[Federal Register Volume 82, Number 124 (Thursday, June 29, 2017)] [Rules and Regulations] [Pages 29368-29371] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-13405] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2016-9437; Directorate Identifier 2016-NM-131-AD; Amendment 39-18941; AD 2017-13-11] 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 Model G-IV airplanes. This AD was prompted by a report indicating that the G-IV gust lock system allows more throttle travel than was intended and could allow the throttle to be advanced to reach take-off thrust. This AD requires modification of the gust lock system, and a revision of the maintenance or inspection program to incorporate functional tests. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective August 3, 2017. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 3, 2017. ADDRESSES: For service information identified in this final rule, contact Gulfstream Aerospace Corporation, Technical Publications Dept., P.O.

FOR FURTHER INFORMATION CONTACT: Gideon Jose, Aerospace Engineer, Systems and Equipment Branch, ACE-119A, FAA, Atlanta Aircraft Certification Office (ACO), 1701 Columbia Avenue, College Park, GA 30337; phone: 404-474-5569; fax: 404-474-5606; email: [email protected]. 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 G-IV airplanes. The NPRM published in the Federal Register on December 12, 2016 (81 FR 89397) (``the NPRM''). The NPRM was prompted by a report indicating that the G-IV gust lock system allows more throttle travel than was intended and could allow the throttle to be advanced to reach take-off thrust. The intended function of the gust lock system is to restrict throttle lever movement to a maximum of 6 degrees of forward travel, which provides an unmistakable warning to the pilot that the gust lock system is still engaged, prohibiting the use of the primary flight control surfaces. The NPRM proposed to require modification of the gust lock system, and a revision of the maintenance or inspection program to incorporate functional tests. We are issuing this AD to prevent the throttle lever movement from advancing more than 6 degrees of forward travel, which could result in the aircraft reaching near take-off thrust and high velocities without primary flight [[Page 29369]] controls (aileron, elevator, and rudder) and cause a failure to rotate during take-off and high speed runway overrun. Comments We gave the public the opportunity to participate in developing this AD. We have considered the comment received. The commenter, the National Transportation Safety Board (NTSB), supported the NPRM. New Service Information Since we issued the NPRM, we received the following customer bulletins that clarify the modification instructions, and we have revised paragraph (g) of this AD to refer to these bulletins:Gulfstream IV Customer Bulletin Number 236B, dated February 3, 2017; Gulfstream G300 Customer Bulletin Number 236B, dated February 3, 2017; and Gulfstream G400 Customer Bulletin Number 236B, dated February 3, 2017. We have also added the following customer bulletins to paragraph (k) of this AD to provide credit for the actions required by paragraph (g) of this AD if those actions were performed before the effective date of this AD: Gulfstream IV Customer Bulletin Number 236A, dated August 8, 2016; Gulfstream G300 Customer Bulletin Number 236A, dated August 8, 2016; and Gulfstream G400 Customer Bulletin Number 236A, dated August 8, 2016. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these minor changes: Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed the following customer bulletins: Gulfstream IV Customer Bulletin Number 236B, dated February 3, 2017; Gulfstream G300 Customer Bulletin Number 236B, dated February 3, 2017; and Gulfstream G400 Customer Bulletin Number 236B, dated February 3, 2017. The service information describes procedures for modifying the gust lock system by doing a retrofit of the gust lock throttle interlock. These documents are distinct since they apply to different airplane models in different configurations. We also reviewed the following temporary revisions (TRs): Gulfstream IV Maintenance Manual TR 27-3, dated April 29, 2016; Gulfstream IV MSG-3 Maintenance Manual TR 27-3, dated April 29, 2016; Gulfstream G300 Maintenance Manual TR 27-3, dated April 29, 2016; and Gulfstream G400 Maintenance Manual TR 27-3, dated April 29, 2016. The service information describes procedures for a functional test of the throttle lever gust lock protection. These documents are distinct since they apply to different airplane models in different configurations. We also reviewed the following temporary revisions: Gulfstream IV Maintenance Manual TR 5-7, dated April 29, 2016; Gulfstream IV MSG-3 Maintenance Manual TR 5-6, dated April 29, 2016; Gulfstream G300 Maintenance Manual TR 5-3, dated April 29, 2016; and Gulfstream G400 Maintenance Manual TR 5-3, dated April 29, 2016. The service information describes an airworthiness limitation (certification maintenance requirement) task to do functional tests of the throttle lever gust lock protection. These documents are distinct since they apply to different airplane models in different configurations. 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. Costs of Compliance We estimate that this AD affects 425 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 ---------------------------------------------------------------------------------------------------------------- Modification and Maintenance or 109 work-hours x $85 per $9,080 $18,345 $7,796,625 Inspection Program Revision. hour = $9,265. ---------------------------------------------------------------------------------------------------------------- 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, 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), [[Page 29370]] (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.
