Narrative:
The autothrottles on aircraft xyz were on MEL. Another mechanic worked the autothrottle problem and did an operational check and cleared the autothrottle MEL. He signed the aircraft logbook off, that he did an operational check because he was not CAT IIIA qualified on an MD80. I was with him and observed this check which is the same check as a functional check. I then recertified the aircraft to CAT IIIA status by clearing the MEL-34-00. I neglected to make a separate logbook sign-off, stating that an autothrottle functional check was completed, which I should have per maintenance manual procedures. I did not realize this until the aircraft had already left the station. I didn't catch this because the autothrottles were on a work release item (a computer history item issued by workload planning) and the item was signed off and the MEL cleared. The CAT IIIA status was also a work release item which I signed off, when I recertified the aircraft.
Original NASA ASRS Text
Title: AN MD80 WAS DISPATCHED IN NON COMPLIANCE WITH NO REQUIRED LOGBOOK SIGN OFF STATING THE ACFT WAS CERTIFIED IN CAT IIIA AND FUNCTIONAL CHK WAS COMPLETED.
Narrative: THE AUTOTHROTTLES ON ACFT XYZ WERE ON MEL. ANOTHER MECH WORKED THE AUTOTHROTTLE PROB AND DID AN OPERATIONAL CHK AND CLRED THE AUTOTHROTTLE MEL. HE SIGNED THE ACFT LOGBOOK OFF, THAT HE DID AN OPERATIONAL CHK BECAUSE HE WAS NOT CAT IIIA QUALIFIED ON AN MD80. I WAS WITH HIM AND OBSERVED THIS CHK WHICH IS THE SAME CHK AS A FUNCTIONAL CHK. I THEN RECERTIFIED THE ACFT TO CAT IIIA STATUS BY CLRING THE MEL-34-00. I NEGLECTED TO MAKE A SEPARATE LOGBOOK SIGN-OFF, STATING THAT AN AUTOTHROTTLE FUNCTIONAL CHK WAS COMPLETED, WHICH I SHOULD HAVE PER MAINT MANUAL PROCS. I DID NOT REALIZE THIS UNTIL THE ACFT HAD ALREADY LEFT THE STATION. I DIDN'T CATCH THIS BECAUSE THE AUTOTHROTTLES WERE ON A WORK RELEASE ITEM (A COMPUTER HISTORY ITEM ISSUED BY WORKLOAD PLANNING) AND THE ITEM WAS SIGNED OFF AND THE MEL CLRED. THE CAT IIIA STATUS WAS ALSO A WORK RELEASE ITEM WHICH I SIGNED OFF, WHEN I RECERTIFIED THE ACFT.
