that have been subjected to the referenced MRB task since aeroplane delivery.  This MRB lubrication task is only scheduled from 5 years.

             Note 2:  Rotary actuators Type B in leading edge slats are not affected by the deletion of this MRB repetitive lubrication task contained in Requirement 3.

             Note 3:  DGAC AD F-2005-067 EASA approval No.3629 dated 20 April 2005 refers.  This directive supersedes DGAC AD 2003-121(B).
Compliance:  For Requirement 1, excluding 1(a) & (b):  Remains unchanged as detailed in the original issue of this Directive as; unless previously accomplished, carry out within 1,000 flight hours after 7 August 2003.  (The effective date of the original issue of this Directive.)

             For Requirement 1(a):  Remains unchanged as detailed in the original issue of this Directive as, within 7,500 flight hours after 7 August 2003.

             For Requirement 1(b):  At intervals not exceeding 7,500 flight hours.

             For Requirement 2:  Not later than 2,500 flight hours after the required repetitive inspection.

             For Requirement 3:  From the effective date of this Directive.

             For Requirement 4:  At the latest by 30 June 2008.
             This Amendment becomes effective on 4 August 2005.
Background:  During a scheduled check on an A340 an excessive leak at the torque limiter output shaft seal of the rotary actuator Type A of leading edge slat No.1 was reported.  Investigations by the supplier of the actuator found that parts of the torque limiter were totally contaminated with grease that had migrated from the power gear stage after re-greasing.  Such contamination could cause the linkage drive to jam and lead to structural damage with a potential for loss of slat No1 leading edge.  This AD is intended to prevent the possible loss of slat No1 leading edge.

             This amendment introduces a requirement to replace certain actuators with no change to the previous requirements.

   The original issue of this AD became effective on 7 August 2003.
