Narrative:
First officer flying leg from pvd-bwi. Given clearance to cross troyz intersection on V378 at 12000 ft. After finding the location for troyz (non FMS equipped) we were late in getting down. First officer deployed speed brake, took autoplt out of pms mode to cws mode and was making rapid descent. I notified ZNY that we were unable to meet the restr. Center turned us to the right. My attention was distraction while getting approach speeds and when I looked up we were descending through 12000 ft. I told the first officer '12000 ft, 12000 ft.' and before he could arrest the descent, we reached 11600 ft. Primary factors were a clearance that required an immediate descent and the first officer taking the autoplt out of a mode that would have leveled the aircraft at 12000 ft.

Title: FLC OF ACR FAILS TO MAKE XING RESTR DUE TO INABILITY TO QUICKLY LOCATE THE INTXN. RECEIVED VECTOR UPON INFORMING ATC AND WHILE COMPUTING APCH SPDS FLC DSNDED BELOW ASSIGNED ALT.
Narrative: FO FLYING LEG FROM PVD-BWI. GIVEN CLRNC TO CROSS TROYZ INTXN ON V378 AT 12000 FT. AFTER FINDING THE LOCATION FOR TROYZ (NON FMS EQUIPPED) WE WERE LATE IN GETTING DOWN. FO DEPLOYED SPD BRAKE, TOOK AUTOPLT OUT OF PMS MODE TO CWS MODE AND WAS MAKING RAPID DSCNT. I NOTIFIED ZNY THAT WE WERE UNABLE TO MEET THE RESTR. CTR TURNED US TO THE R. MY ATTN WAS DISTR WHILE GETTING APCH SPDS AND WHEN I LOOKED UP WE WERE DSNDING THROUGH 12000 FT. I TOLD THE FO '12000 FT, 12000 FT.' AND BEFORE HE COULD ARREST THE DSCNT, WE REACHED 11600 FT. PRIMARY FACTORS WERE A CLRNC THAT REQUIRED AN IMMEDIATE DSCNT AND THE FO TAKING THE AUTOPLT OUT OF A MODE THAT WOULD HAVE LEVELED THE ACFT AT 12000 FT.
