 Eurocopter AS 350 (Ecureuil) Series Helicopters

 AD/ECUREUIL/61 Amdt 1 (continued)

2.c.   With-in 25 flying hours from detection of the misalignment.

            Note 2: Compliance to the original version of AD/ECUREUILl/61 is an acceptable alternate to this amendment and no further action is required.

            This Amendment becomes effective on 23 December 2004.

            Background: This amendment of the Airworthiness Directive reflects changes in the document referred to, in the original issue of the AD, namely revision 1 of Eurocopter AS 350 ASB 05.00.33 and revision 1 of DGAC AD F-2000-222-079. The changes are in the effectivity list and there is no difference in the technical contents.

            There have been reports of rotation of the bearing spacers in AS350 tail rotor. Such rotation indicates that the inner bearing race may be rotating on its shaft. Rotation may cause excessive wear and cut the rotating plate, which will cause deterioration and loss of pitch control of the tail rotor.

            The original issue of the directive addressed unsafe condition caused by the loss of pitch control of the tail rotor.

            The original issue of this Airworthiness Directive became effective on 14 June 2000.
