Narrative:

While landing at the grand canyon airport with 19 passenger aboard, I felt some stiffness with the aileron control. After clearing the runway, I tried to duplicate the same feeling of stiffness, but could not feel anything. After the passenger were deplaned, the first officer and I checked the control inside and out, but could find nothing. I then called las dispatch to let them know that I was returning the aircraft to las and would want a complete control system inspection. We flew the aircraft back to las west/O any problems. The inspection turned up a 17' tool punch in the right wing aileron control system. I now understand it would have been better to have had the aircraft inspected at the grand canyon airport. I also believe that company needs a better inspection program. We did not have passenger on board for the return flight.
