             This Amendment becomes effective on 11 September 2007.
Background:  EASA was informed by the manufacturer of an in-flight incident in which a dynamic weight broke off the control lever subsequently leading to considerable vibrations.  A visual inspection revealed that the threaded bolt of the control lever had broken off. For this reason, the manufacturer issued ASB MBB BK117 C-2-64A-002 to introduce a corresponding visual inspection.

             EASA subsequently issued Emergency AD 2006-0379-E to require operators to accomplish the inspection.  The aim of that EAD was to prevent separation of dynamic weights in flight, which can lead to severe vibration and reduced controllability of the helicopter.

             This amendment mandates the replacement of certain parts and provides terminating action to the repetitive inspections detailed in this AD.

             The original issue of this AD became effective on 30 August 2007.
