A B737-300 TECHNICIAN RPTS CONFUSION ON OVERNIGHT SVC CHK JOB CARDS. NUMBERED CHKS DIFFER WITH REQUIREMENTS FOR NON ROUTINE CARD ENTRY CALLING FOR ADDITIONAL CHKS. (EXAMPLE) #2 CHK CALLS FOR PYLON PANEL SECURITY CHKS.

Narrative

I WAS ADVISED OF A SIT BY MY MGR REGARDING SOME PYLON SCREWS ON ACFT. I COMPLETED A MAINT SVC CHK ON THIS ACFT ON AUG/XA/06. IN THINKING BACK TO THIS NIGHT I RECALL PERFORMING A VISUAL INSPECTION OF THE #1 AND #2 UPPER PYLON PANELS. VISUALLY THERE WERE NO DEFECTS. AS EXTRA INSURANCE I THEN APPLIED MY SCREW DRIVER TO THE HEADS OF THE SCREWS ON THE LEADING EDGE OF THE UPPER STRUT TO WING FAIRING. ON THE #1 SIDE I WAS ABLE TO GET A 1/8-1/4 TURN ON 2 SCREWS. ON #2 SIDE I WAS ABLE TO GET A 1/8-1/4 TURN ON 3 SCREWS. I THEN CONTINUED ON TO THE REST OF MY TASK. THE MAINT SVC CHK HAS INSTRUCTIONS (ENGS -- STEP #1 ITEM B) TO GENERATE A NRC (NON ROUTINE CARD) TO INSTALL OR TIGHTEN FASTENERS. I DID NOT BELIEVE AT THE TIME THAT I DID EITHER WITH THIS MINIMAL MOVEMENT. WHILE THE MAINT SVC CHK STATES THAT; THE SVC CHK PAPERWORK STATES (20; ITEM B) TO GENERATE A NRC FOR LOOSE; PULLED OR MISSING FASTENERS; THE MAINT SVC CHK PER MT 312-00-01 HAS YOU CHKING THE SAME PANELS (11; ITEM B) BUT DOES NOT HAVE THE REQUIREMENT FOR THE NRC. I FIND THE REQUIREMENT TO DO THESE TASKS ON SEPARATE CHKS WITH DIFFERENT PAPERWORK REQUIREMENTS CONFUSING.
