We propose to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-200 Freighter series airplanes, Model A330-200 and -300 series airplanes, and Model A340-200 and -300 series airplanes. This proposed AD was prompted by defects found during production tests of ram air turbine (RAT) units; investigation revealed that the defects were due to certain RAT hydraulic pumps having an alternative manufacturing process of the pump pistons. This proposed AD would require replacing any defective RAT hydraulic pump with a serviceable part and re-identifying the RAT module part number. 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
2018-0062, dated March 20, 2018 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for all Airbus SAS Model A330-200 Freighter
series airplanes, Model A330-200 and -300 series airplanes, and Model
A340-200 and -300 series airplanes. The MCAI states:

Four A330 RAT units were returned to the supplier due to low
discharge pressure. These defects were detected during Airbus
production tests. Subsequent investigations by the RAT manufacturer
UTAS (formerly Hamilton Sundstrand) revealed that some RAT hydraulic
pumps, [part number] P/N 5916430, were involved in an alternative
manufacturing process of the pump pistons. This resulted in form
deviations (rough surface finish and sharp edges), which caused
excessive wear and damage to the bore where the pistons moved.
This condition, if not corrected, could lead to low performance
of the pump, possibly resulting in reduced control of the aeroplane,
particularly if occurring following a total engine flame out, or
during a total loss of normal electrical power generation.
To address this potential unsafe condition, Airbus published
[service bulletin] SB A330-29-3130 and SB A340-29-4098, providing
instructions for identification and replacement of the affected
parts.
For the reasons described above, this [EASA] AD requires
replacement of the affected parts. This [EASA] AD also requires re-
identification of the RAT module.

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-
0764.

Other Related Rulemaking

The FAA issued AD 2016-14-01, Amendment 39-18582 (81 FR 44983, July
12, 2016); corrected (81 FR 51097, August 3, 2016) (``AD 2016-14-01'').
AD 2016-14-01 applies to certain Airbus SAS Model A330-200 Freighter
series airplanes; Model A330-200 and A330-300 series airplanes; Model
A340-200 and A340-300 series airplanes; Model A340-500 series
airplanes; and Model A340-600 series airplanes. AD 2016-14-01 requires
identification of the manufacturer, part number, and serial number of
the RAT, and re-identification and modification of the RAT if
necessary. AD 2016-14-01 was prompted by a report indicating that,
during an operational test of a RAT, the RAT did not deploy in
automatic mode. AD 2016-14-01 was issued to prevent non-deployment of
the RAT, which, following a total engine flame-out, or during a total
loss of normal electrical power generation, could result in reduced
control of the airplane.

Related Service Information Under 1 CFR Part 51

Airbus SAS has issued Service Bulletins A330-29-3130 and A340-29-
4098, both dated May 3, 2017. This service information describes
procedures for replacing any affected RAT hydraulic pump with a
serviceable

part and re-identifying the RAT module part number. These documents are
distinct since they apply to different airplane models.
UTC Aerospace Systems has issued Service Bulletin ERPS06M-29-22,
dated March 17, 2017, and Revision 1, dated June 27, 2017. This service
information identifies affected part and serial numbers for the RAT
hydraulic pump. These documents are distinct since UTC Aerospace
Systems Service Bulletin ERPS06M-29-22, Revision 1, dated June 27,
2017, adds a Parker part number reference to each Hamilton Sundstrand
hydraulic part number.
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

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 the relevant information and determined the unsafe
condition described previously is likely to exist or develop on other
products of the same type design.

Proposed Requirements of This NPRM

This proposed AD would require accomplishing the actions specified
in the service information described previously.

Costs of Compliance

We estimate that this proposed AD affects 103 airplanes of U.S.
registry. We estimate the following costs to comply with this proposed
AD:

Estimated Costs
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 14 work-hours x $85 per hour = Up $0 Up to $1,190.............. Up to $122,570.
to $1,190.
----------------------------------------------------------------------------------------------------------------

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.
