Discussion
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2014-0248, dated November 19, 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. The MCAI states:
During a design review of aeroplane configuration incorporating Kidde fire extinguisher bottles and optional galley cooling rack installation, it was identified that the air cooling rack is installed too close to the supply hose of the high rated fire extinguishing bottle in the area of frame (FR)34. Inadequate physical separation between the flexible hose and the air cooling rack could lead to chafing, likely resulting in loss of the Fire Extinguishing System for the Lower Deck Cargo Compartment.
This condition, if not corrected, could lead, in caseof fire, to an uncontrolled fire in the cargo compartment, which could ultimately jeopardise the aeroplane's safe flight.
To address this unsafe condition, Airbus developed an improved flexible hose assembly (Airbus mod 200195, available for in-service aeroplanes through Airbus SB A330-26-3046) and EASA issued AD 2013- 0250 (later revised) to require replacement of Part Number (P/N) P/N A2627045200000 flexible hose assembly of the Fire Extinguisher System at FR34.
Since EASA AD 2013-0250R1 was issued, it was discovered that another flexible hose assembly, P/N A2627045400200, is also affected by this chafing issue.
Prompted by this finding, Airbus issued SB A330-26-3046 Revision 02 to incorporate this additional affected P/N and to provide additional work instructions for aeroplanes which accomplished the SB at a previous revision.
For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2013-0250R1, which is superseded, and requires additional work on aeroplanes that have already been modified in accordance with the instructions of the original issue or Revision 01 of the SB.

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 the same type design.
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-2018-0076; Product Identifier 2013-NM-227-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 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

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, AircraftCertification 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 Findings
We 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.
