Narrative:

I performed the removal and installation of the main oil filter of the number 1 engine along with replacing both idg filters and starter oil replenishment. Other maintenance required was the manual deployment of blocker doors for inspection. Installation of main oil filter was performed accordingly to specifications and safety wired with a 5 minute engine run at idle for leak check function. No leaks detected at time of engine run. Evidently proper torque of filter drain plug was not applied before safety wire application (again improperly done) due to complacency and distraction of other maintenance tasks performed on engine at the same time.I was trying to get maintenance done in a timely manner and was doing more than one application at a time; which led to my mistake. The blocker door inspection is a large task which requires 2 individuals to accomplish; and I interrupted my other tasks to accomplish it. I also have a tear on the top of my foot which extends into all joints and bottom plate. I don't want to use this as an excuse; but the constant pain has been causing me distraction.in the future I will be completing one task at a time to ensure that I accomplish my work properly and without distraction or interruption. I have never been involved in the interruption of a flight where passenger's safety was at stake. I do not take this incident lightly and do not want to repeat this event.
