 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2005-22528; Directorate Identifier 2005-NM-125-AD]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A318-100 and A319-100 series airplanes; A320-111 airplanes; A320-200 series airplanes; and A321-100 and A321-200 series airplanes. This proposed AD would require a one-time inspection of the horizontal hinge pin of the 103VU electrical panel in the avionics compartment to determine if the hinge pin can move out of the hinge, and related investigative and corrective actions if necessary. This proposed AD results from a report indicating that electrical wire damage was found in the 103VU electrical panel due to contact between the hinge pin and the adjacent electrical wire harness. We are proposing this AD to prevent contact between the horizontal hinge pin and the adjacent electrical wire harness, which could result in damage to electrical wires, and consequent arcing and/or failure of associated systems.
 DATES: We must receive comments on this proposed AD by October 27, 2005.

                    rale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, notified the FAA that an unsafe condition may exist on certain Airbus Model A318-100 and A319-100 series airplanes; A320-111 airplanes; A320-200 series airplanes; and A321-100 and A321-200 series airplanes. The DGAC advises that electrical wire damage was found in the 103VU electrical panel, which is located in the avionics compartment. Investigation revealed contact between the horizontal hinge pin and an adjacent electrical wire harness, due to migration of the hinge pin. This condition, if not corrected, could result in damage to electrical wires, and consequent arcing and/or failure of associated systems. Relevant Service Information Airbus has issued All Operators Telex (AOT) 25A1440, dated February 15, 2005. The AOT describes procedures for inspecting the 103VU electrical panel horizontal hinge pin to determine if the pin can move out of the hinge. If there is no hinge movement, the AOT states that no further action is required. If there is movement, the AOT states that operators should do the related investigative action of inspecting for damage to the adjacent electrical harness, and do all necessary corrective actions. The corrective actions include reworking the hinge, and repairing any damage to the electrical harness. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DGAC mandated the AOT and issued French airworthiness directive F-2005-052 R1, dated April 13, 2005, to ensure the continued airworthiness of these airplanes in France. FAA's Determination and Requirements of the Proposed AD These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. We have examined the DGAC's findings, evaluated all pertinent information, and determined that we need to issue an AD for products of this type design that are certificated for operation in the United States. Therefore, we are issuing this AD to require accomplishing the actions specified in the service information described previously. 
                    ( print page 56382) Clarification of Inspection Language The service bulletin and the French airworthiness directive request that operators “inspect” for hinge pin movement. This proposed AD defines that inspection as a “general visual inspection.” This inspection is defined in Note 1 of this AD.

 Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority. We are issuing this rulemaking under the authority described in subtitle VII, part A, subpart III, section 44701, “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that the proposed regulation: 1. Is not a “significant regulatory action” under Executive Order 12866; 2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and 3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. See the 
                    **ADDRESSES**

 The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: Authority:
                        49 U.S.C. 106(g), 40113, 44701. § 39.13
  2. The Federal Aviation Administration (FAA) amends § 39.13 by adding the following new airworthiness directive (AD): **Airbus:**
                                 Docket No. FAA-2005-22528; Directorate Identifier 2005-NM-125-AD. Comments Due Date (a) The FAA must receive comments on this AD action by October 27, 2005. Affected ADs (b) None. Applicability (c) This AD applies to Airbus Model A318-111 and -112; A319-111, -112, -113, -114, -115, -131, -132, and -133; A320-111, -211, -212, -214, -231, -232, and -233; and A321-111, -112, -131, -211 and -231 airplanes; certificated in any category; serial numbers (S/Ns) 1 through 2396 inclusive, except S/Ns 2104, 2143, 2248, 2270, 2347, 2366, 2372, 2376, 2384, 2386, 2388, 2390, 2391, 2393, and 2395. Unsafe Condition (d) This AD results from a report indicating that electrical wire damage was found in the 103VU electrical panel due to contact between the hinge pin and the adjacent electrical wire harness. The FAA is issuing this AD to prevent contact between the horizontal hinge pin and the adjacent electrical wire harness, which could result in damage to electrical wires, and consequent arcing and/or failure of associated systems. Compliance (e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Inspections and Corrective Actions (f) Within 600 flight hours after the effective date of this AD, do a general visual inspection of the horizontal hinge pin of the 103VU electrical panel in the avionics compartment to determine if the pin can move out of the hinge, and do any applicable related investigative and corrective actions, including repair of any damaged electrical wires, before further flight. Do all the actions in accordance with Airbus All Operators Telex 25A1440, dated February 15, 2005. Note 1: For the purposes of this AD, a general visual inspection is: “A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to ensure visual access to all surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.” No Reporting (g) Although All Operators Telex 25A1440, dated February 15, 2005, specifies that operators should send the results of inspections to the manufacturer, that action is not required by this AD. Alternative Methods of Compliance (AMOCs) (h)(1) The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19. (2) Before using any AMOC approved in accordance with § 39.19 on any airplane to which the AMOC applies, notify the appropriate principal inspector in the FAA Flight Standards Certificate Holding District Office. Related Information (i) French airworthiness directive F-2005-052 R1, dated April 13, 2005, also addresses the subject of this AD.
