        a. Do a detailed inspection of the identified actuator to detect a broken damper shaft, in accordance with the applicable customer bulletin.

        For the purposes of this AD, a detailed inspection is: "An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity.  Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate.  Inspection aids such as mirror, magnifying lenses, etc., may be necessary.  Surface cleaning and elaborate procedures may be required.''

        b. If no damper shaft is found broken, Repeat the inspection detailed in Requirement 3a. of this AD.

           (i) Replace the actuator with a new or serviceable actuator having a P/N and S/N listed in Table 1 "Serial Number Effectivity Table'' of the applicable customer bulletin, provided the new or serviceable actuator has been inspected in accordance with the Requirement 3 of this AD.  Thereafter, repeat the inspection detailed in Requirement 3 of this AD for that actuator.

           (ii) Replace the actuator with a new or serviceable actuator having a new P/N listed in Table 2 "Retrofit Part Number Replacement Table'' of the applicable customer bulletin.  This replacement terminates the requirements detailed in Requirement 3 of this AD for that actuator only.

      4. Replace all identified suspect actuators with new or serviceable actuators having a new P/N listed in Table 2 "Retrofit Part Number Replacement Table'' of the applicable customer bulletin.  This replacement terminates the requirements of this AD, except as detailed in Requirement 5 of this AD.

                5. Do not install an aileron or elevator actuator having a P/N and S/N specified in the applicable customer bulletin on any aeroplane, unless the actuator has been inspected according to Requirement 3 of this AD.

                6. Special flight permits are not allowed if any broken damper shaft is found during any inspection detailed in Requirement 3 of this AD.
