[Federal Register Volume 80, Number 196 (Friday, October 9, 2015)] [Rules and Regulations] [Pages 61088-61091] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2015-25495] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-0677; Directorate Identifier 2013-NM-244-AD; Amendment 39-18289; AD 2015-20-10] RIN 2120-AA64 Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model GVI airplanes. This AD was prompted by reports of corrosion on in-service air non-return valves. This AD requires a revision to the Emergency Procedures section of the airplane flight manual (AFM). This AD also requires 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 issuing this AD to ensure the flightcrew is provided with [[Page 61089]] 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: This AD is effective November 13, 2015. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of November 13, 2015.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Gulfstream Aerospace Corporation Model GVI airplanes. The NPRM published in the Federal Register on March 31, 2015 (80 FR 17005). The NPRM was prompted by reports of corrosion on in-service air non-return valves. Failure of the HP Stage 5 air non-return valve in the open position could result in engine instability and uncommanded in-flight shutdown. The NPRM proposed to require a revision to the Emergency Procedures section of the AFM and a revision to the maintenance or inspection program, as applicable, to incorporate airworthiness limitations for the HP Stage 5 air non-return valves. We are issuing 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. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (80 FR 17005, March 31, 2015) or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM (80 FR 17005, March 31, 2015) for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the (NPRM 80 FR 17005, March 31, 2015). Interim Action We consider this AD interim action. The manufacturer is currently developing a modification that will positively address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, we might consider additional rulemaking. 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 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. Costs of Compliance We estimate that this AD affects 52 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 ---------------------------------------------------------------------------------------------------------------- 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 [[Page 61090]] 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.

(e) Unsafe Condition This AD was prompted by reports of corrosion on in-service air non-return valves. We are issuing this AD to ensure the flightcrew is provided with procedures to mitigate the risks associated with failure of the high pressure (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. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Revision of the Airplane Flight Manual (AFM) Within 30 days after the effective date of this AD: Revise the Emergency Procedures section of the AFM by inserting 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.
