    1. SUBTASK 72-38-11-350-065 Remove the Damaged Strip Seals from the Inlet Cone Fairing

    1. Refer to Figure.

    2. Examine and identify damaged strip seal of the inlet cone fairing.

      3. Remove damaged strip seal without any damage to the parent metal and remove the remaining compound.

    2. SUBTASK 72-38-11-230-055 Examine the Inlet Cone Fairing for Cracks

      1. Do a crack test on the repaired area.

        1. Make sure there are no cracks in the repair area.

        1. Refer to the SPM TASK 70-23-02-230-501.

        2. Use penetrant crack test equipment.

    3. SUBTASK 72-38-11-360-071 Prepare the Mating Surfaces for the Silicone Rubber Compound

    1. Refer to Figure.

      2. Prepare the strip seal(s).

        1. Use the 5A1255 strip seal.

        1. Cut the strip seal to the dimensions given in the figure.

      3. Install the fairing onto the locating fixture.

    4. Check and determine the mating surface area of the fairing using strip seal.

    5. Remove the fairing from the locating fixture.

      6. Degrease the mating surfaces of the fairing and strip seal.

      7. Hand clean the mating surfaces of the fairing and strip seal.

      2. Refer to SPM TASK 70-36-02-360-501.

      8. Degrease the mating surfaces of the fairing and strip seal.

    4. SUBTASK 72-38-11-360-072 Apply and Cure the Cold Curing Silicone Rubber Compound

    1. Refer to Figure.

      2. CAUTION

        AFTER PREPARATION THE MATING SURFACES MUST BE FULLY CLEANED AND MUST NOT BE TOUCHED BY HAND, TO PREVENT CONTAMINATION.

        CAUTION

        DO NOT APPLY THE PRIMER TO THE MATING SURFACE OF THE STRIP SEAL.

        NOTE

        The primer must be applied immediately after the mating surfaces are prepared.
        If the parts are not used immediately, after the primer is applied, they must be kept in polythene bags but for not longer than 24 hours.

        Apply a thin layer of primer only to the prepared mating surfaces of the fairing. Dry in the air for 30 minutes.

      2. Refer to the SPM TASK 70-36-02-360-501, SUBTASK 70-36-02-360-020.

      3. NOTE

        Install the strip seal to the fairing within three minutes after the compound is applied.

        Apply the cold curing silicone rubber compound to each of the mating surfaces.

      1. Use a spatula and CoMat 08-013 COLD CURING SILICONE COMPOUND cold curing silicone rubber compound.

      2. Refer to the SPM TASK 70-36-02-360-501, SUBTASK 70-36-02-360-020.

      4. Install the fairing onto the locating fixture.

    5. Install the strip seal(s) on the fairing.

      6. Clamp the strip seal(s) and fairing with clips during curing.

      1. Use washing clip or equivalent.

    7. Remove the fairing with strip seal from the locating fixture.

      8. Remove excess adhesive compound from the fairing and strip seal(s).

      1. Make sure that the compound can be seen around the sealed surfaces. Use a scraper.

    9. NOTE

      The parts can be touched after 12 hours.

      Cure the compound at room temperature for 48 hours.

    10. Remove the clips from the fairing.

    5. SUBTASK 72-38-11-220-172 Examine the Repaired areas of the Inlet Cone Fairing

    1. Refer to Figure.

    2. Dimensionally examine the position of the repaired strip seal(s).

    3. Visually examine gapping and filling.

    6. SUBTASK 72-38-11-350-066 Identify the Repair

      1. Mark the VRS1057 adjacent to the part number.

      1. Use the electrolytic etch method.

      2. Refer to the SPM TASK 70-09-00-400-501.
