SUPPLEMENTARY INFORMATION:
Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2017-0224, dated November 10, 2017 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all Airbus Model
A330-200, A330-200 Freighter, and A330-300 series airplanes; and Airbus
Model A340-200, A340-300, A340-500, and A340-600 series airplanes. The
MCAI states:
An occurrence was reported of a fuel pump showing cavitation
erosion which breached the fuel pump housing through the inlet webs
and exposed the fuel pump power supply wires. Inspections
accomplished on fuel pumps removed from other aeroplanes identified
signs of erosion in varying degrees. However, no other instance of
break-through due to cavitation erosion was found. A list of
potentially affected fuel pump Part Numbers (P/N) was established.
This condition, if not detected and corrected, could result, in
case the pump is running dry, in an ignition source in the fuel
tank, which may result in a fuel tank explosion and consequent loss
of the aeroplane.
To address this potential unsafe condition, Airbus issued Alert
Operators Transmission (AOT) A28L006-17 to provide instructions to
inspect some fuel pumps when installed at specific positions, and to
update the applicable Master Minimum Equipment List (MMEL).
For the reasons described above, this [EASA] AD requires
repetitive inspections of these fuel pumps and, depending on
findings, replacement of damaged fuel pumps with serviceable parts.
This [EASA] AD also requires an update of the applicable MMEL, and
the reporting of inspection results to Airbus.
This [EASA] AD is considered to be an interim measure and
further [EASA] AD action may follow.
Although the MCAI requires updating the ``master minimum equipment list
(MMEL),'' this AD requires revising the ``minimum equipment list
(MEL).'' The MMEL is a master list of the minimum equipment that the
airplane can operate with under given circumstances. A MEL is derived
from the MMEL and is tailored for individual operators. You may examine
the MCAI on the internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for
and locating Docket No. FAA-2017-1104.
Related Service Information Under 1 CFR Part 51
Airbus has issued Alert Operators Transmission A28L006-17, Rev. 00,
dated November 3, 2017. The service information describes procedures
for inspection of certain fuel pumps for cavitation erosion, and
corrective actions. The service information also describes dispatch
restrictions that affect the MEL. 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.
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 these
same type designs.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because the
unsafe condition could result in an ignition source in the fuel tank,
which could result in a fuel tank explosion. Therefore, we determined
that notice and opportunity for public comment before issuing this AD
are impracticable and that good cause exists for making this amendment
effective in fewer 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
[[Page 58720]]
data, views, or arguments about this AD. Send your comments to an
address listed under the ADDRESSES section. Include ``Docket No. FAA-
2017-1104; Product Identifier 2017-NM-153-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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>, 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
We estimate that this AD affects 107 airplanes of U.S. registry. We
estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators

We estimate the following costs to do any necessary replacements
that would be required based on the results of the inspection. We have
no way of determining the number of aircraft that might need these
replacements:

Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information
Collection Clearance Officer, AES-200.
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.

Administrator, the FAA amends 14 CFR part 39 as follows:

whichever occurs later, inspect all affected fuel pumps for
cavitation erosion, in accordance with the instruction of Airbus AOT
A28L006-17, Rev. 00, dated November 3, 2017. Repeat the inspection
