DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2013–0973; Directorate Identifier 2013–NM–139–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Examining the AD Docket Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Airbus Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes); and A310 series airplanes. This proposed AD was prompted by reports of failures of the right inner tank fuel pump. This proposed AD would require repetitive functional tests of the circuit breakers for the fuel pump power supply, and replacement of any circuit breaker that fails any functional test or is found to be stuck closed. We are proposing this AD to detect and correct failure of the thermal fuses in the fuel pumps, which could result in a fuel pump overheating, leading to a fuel tank explosion.

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 2013–0163, dated July 24, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Two successive failures have been reported of a Right Hand # 1 inner tank fuel pump, Part Number 2052Cxx series (with placeholder ‘‘xx’’ indicating numerals). The fix consisted in the replacement of the pump, the associated circuit breaker and the AC [alternating current] bus load relay. Investigations determined that, in case of loss of one phase on the pump supply and the associated circuit breaker failing to trip, the fuel pump thermal fuses may not operate as quickly as expected. This condition, if not detected and corrected, would result in an overheat condition of the fuel pump in excess of 200 °C and could lead to a fuel tank explosion. To address this potential unsafe condition, Airbus issued Alert Operator Transmission (AOT) A28W002–13 providing instructions for a functional test of circuit breakers and corrective action. For the reasons described above, as a temporary measure until further notice, this [EASA] AD mandates functional tests of the affected fuel pump power supply circuit breakers, and, depending on findings, replacement of circuit breakers. This [EASA] AD will be followed by further [EASA] AD action. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating it in Docket No. FAA– 2013–0973. Relevant Service Information Airbus has issued Alert Operators Transmission A28W002–13, dated July 23, 2013. 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 E:\FR\FM\22NOP1.SGM 22NOP1 70004 Federal Register / Vol. 78, No. 226 / Friday, November 22, 2013 / Proposed Rules 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 We estimate that this proposed AD affects 156 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Repetitive functional tests. Labor cost Parts cost Cost per product 1 work-hour × $85 per hour = $85 per test ........ $0 $85 per test .................. List of Subjects in 14 CFR Part 39 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. ehiers on DSK2VPTVN1PROD with PROPOSALS-1 We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. The Proposed Amendment Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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. VerDate Mar<15>2010 14:00 Nov 21, 2013 Jkt 232001 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.

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 A300 series airplanes; Airbus Model A300 B4-600, B4-600R, 
and F4-600R series airplanes, and Model A300 C4-605R Variant F 
airplanes (collectively called Model A300-600 series airplanes); and 
A310 series airplanes. This proposed AD was prompted by reports of 
failures of the right inner tank fuel pump. This proposed AD would 
require repetitive functional tests of the circuit breakers for the 
fuel pump power supply, and replacement of any circuit breaker that 
fails any functional test or is found to be stuck closed. We are 
proposing this AD to detect and correct failure of the thermal fuses in 
the fuel pumps, which could result in a fuel pump overheating, leading 
to a fuel tank explosion.

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 2013-0163, dated July 24, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Two successive failures have been reported of a Right Hand 
 1 inner tank fuel pump, Part Number 2052Cxx series (with 
placeholder ``xx'' indicating numerals). The fix consisted in the 
replacement of the pump, the associated circuit breaker and the AC 
[alternating current] bus load relay.
    Investigations determined that, in case of loss of one phase on 
the pump supply and the associated circuit breaker failing to trip, 
the fuel pump thermal fuses may not operate as quickly as expected.
    This condition, if not detected and corrected, would result in 
an overheat condition of the fuel pump in excess of 200 [deg]C and 
could lead to a fuel tank explosion.
    To address this potential unsafe condition, Airbus issued Alert 
Operator Transmission (AOT) A28W002-13 providing instructions for a 
functional test of circuit breakers and corrective action.
    For the reasons described above, as a temporary measure until 
further notice, this [EASA] AD mandates functional tests of the 
affected fuel pump power supply circuit breakers, and, depending on 
findings, replacement of circuit breakers.
    This [EASA] AD will be followed by further [EASA] AD action.

    You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov by searching for and locating it in Docket No. 
FAA-2013-0973.

Relevant Service Information

    Airbus has issued Alert Operators Transmission A28W002-13, dated 
July 23, 2013. 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

[[Page 70004]]

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

    We estimate that this proposed AD affects 156 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

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.

of the thermal fuses in the fuel pumps, which could result in a fuel 
pump overheating, leading to a fuel tank explosion.

(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) Repetitive Functional Tests of Circuit Breakers

    (1) Within 6 months or 500 flight hours after the effective date 
of this AD, whichever occurs first: Do a functional test of the 
circuit breakers for the fuel pump power supply, as identified in 
paragraphs (g)(1)(i), (g)(1)(ii), and (g)(1)(iii) of this AD, as 
applicable, in accordance with Airbus Alert Operators Transmission 
A28W002-13, dated July 23, 2013. Repeat the functional test 
thereafter at intervals not to exceed 6 months or 500 flight hours, 
whichever occurs first.
    (i) For Airbus Model A300 B2-1A, B2-1C, B2K-3C, and B2-203 
airplanes: Inner and outer pump, No. 1 and No. 2 left-hand (LH) side
