Narrative:

I was informed that aircraft X was undergoing an A-2 check when it was discovered that the #2 engine oil filter screen was missing. It was determined that I had performed the last documented maintenance on this item. The following statement is my recollection of that event. On may/fri/02, aircraft X arrived at ZZZ with an advisory notice. Replacement of the #2 engine oil filter element, and the forwarding of the removed filter element to power plant engineering at our maintenance facility in ZZZ1. I removed the 32 engine oil filter and inspected it for carbon. Finding none, I replaced it with a new element and completed the installation. Later, after all engine work was accomplished, I ran both engines to check for leaks. None were noted. I have no explanation as to why there was no filter element installed on #2 engine of aircraft X on jun/tue/02, but I am sure that I replaced the one removed on may/fri/02.
