Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued Airworthiness Directive 2012–0198, dated September 26, 2012 (which superseded EASA AD 2012–0133, dated July 18, 2012) (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: * * * The FAA published Special Federal Aviation Regulation (SFAR) 88, and the Joint Aviation Authorities (JAA) published Interim Policy INT/POL/25/12. In the framework of these requirements, EASA have determined that the electrical power supply circuits of certain fuel pumps, installed on A320 family aeroplanes, for which the canisters become uncovered during normal operation, could, under certain conditions, create an ignition source in the tank vapour space. This condition, if not corrected, could result in a fuel tank explosion and consequent loss of the aeroplane. To address this potential unsafe condition, Airbus developed a modification which includes installing Ground Fault Interrupters (GFI) into the centre tank fuel pump control circuit, providing additional system protection by electrically isolating the pump in case of a ground fault condition downstream of the GFI. Consequently, EASA issued AD 2012–0133 to require modification of the centre tank fuel E:\FR\FM\23OCP1.SGM 23OCP1 64766 Federal Register / Vol. 77, No. 205 / Tuesday, October 23, 2012 / Proposed Rules pump control circuit by installing GFI and thereafter, in case a GFI failed an operational test, replacement of the faulty GFI, or deactivation of the associated fuel pump in accordance with the provisions of the applicable Master Minimum Equipment List (MMEL). Since that [EASA] AD was issued, it was noted that, inadvertently, the Applicability of the Final AD was incorrect (the preceding PAD [proposed AD] 12–051 was correct) by excluding aeroplanes on which Airbus modification 150736 has been embodied in production. As a result, the required actions when a GFI fails an operational test did not apply to those aeroplanes. For the reasons described above, this [EASA] AD retains the requirements [modification of the centre tank fuel pump control circuit by installing GFI] of EASA AD 2012–0133, which is superseded, and expands the Applicability to aeroplanes on which Airbus modification 150736 has been embodied in production. The required actions also include either replacement of the GFI or deactivation of the associated fuel pump following failure of any post-modification operational test of the GFI. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Service Bulletin A320–28–1188, dated March 23, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. mstockstill on DSK4VPTVN1PROD with PROPOSALS FAA’s Determination and Requirements of This Proposed 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 proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 755 products of U.S. registry. We also estimate that it would take about 11 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $3,360 per product, depending on configuration. Where the service information lists required parts costs that are covered under warranty, we have assumed that VerDate Mar<15>2010 16:28 Oct 22, 2012 Jkt 229001 there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $3,242,725, or $4,295 per product. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: Authority for This Rulemaking 1. The authority citation for part 39 continues to read as follows: 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 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 this 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); 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 proposed AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION: FOR FURTHER INFORMATION CONTACT: Discussion We proposed to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) with a notice of proposed rulemaking (NPRM) for a new AD for certain Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Galaxy and Gulfstream 200 airplanes. That NPRM was published in the Federal Register on May 31, 2012 (77 FR 32069). The NPRM would have required determining the lengths of the wear indicating pins of all brake assemblies, shortening the pin if the wear indicating pin is too long, inspecting for normal brake wear, and replacing brakes with new brakes if necessary. The NPRM resulted from reports of degraded brake performance during landing due to improperly-sized wear indicating pins. The proposed actions were intended to detect and correct improperly-sized wear indicating pins, which, if not corrected, could result in worn-out brake pads and subsequent loss of braking power, which could result in runway overruns. Actions Since NPRM (77 FR 32069, May 31, 2012) Was Issued Since we issued the NPRM (77 FR 32069, May 31, 2012), FAA has received new data that indicates the unsafe condition no longer exists. Review of the Gulfstream Aerospace LP Model Galaxy and Gulfstream 200 airplane service history shows that the worldwide fleet is in compliance with the actions specified in Gulfstream Service Bulletin 200–32–389, Revision 1, dated October 27, 2011. Therefore, the unsafe condition no longer exists. FAA’s Conclusions Upon further consideration, we have determined that the actions specified in Gulfstream Service Bulletin 200–32– 389, Revision 1, dated October 27, 2011, and the Gulfstream Aerospace LP Model Galaxy and Gulfstream 200 airplane service history adequately addressed the identified unsafe condition. Therefore, it is not necessary to issue a final rule. Accordingly, the NPRM (77 FR 32069, May 31, 2012) is withdrawn.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of Proposed Rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A318, A319, and A320 series airplanes. This proposed AD 
was prompted by fuel system reviews conducted by the manufacturer, 
which revealed that certain fuel pumps under certain conditions can 
create an ignition source in the fuel tank. This proposed AD would 
require modification of the center tank fuel pump control circuit by 
installation of ground fault interrupters (GFIs). This proposed AD 
would also require either replacement of the GFI or deactivation of the 
associated fuel pump following failure of any post-modification 
operational test of the GFI. We are proposing this AD to prevent the 
potential of ignition sources inside fuel tanks, which, in combination 
with flammable fuel vapors, could result in fuel tank explosions and 
consequent loss of the airplane.

DATES: We must receive comments on this proposed AD by December 7, 
2012.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued 
Airworthiness Directive 2012-0198, dated September 26, 2012 (which 
superseded EASA AD 2012-0133, dated July 18, 2012) (referred to after 
this as ``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:
    * * * The FAA published Special Federal Aviation Regulation 
(SFAR) 88, and the Joint Aviation Authorities (JAA) published 
Interim Policy INT/POL/25/12.
    In the framework of these requirements, EASA have determined 
that the electrical power supply circuits of certain fuel pumps, 
installed on A320 family aeroplanes, for which the canisters become 
uncovered during normal operation, could, under certain conditions, 
create an ignition source in the tank vapour space.
    This condition, if not corrected, could result in a fuel tank 
explosion and consequent loss of the aeroplane.
    To address this potential unsafe condition, Airbus developed a 
modification which includes installing Ground Fault Interrupters 
(GFI) into the centre tank fuel pump control circuit, providing 
additional system protection by electrically isolating the pump in 
case of a ground fault condition downstream of the GFI.
    Consequently, EASA issued AD 2012-0133 to require modification 
of the centre tank fuel

[[Page 64766]]

pump control circuit by installing GFI and thereafter, in case a GFI 
failed an operational test, replacement of the faulty GFI, or 
deactivation of the associated fuel pump in accordance with the 
provisions of the applicable Master Minimum Equipment List (MMEL).
    Since that [EASA] AD was issued, it was noted that, 
inadvertently, the Applicability of the Final AD was incorrect (the 
preceding PAD [proposed AD] 12-051 was correct) by excluding 
aeroplanes on which Airbus modification 150736 has been embodied in 
production. As a result, the required actions when a GFI fails an 
operational test did not apply to those aeroplanes.
    For the reasons described above, this [EASA] AD retains the 
requirements [modification of the centre tank fuel pump control 
circuit by installing GFI] of EASA AD 2012-0133, which is 
superseded, and expands the Applicability to aeroplanes on which 
Airbus modification 150736 has been embodied in production.

The required actions also include either replacement of the GFI or 
deactivation of the associated fuel pump following failure of any post-
modification operational test of the GFI. You may obtain further 
information by examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Service Bulletin A320-28-1188, dated March 23, 
2012. 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 Proposed 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 proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 755 products of U.S. registry. We also estimate that 
it would take about 11 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost about $3,360 per product, 
depending on configuration. Where the service information lists 
required parts costs that are covered under warranty, we have assumed 
that there will be no charge for these parts. As we do not control 
warranty coverage for affected parties, some parties may incur costs 
higher than estimated here. Based on these figures, we estimate the 
cost of the proposed AD on U.S. operators to be $3,242,725, or $4,295 
per product.

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 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 this 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);
    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 proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

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.


Sec.  39.13  [Amended]

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

Airbus: Docket No. FAA-2012-1105; Directorate Identifier 2012-NM-
137-AD.

(a) Comments Due Date

    We must receive comments by December 7, 2012.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A318-111, -112, -121, and -122 
airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -
133 airplanes; and Model A320-111, -211, -212, -214, -231, -232, and 
-233 airplanes; certificated in any category; all manufacturer 
serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 28, Fuel.

(e) Reason

    This AD was prompted by fuel system reviews conducted by the 
manufacturer, which revealed that certain fuel pumps under certain 
conditions can create an ignition source in the fuel tank. We are 
issuing this AD to prevent the potential of ignition sources inside 
fuel tanks, which, in combination with flammable fuel vapors, could 
result in fuel tank explosions and consequent loss of the airplane.

(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) Modification

    Except as provided by paragraph (h) of this AD: Within 48 months 
after the effective date of this AD, modify the center tank fuel 
pump control circuit by installing ground fault interrupters (GFIs), 
in accordance with the Accomplishment Instructions of Airbus Service 
Bulletin A320-28-1188, dated March 23, 2012.

(h) Airplanes Excluded From Modification Requirement

    For airplanes on which Airbus modification 150736 has been 
embodied in production, and on which no GFI has been removed since 
first flight, the modification specified in paragraph (g) of this AD 
is not required.

[[Page 64767]]

(i) Corrective Action for Failed Post-modification Operational Test

    After accomplishment of the modification specified in paragraph 
(g) or (h) of this AD, each time a GFI fails an operational test, 
before further flight, replace the GFI or deactivate the associated 
fuel pump, in accordance with a method approved by the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA.

    Note 1 to paragraph (i) of this AD:  Guidance on the operational 
test specified in paragraph (i) of this AD can be found in Task 
28.18.00/01, Operational Check of Centre Tank Fuel Pump GFI, of the 
Airbus A318/A319/A320/A321 Maintenance Review Board Report or Task 
281800-710-801, Operational Check of Centre Tank Fuel Pump GFI, of 
the Airbus A318/A319/A320 Aircraft Maintenance Manual.


    Note 2 to paragraph (i) of this AD:  Guidance on the fuel pump 
deactivation specified in paragraph (h) of this AD can be found in 
Item 28-21-02, Center Tank Systems, of the FAA Master Minimum 
Equipment List for Airbus A318/A319/A320/A321.
