UNAUTH LNDG TOUCH-AND-GO WHILE TRAINING IN PROGRESS. PRACTICE INST APCH.

Narrative

OUR FIRST APCH WAS THE VOR RWY 19R AT CONCORD. WE EXECUTED THE MISSED APCH AND PROCEEDED TO EXECUTE THE NDB RWY 19R AT CCR. WHEN HANDED OFF FROM TRAVIS APCH TO CONCORD WE ADVISED CONCORD TWR THAT WE WERE WITH HIM. TWR THEN ASKED 'HOW WILL THIS APCH TERMINATE' AND TO 'RPT THE NDB.' THE STUDENT SAID THAT WE WOULD LIKE TO DO A TOUCH- AND-GO AND MAKE A STRAIGHT-OUT DEP AND THAT WE WERE JUST COMING UPON THE NDB. WE CONTINUED THE APCH AND SAW THE PLANE THAT TWR HAD CLRED FOR TKOF. WE DID NOT FEEL THAT THERE WAS ANY TFC CONFLICT AND THAT TWR HAD GIVEN MORE THAN ENOUGH SEPARATION. WE MADE A TOUCH-AND-GO AND ON CLBOUT TWR HAD TOLD US THAT WE DID NOT RPT THE FINAL APCH FIX AND THAT WE WERE NOT CLRED FOR A TOUCH-AND-GO. CONTRIBUTING FACTORS: BECAUSE I WAS INVOLVED WITH SHOWING THE STUDENT (I HAD ONLY FLOWN WITH HIM ONCE BEFORE) HOW TO TRACK AND EXECUTE AN NDB APCH I WAS NOT FULLY PAYING ATTN TO THE COMS. I HAD ASKED THE STUDENT IF WE WERE CLRED TO LAND AND HE SAID 'YES.' I ASSUMED THAT BECAUSE THE STUDENT RPTED 'COMING UP ON THE NDB' THAT NO ADDITIONAL RPT AT THE FINAL APCH FIX WAS NEEDED. IT WAS AN EARLY MORNING FLT AND THERE WAS HARDLY ANY OTHER TFC. BECAUSE OF THIS; I WAS NOT FULLY PAYING ATTN TO THE COMS BECAUSE I ASSUMED THAT IT WOULD NOT BE A PROB FOR APCH/TWR TO ACCOMMODATE US. CORRECTION ACTIONS: I SHOULD NOT HAVE TAKEN A NEW STUDENT'S WORD ON A CLRNC GIVEN. I SHOULD HAVE CHKED WITH TWR IF I WAS NOT SURE. I SHOULD NOT HAVE BECOME SO CAUGHT UP IN THE TEACHING ASPECT THAT I FORGOT TO FLY THE ACFT AND CONFIRM ALL COMS. I SHOULD NOT HAVE ASSUMED THAT TWR UNDERSTOOD THAT WE WERE AT THE NDB WHEN WE SAID 'COMING UP ON.' FROM NOW ON; I WILL RPT OVER THE FINAL APCH FIX EVEN IF IT IS REDUNDANT.
