARTING DOWN THE GS; THE CTLR SAID 'LOOKS LIKE YOU MISSED THE STEPDOWN; THAT IS TFC BEING VECTORED OVERHEAD.' THE TCAS INDICATED THE TFC WAS 1300 FT ABOVE. HE THEN SAID IT WAS PART OF THE PUBLISHED APCH AND PASSED US TO TWR. LOOKING BACK ON THIS; IT WAS A FAILURE OF MINE TO NOT REVIEW THE APCH. MOST OF THE PLTS I FLY WITH ARE PRETTY GOOD ON BRIEFING; BUT THIS PLT SOMETIMES GETS LAZY AND GETS AN ATTITUDE. I SHOULD HAVE REVIEWED THE APCH MYSELF; AS I USUALLY DO AND THIS WOULD HAVE PREVENTED THE DEV. ALSO I DID THINK IT WAS ODD THAT WE DID NOT GET THE INSTRUCTION TO DSND FROM THE CTLR; AND I SHOULD HAVE QUERIED IT. FOLLOWING STANDARD BRIEFING PROCS WOULD HAVE PREVENTED THIS.
