2010-20-04: Flight controls

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. Effective Date (a) This airworthiness directive (AD) becomes effective October 28, 2010. Affected ADs (b) None. 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. Subject (d) Air Transport Association (ATA) of America Code 27: Flight controls. Reason (e) The mandatory continuing airworthiness information (MCAI) states: Extension of airbrakes above 360 KIAS [knots indicated air speed]/0.79 Mi [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 failureof 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. 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. 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. ``MAXIMUM AIR BRAKES OPERATION/EXTENDED SPEED 360 KIAS/0.79 Mi NOTE During emergency, air brakes may be used at speeds above 0.79 Mi.'' 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. 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.
