Airbus Model A310 Series Airplanes; and Model A300 B4-600, A300 B4-600R, A300 F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
This AD applies to Airbus Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, and F4-622R airplanes; Model A300 C4-605R Variant F airplanes; and Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes; certificated in any category, all certified models, all manufacturer serial numbers.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 130 flight cycles or 650 flight hours after the effective date of this AD, whichever occurs first, measure the thickness of the THSA upper attachment gimbal, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-27A6067, Revision 02, dated October 18, 2010 (for Model A300-600 series airplanes); or A310-27A2104, Revision 02, dated October 18, 2010 (for Model A310 series airplanes).
(1) If, during the measurement required by paragraph (g) of this AD, the gimbal thickness is 58 mm (2.28 in.) +/− 5 mm (0.20 in.), before further flight, do a general visual inspection of the THSA upper attachment to determine if the THSA upper attachment secondary load path is engaged, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-27A6067, Revision 02, dated October 18, 2010 (for Model A300-600 series airplanes); or A310-27A2104, Revision 02, dated October 18, 2010 (for Model A310 series airplanes). Repeat the inspection thereafter at intervals not to exceed 130 flight cycles or 650 flight hours, whichever occurs first, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-27A6067, Revision 02, dated October 18, 2010 (for Model A300-600 series airplanes); or A310-27A2104, Revision 02, dated October 18, 2010 (for Model A310 series airplanes).
(2) If, during the measurement required by paragraph (g) of this AD, the gimbal thickness is not 58 mm (2.28 in.) +/− 5 mm (0.20 in.), except for the requirements of paragraph (l) of this AD, no further action is required of this AD.
(h) If, during any inspection required by paragraph (g)(1) of this AD, the THSA upper attachment secondary load path is found to be engaged, before further flight, contact Airbus for repair instructions and do the repair.
(i) Replacing the gimbal with a “thick” gimbal (70 mm (2.75 in.) +/− 5mm (0.20 in)), in accordance with Goodrich Actuation Systems Component Maintenance Manual with Illustrated Parts List, Horizontal Stabilizer Actuator P/N 47142 Series, Document 27-44-13, Revision 8, dated December 12, 2008, is a terminating action for the requirements of paragraph (g)(1) of this AD, except as required by paragraph (l) of this AD.
Actions accomplished before the effective date of this AD, in accordance with the applicable service bulletins specified in Table 1 of this AD, are considered acceptable for compliance with the corresponding action specified in this AD.

Submit a report of the findings (both positive and negative) of the measurement required by paragraph (g) of this AD to Airbus, as identified in Appendix 01 of Airbus Mandatory Service Bulletin A300-27A6067, Revision 02, dated October 18, 2010 (for Model A300-600 series airplanes); or A310-27A2104, Revision 02, dated October 18, 2010 (for Model A310 series airplanes); at the applicable time specified in paragraph (k)(1) or (k)(2) of this AD. The report must include the information specified in Appendix 01 of Airbus Mandatory Service Bulletin A300-27A6067, Revision 02, dated October 18, 2010 (for Model A300-600 series airplanes); or A310-27A2104, Revision 02, dated October 18, 2010 (for Model A310 series airplanes).
(1) If the measurement was done on or after the effective date of this AD: Submit the report within 30 days after the inspection.
(2) If the measurement was done before the effective date of this AD: Submit the report within 30 days after the effective date of this AD.
As of the effective date of this AD, no person may install, on any airplane, a THSA, unless it is in compliance with the requirements of this AD.
Note 1: This AD differs from the MCAI and/or service information as follows: The MCAI does not include a reporting requirement; however, the service bulletin recommends reporting. Paragraph (k) of this AD specifies a reporting requirement.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
