Narrative:

Schedule maintenance task to check 'engine F/B discharge cartridge continuity check.' while inspecting safeties of cannon plug's connector, I'd noticed that lanyards were missing. It was very late in the schedule to get aircraft out and lack of manpwr to drill out cherry-maximum rivets from forward and aft bulkheads in excessively tight access panels, I decided to defer the repair. I found the service bulletin xyz, which gives the instruction on installing lanyards. With this company system of deferring items with limits which this task didn't have, I deferred this as deteriorating. After the aircraft left the hangar I found out later it was an airworthiness directive. I wasn't trying to deviate from maintenance, it was something which had to get done. That night we ensured the cannon plugs were going to the correct connectors. Another base corrected this and reported to my supervisor my ill manner of my work. But the station that's reporting me of neglect is the same base who worked in this area and ignored it previously. Callback conversation with reporter revealed the following information: the reporter stated the reporter was working a fire bottle squib check and noticed the connector lanyards were missing. The reporter said since one end of the lanyards required riveting, the reporter decided to enter a deferred item to replace the missing lanyards, being unaware the lanyards were installed by an airworthiness directive and are a no-go item. The reporter stated no publication addressed this problem.
