14 CFR Part 39

[Docket No. FAA-2016-9393; Directorate Identifier 2014-NM-199-AD; 
Amendment 39-18935; AD 2017-13-05]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2013-13-16 for 
all Airbus Model A330-200, A330-200 Freighter, A330-300 series 
airplanes; and all Airbus Model A340-200, -300, -500, and -600 series 
airplanes. AD 2013-13-16 required repetitive inspections for 
discrepancies of the ball-screw assembly of the trimmable horizontal 
stabilizer actuator (THSA), repetitive greasing of the THSA ball-nut, 
and replacement of the THSA if necessary; and modification or 
replacement (as applicable) of the ball-nut assembly, which ends 
certain repetitive inspections. This new AD requires an inspection, 
corrective actions if necessary, lubrication of the ball-nut, 
modification of the THSA, and removal of certain airplanes from the 
applicability. This AD was prompted by a determination that a 
modification that automatically detects failure of the ball-screw 
assembly is necessary. We are issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective August 28, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 28, 
2017.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2013-13-16, Amendment 39-17504 (78 FR 47537, 
August 6, 2013) (``AD 2013-13-16''). AD 2013-13-16 applied to all 
Airbus Model A330-200, A330-200 Freighter, A330-300 series airplanes, 
and all Airbus Model A340-200, -300, -500, and -600 series airplanes. 
The NPRM published in the Federal Register on December 19, 2016 (81 FR 
91882) (``the NPRM'').
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0219, dated September 29, 2014 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition on all Airbus Model A330 
and Model A340 series airplanes. The MCAI states:

    Several cases of transfer tube disconnection from the ball-nut 
of the trimmable horizontal stabilizer actuator (THSA) part number 
(P/N) 47172 and 47147-400 were detected on the ground during 
greasing and maintenance. Investigation results showed that this was 
caused by water ingress into the ball-nut, resulting in the jamming 
of the ball transfer circuit when the water froze. If the three 
(independent) ball circuits fail, then the THSA operates on a fail-
safe nut (which operates without balls), which jams after several 
movements on the ballscrew of the THSA.
    This condition, if not detected and corrected, could damage the 
ball screw and the fail-safe nut, possibly resulting in jamming of 
the THSA and consequent reduced control of the aeroplane.
    To detect at an early stage any distortion or initiation of 
disconnection, [Directorate General for Civil Aviation] DGAC France 
issued AD 2001-356 and AD 2001-357 to require repetitive inspections 
of the transfer tubes and their collars and, depending on findings, 
corrective action(s).
    Prompted by another case of transfer tube disconnection, DGAC 
France issued AD 2001-356R2 and AD 2001-357R2 to require additional 
repetitive greasing and reinforcement of the ball-nut maintenance 
greasing instructions.
    Subsequently, DGAC France issued AD 2002-037 and AD 2002-038 to 
require a modification that was also terminating action for the 
repetitive inspections and greasing tasks required by DGAC France AD 
2001-356R2 and AD 2001-357R2 for the THSA P/N 47172 by application 
of Service Bulletin (SB) A330-27-3085 or SB A340-27-4089 (equivalent 
to Airbus production modification 49590), as applicable, changing 
the THSA P/N from 47172 to 47172-300.
    Later on, DGAC France issued AD 2002-414 (later revised to R3) 
and AD 2002-415 (later revised to R2), which superseded the DGAC 
France AD 2001-356R2, AD 2001-357R2, AD 2002-037, and AD 2002-038, 
requiring:

--Repetitive inspections of all THSA P/N in service,
--repetitive lubrication of some THSA P/N, and
--replacement of THSA P/N 47172, 47147-400 and 47147-2XX/-3XX.

    In addition, the electrical flight control computers monitor the 
operation of the THSA and the jamming of this actuator could be 
detected and indicated by messages on the maintenance system and on 
the [electronic centralized aircraft monitor] ECAM. For that

[[Page 34252]]

reason, DGAC France AD 2002-414 and AD 2002-415 also required 
inspection of the THSA after display of such message(s).
    After those [DGAC France] ADs were issued, Airbus introduced 4 
new THSA, P/N 47172-500, P/N 47172-510, P/N 47172-520 and P/N 47172-
530.
    As these new THSA also needed to be inspected/lubricated, EASA 
issued AD 2010-0192 and [EASA] AD 2010-0193 [which correspond to FAA 
AD 2013-13-16], which retained the requirements of DGAC France AD F-
2002-414R3 and AD F-2002-415R2 respectively, which were superseded, 
to add required repetitive inspections and lubrications of the new 
THSA P/N.
    Since those [EASA] ADs were issued, all requirements of EASA AD 
2010-0192 and [EASA] AD 2010-0193 were transferred into Airbus 
Airworthiness Limitations Section (ALS) Part 4, except the 
requirement of paragraph (2.3) of those [EASA] ADs. At this time, 
compliance with ALS Part 4 tasks is required by EASA AD 2013-0268 
(A330 aeroplanes) and [EASA] AD 2013-0269 (A340 aeroplanes), 
respectively [which correspond to FAA AD 2015-16-02, Amendment 39-
18227 (80 FR 48019, August 11, 2015) (A330 airplanes); and AD 2014-
23-17, Amendment 39-18033 (79 FR 71304, December 2, 2014) (A340 
airplanes); respectively.]
    In addition, Airbus developed a Checkable Shear Pin (CSP) for 
the THSA and an associated additional electrical harness, which 
consists of installation of two Electrical Detection Devices (EDD) 
on the lower attachment secondary load path, which gives an 
indication to the Flight Control Primary Computers of secondary load 
path engagement.
    After embodiment of these modifications on an aeroplane, the 
repetitive inspections of the ballscrew assembly for integrity of 
the primary and secondary load paths is no longer required, because 
the failure is detected automatically by this new device.
    For the reasons described above, this [EASA] AD retains only the 
requirement of paragraph (2.3) of EASA AD 2010-0192 and 2010-0193 
[actions following ECAM fault messages], which are superseded, and 
requires the installation of CSP and associated additional 
electrical harness on the THSA of the aeroplane. This [EASA] AD also 
requires, for A340-500/-600 aeroplanes that are post-SB A340-92-5008 
(at Revision 06 or earlier), accomplishment of A340 ALS Part 3 task 
274000-B0002-1-C, providing a grace period of 3 months for 
aeroplanes that have exceeded the applicable threshold or interval.

    The unsafe condition is the degraded operation of the THSA, which 
could result in reduced control of the airplane.
    Model A330-223F and A330-243F airplanes have been removed from the 
applicability of this AD to correspond with the MCAI.
    Required actions include a detailed inspection and corrective 
actions if an ECAM fault message is displayed, repetitive lubrication 
of the THSA ball-nut, and a modification of the THSA by installing a 
CSP and associated electrical harness.
    Required actions also include certain ``Additional Work'' that is 
described in the following service information.
     ``Additional Work'' in Airbus Service Bulletin A330-27-
3143, Revision 01, dated July 10, 2012, is described as removing the 
closing plug from the electrical harness 4515VB and connecting the 
electrical harness 4515VB to the THSA.
     ``Additional Work'' in Airbus Service Bulletin A330-92-
3046, Revision 07, dated January 13, 2017; and in Airbus Service 
Bulletin A340-92-4056, Revision 04, dated December 5, 2013; is 
described as replacement of a certain harness item, installation of 
placards and cable support, modification of a certain bracket, and 
installation of a certain spacer.
     ``Additional Work'' in Airbus Service Bulletin A340-92-
5008, Revision 07, dated February 8, 2013, is described as replacing a 
certain wiring harness, replacing a certain THSA harness, installing 
additional placards, and modifying a certain wire harness installation 
order.

9393.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

New Service Information

    Since we issued the NPRM, we have reviewed Airbus Service Bulletin 
A330-92-3046, Revision 07, dated January 13, 2017 (we referred to 
Airbus Service Bulletin A330-92-3046, Revision 06, dated November 15, 
2013, as one of the appropriate sources of service information for 
installing an electrical harness). Airbus Service Bulletin A330-92-
3046, Revision 07, dated January 13, 2017, includes minor updates to 
the procedures and illustrations. We have revised figure 2 to 
paragraphs (h) and (i) of this AD and figure 3 to paragraph (j) of this 
AD to refer to Airbus Service Bulletin A330-92-3046, Revision 07, dated 
January 13, 2017. We have also added paragraph (r)(2) to this AD to 
give credit for actions done in accordance with Airbus Service Bulletin 
A330-92-3046, Revision 06, dated November 15, 2013.

Costs of Compliance Change

    The costs of compliance information in the NPRM included a parts 
cost of $14,198. We have revised the costs of compliance information in 
this AD based on receiving updated cost information from the 
manufacturer to include a parts cost of $17,481.

Conclusion

    We reviewed the relevant data, and determined that air safety and 
the public interest require adopting this AD with the changes 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 correcting 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 AD.

    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.

Costs of Compliance

    We estimate that this AD affects 33 airplanes of U.S. registry.
    The actions required by AD 2013-13-16, and retained in this AD take 
about 1 work-hour per product, at an average labor rate of $85 per 
work-hour. Based on these figures, the estimated cost of the actions 
that are required by AD 2013-13-16 is $85 per product.
    We also estimate that it takes about 67 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts would cost about $17,481 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $764,808, or $23,176 per product.

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.
