SUMMARY: We are adopting a new airworthiness directive (AD) for all
Airbus Model A330-200 Freighter, A330-200, A330-300, A340-200, A340-
300, A340-500, and A340-600 series airplanes. This AD was prompted by
the results of endurance qualification tests on the trimmable
horizontal stabilizer actuator (THSA), which revealed a partial loss of
the no-back brake (NBB) efficiency in specific load conditions. This AD
requires inspecting certain THSAs to determine the number of total
flight cycles the THSA has accumulated, and replacing the THSA if
necessary. We are issuing this AD to detect and correct premature wear
of the carbon friction disks on the NBB of the THSA. Such a condition
could lead to reduced braking efficiency in certain load conditions
and, in conjunction with the inability of the power gear train to keep
the ball screw in its last commanded position, could result in
uncommanded movements of the trimmable horizontal stabilizer (THS) and
loss of control of the airplane.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of proposed rulemaking (SNPRM) to
amend 14 CFR part 39 by adding an AD that would apply to all Airbus
Model A330-200 Freighter, A330-200, A330-300, A340-200, A340-300, A340-
500, and A340-600 series airplanes. The SNPRM published in the Federal
Register on December 23, 2015 (80 FR 79738) (``the SNPRM''). We
preceded the SNPRM with a notice of proposed rulemaking (NPRM) that
published in the Federal Register on February 3, 2014 (79 FR 6104)
(``the NPRM''). The NPRM proposed to require inspecting certain THSAs
to determine the number of total flight cycles the THSA has
accumulated, and replacing the THSA if necessary. The NPRM was prompted
by the results of endurance qualification tests on the THSA, which
revealed a partial loss of the NBB efficiency in specific load
conditions. The SNPRM proposed to revise the NPRM by adding airplanes
to the proposed applicability, reducing the proposed compliance times
for replacing affected TSHAs, and revising the definition of a
serviceable THSA. We are issuing this AD to detect and correct
premature wear of the carbon friction disks on the NBB of the THSA.
Such a condition could lead to reduced braking efficiency in certain
load conditions and, in conjunction with the inability of the power
gear train to keep the ball screw in its last commanded position, could
result in uncommanded movements of the THS and loss of 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
Airworthiness Directive 2014-0257R1, dated May 29, 2015 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition on all Airbus Model A330-
200, A330-200 Freighter, A330-300, A340-200, and A340-300 series
airplanes; and Model A340-500 and A340-600 series airplanes. The MCAI
states:
During endurance qualification tests on Trimmable Horizontal
Stabilizer Actuator (THSA) of another Airbus aeroplane type, a
partial loss of the no-back brake (NBB) efficiency was experienced.
Due to THSA design similarity on the A330/A340 fleet, a similar
partial loss of the NBB efficiency was identified on THSA Part
Number (P/N) 47147 as installed on A330-300 and A340-200/-300
aeroplanes, on THSA P/N 47172 as installed on A330-200/-300 and
A340-200/-300 aeroplanes, and on THSA P/N 47175 as installed on
A340-500/600 aeroplanes.
Investigation results concluded that this partial loss of
braking efficiency in some specific aerodynamic load conditions was
due to polishing and auto-contamination of the NBB carbon friction
disks.
This condition, if not detected and corrected and in conjunction
with the power gear train not able to keep the ball screw in its
last commanded position, could lead to uncommanded movements of the
THS, possibly resulting in loss of control of the aeroplane.
To address this potential unsafe condition, EASA issued AD 2013-
0144 [<a href="http://ad.easa.europa.eu/blob/easa_ad_2013_0144.zip/AD_2013-0144R1_2">http://ad.easa.europa.eu/blob/easa_ad_2013_0144.zip/AD_2013-0144R1_2</a>] to require replacement of each THSA that has exceeded
16,000 flight cycles (FC) in service, to be sent in shop for NBB
carbon disk replacement.
Since that AD was issued, a need for clarification has been
demonstrated, regarding the identification of the THSA `affected' by
this requirement.
For this reason, EASA AD 2013-0144 [<a href="http://ad.easa.europa.eu/blob/easa_ad_2013_0144.zip/AD_2013-0144R1_2">http://ad.easa.europa.eu/blob/easa_ad_2013_0144.zip/AD_2013-0144R1_2</a>] was revised, confirming
that this AD only affected those THSA identified by Part Number (P/
N) in Airbus Alert Operator Transmission (AOT) A27L005-13. In
addition, a note was added to make clear that the life limits as
specified in the current revision of ALS Part 4 are still relevant
for the affected THSA, as applicable to aeroplane model and THSA P/
N.
Since EASA AD 2013-0144R1 [<a href="http://ad.easa.europa.eu/ad/2013-0144R1">http://ad.easa.europa.eu/ad/2013-0144R1</a>] was issued, further assessment of the ageing/endurance issue
has resulted in the conclusion that there is a need to replace the
NBB installed on the THSA.
Consequently, EASA issued AD 2014-0257 [<a href="http://ad.easa.europa.eu/blob/EASA_AD_2014_0257_R1.pdf/AD_2014-0257R1_1">http://ad.easa.europa.eu/blob/EASA_AD_2014_0257_R1.pdf/AD_2014-0257R1_1</a>]
which retained the requirements of EASA AD 2013-0144R1, which was
superseded, and required removal from service of affected THSA. THSA
should be sent in shop for NBB carbon disk replacement. This [EASA]
AD affected additional THSA P/Ns when compared to EASA AD 2013-
0144R1 and Airbus AOT A27L005-13.
Since that [EASA] AD was issued, it was determined that it is
necessary to consider that the THSA removal for NBB disks
replacement could also be calculated since last NBB disk replacement
which was done in-shop.
This AD also adds Model A340-541 and A340-642 airplanes to the
applicability. You may examine the MCAI in the AD docket on the
Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating
Docket No. FAA-2014-0006.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the SNPRM or on the determination
of the cost to the public.
Conclusion
We reviewed the relevant data 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:
<bullet> Are consistent with the intent that was proposed in the
SNPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the SNPRM.
Related Service Information Under 1 CFR Part 51
Airbus has issued the following service information, all dated July
15, 2014.
<bullet> Service Bulletin A330-27-3199 (for Model A330 series
airplanes);
<bullet> Service Bulletin A340-27-4190 (for Model A340-200 and -300
series airplanes); and
<bullet> Service Bulletin A340-27-5062 (for Model A340-500 and -600
series airplanes).
The service information describes procedures for inspecting the

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.
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.

standards district office/certificate holding district office. The
AMOC approval letter must specifically reference this AD.
(2) Contacting the Manufacturer: For any requirement in this AD
to obtain corrective actions from a manufacturer, the action must be
accomplished using a method approved by the Manager, International
Branch, ANM-116, Transport Airplane Directorate, FAA; or the
European Aviation Safety Agency (EASA); or Airbus's EASA Design
Organization Approval (DOA). If approved by the DOA, the approval
must include the DOA-authorized signature.
(3) Required for Compliance (RC): If any service information
contains procedures or tests that are identified as RC, those
procedures and tests must be done to comply with this AD; any
procedures or tests that are not identified as RC are recommended.
Those procedures and tests that are not identified as RC may be
deviated from using accepted methods in accordance with the
operator's maintenance or inspection program without obtaining
approval of an AMOC, provided the procedures and tests identified as
RC can
