Narrative:

While beginning my descent for landing at cxp about chime intersection my passenger said 'what is that?' I saw a drone pass directly off my left wing at less than 50 feet away. I was descending through 8;000' MSL. The operator of the drone is unknown and what it was doing at that altitude is also unknown; but it was where it should not be. This very dangerous situation [that] could have caused a total aircraft loss and or loss of life. I continued the flight without incident. I could not see this drone until I was so close that any evasive action would have been futile.
