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): 2017-26-05 Gulfstream Aerospace Corporation: Amendment 39-19136; Docket No. FAA-2017-0910; Product Identifier 2017-CE-027-AD. (a) Effective Date This AD is effective January 25, 2018. (b) Affected ADs None. (c) Applicability This AD applies to Gulfstream Aerospace Corporation Model G- 1159A (GIII), serial number (S/N) 460; Model G-IV, S/Ns 1129, 1151, 1167, 1175, 1214, and 1380; and Model GIV-X (G450), S/Ns 4118 and 4227 airplanes. (d) Subject Joint Aircraft System Component (JASC)/Air Transport Association (ATA)of America Code 57, Wings. (e) Unsafe Condition This AD was prompted by a report that certain flap tracks were manufactured with the upper flange thickness less than design minimum. We are issuing this AD to prevent deformation or failure of a flap track that could cause flap actuator failure, ``B track'' roller overload, flap twisting/failure, or asymmetrical flap track failure. This failure could result in an unrecoverable roll. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Replace Flap Track C Within the next 6 months after January 25, 2018 (the effective date of this AD), replace the flap track C on the left side, part number (P/N) 1159WM20052-105, and/or the flap track C on the right side, P/N 1159WM20052-106, with an airworthy part. Accomplish the replacements following Gulfstream III Customer Bulletin Number 187, Gulfstream G450 Customer Bulletin Number 195, or Gulfstream IV Customer Bulletin Number 240, all dated June 28, 2017, as applicable. (h) Reporting Requirement Although Gulfstream III Customer Bulletin Number 187, Gulfstream G450 Customer Bulletin Number 195, and Gulfstream IV Customer Bulletin Number 240, all dated June 28, 2017, specify to submit certain information to the manufacturer, this AD does not require that action. (i) Special Flight Permit Special flight permits under 14 CFR 39.23 are allowed with the following limitation: Do not extend 39 degrees (FULL) flaps until airspeed is at or below 170 knots. (j) Alternative Methods of Compliance (AMOCs) (1) The Manager, Atlanta ACO 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 [[Page 60507]] District Office, as appropriate. If sending information directly to the manager of the ACO Branch, send it tothe attention of the person identified in paragraph (k) of this AD. (2) 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. (3) For service information that contains steps that are labeled as Required for Compliance (RC), the provisions of paragraph (g) of this AD apply. (i) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with this AD. An AMOC is required for any deviations to RC steps, including substeps and identified figures. (ii) Steps not labeled 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 RC steps, including substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition.
