Background: There have been instances of failure of the pilot’s rudder bar due to fractures of the central pillar/slider tube, adjacent to the welded transverse lugs. This defect had not appeared in the co-pilot’s (or dual) rudder bar installation and these dual rudder bar assemblies were exempt from examination at Issue 1 of the Requirement document. Following a recent discovery of this defect in a co-pilot’s rudder bar installation, Issue 2 of the Requirement document includes both left and right hand assemblies.
