Narrative:
I was the relieving controller at sector D21. Oceanic; non radar sector using atops control system. In the briefing from the working controller; he indicated that aircraft was in a climb from FL360 to FL370. My impression was that the new altitude had been coordination but a minor time revision was not. However; neither had been performed; so the altitude change was not passed to the next facility. The aircraft entered santa maria oceanic airspace at FL370 but had been coordinated at FL360. The santa maria sector controller called the new york sector controller to confirm the difference in altitude and discovered the discrepancy. 3 human factors idented that caused this error: 1) the working controller should have coordination the change of altitude before issuing a climb clearance as required. 2) the working controller should have been distinct about the coordination needed to be done. 3) the relieving controller should have checked all the coordination data when examining the time revision information.

Title: ZNY CTLR PERMITTED ACFT TO ENTER ADJACENT AIRSPACE AT OTHER THAN EXPECTED ALT; CAUSED BY BRIEFING AND COORD FAILURE.
Narrative: I WAS THE RELIEVING CTLR AT SECTOR D21. OCEANIC; NON RADAR SECTOR USING ATOPS CTL SYS. IN THE BRIEFING FROM THE WORKING CTLR; HE INDICATED THAT ACFT WAS IN A CLB FROM FL360 TO FL370. MY IMPRESSION WAS THAT THE NEW ALT HAD BEEN COORD BUT A MINOR TIME REVISION WAS NOT. HOWEVER; NEITHER HAD BEEN PERFORMED; SO THE ALT CHANGE WAS NOT PASSED TO THE NEXT FACILITY. THE ACFT ENTERED SANTA MARIA OCEANIC AIRSPACE AT FL370 BUT HAD BEEN COORDINATED AT FL360. THE SANTA MARIA SECTOR CTLR CALLED THE NEW YORK SECTOR CTLR TO CONFIRM THE DIFFERENCE IN ALT AND DISCOVERED THE DISCREPANCY. 3 HUMAN FACTORS IDENTED THAT CAUSED THIS ERROR: 1) THE WORKING CTLR SHOULD HAVE COORD THE CHANGE OF ALT BEFORE ISSUING A CLB CLRNC AS REQUIRED. 2) THE WORKING CTLR SHOULD HAVE BEEN DISTINCT ABOUT THE COORD NEEDED TO BE DONE. 3) THE RELIEVING CTLR SHOULD HAVE CHKED ALL THE COORD DATA WHEN EXAMINING THE TIME REVISION INFO.
