Narrative:
I became aware that an off-wing escape inflation cable and the regulator lanyard should be replaced on a B767; if the off-wing escape system operated with the regulator safety pin installed. I was a part of a 2-PERSON team assigned to arm the off-wing escape system on the 767. The first portion of the work card was accomplished; downstairs; with no issues. When we started to do the upstairs portion of the work card; the right forward was accidentally dislodged by my partner. As a result; we heard the squibs discharge. I initiated a non-routine for the replacement of the right spoiler override actuator; the right slide inflation cylinder; and the right compartment door-opening actuator. I now realize that I should have created a non-routine stating that the off-wing escape system was inadvertently operated with the regular safety pin installed. Most of the work was accomplished by other mechanics; but I did accomplish the rig of the right off-wing compartment door-opening actuator. Therefore; I never saw the caution for replacing the cable and lanyard I do not know if the cables were written up or changed at this time. Check aircraft records to see if correct maintenance occurred. If not; replace off-wing slide cables as soon as possible.
Original NASA ASRS Text
Title: A MECHANIC IS INFORMED AN OFF-WING ESCAPE SLIDE INFLATION CABLE AND REGULATOR LANYARD SHOULD BE REPLACED ON A B767; AFTER THEY ACCIDENTALLY DISCHARGED THE RIGHT FORWARD OFF-WING SQUIBS WITH THE SAFETY PIN INSTALLED.
Narrative: I BECAME AWARE THAT AN OFF-WING ESCAPE INFLATION CABLE AND THE REGULATOR LANYARD SHOULD BE REPLACED ON A B767; IF THE OFF-WING ESCAPE SYS OPERATED WITH THE REGULATOR SAFETY PIN INSTALLED. I WAS A PART OF A 2-PERSON TEAM ASSIGNED TO ARM THE OFF-WING ESCAPE SYS ON THE 767. THE FIRST PORTION OF THE WORK CARD WAS ACCOMPLISHED; DOWNSTAIRS; WITH NO ISSUES. WHEN WE STARTED TO DO THE UPSTAIRS PORTION OF THE WORK CARD; THE R FORWARD WAS ACCIDENTALLY DISLODGED BY MY PARTNER. AS A RESULT; WE HEARD THE SQUIBS DISCHARGE. I INITIATED A NON-ROUTINE FOR THE REPLACEMENT OF THE R SPOILER OVERRIDE ACTUATOR; THE R SLIDE INFLATION CYLINDER; AND THE R COMPARTMENT DOOR-OPENING ACTUATOR. I NOW REALIZE THAT I SHOULD HAVE CREATED A NON-ROUTINE STATING THAT THE OFF-WING ESCAPE SYS WAS INADVERTENTLY OPERATED WITH THE REGULAR SAFETY PIN INSTALLED. MOST OF THE WORK WAS ACCOMPLISHED BY OTHER MECHS; BUT I DID ACCOMPLISH THE RIG OF THE R OFF-WING COMPARTMENT DOOR-OPENING ACTUATOR. THEREFORE; I NEVER SAW THE CAUTION FOR REPLACING THE CABLE AND LANYARD I DO NOT KNOW IF THE CABLES WERE WRITTEN UP OR CHANGED AT THIS TIME. CHK ACFT RECORDS TO SEE IF CORRECT MAINT OCCURRED. IF NOT; REPLACE OFF-WING SLIDE CABLES ASAP.
