Narrative:

While in cruise initiated right hand banking turn when a bang was felt in control stick. Complete aileron control was lost. Aircraft started a slight left hand roll tendency (approx. 1-degree per second). Attempts to regain control of roll were unsuccessful using aileron. I was able to regain some control and check the roll by using rudder inputs. I then was able to (marginally) able to line up on a private airstrip (3/4 mile away) using only rudder; elevator; and power to land the aircraft without damage to aircraft or property. Upon inspection of aircraft the next day an improper aileron cable nicropress sleeve had let loose causing the loss of control. Inspecting the other cable shows the same type of condition to exist.
