2013-11-09: Fuel injection manifolds and the privilege injector

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) 2001-08-14R1, Amendment 39 14423 (71 FR 2993, January 19, 2006), and adding the following new AD: * * * * * 2013-11-09 Turbomeca S.A.: Amendment 39 17469; Docket No. FAA-2013- 0024; Directorate Identifier 2000-NE-12-AD. (a) Effective Date This AD is effective July 5, 2013. (b) Affected ADs This AD supersedes AD 2001-08-14R1, Amendment 39 14423 (71 FR 2993, January 19, 2006). (c) Applicability This AD applies to all Turbomeca S.A. Arrius 2B1 and 2F turboshaft engines. (d) Unsafe Condition This AD was prompted by a report that the corrective actions of AD 2001-08-14R1, Amendment 39 14423 (71 FR 2993, January 19, 2006) were insufficient to eliminate the unsafe condition. We are issuing this AD to prevent an uncommanded in-flight shutdown of Arrius 2B1 and 2F turboshaft engines and damage to the helicopter. (e) Compliance Comply with this AD within the compliance times specified, unless already done. (f) Arrius 2B1 Turboshaft Engines (1) Replace the fuel injector manifolds and privilege injector with parts eligible for [[Page 32553]] installation before exceeding 200 operating hours, time-since-new (TSN). (2) Borescope-inspect the flame tube and the high-pressure turbine area for turbine distress, when replacing the fuel injection manifolds and privilege injector for the first time. (3) Thereafter, within every 200 operating hours, time-in- service (TIS) since last fuel injector manifolds and privilege injector replacement, or sooner if a power check performed per flight manual ECT135-T1 indicates a negative T45 margin, replace the fuel injector manifolds and the privilege injector with parts eligible for installation. (g) Arrius 2F Turboshaft Engines (1) Replace the privilege injector with a privilege injector eligible for installation before exceeding 400 operating hours TSN. (2) Borescope-inspect the flame tube and the high-pressure turbine area for turbine distress, when replacing the privilege injector for the first time. (3) Thereafter, within every 400 operating hours TIS since last privilege injector replacement, replace the privilege injector with parts eligible for installation. (h) Definition For the purposes of this AD, TIS is defined as: (1) The number of engine operating hours on the manifolds since the manifolds were new or since the manifolds were last cleaned, whichever is more. (2) The number of engine operating hours on the privilege injector since the privilege injector was new or since the privilege injector was last cleaned, whichever is more. (i) Installation Prohibitions (1) For Arrius 2B1 turboshaft engines, after the effective date of this AD, do not install fuel injector manifolds or a privilege injector on an engine, or an engine on a helicopter, unless the fuel injection manifold and privilege injector have accumulated fewer than 200 operating hours since new, or since last inspection. (2) For Arrius 2F turboshaft engines, after the effective date of this AD, do not install a privilege injector on an engine, or an engine on a helicopter, unless the privilege injector has accumulated fewer than 400 operating hours since new, or since last inspection. (j) Alternative Methods of Compliance (AMOCs) The Manager, Engine Certification Office, may approve AMOCs for this AD. Use the procedures found in 14 CFR 39.19 to make your request.
