We propose to adopt a new airworthiness directive (AD) for all Airbus Model A350-941 airplanes. This proposed AD was prompted by a report of an overheat failure mode of the hydraulic engine-driven pump, which could cause a fast temperature rise of the hydraulic fluid. This proposed AD would require modifying the hydraulic monitoring and control application (HMCA) software. We are proposing this AD to address the unsafe condition on these products.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
2017-0200, dated October 10, 2017 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for all Airbus Model A350-941 airplanes.
The MCAI states:

In the Airbus A350 design, the hydraulic fluid cooling system is
located in the fuel tanks. Recently, an overheat failure mode of the
hydraulic engine-driven pump (EDP) was found. Such EDP failure may
cause a fast temperature rise of the hydraulic fluid.
This condition, if not detected and corrected, combined with an
inoperative fuel tank inerting system, could lead to an uncontrolled
overheat of the hydraulic fluid, possibly resulting in ignition of
the fuel-air mixture in the affected fuel tank.
To address this potential unsafe condition, Airbus issued a
Major Event Revision (MER) of the A350 Master Minimum Equipment List
(MMEL) that incorporates restrictions to avoid an uncontrolled
overheat of the hydraulic system. Consequently, EASA issued
Emergency AD 2017-0154-E to require implementation of these dispatch
restrictions.
Since EASA Emergency AD 2017-0154-E was issued, following
further investigation, Airbus issued another MER of the A350 MMEL
that expands the number of restricted MMEL items. At the same time,
Airbus revised Flight Operation Transmission (FOT) 999.0068/17, to
inform all operators about the latest MMEL restrictions.
Consequently, EASA issued AD 2017-0180, retaining the requirements
of EASA Emergency AD 2017-0154-E, which was superseded, and
requiring implementation of the new Airbus A350 MMEL MER and,
consequently, restrictions for aeroplane dispatch.
Since EASA AD 2017-0180 was issued, Airbus developed a software
(SW) update of the Hydraulic Monitoring and Control Application
(HMCA) SW S4.2, introduction of which avoids uncontrolled overheat
of the hydraulic system. HMCA SW S4.2 is embodied in production
through Airbus modification (mod) 112090, and introduced in service
through Airbus Service Bulletin (SB) A350-29-P012.
For the reasons described above, this [EASA] AD retains the
requirements of EASA AD 2017-0180, which is superseded, and requires
modification of the aeroplane by installing HMCA SW S4.2.
This [EASA] AD is still considered to be an interim action and
further AD action may follow.

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-2018-
0505.

Related Service Information Under 1 CFR Part 51

Airbus has issued Service Bulletin A350-29-P012, dated October 6,
2017. The service information describes procedures for modifying the
HMCA software by installing HMCA software S4.2 upgrades. 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.

[[Page 26881]]

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

We estimate that this proposed AD affects 7 airplanes of U.S.
registry. We estimate the following costs to comply with this proposed
AD:

Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170........................... $450 $620 $4,340
----------------------------------------------------------------------------------------------------------------

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 proposed 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 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.

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:
