AD 2018-03-07

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-202, -203, -223, and -243 airplanes; and Model A340- 211, -212, -311, and -313 airplanes. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition on these products, and doing the actions specified in those instructions. This AD was prompted by a report of a hard contact that was found between the constant speed motor/generator feeder line route 6G/6E and the optional cabin temperature control pipe on the upper shell between certain frames. We are issuing this AD to address the unsafe condition on these products.

Final rule; request for comments.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2014-0161, dated July 10, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Airbus Model A330-202, -203, -223, and - 243 airplanes; and Model A340-211, -212, -311, and -313 airplanes. The MCAI states:

A hard contact was found on an A330 aeroplane during production between the Constant Speed Motor/Generator (CSM/G) feeder line route 6G/6E (Functional Item Number 1526VB) and the optional cabin temperature control pipe on the upper shell between Frame (FR)37.4 and FR38 on stringer 5, right hand (RH) side.
This condition, if not corrected, may lead to chafing and, consequently, a short circuit when the emergency generation is activated, resulting in the loss of emergency generation. The loss of normal generation combined with the loss of emergency generation jeopardizes the aeroplane safe flight.
To address this potential unsafe condition, Airbus developed a modification to provide adequate clearance between harness 1526VB and the affected (optional) air-conditioning temperature control pipe. A340-200/-300 aeroplanes equipped with this optional cabin temperature control pipe are also affected by this issue. The modification can be embodied in service through Airbus Service Bulletin (SB) A330-92-3125, or SB A340-92-4097, as applicable.
For the reasons described above, this [EASA] AD requires modification of the CSM/G mounting with installation of new stacking and/or longer bracket, depending on aeroplane configuration.

FAA's Determination and Requirements of This AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of these same type designs.

FAA's Determination of the Effective Date

Since there are currently no domestic operators of this product, we find good cause that notice and opportunity for prior public comment are unnecessary. In addition, for the reason(s) stated above, we find that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2018-0030; Product Identifier 2014-NM-161-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments

[[Page 5305]]

received by the closing date and may amend this AD based on those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

Costs of Compliance

Currently, there are no affected U.S.-registered airplanes. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition, and doing the actions specified in those instructions. Based on the actions specified in the MCAI AD, we are providing the following cost estimates for an affected airplane that is placed on the U.S. Register in the future:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product ---------------------------------------------------------------------------------------------------------------- Modification....................... Up to 17 work-hours x $85 Up to $256........... Up to $1,701.
per hour = $1,445. ----------------------------------------------------------------------------------------------------------------

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.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division.

Regulatory FindingsWe 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 the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
