(1) If the bolts are installed correctly, no further action is required by paragraph (a) of this AD. (2) If any bolt is found to have been incorrectly installed, prior to further flight, correct its installation and perform a functional test of the landing gear free fall control and emergency extension systems in accordance with the AOT.

(b) Within 7 days after accomplishing the detailed visual inspection required by paragraph (a) of this AD, submit a report of any inspection findings to Airbus Industrie, in accordance with Airbus Industrie AOT 32-06, dated March 3, 1993.
