  (b) If a crack is found during an inspection required by paragraph (a) of this AD, before further flight, repair and reinforce the rear wing spar adjacent to the inboard and outboard aileron hinge attachments in accordance with paragraphs (c) and (d) of the "INSTRUCTIONS" section of SIAI Marchetti Service Bulletin No. 205B42, dated January 3, 1976, or an FAA- approved equivalent, except that, for SIAI Marchetti Model S205 airplanes, S/N's 101 through 222, 224, 228, 229, 231, 232, and 233, the reinforcement provisions of paragraph (c) of the Service Bulletin need not be accomplished.
