A B737-800 LEAD TECHNICIAN RPTS DIFFICULTY FINDING A PROC FOR REPLACEMENT AND TEST OF THE R MASTER CAUTION ANNUNCIATOR LIGHT ASSEMBLY.

Narrative

I RECEIVED A TURNOVER FROM THE NIGHT SHIFT FROM ACFT X. THE CREW HAD SENT A RPT ON A MAINT ITEM CONCERNING THE FO'S SYS ANNUNCIATOR LIGHTS; COMMONLY KNOWN AS THE 'SIX PACK.' AT THE TIME OF THE TURNOVER I WAS TOLD BY THE MECH THAT HE HAD DETERMINED THAT THE ANNUNCIATOR LIGHT ASSEMBLY WOULD NEED TO BE REPLACED; BUT THERE ISN'T ANY REMOVAL AND REPLACEMENT PROCS IN THE MAINT MANUAL. HE FURTHER STATED THAT HE HAD CONTACTED TECHNICAL SVC AND WAS GIVEN THE GUIDANCE; 'JUST INSTALL IT.' I CALLED MY MGR AND ASKED THAT HE CONTACT WHOMEVER TO GET A PROC TO ACCOMPLISH THE REPLACEMENT AND ANY OPS CHK REQUIRED. SHORTLY HE WAS IN CONTACT WITH THE TECHNICAL PUBS WHO REFERRED HIM TO GPM 2-01 PARAGRAPH C2. I BELIEVED THAT THE GUIDANCE WAS STILL NOT PROPER FOR THE REPLACEMENT OF THIS ASSEMBLY AND REQUESTED FURTHER INSTRUCTIONS. WE WERE THEN DIRECTED TO USE THE PROC IN MAINT MANUAL 33-18-00-02; MASTER DIM AND TEST LIGHTS; MAINT PRACTICES. THE SECTION IS A GENERIC DESCRIPTION FOR REMOVING AND REPLACING OF VARIOUS LIGHTS; MODULES; AND ASSEMBLIES. THERE ISN'T ANY SPECIFIC REMOVAL AND REPLACEMENT FOR THE SYS ANNUNCIATOR LIGHT ASSEMBLY; NOR A TASK SPECIFIC INSTALLATION TEST OTHER THAN THE LIGHT TEST FOR THE COCKPIT. THE SYS ANNUNCIATOR LIGHTS HAVE 2 LOCATIONS IN THE FLT DECK; ONE FOR EACH PLT; AND THE ANNUNCIATIONS DISPLAYED ARE DIFFERENT FOR EACH PLT. THESE LIGHTS ANNUNCIATE CRITICAL DISPATCH ITEMS; AND THERE HAVE BEEN MANY GND INTERRUPTS BECAUSE OF A LIGHT COMING ON AFTER GATE DEP. IS THE GENERIC LIGHT TEST THE PROPER TEST AFTER REPLACEMENT OF THE LIGHT ASSEMBLY? SHOULD THERE BE A TASK SPECIFIC REMOVAL AND REPLACEMENT FOR THIS ASSEMBLY? ALSO; WHEN THE FIELD CONTACTS TECHNICAL SVC ON ISSUES SUCH AS THIS ITEM; THE GUIDANCE SHOULD BE SOMETHING OTHER THAN JUST INSTALL IT; OR CITING A SECTION OF THE GPM.
