Narrative:
E190 on descent to jfk in vicinity of sie VORTAC. The aircraft was under the control of sie sector (59). Radar data briefly disappeared (approximately 5 miles) on the host display but was available in edarc (backup radar). The adjacent sector cyn (58) tried to view the same information; but no data was available in host from sie to hoggs intersection (on the camrn arrival; 38 NM). Radar targets and histories were available in edarc. Another aircraft was visible the entire time; overlapping the E190 on adjacent J121.
