SERIAL Nos AFFECTED All
COMPLIANCE TIME Next scheduled annual inspection
PURPOSE To identify any lateral movement in rudder pedal hinge pins.

First case
Annual inspection of aircraft xxx (DoM 1985), brought to our attention the possibility for the press-fit, shouldered steel hinge pins to work loose in their aluminium housing, rendering pin retention method (interference) ineffective.
ACTION i)Close inspection will allow accurate assessment of hinge pin condition.
In the event that wear is apparent, the rudder hinge (Part F163) must be replaced prior to further flight.

ii)Record the inspection/replacement in the aircraft logbook.
