I am an inspector for Z airlines and on jun/ww/96 I received a routine job card to inspect the installation of the borescope plugs on aircraft #4 engine not being familiar with these plug locations, I asked another inspector who is borescope qualified on this type engine to assist me. As I read through the job card he pointed them out to me. I inspected these position and found all plugs to be secure. This happened at the maintenance facility. My foreman told me that after the aircraft was in service for a couple of days, one of the combustion plugs was found missing. My last day of work was on jun/xx/96. The aircraft left oakland jun/yy/96. I was informed on jun/zz/96.
