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 certain 
Airbus Model A330-300, A340-200, and A340-300 series airplanes. This AD 
was prompted by a report of substantial inner skin disbonding damage 
found on a rudder. This AD requires performing an inspection for damage 
of certain rudders, and repair if necessary. We are issuing this AD to 
detect and correct damage of the rudder, which could result in reduced 
structural integrity of the rudder.

DATES: This AD becomes effective March 6, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 6, 
2015.

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 certain Airbus Model A330-
300, A340-200, and A340-300 series airplanes. The NPRM published in the 
Federal Register on August 13, 2014 (79 FR 47387).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2013-0270R1, dated November 27, 2013 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for Airbus Model A330-
300, A340-200, and A340-300 series airplanes. The MCAI states:

    One A310 operator found substantial inner skin disbonding damage 
on a rudder. The results of the subsequent investigation revealed 
that the most probable cause of this damage was a blunt impact with 
no visible damage from outside during the rudder handling. Such type 
of damage might grow with pressure variation during ground-air-
ground cycles, and tests performed with other rudders showed a rapid 
propagation of damage during artificial pressure cycling.
    This condition, if not detected and corrected, could affect the 
structural integrity of the rudder.
    For the affected A310 and A300-600 aeroplanes, EASA issued AD 
2013-0039 [http://ad.easa.europa.eu/blob/easa_ad_2013_0039.pdf/AD_2013-0039], to address and correct this potential unsafe 
condition.
    As potentially affected rudders can also be installed on A330 
and A340 aeroplanes, Airbus issued Alert Operator Transmission (AOT) 
A55L001-12 [dated December 20, 2012], pending Aircraft Maintenance 
Manual (AMM) 27-21-41 PB401 revision, to provide operators with 
updated rudder handling procedures.
    EASA issued AD 2013-0270 [http://ad.easa.europa.eu/blob/easa_ad_2013_0270.pdf/AD_2013-0270], to require identification of 
affected rudders P/N [part number] A55471500XXX (where XXX stands 
for any numerical value), a one-time ultrasonic test (UT) inspection 
of each affected rudder to detect signs of disbonding and, depending 
on findings, accomplishment of applicable corrective action(s).
    After [EASA] AD 2013-0270 was issued, operators commented that 
the batch of rudders to be inspected was not correctly defined.
    For the reason described above, [EASA] AD 2013-0270 is revised 
to clarify that no action is required for rudders previously 
inspected in accordance with Airbus Service Bulletin (ASB) A330-55-
3038 or SB A340-55-4034 [which are required by FAA AD 2009-10-11, 
Amendment 39-15907 (74 FR 23622, May 20, 2009)], as applicable to 
aeroplane model, provided the rudder has never been removed and/or 
installed on an aeroplane since this inspection.

    Required actions include an elasticity of laminate checker 
inspection of the rudder side panel to detect external and internal 
disbonding, and a woodpecker or tap test inspection to detect external 
disbonding, and repair if necessary. You may examine the MCAI in the AD 
docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0525-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM (79 FR 
47387, August 13, 2014) and the FAA's response.

Request To Correct Certain Document Numbers

    Lufthansa Technik (Lufthansa) asked that we correct certain 
document

[[Page 5033]]

numbers for the service information identified in paragraph (h) of the 
NPRM (79 FR 47387, August 13, 2014). Lufthansa stated that paragraph 
(h) of the NPRM incorrectly refers to Airbus Service Bulletins A300-55-
3038 and A310-55-4034, instead of Airbus Service Bulletins A330-55-3038 
and A340-55-4034, both dated November 7, 2007.
    We agree with the commenter for the reason provided. We have 
corrected the document numbers for the service information identified 
in paragraph (h) of this AD accordingly.

Compliance Time Change

    We revised the compliance time in paragraph (g) of this AD for the 
part numbers and serial numbers that cannot be identified from ``before 
further flight'' to ``within 3 months after the effective date of this 
AD.'' We have also revised the compliance time in paragraph (h) of this 
AD for the ultrasonic test inspection from ``before further flight'' to 
``within 3 months after the effective date of this AD.'' This 
compliance time corresponds to the compliance time specified in the 
MCAI. We have determined this compliance time will provide an 
acceptable level of safety.

Conclusion

    We reviewed the relevant data, considered the comment 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 minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 47387, August 13, 2014) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 47387, August 13, 2014).

Related Service Information

    Airbus has issued Alert Operators Transmission A55L001-12, dated 
December 20, 2012. The service information describes procedures for an 
inspection for damage of certain rudders. You can find this information 
at http://www.regulations.gov by searching for and locating Docket No. 
FAA-2014-0525.

Costs of Compliance

    We estimate that this AD affects 74 airplanes of U.S. registry.
    We also estimate that it will take about 12 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $0 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $75,480, or $1,020 per product.
    We have received no definitive data that would enable us to provide 
a cost estimate 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.
