Narrative:

After reinstalling propeller, after it had been svced, aircraft was ground run and shut down for inspection. Found ok. Then flew aircraft around traffic pattern, shut down and again inspected propeller installation. After inspecting ok, I flew the aircraft approximately 30 mins. I later returned the same day for approximately 1 hour of flight. While reviewing propeller installation procedures later in the evening, I noticed that the installation of propeller must be accomplished by an a&P mechanic. I am working under the supervision of an a&I, but have not received an a&P rating yet. Although the work performed was noted in aircraft logbook, the aircraft was not technically airworthy for flight, during the flts noted above. I notified my a&I, who inspected the propeller installation and signed off the work performed in the aircraft logbook, and returned the aircraft to an airworthy flight condition.
