You are allowed to perform these tasks as long as you have the current Manufacturer’s Service Manual (eg.-Airframe/Engine), proper tooling (eg.- torque wrench) along with proper documented training. Your local AME/AMO can teach you how to perform Elementary Tasks and have this documented somewhere. Now you can perform these tasks on your own! CARs STD 571.02
