ATCT local controller observed an A300 overtaking an SF34 on final for runway 31R and prior to taking action was told by the approach controller to break the A300 out of sequence. The local controller assessed the situation and turned the SF34 off his visual approach since the A300 had not yet checked in with him. When the A300 was contacted he was allowed to continue his approach and land.

Narrative:
Air carrier X an SF34 was on a visual approach to runway 31R at jfk. He was at 3000 ft following a jet ahead who was at 2000 ft. The separation between air carrier X and the aircraft ahead was sufficient. Behind air carrier X on an ILS runway 31R approach was air carrier Y H/A300. Air carrier Y never checked in on frequency, was at 2000 ft and seemed established on the localizer to runway 31R. As the air carrier X (SF34) descended to land runway 31R the separation with air carrier Y started to decrease. N90 approach control called to tell us to take air carrier Y out of sequence when he was 100 ft below and 1 mi in-trail and 30 KTS faster (ground speed) than air carrier X. Air carrier Y was still not on frequency. I turned air carrier X immediately to a 090 degree heading, climb and maintain 3000 ft and issued the traffic. I then called air carrier Y and he was on the frequency, so I issued the traffic and landing clearance. If air carrier Y had been 'taken out' of sequence I believe that there would have been enough time for the aircraft to turn anywhere (he could not climb, he was below the SF34) and not hit the other aircraft.

Title: ATCT LCL CTLR OBSERVED AN A300 OVERTAKING An SF34 ON FINAL FOR RWY 31R AND PRIOR TO TAKING ACTION WAS TOLD BY THE APCH CTLR TO BREAK THE A300 OUT OF SEQUENCE. THE LCL CTLR ASSESSED THE SIT AND TURNED THE SF34 OFF HIS VISUAL APCH SINCE THE A300 HAD NOT YET CHKED IN WITH HIM. WHEN THE A300 WAS CONTACTED HE WAS ALLOWED TO CONTINUE HIS APCH AND LAND.
Narrative: ACR X AN SF34 WAS ON A VISUAL APCH TO RWY 31R AT JFK. HE WAS AT 3000 FT FOLLOWING A JET AHEAD WHO WAS AT 2000 FT. THE SEPARATION BTWN ACR X AND THE ACFT AHEAD WAS SUFFICIENT. BEHIND ACR X ON AN ILS RWY 31R APCH WAS ACR Y H/A300. ACR Y NEVER CHKED IN ON FREQ, WAS AT 2000 FT AND SEEMED ESTABLISHED ON THE LOC TO RWY 31R. AS THE ACR X (SF34) DSNDED TO LAND RWY 31R THE SEPARATION WITH ACR Y STARTED TO DECREASE. N90 APCH CTL CALLED TO TELL US TO TAKE ACR Y OUT OF SEQUENCE WHEN HE WAS 100 FT BELOW AND 1 MI IN-TRAIL AND 30 KTS FASTER (GND SPD) THAN ACR X. ACR Y WAS STILL NOT ON FREQ. I TURNED ACR X IMMEDIATELY TO A 090 DEG HDG, CLB AND MAINTAIN 3000 FT AND ISSUED THE TFC. I THEN CALLED ACR Y AND HE WAS ON THE FREQ, SO I ISSUED THE TFC AND LNDG CLRNC. IF ACR Y HAD BEEN 'TAKEN OUT' OF SEQUENCE I BELIEVE THAT THERE WOULD HAVE BEEN ENOUGH TIME FOR THE ACFT TO TURN ANYWHERE (HE COULD NOT CLB, HE WAS BELOW THE SF34) AND NOT HIT THE OTHER ACFT.
