This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Extension of airbrakes above 360 KIAS [knots indicated air speed]/0.79 M i [Mach indicated] results in aerodynamic driven vibration of the airbrake which, if not limited per Revision 14 to the AFM [airplane flight manual], can lead to high cycle fatigue failure of the airbrake in-board hinge. ## The airworthiness directive ### Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: 1. The authority citation for part 39 continues to read as follows: 2. The FAA amends § 39.13 by adding the following new AD: 2010-20-04 Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.): Amendment 39-16438. Docket No. FAA-2010-0555; Directorate Identifier 2010-NM-053-AD. ### (a) Effective Date (a) This airworthiness directive (AD) becomes effective October 28, 2010. ### (b) Affected ADs (b) None. ### (c) Applicability (c) This AD applies to Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Galaxy and Gulfstream 200 airplanes, all serial numbers, certificated in any category. ### (d) Subject (d) Air Transport Association (ATA) of America Code 27: Flight controls. ### (e) Reason (e) The mandatory continuing airworthiness information (MCAI) states: Extension of airbrakes above 360 KIAS [knots indicated air speed]/0.79 M i [Mach indicated] results in aerodynamic driven vibration of the airbrake which, if not limited per Revision 14 to the AFM [airplane flight manual], can lead to high cycle fatigue failure of the airbrake in-board hinge. The unsafe condition is high cycle fatigue of the airbrake in-board hinge, which can result in loss of the airbrake, which in turn can lead to reduced controllability of the airplane. ### (f) Compliance (f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. ### (g) Actions (g) Within 60 days after the effective date of this AD: Revise the Limitations section of the Gulfstream 200 AFM to include the following statement. This may be done by inserting a copy of this AD into the AFM. ### NOTE During emergency, air brakes may be used at speeds above 0.79 M i. ” Note 1: When a statement identical to that in paragraph (g) of this AD has been included in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD may be removed from the AFM. Note 2: The Gulfstream 200 AFM applies to both the Model Galaxy and Gulfstream 200 airplanes. ### FAA AD Differences Note 3: This AD differs from the MCAI and/or service information as follows: No differences. ### (h) Other FAA AD Provisions (h) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Mike Borfitz, Aerospace Engineer, International Branch, ANM-116, Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone (425) 227-2677; fax (425) 227-1149. Before using any approved AMOC on any airplane to which the AMOC applies, notify your principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office. The AMOC approval letter must specifically reference this AD. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056. ### (i) Related Information (i) Refer to MCAI Israeli Airworthiness Directive 01-10-01-07R1, dated January 20, 2010, for related information. ### (j) Material Incorporated by Reference (j) None. ## Rule preamble ### Dates This AD becomes effective October 28, 2010. ### Addresses You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC. ### For further information contact Mike Borfitz, Aerospace Engineer, International Branch, ANM-116, Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone (425) 227-2677; fax (425) 227-1149. ### Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on June 25, 2010 (75 FR 36296). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Extension of airbrakes above 360 KIAS [knots indicated air speed]/0.79 M i [Mach indicated] results in aerodynamic driven vibration of the airbrake which, if not limited per Revision 14 to the AFM [airplane flight manual], can lead to high cycle fatigue failure of the airbrake in-board hinge. The unsafe condition is high cycle fatigue of the airbrake in-board hinge, which can result in loss of the airbrake, which in turn can lead to reduced controllability of the airplane. The required action includes revising the Limitations section of the Gulfstream 200 Airplane Flight Manual to prohibit deploying the air brakes above the stated speed. You may obtain further information by examining the MCAI in the AD docket. ### Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. ### Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. ### Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a NOTE within the AD. ### Costs of Compliance We estimate that this AD will affect about 90 products of U.S. registry. We also estimate that it will take about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $7,650, or $85 per product. ### 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 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 this AD: 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); and 3. 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. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. ### Examining the AD Docket You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information.
