Narrative:
After amt accomplished eco; reviewed paperwork and also signed that eco did not apply. I missed reading the continuity of steps 3 possibly event was almost 1 yr ago. Could not remember all the details surrounding date and workload in question. Referred eco line by line several times. Possibly steps cold have been idented better. Aircraft was late arrival; workload was normal except for above. I was also handling additional workload from avionics department; deferring their work.
