Human Factors
While turning right base to final at ZZZ for Runway XX; Pilot Flying and I noticed what appeared to be a quad-rotor drone off our right wing approximately 500 feet away; and 100 feet below our altitude. We believe the drone was at approximately 600 feet altitude. This was reported to ZZZ Tower via radio and subsequent phone call to the Tower Manager. He took a lot of information from us about the events for a report on his end. A drone was flying in controlled airspace near final approach for Runway XX. It didn't appear to be in cooperation with ZZZ ATC control.
Air taxi pilot reported a UAS passed by their aircraft when approaching to land. The pilot continued the approach and landed normally.
