2018-23-05: Wings

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 airworthiness directive (AD): 2018-23-05 Airbus SAS: Amendment 39-19491; Docket No. FAA-2018-0958; Product Identifier 2018-NM-139-AD. (a) Effective Date This AD becomes effective November 23, 2018. (b) Affected ADs None. (c) Applicability This AD applies to the Airbus SAS airplanes, certificated in any category, identified in paragraphs (c)(1) and (c)(2) of this AD. (1) Model A350-941 airplanes, manufacturer serial numbers (MSNs) 203, 205, 208, 209, 210, 212, 213, 218, 219, 221, 227, 228, and 235. (2) Model A350-1041 airplanes, MSN 188. (d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Reason This AD was prompted by a report of a close gap between the wing lower cover (WLC) and wing rib feet. We are issuing this AD to address potential contact between the WLC and wing rib feet, which, combined with an empty fuel tank or fuel level below the wing rib foot area, could create an ignition source for the fuel vapor inside the tanks. In case of a lightning strike of high intensity in the immediate area, this condition could possibly result in ignition of the fuel-air mixture in the affected fuel tank and consequent loss of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Minimum Equipment List (MEL) Revision Within 30 days after the effective date of this AD, revise the operator's MEL to prohibit dispatch of the airplane with any inoperative MEL item listed in figure 1 to paragraphs (g) and (i) of thisAD. 4910-13-P ------------------------------------------------------------------------ Sequence No. Item ------------------------------------------------------------------------ 21-09-01...............................

(1) If any discrepancy is detected, do all applicable related investigative and corrective actions before further flight, in accordance with Airbus Alert Operators Transmission A57P011-18, dated October 8, 2018. (2) If any structural damage is detected, before further flight obtain corrective actions approved by the Manager, International Section, Transport Standards Branch, FAA; or the European Aviation Safety Agency (EASA); or Airbus SAS's EASA Design Organization Approval (DOA) and accomplish the corrective actions within the compliance time specified therein. If approved by the DOA, the approval must include the DOA-authorized signature. (i) Relief From MEL Restrictions After accomplishment of the inspection and all applicable related investigative and corrective actions required by paragraph (h) of this AD on an operator's fleet, the MEL revision specified in paragraph (g) of this AD is no longer required by this AD, and the provisions for relief for the affected MEL items in figure 1 to paragraphs (g) and (i) of this AD may be restored, provided those items are not otherwise restricted by the existing master minimum equipment list (MMEL). (j) Reporting Provisions Although Airbus Alert Operators Transmission A57P011-18, dated October 8, 2018, specifies sending inspection results to Airbus, this AD does not require a report. (k) Other FAA AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Section, Transport Standards Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the International Section, sendit to the attention of the person identified in paragraph (l)(2) of this AD. Information may be emailed to [email protected]. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/certificate holding district office. (2) Contacting the Manufacturer: For any requirement in this AD to obtain corrective actions from a manufacturer, the action must be accomplished using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or EASA; or Airbus SAS's EASA DOA. If approved by the DOA, the approval must include the DOA- authorized signature. (3) Required for Compliance (RC): If any service information contains procedures or tests that are identified as RC, those procedures and tests must be done to comply with this AD; any procedures or tests that are not identified as RC are recommended. Those procedures and tests that are not identified as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the procedures and tests identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures or tests identified as RC require approval of an AMOC.
