Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding airworthiness directive (AD) 2005-07-04 for 
all Airbus Model A330-200 and -300 series airplanes, and Model A340-200 
and -300 series airplanes. AD 2005-07-04 required repetitive 
inspections to detect discrepancies of the transfer tubes and the 
collar of the ball nut of the trimmable horizontal stabilizer actuator 
(THSA), and corrective action if necessary; repetitive inspections for 
discrepancies of the ball screw assembly, and corrective action if 
necessary; 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 removes certain inspections, revises certain actions, and 
adds airplanes to the applicability. This AD was prompted by several 
reports of

[[Page 47538]]

disconnection of the transfer tube from the ball nut of the THSA. We 
are issuing this AD to prevent degraded operation of the THSA, which 
could result in reduced controllability of the airplane.

DATES: This AD becomes effective September 10, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 10, 
2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of May 4, 
2005 (70 FR 16104, March 30, 2005).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
The NPRM was published in the Federal Register on October 2, 2012 (77 
FR 60075), and proposed to supersede AD 2005-07-04, Amendment 39-14028 
(70 FR 16104, March 30, 2005). (AD 2005-07-04 superseded AD 2001-11-09, 
Amendment 39-12252 (66 FR 31143, June 11, 2001).) The NPRM proposed to 
correct an unsafe condition for the specified products. The European 
Aviation Safety Agency (EASA), which is the Technical Agent for the 
Member States of the European Community, has issued EASA Airworthiness 
Directive 2010-0192 (corrected), dated October 11, 2010; and EASA 
Airworthiness Directive 2010-0193 (corrected), dated October 11, 2010; 
(referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for the 
specified products. 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.
    This condition is caused by water ingress into the ball-nut 
resulting in the jamming of the ball transfer circuit when the water 
freezes.
    If the three (independent) ball circuits fail, then the THSA 
will operate on a fail-safe nut. This nut (which operates without 
balls) would then jam after several movements on the screw of the 
THSA.
    This degraded operation is not detectable in the cockpit by the 
crew as long as the THSA does not jam and could damage the ball 
screw and the fail-safe nut.
    To detect this unsafe condition, [Direcci[oacute]n General de 
Aviaci[oacute]n Civil] DGAC France AD F-2001-356 [and F-2001-357] 
was issued to require repetitive inspections of the transfer tubes 
and their collars in order to detect at an early stage any 
distortion or initiation of disconnection.
    Further to a new case of transfer tube disconnection, * * * 
[revised DGAC ADs] required an additional repetitive greasing task 
with reinforcement of the ball-nut maintenance greasing 
instructions.
    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 ECAM [electronic centralized aircraft monitor]. In this case a 
mandatory inspection of the THSA is required before the next flight.
    DGAC France AD F-2002-038 [and F-2002-037] required application 
of a final fix (related to inspection and greasing task required by 
DGAC France AD F-2001-356 [and F-2001-357]) for the THSA P/N 47172 
by application of Airbus modification 49590/Service Bulletin (SB) 
A330-27-3085 [or SB A340-27-4089]. It changes the THSA P/N from 
47172 to 47172-300.
    Later on, DGAC France AD F-2002-414R3 replaced the DGAC AD 
France F-2001-356R2 and F-2002-038 [and DGAC France AD F2002-415R2 
superseded DGAC France ADs F-2001-357R2 and F-2002-037] requiring:

--the repetitive [detailed] inspection [for discrepancies] of all 
THSA P/N in service [for integrity of the primary and secondary load 
path and check the Checkable Shear Pins (CSPs)], and
--the lubrication of some THSA P/N, and
--the replacement of THSA P/N 47172, 47147-400 and 47147-2XX/-3XX

[DGAC France AD F-2002-414R3 and F-2002-415R2 correspond to FAA AD 
2005-07-04, Amendment 39-14028 (70 FR 16104, March 30, 2005).]

    Airbus has later introduced 4 new THSA P/N (47172-500, 47172-
510, 47172-520 and 47172-530).
    This [EASA] AD retains the requirements of DGAC France AD F-
2002-414R3 [and F-2002-415R2], which is superseded, and requires 
repetitive inspections and lubrications of the new THSA P/N.
    The repetitive inspection and lubrication requirements for THSA 
P/N 47172-520 and 47172-530 shall [also] be included in the next 
Airworthiness Limitation Section (ALS) Part 4 revision.
* * * * *
    Corrective actions include replacing the THSA with a new THSA if 
cracks, dents, or corrosion are found, or if the feeler gage has failed 
at any of the four gaps. Other corrective action includes using a 
method approved by the FAA or the EASA (or its delegated agent) for a 
finding of metallic debris, loose nut, damaged or missing lock washers, 
pins and parts, or incorrect installation of items. AD 2005-07-04, 
Amendment 39-14028 (70 FR 16104, March 30, 2005), required repetitive 
inspections for discrepancies. This AD requires, for certain airplanes, 
repetitive inspections for the integrity of the primary and secondary 
load path, and the CSPs. The unsafe condition is the degraded operation 
of the THSA, which could result in reduced controllability of the 
airplane. You may obtain further information by examining the MCAI in 
the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

Request To Use Later Document Revision

    Delta Airlines (Delta) requested that paragraph (j)(2) of the NPRM 
(77 FR 60075, October 2, 2012) refer to Airbus A330 Airworthiness 
Limitations Section (ALS) Part 4--Ageing Systems Maintenance, Revision 
03, dated September 9, 2011; instead of Revision 02, dated December 16, 
2009. Delta stated that Revision 03 of that ALS specifies the 1,000 
flight-hour lubrication threshold and repetitive interval that are 
specified in paragraph (j)(2) of the NPRM, whereas Revision 02 of this 
ALS specifies 700 flight hours for the lubrication threshold and 
repetitive interval.
    We agree that Airbus A330 Airworthiness Limitations Section (ALS) 
Part 4--Ageing Systems Maintenance, Revision 03, dated September 9, 
2011, correctly specifies the lubrication threshold and repetitive 
interval. We have changed paragraph (j)(2) of this AD accordingly. In 
addition, we have changed paragraph (j)(2) of this AD to reference 
Airbus A340 ALS Part 4--Ageing Systems Maintenance, Revision 02, dated 
October 12, 2011; and Revision 03, dated November 15, 2012; for the 
same reason.

Request To Change Wording

    Delta requested that we change the wording in paragraph (l) of the 
NPRM (77 FR 60075, October 2, 2012), which states ``For airplanes 
identified in paragraph (k) of this AD.'' The commenter asked that the 
wording ``identified in'' be replaced with

[[Page 47539]]

``affected by.'' The commenter provided no reason for the change.
    We disagree to change the wording in paragraph (n) in this AD 
(identified as paragraph (l) in the NPRM (77 FR 60075, October 2, 
2012)) as requested by the commenter. However, we have moved the 
content of paragraphs (k)(1), (k)(2), and (k)(3) of the NPRM to new 
paragraph (l) in this AD to clarify the actions and affected airplanes. 
We have also moved the content of paragraph (k)(6) of the NPRM to new 
paragraph (m) of this AD, and re-identified succeeding paragraphs 
accordingly. Finally, in paragraph (n) of this AD, we revised the 
wording to describe the affected airplanes.

Request To Include Additional Part Number

    Delta requested that we include THSA P/N 47172-520 and P/N ``47127-
530'' in paragraph (m) of the NPRM (77 FR 60075, October 2, 2012) as 
applicable part numbers for Model A330 series airplanes.
    We disagree to include THSA P/N 47127-530 as there is no such part 
number. We infer that the commenter meant to specify THSA P/N 47172-
530. THSA P/N 47172-520 and P/N 47172-530 are not included in the MCAI. 
However, all necessary tasks for those THSA part numbers are contained 
in Airbus A330 Airworthiness Limitations Section (ALS) Part 4--Ageing 
Systems Maintenance, Revision 03, dated September 9, 2011; and Airbus 
A340 ALS Part 4--Ageing Systems Maintenance, Revision 02, dated October 
12, 2011, and Revision 03, dated November 15, 2012. The FAA NPRMs to 
mandate these ALS Part 4 documents are pending at this time. Therefore, 
we have not changed this AD in this regard.

Request To Consider Another EASA AD

    Corinne Dayde stated that she ``Cannot see how EASA 2012-0061 is 
considered.''
    We are considering addressing EASA AD 2012-0061R1, dated November 
30, 2012, in a separate FAA AD. We have not changed this AD in this 
regard.

Conclusion

    We reviewed the available data, including the comments received, 
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 changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 60075, October 2, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 60075, October 2, 2012).

Costs of Compliance

    We estimate that this AD will affect about 33 products of U.S. 
registry.
    The actions that are required by AD 2005-07-04, Amendment 39-14028 
(70 FR 16104, March 30, 2005), and retained in this AD take up to 36 
work-hours per product, at an average labor rate of $85 per work-hour. 
Based on these figures, the estimated cost of the retained actions is 
up to $3,060 per product.
    We estimate that it will take about 2 work-hours per product to 
comply with the new basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $5,610, or $170 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this AD.

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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains this AD, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.
