Narrative:

Air carrier X cleared to intersection 55 east robbinville at 10000 ft. For some reason in my planning, I was figuring 50 east. When first officer brought it to my attention it was too late to make any adjustments to cross 55 east at 10000 ft. He asked if he should tell ATC. My response was negative, as I felt if it was a problem, ATC would have contacted us. Nothing was said by ATC. After thinking about the situation, I decided I should have had first officer communicate with ATC to make sure there was no conflict. Complacency on my part with TCASII and island operation being such that we use this TCASII a lot to do our own controling. Returning to a 'real' radar environment in heavy traffic area was a mistake too not coordination with ATC even when no TCASII targets were present. Supplemental information from acn 294736: we were given a crossing restriction for our descent which we did not make. Our restriction was to cross 55 mi east of rbv VOR at 10000 ft. We were at approximately 12500 ft over the fix. I stated my doubts of our being able to make the descent to the captain, but he felt he could make it. I believe a stronger than anticipated tailwind played a large role in this occurrence.

Title: ALTDEV. ACR X XING RESTRICTION NOT MET. NON ADHERENCE TO ATC CLRNC.

Narrative: ACR X CLRED TO INTXN 55 E ROBBINVILLE AT 10000 FT. FOR SOME REASON IN MY PLANNING, I WAS FIGURING 50 E. WHEN FO BROUGHT IT TO MY ATTN IT WAS TOO LATE TO MAKE ANY ADJUSTMENTS TO CROSS 55 E AT 10000 FT. HE ASKED IF HE SHOULD TELL ATC. MY RESPONSE WAS NEGATIVE, AS I FELT IF IT WAS A PROB, ATC WOULD HAVE CONTACTED US. NOTHING WAS SAID BY ATC. AFTER THINKING ABOUT THE SIT, I DECIDED I SHOULD HAVE HAD FO COMMUNICATE WITH ATC TO MAKE SURE THERE WAS NO CONFLICT. COMPLACENCY ON MY PART WITH TCASII AND ISLAND OP BEING SUCH THAT WE USE THIS TCASII A LOT TO DO OUR OWN CTLING. RETURNING TO A 'REAL' RADAR ENVIRONMENT IN HVY TFC AREA WAS A MISTAKE TOO NOT COORD WITH ATC EVEN WHEN NO TCASII TARGETS WERE PRESENT. SUPPLEMENTAL INFO FROM ACN 294736: WE WERE GIVEN A XING RESTRICTION FOR OUR DSCNT WHICH WE DID NOT MAKE. OUR RESTRICTION WAS TO CROSS 55 MI E OF RBV VOR AT 10000 FT. WE WERE AT APPROX 12500 FT OVER THE FIX. I STATED MY DOUBTS OF OUR BEING ABLE TO MAKE THE DSCNT TO THE CAPT, BUT HE FELT HE COULD MAKE IT. I BELIEVE A STRONGER THAN ANTICIPATED TAILWIND PLAYED A LARGE ROLE IN THIS OCCURRENCE.
