Airworthiness Directive · Amendment 39-17256 · Powerplant
Airbus Airplanes
Superseded. A later AD replaced this one: AD 2019-21-13. Comply with the one in force.
This AD applies to Airbus Model A330-243, -243F, -341, -342, and -343 airplanes; certificated in any category; all manufacturer serial numbers; equipped with Rolls-Royce Trent 700 engines.
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-243, -243F, -341, -342, and -343 airplanes equipped with Rolls-Royce Trent 700 engines. This AD was prompted by reports of extensive damage to engine air intake cowls as a result of acoustic panel collapse. This AD requires repetitive inspections of the three inner acoustic panels of both engine air intake cowls to detect disbonding, and corrective actions if necessary. We are issuing this AD to detect and correct disbonding, which could result in detachment of the engine air intake cowl from the engine leading to ingestion of parts, which could cause failure of the engine, and possible injury to persons on the ground.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the applicable compliance time specified in paragraph (g)(1) or (g)(2) of this AD: Do a tap test inspection of the three inner acoustic panels of each engine air intake cowl for disbonding, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-71-3024, Revision 01, excluding Appendices 01 through 03, dated September 27, 2011. Repeat the inspection thereafter at intervals not to exceed 24 months, except as required by paragraphs (h) and (i) of this AD.
(1) For an engine air intake cowl that has accumulated less than 5,000 total flight cycles or less than 20,000 total flight hours, whichever occurs first, since its first installation on an airplane as of the effective date of this AD: Within 24 months after the engine air intake cowl has accumulated 5,000 total flight cycles or 20,000 total flight hours, whichever occurs first, since its first installation on an airplane.
(2) For an engine air intake cowl that has accumulated 5,000 or more total flight cycles or 20,000 or more total flight hours, whichever occurs first, since its first installation on an airplane as of the effective date of this AD: Within 24 months after the effective date of this AD.
For airplanes on which an engine air intake cowl is replaced after the effective date of this AD, at the applicable compliance time specified in paragraph (h)(1) or (h)(2) of this AD: Do a tap test inspection for disbonding of the three inner acoustic panels of the affected engine air intake cowl for disbonding, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-71-3024, Revision 01, excluding Appendices 01 through 03, dated September 27, 2011. Repeat the inspection thereafter at intervals not to exceed 24 months.
(1) Within 24 months after the engine air intake cowl accumulates 5,000 total flight cycles or 20,000 total flight hours, whichever occurs first, since its first installation on any airplane, except as required by paragraph (h)(2) of this AD.
(2) Before installation, if an engine air intake cowl has accumulated 5,000 or more total flight cycles or 20,000 or more total flight hours, whichever occurs first, since its first installation on any airplane, and which has not been inspected in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-71-3024, Revision 01, excluding Appendices 01 through 03, dated September 27, 2011, within the preceding 24 months.
(1) If any disbonding is found during any inspection required by this AD, and the findings are within the permitted allowable damage limits (ADLs) specified in Rolls-Royce Non-Modification Service Bulletin RB.211-71-AG419, Revision 1, including Appendix 1, dated May 10, 2011, except as specified in paragraph (j) of this AD: Do the actions specified in paragraph (i)(1)(i), (i)(1)(ii), or (i)(1)(iii) of this AD.
(i) Repeat the tap test inspection required by paragraph (g) of this AD at the applicable inspection interval specified in Rolls-Royce Non-Modification Service Bulletin RB.211-71-AG419, Revision 1, including Appendix 1, dated May 10, 2011, except as specified in paragraph (j) of this AD, until the actions required by paragraph (i)(1)(ii) or (i)(1)(iii) of this AD are accomplished.
(ii) Repair the affected engine air intake cowl before further flight, in accordance with the Accomplishment Instructions of Rolls-Royce Non-Modification Service Bulletin RB.211-71-AG419, Revision 1, including Appendix 1, dated May 10, 2011, except as specified in paragraph (j) of this AD. Repeat the inspection specified in paragraph (g) of this AD thereafter at the applicable compliance time specified in paragraph (g) of this AD.
(iii) Replace the affected engine air intake cowl before further flight, in accordance with the Accomplishment Instructions of Rolls-Royce Non-Modification Service Bulletin RB.211-71-AG419, Revision 1, including Appendix 1, dated May 10, 2011, except as specified in paragraph (j) of this AD. Repeat the inspection specified in paragraph (g) of this AD thereafter at the applicable compliance time specified in paragraph (g) of this AD.
(2) If any disbonding is found during any inspection required by this AD, and the findings are not within the permitted ADLs specified in Rolls-Royce Non-Modification Service Bulletin RB.211-71-AG419, Revision 1, including Appendix 1, dated May 10, 2011, except as specified in paragraph (j) of this AD: Before further flight, replace the affected engine air intake cowl, in accordance with the Accomplishment Instructions of Rolls-Royce Non-Modification Service Bulletin RB.211-71-AG419, Revision 1, including Appendix 1, dated May 10, 2011, except as specified in paragraph (j) of this AD. Repeat the inspection specified in paragraph (g) of this AD thereafter at the applicable compliance time specified in paragraph (g) of this AD.
Although Rolls-Royce Non-Modification Service Bulletin RB.211-71-AG419, Revision 1, including Appendix 1, dated May 10, 2011, specifies to submit certain information to the manufacturer, this AD does not include that 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.
