A B732 CREW WHILE ON APCH TO JFK EXCEEDED ASSIGNED AIRSPEED.

Narrative

WE WERE ON THE CAMRN 4 ARR. WE WERE LEVEL AT 18000 FT. WE WERE GIVEN A CLRNC TO DESCEND AND CROSS CAMRN INTERSECTION ALT 11000 FT AND 250 KTS; THEN WE WERE TURNED OVER TO NY APCH. I READ BACK THE CLRNC AND WE BOTH POINTED TO THE ALT WINDOW. I CHKED IN WITH APCH. WE LEVELED OFF AT 11000 SEVERAL MILES BEFORE CAMRN; 6 TO 10 MILES BEFORE. I WAS CHKING ARPT DIAGRAMS AND OUR RAMP PROCS BECAUSE WE WERE GIVEN A GATE WHICH WE GENERALLY ARENT ASSIGNED. APCH GAVE US A 030 DEG HEADING. SEVERAL MINS LATER APCH ASKED US OUR SPEED. I LOOKED UP AND READ THE AIRSPEED OF 300 KTS AND RESPONDED AS SUCH. AT THE SAME TIME I REALIZED THAT WE WERE 15 TO 20 MILES PAST CAMRN AND 50 KTS ABOVE OUR ASSIGNED SPEED. THE CTLR DID NOT SEEM ANGRY AND DID NOT INDICATE A PROB. HE ISSUED US A 320 DEG HEADING FOR THE SPEED REDUCTION. I ASKED THE FO IF HE REALIZED THAT WE WERE TO FLY 250 KTS AT CAMRN. HE STATED THAT HE THOUGHT WE WERE RELIEVED OF THE SPEED RESTRICTION BECAUSE WE WERE VECTORED BEFORE CAMRN. WE COMPLETED THE APCH AND LNDG UNEVENTFULLY. DURING TAXI TO THE GATE; FO HAD TO CONFIRM GATE ASSIGNMENT AND AVAILABILITY ON TWO DIFFERENT FREQUENCIES. HE GENERALLY DOES IT ALL ON NUMBER 2 RADIO. NUMBER ONE RADIO IS LEFT ON GND. MY EYES WERE ON THE TAXI RTE AND I HEARD THE FO WORKING ON THE GATE ASSIGNMENT. I NOTICED THE SIDE TONE WAS LOUD AND LOOKED AT RADIO ONE; WHICH HE SWITCHED TO GATE FREQUENCY FROM GND. I SWITCHED IT BACK TO GND AND CONTINUED TAXIING. I TOLD HIM WE HAD TO MONITOR GND. I AGAIN LOOKED AT NUMBER ONE RADIO AND HE HAD SWITCHED FROM AROUND GAIN. I SWITCHED IT BACK AND REPRIMANDED HIM. I THEN CONTACTED GND AND THEY TOLD US TO STOP. THEY HAD BEEN TRYING TO CONTACT US. THERE WERE NO CONFLICTS. I ATTRIBUTED THIS RADIO PROB TO HIS (FOS) NERVOUSNESS. MY SITUATIONAL AWARENESS WAS DIMINISHED DUE TO FATIGUE; I RELAXED MY SUPERVISION OF THE FO DUE TO MY INCORRECT ASSUMPTION THAT HE DIDNT NEED IT AS MUCH. I WAS CONSULTING CHARTS DURING A PHRASE A FLT THAT ALL OF MY ATTENTION SHOULD HAVE BEEN ON NAVIGATION AND COMMUNICATION. SUPPLEMENTAL INFO FROM ACN 530540: WE WERE FLYING THE CAMRN 4 ARR INTO NY. AT THE HOGGS INTERSECTION WE WERE GIVEN A CLRNC TO DESCEND FROM FL180 TO 11000 FT BY CAMRN AT 250 KTS. SINCE WE WERE DESCENDING THROUGH FL180; I CALLED FOR THE DSCNT CHKLIST. AFTER FINISHING THE CHKLIST I REALIZED THAT I NEEDED TO EXPEDITE MY DSCNT IN ORDER TO MAKE THE CROSSING RESTRICTION AT 11000. SINCE 11000 IS AN ALT WHERE I WOULD NORMALLY BE AT 300 KTS; I FORGOT THAT THE CTLR ALSO WANTED ME TO SLOW TO 250 KTS BY CAMRN. NY CTR CALLED US AND ASKED US OUR SPEED AND WE REPLIED 300. AT THE TIME WHEN WE WERE ASKED WE HAD JUST BEEN VECTORED OFF THE CAMRN FOUR ARR. WE IMMEDIATELY SLOWED TO 250 AS HE ASKED US. HE GAVE US A FEW VECTORS AND THEN VECTORED US FOR THE ILS TO 31L AT JFK.
