LTSS. APCH CTLR HAD 2 ACFT AT THE SAME ALT WITHIN 1 MI OF EACH OTHER NON VISUAL.

Narrative

WHILE DSNDING TO 7000 FT WE WERE HANDED OFF TO A NEW YORK CTLR. THE PNF CALLED NEW YORK SEVERAL (2-3) TIMES WITH NO ACKNOWLEDGEMENT. FINALLY AFTER ABOUT 4 TIMES NEW YORK CTLR (WHO WAS QUITE BUSY) TOLD US TO DSND AND MAINTAIN 4000 FT. THE PNF RADIOED ATC AND WE COMPLIED. WE WERE THEN GIVEN A 040 DEG HDG AND THE PNF RESPONDED OVER THE RADIO SEVERAL TIMES WITH NO ATC ACKNOWLEDGEMENT. WHEN WE WERE WITHIN APPROX 15 MI OF MMU; PNF RADIOED NEW YORK ATC (3-4 TIMES) IF WE COULD HAVE A LOWER ALT. FINALLY NEW YORK REPLIED TO US; 'IMMEDIATELY EXPEDITE TO AND MAINTAIN 2000 FT; TFC 1 O'CLOCK LESS THAN A MI AT 4000 FT.' WHILE TAKING IMMEDIATE ACTION; PNF ACKNOWLEDGED ATC. BEFORE REACHING 2000 FT; NEW YORK ATC TOLD US TO ADVISE MMU IN SIGHT. WE HAVE MMU IN SIGHT AFTER XMITTING 2-3 TIMES. ATC ACKNOWLEDGED US; HANDED US OFF TO TWR AND WE LANDED WITHOUT INCIDENT. IN MY OPINION THE EVENT WAS CAUSED BY A HVY WORKLOAD ON ATC. WHEN A CTLR DOES NOT ACKNOWLEDGE A RADIO CALL AFTER 2 OR SO TIMES; HOW DO WE KNOW THAT OUR RADIOS ARE WORKING. FOR YOUR INFO WE NEVER SAW ANY TFC AND OUR RADIOS WERE WORKING FINE ALL DAY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE CAPT SAID THAT THE APCH CTLR SEEMED DISTR THROUGHOUT THEIR CONTACT WITH HIM. AFTER LNDG THE APCH CTLR SEEMED DISTRACTED THROUGHOUT THEIR CONTACT WITH HIM. AFTER LNDG THE FLC DEPARTED AGAIN; BUT THEY DID NOT TALK TO THE SAME CTLR. THIS FLC OPERATES IN THIS AREA WITH THEIR BEECH KING AIR C90 OFTEN AND THIS IS THE FIRST ENCOUNTER OF THIS TYPE THAT THEY HAVE HAD.
