CORPORATE SMT DEPARTS COMPANY ARPT WITHOUT RELEASE.

Narrative

AT COMPANY STRIP; THE COPLT; WHO USUALLY HANDLES THE RADIOS AND CLRNCS; WAS OUTSIDE THE ACFT BOARDING OUR PAX. DUE TO THE LACK OF DIRECT HOT LINE AVAILABILITY TO ZAN; THE UNICOM OPERATOR CALLED CTR ON THE REGULAR PHONE BEFORE OUR USUAL TIME OF REQUESTING A CLRNC WHICH IS AS WE BEGIN TO TAXI. I TOOK THE CLRNC WHICH HAD A 'HOLD FOR DEP.' WHILE I WAS COPYING THE CLRNC I WAS INTERRUPTED ON ANOTHER RADIO WITH A COMPANY CALL PERTAINING TO QUESTION ABOUT A PAX. WHEN WE WERE READY TO TAXI I TOLD THE COPLT I HAD THE CLRNC; AND I MENTIONED THE COMPANY INQUIRY ABOUT THE PAX. I FORGOT THE 'HOLD FOR DEP.' IN FACT I HAD NOT WRITTEN IT DOWN WHEN I WROTE THE REST OF THE CLRNC. WE COMPLETED OUR BEFORE TKOF CHKLIST AND DEPARTED. WE CONTACTED CTR; WERE IN RADAR CONTACT; AND THE FLT PROCEEDED NORMALLY. WHEN WE RETURNED TO OUR BASE AT UBW THE UNICOM MAN TOLD US WE HAD DEPARTED BEFORE CLRED FROM CTR. A COMBINATION OF DEVIANCE FROM THE USUAL ROUTINE; RECEIVING THE CLRNC BEFORE MENTALLY PREPARED TO DO SO; AND THE INTERRUPTION WITH COMPANY COMS RESULTED IN MY NOT WRITING THE 'HOLD FOR DEP' PART OF THE CLRNC DOWN. IN THE FUTURE I WILL SHUT THE COMPANY RADIO AUDIO OFF WHILE COPYING CLRNCS. IN ADDITION THE UNICOM MAN HAS BEEN ASKED NOT TO REQUEST A CLRNC FROM CTR BEFORE WE HAVE REQUESTED IT THROUGH HIM. ALSO; THE DIRECT CTR HOT LINE HAS BEEN REPAIRED SINCE THE INCIDENT OCCURRED.
