A C172 INSTRUCTOR AND STUDENT; DEPARTING OAK; MISINTERPRETED THE HOLD IN POS INSTRUCTIONS AS BEING CLRED FOR TKOF CLRNC.

Narrative

ON AUG/SAT/02; I CONDUCTED A 1 HR INTRODUCTORY TRAINING FLT WITH A FIRST TIME STUDENT OUT OF OAKLAND ARPT. I RECEIVED CLRNC FROM GND TO TAXI TO RWY 33 AT INTXN L AND UNDER MY INSTRUCTION MY STUDENT TAXIED TO THE INTXN AND I PERFORMED THE ENG RUN-UP. I CONTACTED OAKLAND TWR AND WAS ASKED IF I WOULD ACCEPT AN INTXN DEP. WHEN I DECLINED I WAS INSTRUCTED TO BACK TAXI DOWN THE RWY AND HOLD IN POS. I READ BACK THE BACK TAXI INSTRUCTIONS BUT DO NOT RECALL WHETHER I READ BACK THE POS AND HOLD INSTRUCTIONS. WE PROCEEDED TO BACK TAXI WITH MYSELF AT THE CTLS; AND TURNED 180 DEGS AT THE DEP END OF THE RWY AND LINED UP WITH THE CTRLINE. I REVIEWED THE TKOF PROC WITH MY STUDENT; COMPLETED THE BEFORE TKOF CHKLIST; AND INSTRUCTED THE STUDENT TO COMMENCE THE TKOF. WHEN CLBING THROUGH APPROX 200 FT THE TWR ANNOUNCED THAT WE WERE IN RADAR CONTACT AND HAD TFC ABOVE US AND TO THE L. TWR THEN INFORMED ME THAT I HAD DEPARTED WITHOUT A TKOF CLRNC. I SAW THE OTHER ACFT; POSSIBLY A SMALL CESSNA; APPROX 500 FT ABOVE US AT MY 10 O'CLOCK POS ON A HEADING PERPENDICULAR TO OURS. I DETERMINED THAT NO EVASIVE ACTION WAS NECESSARY AND CONTINUED WITH THE CLB. THE TFC PASSED SAFELY ABOVE US AND WE WERE HANDED OFF TO DEP AND CONTINUED THE FLT. THE CAUSE OF THE INCIDENT WAS MY MISUNDERSTANDING OF THE POS AND HOLD CLRNC. I AM ACCUSTOMED TO BEING CLRED FOR TKOF AT THE SAME TIME I AM CLRED TO BACK TAXI FROM THAT PARTICULAR INTXN AND SIMPLY HEARD WHAT I EXPECTED TO HEAR RATHER THAN THE CTLR'S ACTUAL INSTRUCTIONS. I AM A LOW TIME CFI WITH ONLY 8 HRS OF DUAL INSTRUCTION GIVEN AND I FEEL THAT I ALLOWED MYSELF TO BECOME DISTRACTED BY EXPLAINING THE TKOF PROCS TO MY STUDENT BEFORE AND DURING THE TAXI BACK WHICH PROBABLY CONTRIBUTED TO MISSING THE POS AND HOLD INSTRUCTIONS. IN ORDER TO AVOID A SIMILAR MISTAKE IN THE FUTURE I BELIEVE I SHOULD AVOID UNNECESSARY COCKPIT CONVERSATION AT TIMES WHEN COM WITH ATC IS CRITICAL. READBACK OF ALL ELEMENTS OF TAXI; AND TKOF CLRNCS SHOULD ALSO HELP PREVENT ME FROM COMMITTING THE SAME ERROR AGAIN.
