             This Airworthiness Directive becomes effective on 24 September 2009.
Background:  This AD results from eight instances of cracks in CCHs.  Two of the instances resulted in an engine shutdown during flight.  The issuing of this AD is intended to detect cracks in the CCH, which could result in rupture of the CCH, leading to loss of engine power and damage to the helicopter.
