This airworthiness directive (AD) is applicable to CFM International (CFMI) CFM56-5C turbofan engines. These engines are installed on, but not limited to, Airbus Industrie A340 airplanes. Note 1: This airworthiness directive (AD) applies to each engine identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For engines that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (d) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it. Compliance Compliance is required as indicated unless already done. To prevent fuel leakage on the hot section or in the primary fire zone of the engine, which may result in an engine fire and subsequent damage to the airplane, do the following: Initial Inspection Requirements (a) Within 10 days after the effective date of this AD, do the following: (1) Inspect the fuel manifold on both sides of the engine for serviceability, and disposition in accordance with paragraphs 3.A. through 3.A.(3) of CFMI ASB CFM56-5C S/B 73-A0106, dated April 19, 2001. (2) Visually inspect harnesses CJ9L and CJ10L for wear. If the wire braid is worn through (pierced), replace the harness within 3,000 hours time-in-service after the first inspection where the wire braid is found to be pierced. (3) Visually inspect and, if necessary, correct the bracket and clamp locations for the CJ10L harness in accordance with paragraphs 3.C. through 3.C.(5) of the Accomplishment Instructions of CFMI ASB CFM56-5C S/B 73-A0106, dated April 19, 2001. Repetitive Inspections (b) Thereafter, repeat the actions required by paragraph (a) of this AD at intervals not to exceed 500 hours time-since-last-inspection.

Alternative Methods of Compliance (d) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Engine Certification Office (ECO). Operators shall submit their requests through an appropriate FAA Maintenance Inspector, who may add comments and then send it to the Manager, ECO. Note 2: Information concerning the existence of approved alternative methods of compliance with this airworthiness directive, if any, may be obtained from the ECO. Special Flight Permits (e) Special flight permits may be issued in accordance with §§ 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the aircraft to a location where the requirements of this AD can be accomplished.
