AD/HU 369/84 Tail Rotor Blades  1/92 DM

            Applicability: Model 369 Series fitted with the following tail rotor blades: P/N 369D21613
            S/Ns 0646, 1165,1821.

            P/N 369D21613M S/Ns 1357, 1809, 1855. P/N 369D21613-11 S/Ns 2465, 2466, 2683. P/N 369D21613-51
            S/Ns 4025, 4026, 4453, 4514, 4515, 4683, 02222-6097. P/N 369D21613-501
            S/N 5308.

            Requirement: Remove from service any tail rotor blade identified by the above serial number listing.

            Note 1: Removed blades need to be returned to Rotor Blades (NZ) Ltd for rework. Note 2: Air Transport NZ AD DCA/HU 369/59 refers.
 Compliance: Unless already accomplished; prior to further flight after 20 November 1991.

            Background: This Directive is issued in response to a NZ AD which was issued as the result of a recent accident in New Zealand where a tail rotor blade abrasion strip separated in flight. Initial investigation has indicated a defect with the tail rotor blade abrasion strip attachment. The abrasion strips may appear free of bond separation or voids, but this does not assure their airworthiness. The above identified tail rotor blades are of the same batch as the accident blade.
