14 CFR Part 39

[Docket No. FAA-2012-1034; Directorate Identifier 2011-NM-051-AD; 
Amendment 39-17383; AD 2013-05-11]
RIN 2120-AA64

Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for certain Airbus Model A318, A319, A320, and A321 series airplanes. 
That AD currently requires one-time and repetitive inspections of 
specific areas and, when necessary, corrective actions for those 
rudders where production rework has been identified. This new AD adds 
airplanes with certain rudders to the AD applicability; changes an 
inspection type for certain reinforced rudder areas; requires pre-
inspections and repairs if needed; and requires permanent restoration 
of vacuum loss holes. This AD also requires additional inspections for 
certain rudders and repair if needed, and requires replacement of 
certain rudders with new rudders. This AD was prompted by reports of 
surface defects on rudders that were the result of debonding between 
the skin and honeycomb core. We are issuing this AD to detect and 
correct extended de-bonding, which might degrade the structural 
integrity of the rudder. The loss of the rudder leads to degradation of 
the handling qualities and reduces the controllability of the airplane.

DATES: This AD becomes effective July 26, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 26, 
2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of 
December 10, 2010 ((75 FR 68181, November 5, 2010); corrected (75 FR 
78883, December 17, 2010)).

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. 
That NPRM was published in the Federal Register on October 2, 2012 (77 
FR 60064), and proposed to supersede AD 2010-23-07, Amendment 39-16496 
((75 FR 68181, November 5, 2010); corrected (75 FR 78883, December 17, 
2010)). That 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 2010-0164, dated August 5, 2010 
(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    Surface defects were visually detected on the rudder of one A319 
and one A321 in-service aeroplane.
    Investigation has determined that the defects reported on both 
rudders corresponded to areas that had been reworked in production. 
The investigation confirmed that the defects were a result of de-
bonding between the skin and honeycomb core.
    An extended de-bonding, if not detected and corrected, may 
degrade the structural integrity of the rudder. The loss of the 
rudder leads to degradation of the handling qualities and reduces 
the controllability of the aeroplane.
    EASA AD 2009-0141 required inspections of specific areas and, 
when necessary, the application of corrective actions for those 
rudders where production reworks have been identified.
    This [EASA] AD retains the requirements of EASA AD 2009-0141 
(addressing the populations of rudders affected by AOT A320-55-
1038), which is superseded, and requires:

--a local ultrasonic inspection for reinforced area instead of the 
local thermography inspection, which is maintained for non-
reinforced areas, and
--additional work performance for rudders on which this thermography 
inspection has been performed in the reinforced area, and
--additional work performance for some rudders on which an 
additional area requiring inspections is defined.

    This [EASA] AD also addresses the populations of rudders 
affected by AOT A320-55-1039 and Airbus SB A320-55-1035, A320-55-
1036 and A320-55-1037 which were not included in EASA AD 2009-0141.

Part number (P/N) D554 71000 020 00, serial number (S/N) TS-1494; and 
P/N D554 71002 000 00 0002, S/N TS-2212; are listed in Appendix A of 
the MCAI. These two items are included in this AD, because they were 
not listed in previous AD 2010-23-07, Amendment 39-16496 ((75 FR 68181, 
November 5, 2010); corrected (75 FR 78883, December 17, 2010)). This AD 
requires the permanent restoration of vacuum loss holes and does not 
allow the temporary restoration with self-adhesive patches, or 
temporary restoration with resin that is specified in the MCAI. 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.

Support for the NPRM (77 FR 60064, October 2, 2012)

    United Airlines (UAL) stated that it generally agrees with the 
proposed requirements of the NPRM (77 FR 60064, October 2, 2012).

Request for Additional Compliance Time

    UAL requested that we add ``a grace period from the AD effective 
date'' for the compliance time for the inspection specified in 
paragraph (y) of the NPRM (77 FR 60064, October 2, 2012). UAL

[[Page 37438]]

stated that some rudders used in sampling inspections may be over the 
compliance threshold specified in paragraph (y) of the NPRM. UAL 
proposed an alternative method of inspection for the affected rudders.
    We partially agree. We agree with adding a compliance time of 30 
days after the effective date of this AD for the inspection specified 
in paragraph (y) of this AD. We disagree with the commenter's proposed 
alternate method of inspection because no justification was submitted 
to substantiate that this alternate inspection method would adequately 
address the identified unsafe condition. Under the provisions of 
paragraph (ff) of this AD, we will consider requests for approval of an 
alternate method of compliance (AMOC) if sufficient data are submitted 
to substantiate that an alternate inspection method would provide an 
acceptable level of safety.

Request To Correct Contact Information

    Airbus requested that we change certain contact information. Airbus 
stated that paragraphs (j) and (dd) of the NPRM (77 FR 60064, October 
2, 2012) should state that, for negative findings, submit the report to 
SEES1, Customer Services, fax +33 (0)5 61 93 36 14. Airbus also 
requested that we replace EAS with EIAS in paragraph (gg)(2) of the 
NPRM.
    We agree and have changed paragraphs (j) and (dd) of this AD 
accordingly. We have also included the term EIAS in paragraphs (gg)(2) 
and (hh)(5) of this AD.

Request for Permanent Repair Approval

    Airbus requested that we consider each Airbus Repair Approval Sheet 
(RAS) approved under Airbus Design Organization Approval (DOA) 
EASA.21J.031, provided to each rudder after damage is reported, as an 
approved method for permanent repair of rudder damage.
    We agree. Airbus is an EASA delegated agent and therefore a RAS 
approved under Airbus Design Organization Approval (DOA) EASA.21J.031 
would be method of compliance for a repair required by this AD. We have 
not changed this AD in this regard.

Request To Clarify Temporary Repairs

    Airbus requested that we clarify why the NPRM (77 FR 60064, October 
2, 2012) does not allow the temporary restoration with self-adhesive 
patches, or the temporary restoration with resin, which are specified 
in the MCAI.
    We agree to clarify. Airbus All Operators Telex (AOT) A320-55A1038, 
Revision 02, dated September 28, 2009, does not provide specific 
procedures for operators to apply and inspect temporary restoration of 
vacuum loss inspection holes. This service information also does not 
specify pass/fail criteria for the detailed visual inspections 
associated with temporary repairs. This service information states that 
details of the hole restoration are provided in technical adaptations. 
We do not have access to technical adaptations for incorporating the 
technical adaptations by reference. Under the provisions of paragraph 
(ff) of this AD, we will consider requests for approval of an AMOC if 
sufficient data are submitted to specify an acceptable process for 
temporary repairs and that those temporary repairs would provide an 
acceptable level of safety. We have not changed the AD in this regard.

Additional Changes Made to This AD

    In the NPRM (77 FR 60064, October 2, 2012), we included rudders P/N 
D554 71000 020 00, S/N TS-1494; and P/N D554 71002 000 00 0002, S/N TS-
2212 in table 6 to paragraph (c) of the NPRM. In this final rule, we 
have specified these part/serial numbers in paragraphs (c), (aa), and 
(ee) of this AD, and removed table 6 to paragraph (c) of this AD.
    We have also revised this final rule to change tables 4a, 4b, 5a, 
and 5b to figures 1, 2, 3, and 4 of this AD; we made no change to the 
content of those tables. These changes were made for formatting 
purposes only.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
the 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 60064, 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 60064, October 2, 2012).

Costs of Compliance

    We estimate that this AD will affect about 721 products of U.S. 
registry.
    The actions that are required by AD 2010-23-07, Amendment 39-16496 
((75 FR 68181, November 5, 2010); corrected (75 FR 78883, December 17, 
2010)), and retained in this AD take about 11 work-hours per product, 
at an average labor rate of $85 per work hour. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
the currently required actions on U.S. operators to be $674,135, or 
$935 per product.
    We estimate that it will take about 11 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 the AD on U.S. operators to be $674,135, or $935 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 12 work-hours and require parts costing $10,000, for a cost 
of $11,020 per product. We have no way of determining the number of 
products that may need these actions.

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

[[Page 37439]]

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.

(d) Subject

    Air Transport Association (ATA) of America Code 55, Stabilizers.

(e) Reason

    This AD was prompted by reports of surface defects on rudders 
that were the result of debonding between the skin and honeycomb 
core. We are issuing this AD to detect and correct extended de-
bonding, which might degrade the structural integrity of the rudder. 
The loss of the rudder leads to degradation of the handling 
qualities and reduces the controllability of the airplane.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Retained Repetitive Inspections of Rudders With a Core Density of 
24 kg/m\3\

    This paragraph restates the requirements of paragraph (g) of AD 
2010-23-07, Amendment 39-16496 ((75 FR 68181, November 5, 2010); 
corrected (75 FR 78883, December 17, 2010)). For rudders identified 
in table 1 to paragraph (c) of this AD with a honeycomb core density 
of 24 kg/m\3\ (rudder P/N D554 71000 010 00 having affected rudder 
S/Ns TS-1069 and TS-1090, and rudder P/N D554 71000 012 00 having
