2012-25-07: Flight controls

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): 2012-25-07 Gulfstream Aerospace Corporation: Amendment 39-17288; Docket No. FAA-2012-1225; Directorate Identifier 2012-NM-219-AD. (a) Effective Date This AD is effective December 17, 2012. (b) Affected ADs None. (c) Applicability This AD applies to Gulfstream Aerospace Corporation Model GIV-X airplanes, certificated in any category, serial numbers 4001 through 4271 inclusive. (d) Subject Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 27, Flight controls. (e) Unsafe Condition This AD was prompted by reports indicating that the flap/ stabilizer electronic control unit (FSECU) does not detect failures of the brake feature within the horizontal stabilizer electric motor unit (HSEMU), or failures of the drive solenoids for hydraulic valves within the flap hydraulic control module (FHCM) during the system power-on self test (SPOST). We are issuing this AD to detect and correct such failures, which could result in runaway horizontal stabilizer pitch trim system and consequent loss of pitch control. (f) Compliance Comply with this AD within the compliance times specified, unless already done. [[Page 74582]] (g) SPOST Within 3 days after the effective date of this AD, perform an SPOST of the FSECU, in accordance with the applicable service information identified in paragraph (h)(1) or (h)(2) of this AD. (1) For Model GIV-X (G350) airplanes: Use Gulfstream G350 Alert Customer Bulletin 11, dated December 4, 2012, excluding Service Reply Card, dated December 4, 2012, and excluding Revision 31, dated December 4, 2012, of the Gulfstream G350 Airplane Flight Manual Document GAC-AC-G350-OPS-0001. (2) For Model GIV-X (G450) airplanes: Use Gulfstream G450 Alert Customer Bulletin 11, dated December 4, 2012, excluding Service Reply Card, dated December 4, 2012, and excluding Revision 33, dated December 4, 2012, of the Gulfstream G450 Airplane Flight Manual Document GAC-AC-G450-OPS-0001. (h) Revision of Aircraft Flight Manual (AFM) Before further flight after the FSECU passes the SPOST required by paragraph (g) of this AD, revise the Normal Procedures and Limitations sections of the AFM to incorporate the information identified in paragraph (g)(1) or (g)(2) of this AD, as applicable. (1) For Model GIV-X (G350) airplanes: Incorporate the information in Section 1-27-40, ``Flap/Stabilizer System Preflight Check,'' and Section 2-03-20, ``Before Starting Engines,'' of the Gulfstream G350 Airplane FlightManual Document GAC-AC-G350-OPS- 0001, Revision 31, dated December 4, 2012.

(2) For Model GIV-X (G450) airplanes: Section 1-27-40, ``Flap/ Stabilizer System Preflight Check,'' and Section 2-03-20, ``Before Starting Engines,'' of the Gulfstream G450 Airplane Flight Manual Document GAC-AC-G450-OPS-0001, Revision 33, dated December 4, 2012.
