        With a view to removing any traces of corrosion and improving the protective treatment at the half-shell-to-stabiliser tube centre section assembly points, the following measures were to have been applied at the 400 flight hour interval or by 13 February 1989, whichever occurred first.

        Carry out the checks and any required reworking, return the assembly to airworthy condition and mark the letter "X" on the stabiliser in accordance with paragraph C.1. of Eurocopter Service Bulletin (SB) No. 01.25.

        a. Accomplishment of a visual inspection in accordance with paragraph 2.B(1) of SB No. 55.01 Revision 2, was required within 3 months after
        14 December 1996.

        If corrosion is detected inside the tube, other than in the half-shell area, replacement of the tube was required within 500 flight hours or by
        31 December 1998, whichever occurred first.

        b. A check, and if necessary, modification of the supports and the stabiliser was required by 14 June 1997 in accordance with paragraph 2.B.(2) of SB No. 55.01 Revision 2 (embodiment of modification 07.2215), provided that the instructions in paragraph 2.B.(3) of SB No. 55.01 Revision 2 were applied once within 8 days or 10 flight hours, whichever occurred first, from the effective date of DGAC AD 96-277-037(A) R1 dated 21 May 1997 (A check of the condition of the tube inside the area which is covered by the two half-shells.  If a crack is found, discard the tube).

        c. Once compliance with Requirement 2.b. is confirmed, accomplish the following:

           (i) Visually check the installation of the half-shells and the horizontal stabiliser.

           (ii) Visually check the condition of the installation and lubricate the spar tube attachment bolts.

                  d. Embodiment of modification 07.2214 (installation of spar tube without play) was to have been accomplished by 1 March 1984, as required by DGAC AD 83-204-026(B) (which has been cancelled).

                  e. For the horizontal stabilisers part number 315A35-10-000-2, the airworthiness aspects covered by DGAC AD 85-194-030(B) effective 27 November 1985, which is superseded and replaced by 96-277-037(A) R2 (this AD), remain applicable. These aspects are as follows:

                  Confirm that there are no traces of marking on the spar tube and rework the stabiliser support fittings in accordance with paragraph C.1. of SB No. 01.23.

                3. STABILISERS – ALL PART NUMBERS

                Attach lockwire to the four attachment clamps of the half-shells in accordance with paragraph 2.B.2 of SB No. 55.01 Revision 4.

                All stabilisers held as spares must be modified before installation on an aircraft, by the embodiment of modifications 07.2214 and 07.2215; and the inside of the tube visually inspected in accordance with paragraph 2.B.(1) of SB No. 55.01 Revision 4.
