AD 2006-03-10

The FAA is adopting 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 AD requires 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 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 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.

Final rule.

2006-03-10 Airbus: Amendment 39-14474. Docket No. FAA-2005-22528; Directorate Identifier 2005-NM-125-AD.

Effective Date

(a) This AD becomes effective March 16, 2006.

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. We are 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 Airbus 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 Sec. 39.19on any airplane to which the AMOC applies, notify the appropriate principal inspector in the FAA Flight Standards Certificate Holding District Office.

(i) French airworthiness directive F-2005-052 R1, dated April 13, 2005, also addresses the subject of this AD.

Material Incorporated by Reference

(j) You must use Airbus All Operators Telex 25A1440, dated February 15, 2005, to perform the actions that are required by this AD, unless the AD specifies otherwise. The Director of the Federal Register approved the incorporation by reference of this document in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to 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. That NPRM was published in the Federal Register on September 27, 2005 (70 FR 56381). That NPRM proposed to 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.

Comments

We provided the public the opportunity to participate in the development of this AD. We have considered the comment received.

Statement of Planned Revision to French Airworthiness Directive

The commenter, the airplane manufacturer, notes that the French airworthiness directive F-2005-052 R1, dated April 13, 2005, which was cited in the NPRM, will be revised to add Airbus Modification 36115 as the final fix for the unsafe condition. The commenter notes that the purpose of Airbus Modification 36115 is to ensure that the hinge is manufactured to prevent hinge pin migration.

We infer that the commenter is requesting that we consider mandating this modification when the Direction Generale de l'Aviation Civile (DGAC) revises French airworthiness directive F- 2005-052. We will consider mandating this modification after the DGAC releases its revision. However, we will not delay issuing this AD pending release of the new French airworthiness directive and the applicable Airbus service bulletin. Operators may request an alternative method of compliance under the provisions of paragraph (h) of this AD. Once the modification is approved and available, we may consider additional rulemaking. We have not changed the AD in this regard.

Conclusion

We have carefully reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD as proposed.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules onaviation 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 AD will not have federalism implications under Executive Order 13132. This AD will 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 this AD:

(1) Is not a "significant regulatory action'' under Executive Order 12866;

(2) Is not a "significant rule'' under 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 AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.
