Narrative:
At XA30; aircraft came in. The aircraft required an oil check and a repair on the l-hand protective lens missing. I performed the oil check using part 135 amm 12-12-01 and installed the protective lens using part 135 amm 57-30-01. Aircraft flew 2 legs and came back with l-hand lens missing. Callback conversation with reporter revealed the following information: the reporter stated the lens reported missing was the left landing light lens which protects the light lamp. The right lens is the same material and construction but r-hand confign.
