[Federal Register Volume 80, Number 61 (Tuesday, March 31, 2015)] [Proposed Rules] [Pages 17005-17007] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2015-07301] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-0677; Directorate Identifier 2013-NM-244-AD] RIN 2120-AA64 Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model GVI airplanes. This proposed AD was prompted by reports of corrosion on in-service air non-return valves. This proposed AD would require a revision to the Emergency Procedures section of the airplane flight manual (AFM). This proposed AD would also require a revision to the maintenance or inspection program, as applicable, to incorporate airworthiness limitations for the high pressure (HP) Stage 5 air non-return valves. We are proposing this AD to ensure the flightcrew is provided with procedures to mitigate the risks associated with failure of the HP Stage 5 air non- return valve. Failure of the HP Stage 5 air non-return valve in the open position could result in engine instability and uncommanded in- flight shutdown. DATES: We must receive comments on this proposed AD by May 15, 2015. 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: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2015-0677; Directorate Identifier 2013-NM-244-AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed 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 proposed AD. Discussion We received a report of multiple instances of corrosion on in- service air non-return valves on Gulfstream Aerospace Corporation Model GIV-X airplanes. This corrosion has resulted in failure of air non- return valves. The same part number air non-return valve is installed on the Gulfstream Aerospace Corporation Model GVI airplanes, but it serves a different purpose in that application, where it functions as an HP Stage 5 air non-return valve. Failure of the HP Stage 5 air non-return valve in the open position on the Model GVI airplanes could supply high-stage pressure to the low- stage port, resulting in engine instability and uncommanded in-flight shutdown. This condition could also have an adverse effect on subsequent in-flight engine re-start efforts if the flightcrew follows the current AFM procedures. In light of this information, the FAA has determined that certain procedures should be included in the FAA-approved AFM for Model GVI airplanes to ensure the flightcrew is provided with procedures to mitigate the risks associated with failure of the HP Stage 5 air non- return valve. We have also determined that the maintenance or inspection program, as applicable, should be revised to incorporate an airworthiness limitation for the HP Stage 5 air non-return valves. Related Service Information Under 1 CFR Part 51 We reviewed Section 04-08-20, Normal Airstart-Automatic; Section 04-08-30, Manual Airstart-Starter Assist; and Section 04-08-40, Manual Airstart-Windmilling; of Chapter 04, Emergency Procedures, of the Gulfstream GVI (G650) AFM, Document Number GAC-AC-G650-OPS-0001, Revision 5, dated August 12, 2013. This service information describes revised procedures for in-flight engine restart and operating procedures. In addition, we reviewed Section 05-10-10, Airworthiness Limitations, of Chapter 05, Time Limits/Maintenance Checks, of the Gulfstream GVI (G650) Maintenance Manual (MM), Revision 4, dated September 30, 2013. This service information adds an airworthiness limitation for the HP Stage 5 air non-return valve. This service information is reasonably available; see ADDRESSES for ways to access this service information. FAA's Determination We are proposing 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. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously. This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (j) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane. Interim Action We consider this proposed AD interim action. The manufacturer is currently developing a modification that will positively address the unsafe condition identified in this proposed AD. Once this modification is developed, approved, and available, we might consider additional rulemaking. Costs of Compliance We estimate that this proposed AD affects 52 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- AFM revision....................... 1 work-hour x $85 per hour $0 $85 $4,420 = $85. MM revision........................ 1 work-hour x $85 per hour 0 85 4,420 = $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. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the [[Page 17007]] distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify this proposed regulation: (1) Is not a ``significant regulatory action'' under Executive Order 12866, (2) Is not a ``significant rule'' under the 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
