2018-12-07: Landing Gear

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 removing Airworthiness Directive (AD) 2015-24-06, Amendment 39-18338 (80 FR 75788, December 4, 2015), and adding the following new AD: 2018-12-07 Gulfstream Aerospace Corporation: Amendment 39-19311; Docket No. FAA-2018-0104; Product Identifier 2017-CE-36-AD. (a) Effective Date This AD is effective July 23, 2018. (b) Affected ADs This AD replaces AD 2015-24-06, Amendment 39-18338 (80 FR 75788, December 4, 2015) (``AD 2015-24-06''). (c) Applicability This AD applies to Gulfstream Aerospace Corporation Model GVI airplanes, serial numbers 6001 and 6003 through 6163, certificated inany category. Note 1 to paragraph (c) of this AD: Model GVI airplanes are also referred to by the marketing designations G650 and G650ER. (d) Subject Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 32, Landing Gear. (e) Unsafe Condition AD 2015-24-06 was prompted by reports of the main landing gear (MLG) self-sealing couplings on the MLG brake inlet fitting backing out of the fully seated position. This AD was prompted by the development of modifications that when incorporated would terminate the need for repetitive breakaway torque checks and torqueing of the brake inlet self-sealing couplings. We are issuing this AD to prevent loss of braking capability on one or multiple brakes. The unsafe condition, if not addressed, could lead to runway overrun or asymmetrical braking that could result in lateral runway excursion. (f) Compliance Comply with this AD within the compliance times specified, unless alreadydone. (g) Modification of the MLG and MLG Brake Assemblies (1) Within 6 months after July 23, 2018 (the effective date of this AD), modify the MLG and brake assemblies following the Accomplishment Instructions in Gulfstream G650 Customer Bulletin Number 155B, dated July 26, 2017; and Gulfstream G650ER Customer Bulletin Number 155B, dated July 26, 2017. (2) Although Gulfstream G650 Customer Bulletin Number 155B, dated July 26, 2017; and Gulfstream G650ER Customer Bulletin Number 155B, dated July 26, 2017, both contain reporting requirements and return of certain parts to the manufacturer, this AD does not include those requirements. (3) AD 2015-24-06 required a dispatch and takeoff limitation in the airplane flight manual. Although we did not retain that requirement in this AD, if not already removed, this limitation should be removed after the modification in paragraph (g)(1) of this AD is done. (h) Credit for Previous Actions If done before July 23, 2018 (the effective date of this AD), this AD allows credit for the actions in paragraph (g) of this AD following Gulfstream G650 Customer Bulletin 155, dated July 29, 2016; Gulfstream G650ER Customer Bulletin 155, dated July 29, 2016; Gulfstream G650 Customer Bulletin 155A, dated August 19, 2016; or Gulfstream G650ER Customer Bulletin 155A, dated August 19, 2016, as applicable. (i) Alternative Methods of Compliance (AMOCs) (1) The Manager, Atlanta ACO Branch, FAA, has the authority to approve AMOCs [[Page 28153]] 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 manager of the certification office, send it to the attention of the person identified in paragraph (j) 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 paragraphs (i)(3)(i) and (ii) 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 the 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.
