2018-20-04: Flight Controls

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): 2018-20-04 Gulfstream Aerospace Corporation: Amendment 39-19438; Docket No. FAA-2018-0870; Product Identifier 2018-CE-047-AD. (a) Effective Date This AD is effective October 15, 2018. (b) Affected ADs None. (c) Applicability This AD applies to Gulfstream Aerospace Corporation Model GVI airplanes, all serial numbers, certificated in any category. (d) Subject Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 27, Flight Controls. [[Page 48920]] (e) Unsafe ConditionThis AD was prompted by the potential for an un-annunciated failure of the bi-directional data bus that sends critical signals from the flight control computer to the flight controls. This unsafe condition, if not addressed, could result in the flight control computer's inability to identify when a problematic flight control surface needs to be damped, which could result in loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Airplane Flight Manual Revisions Within 30 days after October 15, 2018 (the effective date of this AD), revise the Normal Procedures and Abnormal Procedures sections of the airplane flight manual by adding the information in Gulfstream Aerospace G650 Airplane Flight Manual Supplement No. G650-2018-01, dated August 14, 2018; or Gulfstream Aerospace G650ER Airplane Flight Manual Supplement No. G650ER-2018-01, dated August 14, 2018; as applicable to the model configuration of your airplane.

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 (i) of this AD.
