             This Airworthiness Directive becomes effective on 30 August 2007.
Background:  This AD results from reports of broken or cracked damper shafts within the aileron and elevator actuator assemblies.  The issuing of this AD is to prevent broken damper shafts, which could result in locking of an aileron or elevator actuator (hard-over condition), which would activate the hard-over protection system (HOPS), resulting in increased pilot workload and consequent reduced controllability of the aeroplane.
