SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2010–0255, PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 7523 dated December 6, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: During the qualification test campaign of the prototype Flow Metering Compact Unit (FMCU) Part Number (P/N) QA07907–03, partial blockage of the water absorbing filter element P/N QA06123 was observed several times. The blockage was created by carbon debris from the cartridge and from the burst disc of the Halon bottle. This water absorbing filter element is part of the FMCU, which are part of the Lower Deck Cargo Compartment (LDCC) fire extinguisher system used in some A340–600 aeroplanes. Blockage of the water absorbing filter element could lead to reduction of the Halon outflow, leading to incapacity to maintain fire extinguishing agent concentration. Combined with fire, this condition could result in an uncontrolled fire in the affected compartment, which would constitute an unsafe condition. To avoid water absorbing filter element blockage, this [EASA] AD requires to convert the fire extinguishing system from the threebottles-system with 4 FMCU into a twobottles-system with 2 Flow Metering Systems (FMS) equipped with upgraded water absorbing filter elements. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Mandatory Service Bulletin A340–26–5020, including Appendix 01, dated June 3, 2010. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. 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 and service information referenced above. 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.

SUPPLEMENTARY INFORMATION: History On October 31, 2011, the FAA published in the Federal Register a notice of proposed rulemaking to amend controlled airspace at Hawthorne, CA (76 FR 67103). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. Class D airspace and Class E airspace designations are published in paragraph 5000 and 6004, respectively, of FAA Order 7400.9V dated August 9, 2011, and effective September 15, 2011, which is incorporated by reference in 14 CFR Part 71.1. The Class D airspace and Class E airspace designations listed in this document will be published subsequently in that Order.

ACTION: Final rule. AGENCY: This action revises Class D and Class E airspace at Jack Northrop Field/Hawthorne Municipal Airport, Hawthorne, CA. Additional controlled airspace is needed to accommodate aircraft departing and arriving under Instrument Flight Rules (IFR) at the airport. Also, the airspace designations are revised to show a new city location. This action is a result of the FAA’s biennial review, along with a study of the Jack Northrop Field/Hawthorne Municipal Airport airspace area that further enhances the safety and management of aircraft operations at the airport.

This action, initiated by FAA’s biennial review of the Jack Northrop Field/ Hawthorne Municipal Airport airspace area, and based on results of a study conducted by the Los Angeles Visual Flight Rules (VFR) Task Force, and the Los Angeles Class B Workgroup, enhances the safety and management of aircraft operations at the airport. This action also revises the airspace designation for Class D and Class E airspace, changing the city location from Los Angeles, CA, to Hawthorne, CA. The FAA has determined this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (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) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 7525 routine matter that will only affect air traffic procedures and air navigation, it is certified this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the U.S. Code. Subtitle 1, Section 106 discusses the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it revises controlled airspace at Jack Northrop Field/Hawthorne Municipal Airport, Hawthorne, CA.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A340-600 series airplanes. This AD requires modifying the 
fire extinguishing system from a three-bottles solution with 4 flow 
metering compact unit into a two-bottles solution with 2 flow metering 
systems equipped with upgraded water absorbing filter elements. This AD 
was prompted by reports of partial blockage of a certain water 
absorbing filter element. We are issuing this AD to prevent partial 
blockage of a certain water absorbing filter element, which could lead 
to reduction of the halon outflow, which leads to incapacity to 
maintain fire extinguishing agent concentration. Combined with fire, 
this condition could result in an uncontrolled fire in the affected 
compartment.

DATES: This AD becomes effective February 28, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of February 28, 
2012.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2010-0255, dated December 6, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:
    During the qualification test campaign of the prototype Flow 
Metering Compact Unit (FMCU) Part Number (P/N) QA07907-03, partial 
blockage of the water absorbing filter element P/N QA06123 was 
observed several times. The blockage was created by carbon debris 
from the cartridge and from the burst disc of the Halon bottle.
    This water absorbing filter element is part of the FMCU, which 
are part of the Lower Deck Cargo Compartment (LDCC) fire 
extinguisher system used in some A340-600 aeroplanes.
    Blockage of the water absorbing filter element could lead to 
reduction of the Halon outflow, leading to incapacity to maintain 
fire extinguishing agent concentration. Combined with fire, this 
condition could result in an uncontrolled fire in the affected 
compartment, which would constitute an unsafe condition.
    To avoid water absorbing filter element blockage, this [EASA] AD 
requires to convert the fire extinguishing system from the three-
bottles-system with 4 FMCU into a two-bottles-system with 2 Flow 
Metering Systems (FMS) equipped with upgraded water absorbing filter 
elements.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A340-26-5020, 
including Appendix 01, dated June 3, 2010. The actions described in 
this service information are intended to correct the unsafe condition 
identified in the MCAI.

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 and service 
information referenced above. 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.
    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future.

[[Page 7524]]

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

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-2012-0112; Directorate 
Identifier 2011-NM-055-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 because of 
those comments.
    We will post all comments we receive, without change, to https://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.

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 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 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

2. The FAA amends Sec.  39.13 by adding the following new AD:

2012-03-10 Airbus: Amendment 39-16952; Docket No. FAA-2012-0112; 
Directorate Identifier 2011-NM-055-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective February 28, 
2012.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A340-642 airplanes, certificated 
in any category, all manufacturer serial numbers on which Airbus 
modification 47090 has been embodied in production; except those on 
which Airbus modification 51065 has been embodied in production.

(d) Subject

    Air Transport Association (ATA) of America Code 26: Fire 
Protection.

(e) Reason

    This AD was prompted by reports of partial blockage of a certain 
water absorbing filter element. We are issuing this AD to prevent 
partial blockage of a certain water absorbing filter element, which 
could lead to reduction of the halon outflow, which leads to 
incapacity to maintain fire extinguishing agent concentration. 
Combined with fire, this condition could result in an uncontrolled 
fire in the affected compartment.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Actions

    Within 18 months after the effective date of this AD, modify the 
fire extinguishing system from a three-bottles solution with 4 flow 
metering compact unit, into a two-bottles solution with 2 flow 
metering systems equipped with upgraded water absorbing filter 
elements, in accordance with the Accomplishment Instructions of 
Airbus Mandatory Service Bulletin A340-26-5020, including Appendix 
01, dated June 3, 2010.
