14 CFR Part 39

[Docket No. FAA-2012-1039; Directorate Identifier 2011-NM-275-AD; 
Amendment 39-17491; AD 2013-13-03]
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 certain 
Airbus Model A319-112, -113, and -132 airplanes; Model A320-211, -212, 
-214, -231, and -232 airplanes; and Model A321-111 and -131 airplanes. 
This AD was prompted by a report of two fatigue cracks on the left-hand 
and right-hand sides of the continuity fittings at the front windshield 
lower framing on a Model A319 series airplane. This AD requires a high 
frequency eddy current (HFEC) inspection for any cracking on the left-
hand and right-hand sides of the windshield central lower node 
continuity fittings, and repair if necessary. We are issuing this AD to 
detect and correct cracking of the windshield central lower node 
continuity fittings, which could reduce the structural integrity of the 
airplane.

DATES: This AD becomes effective August 14, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 14, 
2013.

ADDRESSES: You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

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

[[Page 41281]]

NPRM was published in the Federal Register on October 4, 2012 (77 FR 
60658). The European Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Community, has 
issued EASA Airworthiness Directive 2011-0231, dated December 9, 2011 
(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:

    One operator reported finding two fatigue cracks on continuity 
fittings at left-hand (LH) and right-hand (RH) sides at the front 
windshield lower framing on an A319 aeroplane on which Airbus 
modification (mod.) 22058 had been embodied in production. Airbus 
mod. 22058 (which is included in Airbus mod. 21999) was introduced 
to improve the fatigue strength of the windshield front framing by 
increasing the thickness of framing flanges adjacent to the 
concerned fittings.
    Further analyses have demonstrated that the damage tolerance and 
fatigue requirements of JAR 25.571 (b) are not met on aeroplanes in 
post-mod. 22058 configuration.
    This condition, if not detected and corrected, could reduce the 
structural integrity of the affected aeroplanes.

Required actions include an HFEC inspection for any cracking on the 
left-hand and right-hand sides of the windshield central lower node 
continuity fittings, and repair if necessary. 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 Revise HFEC Inspection Requirement

    Airbus requested that the one-time HFEC inspection in paragraph (g) 
of the NPRM (77 FR 60658, October 4, 2012) be revised in anticipation 
of further rulemaking by the EASA, which would mandate the 
airworthiness limitation inspection task and would correspond with the 
one-time HFEC inspection.
    We disagree with Airbus's request. We have determined that 
publishing this final rule without any further delay is in the interest 
of safety of the flying public. However, we will consider additional AD 
rulemaking, if appropriate, in the future. We have not revised this 
final rule in this regard.

Request for Approval of Repair

    Airbus requested consideration that each Airbus Repair Approval 
Sheet (RAS) be approved under ``AIRBUS DOA EASA.21J.031,'' provided 
that this is done after cracking is reported. Airbus stated that this 
would be an approved method for repair as required by paragraph (g) of 
the NPRM (77 FR 60658, October 4, 2012).
    We agree. Airbus is an EASA-delegated agent; therefore, a RAS 
approved under Airbus Design Organization Approval (DOA) EASA.21J.031 
would be a method of compliance for a repair required by this AD. We 
have not changed the final rule in this regard.

Request To Update Address for the Manufacturer

    Airbus requested that the address for the manufacturer be updated. 
Airbus stated that in paragraph (k)(2) of the NPRM (77 FR 60658, 
October 4, 2012), ``EAS'' should be replaced with ``EIAS.''
    We agree with Airbus's request to update the manufacturer's 
address. Paragraphs (k)(2) and (l)(3) of this final rule have been 
updated accordingly.

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 change described previously--and minor editorial 
changes. We have determined that these changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (77 FR 60658, October 4, 2012) for correcting the unsafe 
condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 60658, October 4, 2012).

Costs of Compliance

    We estimate that this AD will affect 105 products of U.S. registry. 
We also estimate that it will take about 20 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 to the U.S. operators to be $178,500, or $1,700 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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
