Narrative:
On jul/xa-xb/08 aircraft was in ZZZ for a line check; #1 propeller grease level check and other scheduled items. I performed the grease level inspection; found the level was satisfactory and only put the bolt in hand-tight and not torqued. This was not found until jul/xa/08 during an 'a' check. I was later informed by e-mail from my supervisor and lead on jul/xb/08 after my wkend. Pictures were also provided in the e-mail. Other than I missed up; I would say it was complacency due to an almost nightly requirement for grease level inspection. Pay more attention.
