Narrative

I WAS INFORMED BY MGMNT THAT ACFT R-HAND OVERWING SLIDE AND COMPARTMENT DOOR WERE MISSING ON ARR AT ZZZ IN MAY/XB/07. ACFT WAS IN ZZZ1 FOR B-CHK MAY/XA/07. I WAS ACCOMPLISHING WORK CARD; REARMING OF L AND R OVERWING SLIDES. AFTER ACCOMPLISHING REARMING PROCS OF L-HAND OVERWING SLIDE; I PROCEEDED TO THE R-HAND OVERWING SLIDE. I REPOSITIONED THE DISARM LEVER TO THE ARMED POS WHILE HOLDING DOWN THE SWITCHES; AND VERIFIED THE SWITCHES WERE IN THE DOWN POS AS PER WORK CARD. WHILE CONNECTING THE CANNON PLUG TO THE BATTERY PACK I HEARD THE SQUIBS FIRE. I THEN DEACTIVATED THE R OVERWING SLIDE SYS. I INITIATED MAINT WRITE-UPS FOR 2 EACH DOOR OPEN ACTUATORS; DOOR LATCH ACTUATOR AND SPOILER OVERRIDE ACTUATOR. AFTER WHICH I CHANGED THE 2 DOOR OPEN ACTUATORS AND THE SPOILER OVERRIDE ACTUATOR. I RECONNECTED THE CANNON PLUG TO THE SPOILER OVERRIDE ACTUATOR AND PERFORMED THE SQUIB TEST; WHICH FAILED. I FOUND THE SQUIB DISCHARGED ON THE NEW SPOILER ACTUATOR. I VERIFIED THE R-HAND OVERWING SLIDE SYS WAS DEACTIVATED. THEN I AOG'D THE PARTS REQUIRED: THE STATUS OF THE ACFT WAS GIVEN TO NEXT SHIFT. SUPPLEMENTAL INFO FROM ACN 741199: MAY/XA/07; DURING ROUTINE POST CHK CLOSE UP; A STEP WAS INCORRECTLY ACCOMPLISHED AND RW OFF WING DOOR SLIDE ACTUATOR DISCHARGED.
