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): 2017-25-13 Airbus: Amendment 39-19127; Docket No. FAA-2017-0627; Product Identifier 2017-NM-037-AD. (a) Effective Date This AD is effective January 22, 2018. (b) Affected ADs None. (c) Applicability This AD applies to Airbus Model A330-201, -202, -203, -223, - 223F, -243, -243F, -301, -302, -303, -321, -322, -323, -341, -342 and -343 airplanes; and Airbus Model A340-211, -212, -213, -311, - 312, -313, -541, and -642 airplanes; certificated in any category, all manufacturer's serial numbers. (d) Subject Air Transport Association (ATA) of America Code 27, Flight Controls. (e) Reason This AD was prompted by a report that the trimmable horizontal stabilizer actuator (THSA) might not function as intended after failure of the primary load path. We are issuing this AD to detect and correct discrepancies of the THSA upper attachments and no-back housing, which could lead to THSA upper attachment failure and consequent disconnection of the THSA from the airplane structure, possibly resulting in loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Repetitive Detailed Visual Inspections Before exceeding the threshold in Table 1 to paragraph (g) of this AD, as applicable, or within 3 months after the effective date of this AD, whichever occurs later; and thereafter at intervals not to exceed the inspection interval values defined in Table 1 to paragraph (g) of this AD; accomplish a detailed visual inspection for discrepancies of the THSA upper attachments and no-back housing, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A330-27-3218, Revision 01, A340-27-4203, Revision 01, or A340-27-5067, Revision 01, all dated December 5, 2016, as applicable. Where the ``Threshold'' column of table 1 to paragraph (g) of this AD specifies compliance times in ``FH'' (flight hours) or ``FC'' (flight cycles), those compliance times are flight hours or flight cycles since the first flight of the airplane, or since the last accomplishment of Airbus Model A330 or A340 Maintenance Review Board Report task 27.40.00/07, or since the last detailed visual inspection of the THSA done in accordance with the Accomplishment Instructions of Airbus Service Bulletin A330-27-3218, Revision 00, A340-27-4203, Revision 00, or A340-27-5067, Revision 00, all dated July 1, 2016, as applicable.
