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 removing Airworthiness Directive (AD) 2016-13-06, Amendment 39-18570 (81 FR 41432, June 27, 2016), and adding the following new AD: 2018-18-17 Saab AB, Saab Aeronautics (Formerly Known as Saab AB, Saab Aerosystems): Amendment 39-19396; Docket No. FAA-2018-0271; Product Identifier 2017-NM-111-AD.

(c) Applicability This AD applies to Saab AB, Saab Aeronautics (Type Certificate Previously Held by Saab AB, Saab Aerosystems) airplanes, certificated in any category, as identified in paragraphs (c)(1) and (c)(2) of this AD. (1) Saab AB, Saab Aeronautics Model 340A (SAAB/SF340A) airplanes, serial numbers (S/Ns) 004 through 138 inclusive, on which Saab Modification 1462 has been embodied in production, or Saab Service Bulletin 340-55-008 has been embodied in service, except those on which Saab Modification 1793 has also been embodied in production, or Saab Service Bulletin 340-55-010 has been embodied in service; and Saab AB, Saab Aeronautics Model 340A (SAAB/SF340A) airplanes, S/Ns 139 through 159 inclusive. (2) Saab AB, Saab Aeronautics Model SAAB 340B airplanes, S/Ns 160 through 459 inclusive. (d) Subject Air Transport Association (ATA) of America Code 30, Ice and Rain Protection. (e) Reason This AD was prompted by reports of ruptured horizontal stabilizer de-icing boots. We are issuing this AD to detect and correct ruptured horizontal stabilizer de-icing boots, which could lead to complete loss of the deicing function within its associated zone and severe vibrations, possibly resulting in reduced control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Retained Revision of the Airplane Flight Manual (AFM), With No Changes This paragraph restates the requirements of paragraph (g) of AD 2016-13-06, with no changes. Within 30 days after August 1, 2016 (the effective date of AD 2016-13-06), revise the ``Abnormal Procedures'' section of the applicable Saab 340 AFM to incorporate the revision specified in paragraphs (g)(1) through (g)(3) of this AD. (1) For Saab AB, Saab Aeronautics Model 340A (SAAB/SF340A) airplanes, revise Saab AFM 340A 001 by incorporating Revision 57, dated March 27, 2015. (2) For Saab AB, Saab Aeronautics Model SAAB 340B airplanes, revise Saab AFM 340B 001 by incorporating Revision 35, dated March 27, 2015. (3) For Saab AB, Saab Aeronautics Model SAAB 340B airplanes with extended wing tips, revise Saab AFM 340B 010 by incorporating Revision 28, dated March 27, 2015. (h) Retained Inspection/Replacement, With No Changes This paragraph restates the requirements of paragraph (h) of AD 2016-13-06, with no changes. Within 400 flight hours or 6 months, whichever occurs first after August 1, 2016 (the effective date of AD 2016-13-06), do a detailed inspection for damage of the horizontal stabilizer de-icing boots, and existing repairs of horizontal stabilizer de-icing boots, in accordance with the Accomplishment Instructions of Saab Service Bulletin 340-30-094, dated March 27, 2015. Repeat the inspection thereafter at intervals not to exceed 400 flight hours. If, during any inspection required by this paragraph, any damage or existing repair outside the limits specified in Saab Service Bulletin 340-30-094, dated March 27, 2015, is found, before further flight, repair or replace the horizontal stabilizer de-icing boots, in accordance with the Accomplishment Instructions of Saab Service Bulletin 340-30-094, dated March 27, 2015. Repair or replacement on an airplane of the horizontal stabilizer de-icing boots, as required by this paragraph, does not constitute terminating action for the repetitive inspections required by this paragraph for that airplane.
