Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2012-0802; Directorate Identifier 2012-NM-124-AD; 
Amendment 39-17145; AD 2011-19-01 R1]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are revising an existing airworthiness directive (AD) that 
applies to all Airbus Model A318, A319, A320, and A321 series 
airplanes. The existing AD currently requires revising the airplane 
flight manual (AFM) to include a procedure intended to address the 
unsafe condition, an inspection of the firewall connector for signs of 
arcing if an integrated drive generator (IDG) (or generator (GEN)) was 
shut down in-flight automatically or using the AFM procedure, and 
corrective action if necessary; and provides an optional terminating 
action for certain AFM revision and inspections. This AD was prompted 
by the potential for an inadvertent error by flightcrew to use the IDG 
switch instead of the GEN switch when doing the AFM display unit 
failure procedure required by the existing AD. This AD retains the 
actions required by the existing AD and clarifies certain terminology. 
We are issuing this AD to prevent transient loss of certain systems, 
which could result in the reduced ability of the flightcrew to cope 
with adverse flight conditions.

DATES: This AD becomes effective August 22, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 
28, 2011 (76 FR 56279, September 13, 2011).
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of August 
13, 2004 (69 FR 45243, July 29, 2004).
    We must receive comments on this AD by September 21, 2012.

SUPPLEMENTARY INFORMATION:

Discussion

    On September 1, 2011, we issued AD 2011-19-01, Amendment 39-16806 
(76 FR 56279, September 13, 2011). That AD required actions intended to 
address an unsafe condition on the products listed above.
    Since we issued AD 2011-19-01, Amendment 39-16806 (76 FR 56279, 
September 13, 2011), we have received information that there is 
potential for an inadvertent error by flightcrew to use the ``IDG'' 
(integrated drive generator) switch instead of the ``GEN'' 
(abbreviation for generator) switch when doing the AFM display unit 
failure procedure in this AD that requires turning off the integrated 
drive generator under certain conditions. We find that it is necessary 
to clarify our intent with the use of the acronym ``IDG'' in relation 
to ``GEN,'' and to revise paragraphs (h), (i), and (k) of this AD to 
refer to ``GEN.''

FAA's Determination and Requirements of this AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
transient loss of certain systems could result in the reduced ability 
of the flightcrew to cope with adverse flight conditions. Therefore, we 
determined that notice and opportunity for public comment before 
issuing this AD are impracticable and that good cause exists for making 
this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2012-0802; Directorate 
Identifier 2012-NM-124-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic,

[[Page 46930]]

environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about 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 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.
