    (i) The elevator assembly guide for distortion: and

    (ii) The welded seam of the elevator assembly guide, using a 5 power magnifier, for cracks.

  (b) If, during the inspection required by paragraph (a) of this AD, a crack or distortion of the elevator assembly guide is found, before further flight, comply with paragraph (d).

  (c) If, during the inspection required by paragraph (a) of this AD, a crack or distortion of the elevator assembly guide is not found, within the next 100 hours' time in service after the effective date of this AD, unless already accomplished, comply with paragraph (d).

  (d) When compliance is required by paragraph (b) or (c), replace the elevator actuator bracket with a serviceable elevator actuator bracket reinforced with two sheet metal strips in accordance with paragraph 4 of the "Method" section of Glasflugel Technical Note No. 201-20, 205-6, 206-1, 301-30 dated July 11, 1975, or an FAA-approved equivalent.
