ACTION: Final rule; request for comments. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model GVI airplanes. This AD requires repetitive breakaway torque checks and torqueing of the brake inlet self-sealing couplings. This AD also requires revising the airplane flight manual to include procedures to follow in the event of certain display indications. This AD was prompted by reports of the self- sealing couplings on the brake inlet fitting that have been found backed out of the fully seated position. We are issuing this AD to detect and correct inadequate torque on the self-sealing coupling. This condition could result in an unannounced total loss of braking capability on one or multiple brakes, which could result in a runway overrun or asymmetrical braking that can lead to a lateral runway excursion. DATES: This AD is effective December 4, 2015. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of December 4, 2015. We must receive comments on this AD by January 19, 2016. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

SUPPLEMENTARY INFORMATION: Discussion We have received reports of self-sealing couplings on the brake inlet fitting that have been found backed out of the fully seated position. Due to the function of these couplings, this issue allows for the self-sealing mechanism to activate and cut off hydraulic pressure to the brake caliper, resulting in reduced or no braking ability on the affected wheel while the brake pressure indications remain normal on the flight deck indicators. Multiple coupling failures may lead to loss of braking capability on more than one wheel, creating the potential for loss of aircraft braking effectiveness on one or multiple brakes. Since the flight deck brake pressure indications would appear normal under these conditions, the crew will have no indications other than the loss of braking control on one or [[Page 75789]] multiple brakes. Unannounced total loss of braking capability on one or multiple brakes, could result in a runway overrun or asymmetrical braking that can lead to a lateral runway excursion. Related Service Information Under 1 CFR Part 51 Gulfstream has issued G650 Alert Customer Bulletin 4A, dated November 13, 2015; and G650ER Alert Customer Bulletin 4A, dated November 13, 2015. The service information describes procedures for a breakaway torque check and torqueing the brake inlet self-sealing couplings. 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 of this AD. 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. AD Requirements This AD requires accomplishing the actions specified in the service information described previously, except as discussed under ``Difference Between the AD and the Service Information.'' Difference Between the AD and the Service Information Although Gulfstream G650 Alert Customer Bulletin 4A, dated November 13, 2015; and G650ER Alert Customer Bulletin 4A, dated November 13, 2015; recommend that the breakaway torque check and torqueing the brake inlet self-sealing couplings be repeated only one time, this AD requires repetitive accomplishment of the checks and torqueing of the brake inlet self-sealing coupling at intervals not to exceed 100 flight cycles. We have determined repetitive actions are necessary to address the identified unsafe condition. We have coordinated this difference with Gulfstream. Interim Action We consider this AD interim action. The manufacturer is currently developing a modification that will address the unsafe condition identified in this AD and would terminate the repetitive actions in this AD. Once this modification 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. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because an unannounced total loss of braking capability on one or multiple brakes can cause a runway overrun or asymmetrical braking that can lead to a lateral runway excursion. Therefore, we find that notice and opportunity for prior public comment are impracticable and 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 AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA-2015-6546 and Directorate Identifier 2015-NM-179-AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD 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 AD. Explanation of ``RC'' Steps in Service Information The FAA worked in conjunction with industry, under the Airworthiness Directive Implementation Aviation Rulemaking Committee (ARC), to enhance the AD system. One enhancement was a new process for annotating which steps in the service information are required for compliance with an AD. Differentiating these steps from other tasks in the service information is expected to improve an owner's/operator's understanding of crucial AD requirements and help provide consistent judgment in AD compliance. The steps identified as Required for Compliance (RC) in any service information identified previously have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition. For service information that contains steps that are labeled as RC, the following provisions apply: (1) 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, and an AMOC is required for any deviations to RC steps, including substeps and identified figures; and (2) 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. Costs of Compliance We estimate that this AD affects 120 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Action Labor cost Cost per product Cost on U.S. operators ---------------------------------------------------------------------------------------------------------------- Breakaway torque check and torqueing 2 work-hours x $85 per $170 per check/torque $20,400 per check/ of inlet self-sealing couplings. hour = $170 per check/ cycle. torque cycle. torque cycle. AFM revision......................... 1 work-hour x $85...... $85.................... $10,200. ---------------------------------------------------------------------------------------------------------------- According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, [[Page 75790]] 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. 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.
