Narrative:
Removed only 1/2 of the mechanical locks on the left and right engine thrust reversers (l-hand locks on each engine). I was not aware of each engine having 2 lockouts. Supplemental information from acn 733565: inspected only half of the removal of thrust reverser mechanical locks on l-hand and r-hand engines. Not aware that each engine has 2 lockouts per engine.
