Narrative:
Holding for jfk arrs at CCC. First aircraft (A330) was assigned to cross CCC at 14000 ft upon hold entry. Second aircraft (B763) was assigned to cross CCC at 15000 ft upon hold entry. First aircraft did not comply with the 14000 ft restr and was still descending out of approximately 14600 ft on the outbound leg of the holding pattern resulting in the loss of minimum separation with the second aircraft who was level at 15000 ft on the inbound leg of the holding pattern.
