If an IDG is shut down automatically on or after the effective date of this AD, do the actions specified in paragraph (k) of this AD.

(1) Before further flight, inspect the firewall connector of the affected IDG to detect signs of arcing, in accordance with a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA. If any sign of arcing is detected: Before further flight, either repair the connector or replace the connector with a new connector, in accordance with a method approved by the Manager, International Branch, ANM-116.

(2) Operate the airplane with the affected IDG inoperative in accordance with the provisions and compliance periods specified in the FAA-approved Master Minimum Equipment List or in accordance with a method approved by the Manager, International Branch, ANM-116. Before further use of the affected IDG, do the actions specified in paragraph (h)(1) of this AD. As of the effective date of this AD, operate the airplane in accordance with a method approved by the Manager, International Branch, ANM-116.

Note 1: Guidance on provisions and compliance periods for operating the airplane with an inoperative, affected IDG can be found in the FAA-approved Master Minimum Equipment List.

(i) For Airbus Model A319-131, -132, and -133; A320-231, -232, and -233; and A321-131 and -231 series airplanes, except those airplanes on which Airbus Modification 32943 has been incorporated in production: Replacement of the IDG harnesses and connectors on both engines in accordance with Airbus Service Bulletin A320-71-1030, dated February 27, 2003, before the effective date of this AD terminates the requirements of paragraphs (g) and (h) of this AD.

Note 2: Airbus Service Bulletin A320-71-1030, dated February 27, 2003, refers to International Aero Engines Information Bulletin V2500-NAC-70-0736, dated January 28, 2003, as an additional source of guidance for the harness/connector replacement specified in paragraph (i) of this AD.

For all airplanes: Within 10 days after the effective date of this AD, revise the applicable section of the Airbus A318/319/320/321 AFM to include the information in Figure 1 of this AD or the information in Airbus TR TR112, Issue 1.1, dated November 29, 2010, to the Airbus A318/319/320/321 AFM. This may be done by inserting a copy of this AD or Airbus TR TR112, Issue 1.1, dated November 29, 2010, in the AFM. Accomplishing the actions required by this paragraph terminates the requirements of paragraph (g) of this AD.

Note 3: When the information in Figure 1 of this AD or Airbus TR TR112, Issue 1.1, dated November 29, 2010, to the Airbus A318/319/320/321 AFM, has been included in the applicable section of the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD may be removed from the AFM, provided the relevant information in the general revisions is identical to that in Figure 1 of this AD or Airbus TR TR112, Issue 1.1, dated November 29, 2010.

For all airplanes: If an IDG is shut down by the flightcrew in accordance with the TR procedures specified in paragraph (j) of this AD, or if an IDG is shut down automatically on or after the effective date of this AD, do the actions specified in paragraph (k)(1) or (k)(2) of this AD.

(1) Before further flight, inspect the firewall connector of the affected IDG to detect signs of arcing, in accordance with a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA. If any sign of arcing is detected: Before further flight, either repair the connector or replace the connector with a new connector, in accordance with a method approved by the Manager, International Branch, ANM-116.

Note 4: Guidance on provisions and compliance periods for operating the airplane with an inoperative, affected IDG can be found in the FAA-approved Master Minimum Equipment List.

Note 5: This AD differs from the MCAI and/or service information as follows: The MCAI does not require inspecting an IDG that has been shut down in accordance with Airbus TR TR112, Issue 1.1, dated November 29, 2010, or that has been shut down automatically. We have determined that investigative and corrective actions (including an inspection for signs of arcing, and repair or replacement of any discrepant IDG harness/connector with a new harness/connector) are necessary due to the severity of the problem to prevent the unsafe condition from recurring. The inspections and corrective actions must be done in accordance with a method approved by Manager, International Branch, ANM-116.
