After completing the final manoeuvre of a display sequence, an aileron roll at 600 ft agl, the aircraft continued to roll and pitch nose-down despite the pilot’s control inputs. The pilot reduced power and declared a MAYDAY. The pilot identified a restriction in the rudder controls which, after vigorous movement of all of the flying controls, cleared. The pilot regained control of the aircraft at 50 ft agl and, after turning the aircraft back towards the airfield, completed an uneventful emergency landing.
An inspection of the aircraft, carried out immediately after the flight, showed that the flying controls appeared to operate normally and were undamaged. A detailed inspection of the aircraft completed a few days after the event confirmed that there were no defects with the flying controls. However, a partially crushed pen was found within the fuselage. The damage to the pen indicated that it was the probable cause of the control restriction. The pilot reported that, prior to the incident flight, a pen top had been recovered from the rear cockpit of the aircraft during the pre-flight loose article check but no other articles had been seen.
