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 A330-200, A330-200 Freighter, and A330-300 series 
airplanes; and Model A340-200, A340-300, A340-500, and A340-600 series 
airplanes. This AD was prompted by a non-connection of the constant 
speed motor/generator (CSM/G) during a final assembly operational test. 
This AD requires a detailed inspection of the connector wires for 
connector 1XE-A of the generator control unit (GCU)-CSM/

[[Page 33046]]

G for discrepancies (evidence of arcing or overheating damage), and 
related investigative and corrective actions if necessary. We are 
issuing this AD to detect and correct incorrect locking of contacts 
into connector 1XE-A of the GCU-CSM/G, which could result in a loss of 
contact continuity and lead to the CSM/G not operating, which, in 
conjunction with an emergency electrical configuration loss of the main 
electrical system or total engine flameout, could adversely affect the 
airplane's safe flight.

DATES: This AD becomes effective July 15, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publications listed in this AD as of July 15, 
2014.

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-
200, A330-200 Freighter, and A330-300 series airplanes; and Model A340-
200, A340-300, A340-500, and A340-600 series airplanes. The NPRM 
published in the Federal Register on December 26, 2013 (78 FR 78294).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2013-0175, dated August 2, 2013 (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:

    During Final Assembly Line tests on an A330 aeroplane, the 
Generator Control Unit--Constant Speed Motor/Generator (GCU-CSM/G) 
failed the operational test.
    Investigations revealed that it is due to incorrect locking of 
some contacts (pins) into the GCU-CSM/G connector 1XE-A. An 
inspection of other aeroplanes confirmed this production quality 
issue. Among the 26 pins used in GCU-CSM/G connector 1XE-A, 6 pins 
have been identified as potentially affected by this issue.
    A badly locked contact could result in a loss of continuity 
[non-connection] and lead to the non-operation of the CSM/G.
    This condition, if not detected and corrected, and in 
conjunction with either an emergency electrical configuration loss 
of main electrical system or total engine flame out, could 
jeopardize the aeroplane's safe flight.
    To address this condition, Airbus developed Alert Operator 
Transmission (AOT) A24L001-13, to provide instructions for a one-
time inspection.
    For the reasons described above, this AD requires a one-time 
[detailed] inspection of the potentially affected connector wires of 
GCU-CSM/G connector 1XE-A and, depending on [the] finding, 
accomplishment of [a related investigative action] and applicable 
corrective actions.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-1031-0002.

Revised Service Information

    Since the NPRM (78 FR 78294, December 26, 2013) was published, we 
have received Airbus Alert Operators Transmission A24L001-13, Revision 
01, dated March 6, 2014. We have determined that this service 
information does not add any additional actions to those proposed in 
the NPRM, therefore, we have revised paragraph (g) of this AD to refer 
to that service information. We have also added a new paragraph (h) to 
this AD to provide credit for actions performed before the effective 
date of this AD using Airbus Alert Operators Transmission A24L001-13, 
dated July 25, 2013, and redesignated the subsequent paragraphs 
accordingly. Additionally, we have added paragraph (k), Material 
Incorporated by Reference, to the end of this AD.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM (78 FR 
78294, December 26, 2013) and the FAA's response to that comment.

Request To Clarify What Prompted the NPRM (78 FR 78294, December 26, 
2013)

    Airbus requested clarification in the SUMMARY section and paragraph 
(e) of the NPRM (78 FR 78294, December 26, 2013). Airbus stated that it 
was not ``failure of the generator control unit-constant speed motor/
generator during a final assembly operational test'' that caused the 
unsafe condition, but a non-connection of the CSM/G during an 
operational test in the final assembly line. Investigations revealed an 
incorrect locking of some contacts into connector 1XE-A of the GCU-CSM/
G.
    We agree to revise the SUMMARY section and paragraph (e) of this 
final rule to state that this AD was prompted by a non-connection of 
the CSM/G during a final assembly operational test.

Changes to This Final Rule

    Paragraphs (g)(1) and (g)(2) in the NPRM (78 FR 78294, December 26, 
2013) have been combined into paragraph (g) in this final rule.

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 (78 FR 78294, December 26, 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 78294, December 26, 2013).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 76 airplanes of U.S. registry.
    We also estimate that it will take about 1 work-hour 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 $6,460, or $85 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 1 work-hour and require parts costing up to $17,314, for a 
cost of up

[[Page 33047]]

to $17,399 per product. We have no way of determining the number of 
aircraft that might need this action.

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.
