Background:	This AD results from an incident of jamming of the aileron and rudder controls on a Model SR20 aeroplane.  In addition, other Models SR20 and SR22 aeroplanes have been found with misrigging of the flight controls that could lead to jamming.  The issuing of this AD is intended to prevent the possibility of jamming of the rudder-aileron interconnect system, which may result in loss of rudder and aileron flight controls.
