SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to 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 NPRM 
published in the Federal Register on August 31, 2018 (83 FR 44514). The 
NPRM was prompted by defects found during production tests of RAT 
units; investigation revealed that the defects were due to certain RAT 
hydraulic pumps having an alternative manufacturing process of the pump 
pistons. The NPRM proposed to require replacing any defective RAT 
hydraulic pump with a serviceable part and re-identifying the RAT 
module part number. We are issuing this AD to address low performance 
of the pump, 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.
    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.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We have considered the comment received. The Air Line 
Pilots Association, International indicated its support for the NPRM.

New Service Information

    We received UTC Aerospace Systems Service Bulletin ERPS06M-29-22, 
Revision 2, dated May 24, 2018. We referred to UTC Aerospace Systems 
Service Bulletins ERPS06M-29-22, dated March 17, 2017; and Revision 1, 
dated June 27, 2017; as the appropriate sources of service information 
for identifying certain affected serial numbers and parts therein. 
Revision 2 of the service information adds Hamilton Sundstrand and 
Parker hydraulic pump part number (P/N) 5917648 (Parker P/N 4207905) 
and alternate Hamilton Sundstrand and Parker hydraulic pump P/N 5916485 
(Parker P/N 4207903) to table 3 and table 6 for clarification.
    We have added UTC Aerospace Systems Service Bulletin ERPS06M-29-22, 
Revision 2, dated May 24, 2018, to the Related Service Information 
under 1 CFR part 51 section of this AD as an appropriate source of 
service information. We have also added Revision 2 of the service 
information to the definitions specified in paragraph (g)(1) of this 
AD.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this final rule with the change described previously and minor 
editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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
