AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2014-13-17, 
which applied to 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

[[Page 43672]]

called Model A300-600 series airplanes); and Airbus Model A310 series 
airplanes. AD 2014-13-17 required repetitive functional tests of the 
circuit breakers for the fuel pump power supply, and replacement of 
certain circuit breakers. This new AD requires installation of fuel 
pumps having a new standard, which terminates the repetitive functional 
tests. This AD was prompted by our determination that installation of a 
newly developed fuel pump standard will better address the unsafe 
condition. We are issuing this AD to address the unsafe condition on 
these products.

DATES: This AD is effective October 24, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 24, 
2017.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2014-13-17, Amendment 39-17893 (79 FR 41098, 
July 15, 2014) (``AD 2014-13-17''). AD 2014-13-17 applied to all Airbus 
Model A300 series airplanes; Airbus Model A300-600 series airplanes; 
and Airbus Model A310 series airplanes. The NPRM published in the 
Federal Register on May 16, 2017 (82 FR 22445). The NPRM was prompted 
by reports of failures of the right inner tank fuel pump. The NPRM 
proposed to require installation of fuel pumps having the new standard. 
We are issuing this AD to prevent a fuel pump from overheating, which 
could result in a fuel tank explosion and consequent loss of the 
airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0080, dated April 21, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model A300 
series airplanes; Airbus Model A300-600 series airplanes; and Airbus 
Model A310 series airplanes. The MCAI states:

    Two successive failures have been reported of a Right Hand #1 
inner tank fuel pump, Part Number (P/N) 2052Cxx series (where ``xx'' 
represents any numerical combination). These occurrences were solved 
by replacement of the pump, associated circuit breaker (CB) and the 
alternating current (AC) bus load relay.
    Investigations determined that, in case of loss of one phase on 
the pump supply and the associated CB failing to trip, the fuel pump 
thermal fuses may not operate as quickly as expected.
    This condition, if not detected and corrected, could lead to an 
overheat condition of the fuel pump in excess of 200 [deg]C, 
possibly resulting in a fuel tank explosion and loss of the 
aeroplane.
    To address this potential unsafe condition, Airbus issued Alert 
Operator Transmission (AOT) A28W002-13 providing instructions for 
functional tests of CBs.
    As a temporary measure, EASA issued AD 2013-0163 [which 
corresponds to FAA AD 2014-13-17] to require repetitive functional 
tests of the affected fuel pump power supply CBs, and, depending on 
findings, replacement.
    Since that [EASA] AD was issued, a new standard of fuel pump was 
developed, which improves the thermal protection, thereby preventing 
the potential unsafe condition and cancelling the need for 
repetitive functional tests of the affected CBs, as required by EASA 
AD 2013-0163. Airbus issued Service Bulletin (SB) A300-28-0093, SB 
A300-28-6111, SB A300-28-9025 and SB A310-28-2176 to provide 
instructions for this upgrade of the fuel pump for all positions on 
the aeroplane.
    For the reasons described above, this [EASA] AD retains the 
requirements EASA AD 2013-0163, which is superseded, and requires 
installation of the new standard fuel pump, which constitutes 
terminating action for the repetitive functional tests.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0339.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Support for the NPRM

    FedEx Express stated that it concurs with the proposed corrective 
actions.

Suggestion To Organize Files by Airplane Serial Number

    One commenter, Anani Fleur, suggested that the FAA set up files for 
every airplane by serial number. The commenter stated that the file 
system should be computerized and that FAA employees could do this.
    We acknowledge the commenter's suggestion. Since it does not 
address the unsafe condition identified in this AD, we have not changed 
this AD regarding this issue.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
this AD as proposed except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information, which 
describes procedures for installing new standard fuel pumps with 
improved thermal protection. These documents are distinct since they 
apply to different airplane models in different configurations.

[[Page 43673]]

     Service Bulletin A300-28-0093, dated December 15, 2015.
     Service Bulletin A300-28-6111, Revision 01, dated February 
29, 2016.
     Service Bulletin A310-28-2176, dated December 15, 2015.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 128 airplanes of U.S. registry.
    The actions required by AD 2014-13-17 and retained in this AD take 
about 1 work-hour per product, at an average labor rate of $85 per 
work-hour. Based on these figures, the estimated cost of the actions 
that are required by AD 2014-13-17 is $85 per product, per inspection 
cycle.
    We also estimate that it will take up to 21 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts cost per product is not 
available. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be up to $228,480, or up to $1,785 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.
    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 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.
