ACTION: Final rule; request for comments. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation (Gulfstream) Model GVI airplanes. This AD requires revising the Normal and Abnormal Procedures sections of the airplane flight manual (AFM). This AD was prompted by potential failure of the bi-directional data bus that sends and receives critical signals between the flight control computer (FCC) and the flight control surfaces. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective October 15, 2018. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 15, 2018. We must receive comments on this AD by November 13, 2018.

SUPPLEMENTARY INFORMATION: Discussion On Gulfstream Model GVI airplanes, the FCC and the remote electronics unit (REU) communicate with each other by means of bi- directional data buses, referred to as BD429. Gulfstream notified us that loss of bi-directional (Transmit/Receive) BD429 communication, due to wire/connector failures, between the REU and the FCC would result in the display of a cyan ``FCS MAINTENANCE REQUIRED'' advisory message on the crew alerting system (CAS). Because this cyan advisory message does not directly indicate that BD429 communication has failed, the aircraft can be dispatched with this advisory message. The Model GVI system depends on the BD429 bus to assure signal transmission to address a linear variable differential transformer (LVDT) disconnect monitor and/ or surface oscillatory monitor event. During recent developmental testing, Gulfstream discovered that certain BD429 failures prevent the shutdown of a flight control surface that would normally occur during an oscillatory or LVDT disconnect event. The only indication of the failure is a cyan ``FCS MAINTENANCE REQUIRED'' advisory message on the CAS. If the FCC cannot receive information from the REU that a particular flight control surface had an event, then the FCC cannot issue a command to place that particular flight control surface into standby/damped bypass mode. The REU will still receive flight control commands from the FCC via the secondary (receive only) bus; however, because the secondary bus is receive-only for certain REUs, the FCC will no longer receive REU data needed for the LVDT disconnect monitor and/or surface oscillatory monitor for the impacted flight control surface. This condition (results in a cyan CAS message, but does not indicate the exact reason) can remain latent for up to one year. To date, there have been no known events or failures of the BD429 communications bus wiring or connectors in the field. However, the Gulfstream GVI fleet has experienced multiple in-flight flight control events requiring a standby command sent over the BD429 bus to keep the airplane safe. Since the GVI system uses these monitors to mitigate potentially unsafe failure modes, dispatch with their loss leaves the aircraft one failure away from a potential loss of control event. This condition, if not addressed, could result in the FCC's inability to identify when a problematic flight control surface needs to be damped, which could result in loss of control of the airplane. Related Service Information Under 1 CFR Part 51 We reviewed Gulfstream Aerospace G650 AFM Supplement No. G650-2018- 01, dated August 14, 2018; and Gulfstream Aerospace G650ER AFM Supplement No. G650ER-2018-01, dated August 14, 2018. For each applicable airplane configuration, the AFM supplement provides instructions and warnings to the Normal Procedures and Abnormal Procedures section of the AFM for the pilot to follow if a cyan ``FCS MAINTENANCE REQUIRED'' CAS message displays with the airplane on the ground or in flight. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. FAA's Determination We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. [[Page 48919]] AD Requirements This AD requires revising the Normal and Abnormal Procedures sections of the AFM by adding instructions and warnings for the pilot if a cyan ``FCS MAINTENANCE REQUIRED'' CAS message displays with the airplane on the ground or in flight. Interim Action We consider this AD interim action. Gulfstream is analyzing the failures and working to develop a terminating action that will address the unsafe condition identified in this AD. Once this action is developed, approved, and available, we might consider additional rulemaking. FAA's Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because the inability of the FCC to send a standby command when the BD429 bus is in a failed state could leave the airplane with only one level of protection from a catastrophic flight control failure. Therefore, we find good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reason stated above, we find that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this final rule. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA-2018- 0870 and Product Identifier 2018-CE-047-AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this final rule. We will consider all comments received by the closing date and may amend this final rule because of those comments. We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this final rule. Costs of Compliance We estimate that this AD affects 213 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Revise Gulfstream AFM............. 1 work-hour x $85 per Not applicable....... $85 $18,105 hour = $85. ---------------------------------------------------------------------------------------------------------------- Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ``Subtitle VII: Aviation Programs'' describes in more detail the scope of the Agency's authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: ``General requirements.'' Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to small airplanes, gliders, balloons, airships, domestic business jet transport airplanes, and associated appliances to the Director of the Policy and Innovation Division. Regulatory Findings This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a ``significant regulatory action'' under Executive Order 12866, (2) Is not a ``significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska, and (4) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
