14 CFR Part 39

[Docket No. FAA-2013-0665; Directorate Identifier 2012-NM-082-AD; 
Amendment 39-17634; AD 2013-22-02]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A330-300 series airplanes and Model A340-200 and -300 
series airplanes. This AD was prompted by reports of corrosion found on 
certain trimmable horizontal stabilizer actuators (THSA), affecting the 
ballscrew lower splines between the tie bar and the screw-jack. This AD 
requires repetitive detailed inspections for corrosion of certain 
THSAs, ballscrew integrity tests if necessary; and replacing any 
affected THSA with a serviceable or new and improved THSA, if 
necessary. We are issuing this AD to detect and correct corrosion of 
the THSAs, which could lead, in the case of ballscrew rupture, to the 
loss of transmission of THSA torque loads from the ballscrew to the 
tie-bar, prompting THSA blowback, and possibly resulting in loss of 
control of the airplane.

DATES: This AD becomes effective December 5, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 5, 
2013.

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 the specified products. The 
NPRM published in the Federal Register on August 1, 2013 (78 FR 46543). 
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 2012-0061R1, dated November 30, 2012 (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:

    Some Trimmable Horizontal Stabilizer Actuators (THSA), Part 
Number (P/N) 47147-500, have been found with corrosion, affecting 
the ballscrew lower splines between the tie bar and the screw-jack.
    The results of the technical investigations have identified that 
the corrosion was caused by a combination of:

--Contact/friction between the tie bar and the inner surface of the 
ballscrew leading to the removal of Molykote (corrosion protection) 
at the level of the tie bar splines,
--Humidity ingress initiating surface oxidation starting from areas 
where Molykote is removed, and
--Water retention in THSA lower part leading to corrosion spread out 
and to the creation of a brown deposit (iron oxide).

    The results of the technical investigations have also concluded 
that THSA P/N 47147-500 and P/N 47147-700 ballscrews might be 
affected by this corrosion issue.
    THSA P/N 47147-400 ballscrews might be affected as well, but 
should no longer be in service, and modified into P/N 47147-500, as 
required by EASA AD 2010-0192 and EASA AD 2010-0193 [and as required 
by FAA AD 2005-07-04, Amendment 39-14028 (70 FR 16104, March 30, 
2005)].
    This condition, if not detected and corrected, may lead, in case 
of ballscrew rupture, to loss of transmission of THSA torque loads 
from the ballscrew to the tie-bar, prompting THSA blowback, possibly 
resulting in loss of control of the aeroplane.
    To correct this potential unsafe condition, EASA issued AD 2012-
0061 to require repetitive [detailed] visual inspections of the 
ballscrew lower splines of THSA having P/N 47147-500 or P/N 47147-
700 to detect corrosion and, depending on findings [ballscrew 
integrity tests], the accomplishment of applicable corrective 
actions [replacing the affected THSA with a serviceable or improved 
THSA].
    Since that [EASA] AD [2012-0061] was issued, Airbus published 
new Service Bulletin (SB) A330-27-3194 or Airbus SB A340-27-4187 
(Airbus modification 202802), which allow installation in service of 
an improved THSA P/N 47172-530.
    For the reasons described above, this [EASA] AD [2012-0061R1] is 
revised to specify that installation of THSA P/N 47172-530 is an 
alternative (optional) terminating action to the repetitive 
inspections required by this AD.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-0665-0002.

Relevant Service Information

    We have received Airbus Mandatory Service Bulletins A330-27-3179 
and A340-27-4175, both Revision 01, both dated June 13, 2013; which 
specify no additional work. We have updated paragraphs (g), (i), and 
(n) of this final rule to reference this service information. We have 
also added new paragraph (m) to this final rule to allow credit for the 
actions specified in paragraphs (g), (i), and (n) of this final rule, 
if those actions were performed before the effective date of this AD 
using Airbus Mandatory Service Bulletins A330-27-3179, dated February 
14, 2012; or A340-27-4175, dated February 14, 2012. Subsequent 
paragraphs have been re-designated accordingly.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 46543, August 1, 
2013) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the

[[Page 65188]]

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 (78 FR 46543, August 1, 2013) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 46543, August 1, 2013).

Costs of Compliance

    Based on the service information, we estimate that this AD affects 
about 30 products of U.S. registry. We also estimate that it takes 
about 6 work-hours per product to comply with the 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 
$15,300, or $510 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 13 work-hours and require parts costing up to $722,556 for a 
cost of up to $723,661 per product. We have no way of determining the 
number of products that may need these actions.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information 
Collection Clearance Officer, AES-200.

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.

Systems Service Bulletin 47147-27-18, dated February 17, 2012. 
Repeat the inspection thereafter at intervals not to exceed 24 
months until the modification specified in paragraph (k) is done.
    (1) For any THSA, which, as of the effective date of this AD, 
has accumulated less than 156 months since its first flight on an 
airplane as THSA P/N 47147-400, or since its first flight after the 
modification specified in the Accomplishment Instructions of Airbus 
Mandatory Service Bulletin A330-27-3052 or A340-27-4059 has been 
done: Do the inspection before the accumulation of 156 months but 
not before the accumulation of 132 months since first flight on an 
airplane as THSA P/N 47147-400, or since the THSA's first flight 
after the modification specified in the Accomplishment Instructions 
of Airbus Mandatory Service Bulletin A330-27-3052 or A340-27-4059 
has been done; or within 3 months after the effective date of this 
AD; whichever occurs later.
    (2) For any THSA, which, as of the effective date of this AD, 
has accumulated 156 months or more since its first flight on an 
airplane as THSA P/N 47147-400, or since its first flight after the 
modification specified in the Accomplishment Instructions of Airbus 
Mandatory Service Bulletin A330-27-3052 or A340-27-4059 has been 
done: Do the inspection within 3 months after the effective date of 
this AD.

(h) Compliance Time Exceptions

    (1) Some THSAs having P/N 47147-500 (and further derivative with 
P/N 47147-700) were originally THSA P/N 47147-400 and were 
subsequently modified in service. In this case, the time accumulated 
by any THSA must be calculated from the first installation on 
airplanes as THSA P/N 47147-400.
    (2) Some THSAs having P/N 47147-500 (and further derivative with 
P/N 47147-700) were originally THSA P/N 47147-200, -210, -213, -300, 
-303, or -350 and were subsequently modified in service as specified 
in the Accomplishment Instructions of Airbus Mandatory Service 
Bulletin A330-27-3052 or A340-27-4059. In this case, the time 
accumulated by any THSA must be calculated from the first flight on 
an airplane after the THSA has been modified as specified in the 
Accomplishment Instructions of Airbus Mandatory Service Bulletin 
A330-27-3052 or A340-27-4059.

(i) Ballscrew Integrity Test and Corrective Actions
