2017-20-08: Airborne Auxiliary Power and Fuselage

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 removing Airworthiness Directive (AD) 2009-17-01, Amendment 39-15991 (74 FR 40061, August 11, 2009), and adding the following new AD: 2017-20-08 Gulfstream Aerospace Corporation: Amendment 39-19065; Docket No. FAA-2016-9522; Product Identifier 2016-NM-144-AD. (a) Effective Date This AD is effective November 6, 2017. (b) Affected ADs This AD replaces AD 2009-17-01, Amendment 39-15991 (74 FR 40061, August 11, 2009) (``AD 2009-17-01''). (c) Applicability This AD applies to the Gulfstream Aerospace Corporation airplanes, certificated [[Page 45709]] in any category, identified in paragraphs (c)(1) through (c)(5) of this AD. (1) Model G-IV airplanes, having serial numbers (S/Ns) 1000 and subsequent. (2) Model GIV-X airplanes, having S/Ns 4001 and subsequent. (3) Model GV airplanes, having S/Ns 501 and subsequent. (4) Model GV-SP airplanes, having S/Ns 5001 and subsequent. (5) Model GVI airplanes, having S/Ns 6001 and subsequent. (d) Subject Air Transport Association (ATA) of America Code 49, Airborne Auxiliary Power; and 53, Fuselage. (e) Unsafe Condition This AD was prompted by a report indicating that the type design sealant (Aerospace Material Specification (AMS) 3374), as applied to the auxiliary power unit (APU) enclosure (firewall), does not meet the requirement in 14 CFR 25.1191(b)(1) for a firewall to be fireproof, and failed a certification test and a company test. We are issuing this AD to provide the flight crew with operating procedures for airplanes that have AMS 3374 or Gulfstream Material Specification (GMS) 4107 sealant applied to the APU enclosure. Under certain anomalous conditions such as an APU failure/APU compartment fire, AMS 3374 or GMS 4107 sealant could ignite the exterior surfaces of the APU enclosure and result in propagation of an uncontained fire to other critical areas of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Airplane Flight Manual (AFM) Revision Within 30 days after the effective date of this AD, revise the Limitations Section of the applicable Gulfstream AFM specified in paragraphs (h)(1) through (h)(6) of this AD to include the information in the applicable Gulfstream AFM supplement (AFMS) specified in paragraphs (h)(1) through (h)(6) of this AD. These AFMSs introduce operating limitations on the use of the APU during certain ground and flight operations. This AFM revision may be done by inserting a copy of the applicable AFMS into the applicable AFM specified in paragraphs (h)(1) through (h)(6) of this AD. When the AFMS has been included in the general revision of the AFM, the general revision may be inserted into the AFM, provided the relevant information in the general revision is identical to that in the applicable AFMS specified in paragraphs (h)(1) through (h)(6) of this AD. (h) AFMSs For the AFM revision required by paragraph (g) of this AD, insert the applicable AFMS into the applicable Gulfstream AFM identified in paragraphs (h)(1) through (h)(6) of this AD.
