On landing, the PIC who was flying from the right-hand side, lost directional control of the aircraft which then veered off the runway and struck a fence on the aerodrome boundary. The pilot reported that it seemed that they had no rudder control, as it f elt like the rudder pedals had locked up. The aircraft was also not fitted with dual toe brakes, which may have assisted with directional control, had they been fitted. Contact with the fence caused significant damage to the wing's leading edges and to the nose undercarriage. There were no injuries. An inspection of the aircraft following the accident failed to find any defects with the rudder control system.
