2012-22-12: Powerplant

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new AD: 2012-22-12 Airbus: Amendment 39-17248. Docket No. FAA-2012-0428; Directorate Identifier 2011-NM-078-AD. (a) Effective Date This airworthiness directive (AD) becomes effective December 14, 2012. (b) Affected ADs None.

(d) Subject Air Transport Association (ATA) of America Code 71, Powerplant. (e) Reason This AD was prompted by reports of cracking of air intake cowls on Rolls-Royce Trent engines, worn and detached attachment links, and fractured thermal anti-ice (TAI) piccolo tubes. We are issuing this AD to prevent degraded structural integrity of the engine nose cowl in case of forward bulkhead damage in conjunction with a broken piccolo tube, and damage to the engine due to operation in icing conditions with reduced TAI performance. (f) Compliance You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. (g) Piccolo Tube Inspection At the applicable time specified in paragraph (g)(1) or (g)(2) of this AD, do a boroscope inspection of each air intake cowl assembly of each engine to detect cracked or fractured piccolo tubes, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-71-3025, excluding Appendices 01 and 02, dated January 10, 2011. If any cracked or fractured piccolo tube is found: Before further flight, replace the affected engine air intake cowl with a new or serviceable engine air intake cowl, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-71-3025, excluding Appendices 01 and 02, dated January 10, 2011. (1) For any engine air intake cowl that has accumulated fewer than 5,000 flight cycles since its first installation on an airplane as of the effective date of this AD: Inspect within 24 months after the engine air intake cowl has accumulated 5,000 total flight cycles. (2) For any engine air intake cowl that has accumulated 5,000 or more flight cycles since its first installation on an airplane as of the effective date of this AD: Inspect within 24 months after the effective date of this AD. (h) Piccolo Link Inspection If the inspection findings of paragraph (g) of this AD indicate no cracked or fractured piccolo tube: Before further flight, do a boroscope inspection of the piccolo tube links to detect brokenlinks, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-71-3025, excluding Appendices 01 and 02, dated January 10, 2011. If no broken links are found: Before further flight, do the actions required by paragraph (i) of this AD. (1) If four or more broken piccolo tube links are found: Before further flight, replace the affected engine air intake cowl with a new or serviceable engine air intake cowl, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-71-3025, excluding Appendices 01 and 02, dated January 10, 2011. (2) If three or fewer broken piccolo tube links are found, and the opposite engine air intake cowl of the same airplane has accumulated 5,000 flight cycles or less since the engine air intake cowl was first installed on an airplane: Before further flight, do the actions in Figure A-FBBAA-Sheet 03, Flow Chart, of Airbus Mandatory Service Bulletin A330-71-3025, excluding Appendices 01 and 02, dated January 10, 2011, as required by paragraph (i) of this AD.
