ACTION: Final rule; request for comments. We are adopting a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: In service experience has shown a number of events of pin to socket arcing at the Integrated Drive Generator (IDG) feeder cable pylon/nacelle interface connector. The fretting corrosion phenomenon was identified to be the root cause of the pin to socket arcing. Investigation has identified a nonoptimised electrical harness installation as a contributing factor to this phenomenon that could lead to electrical arcs with possible electrical flickering. * * * * * [S]ome operators reported cases of Display Unit (DU) flickering, despite the fact that the engines installed did not belong to the affected batch, and that these aeroplanes had been modified to incorporate one of * * * two terminating actions, * * *. [S]ome intermittent electrical power supply interruptions may not be detectable by the electrical power monitoring system, thereby preventing an automatic disconnection of the failed generator. * * * * * The unsafe condition is transient loss of certain systems, which could result in the reduced ability of the flightcrew to cope with adverse flight conditions. This AD requires actions that are intended to address the unsafe condition described in the MCAI. DATES: This AD becomes effective September 28, 2011. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of September 28, 2011.

SUPPLEMENTARY INFORMATION: Discussion On July 16, 2004, we issued AD 2004– 15–14, Amendment 39–13748 (69 FR 45243, July 29, 2004), which ´ ´ corresponded to Direction Generale de l’Aviation Civile (DGAC) (the aviation authority for France) AD F–2004–074, dated May 26, 2004. That FAA AD required revising the airplane flight manual (AFM) to include a procedure intended to address an unsafe condition on Airbus Model A319–131, –132, and –133; A320–231, –232, and –233; and A321–131 and –231 series airplanes except those airplanes on which Airbus Modification 32943 has been incorporated in production. That FAA AD also required an inspection of the firewall connector for signs of arcing if E:\FR\FM\13SER1.SGM 13SER1 56280 Federal Register / Vol. 76, No. 177 / Tuesday, September 13, 2011 / Rules and Regulations mstockstill on DSK4VPTVN1PROD with RULES an integrated drive generator (IDG) was shut down in-flight automatically or using the AFM procedure, and corrective action as applicable. That FAA AD also included an optional terminating action to replace the IDG harnesses and connectors. The inspection and replacement actions were not required or provided in French AD F–2004–074. Since we issued AD 2004–15–14, Amendment 39–13748 (69 FR 45243, July 29, 2004), some operators reported cases of display unit (DU) flickering, despite being modified in production, or in service using certain service information. Therefore, to address the unsafe condition associated with DU flickering, Airbus developed a new AFM procedure. We have determined that this new AFM procedure is necessary to address the identified unsafe condition. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2011–0142, dated July 25, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: In service experience has shown a number of events of pin to socket arcing at the Integrated Drive Generator (IDG) feeder cable pylon/nacelle interface connector. The fretting corrosion phenomenon was identified to be the root cause of the pin to socket arcing. Investigation has identified a nonoptimised electrical harness installation as a contributing factor to this phenomenon that could lead to electrical arcs with possible electrical flickering. These incidents may cause the following symptoms during flight: —Intermittent flickering of display units, e.g. primary flight display, navigation display, electronic centralized aircraft monitoring (ECAM) and/or multipurpose control display unit (MCDU), —Transient disconnection of several systems (auto pilot, yaw damper, auto throttle), triggering of aircraft system warnings and/ or flags, —Loss of IDG power supply on the affected engine, and/or —Flickering of cabin lights. The Aircraft Flight Manual (AFM) Temporary Revision (TR) 4.02.00/20 was issued as a procedure to be applied in such case. Consequently, EASA AD 2006–0280, which superseded the DGAC France AD F– 2004–074 [which corresponds to FAA AD 2004–15–14, Amendment 39–13748 (69 FR 45243, July 29, 2004)], required the amendment of the AFM to impose the limitations as detailed in AFM TR 4.02.00/20 for aeroplanes with certain engines (limited batch of engines, identified by serial number) installed. After the introduction of this AFM TR, some operators reported cases of Display VerDate Mar<15>2010 15:54 Sep 12, 2011 Jkt 223001 Unit (DU) flickering, despite the fact that the engines installed did not belong to the affected batch, and that these aeroplanes had been modified to incorporate one of the two terminating actions, Airbus Service Bulletin (SB) A320–71–1030 (Airbus modification (mod.) 34982) and SB A320–71–1034 (Airbus mod. 32943). The investigations of these occurrences revealed some intermittent electrical power supply interruptions. Analysis showed that these interruptions may fluctuate within the electrical protection limits and in some rare occasions, may affect some of the connected aeroplanes systems. As a consequence, some intermittent electrical power supply interruptions may not be detectable by the electrical power monitoring system, thereby preventing an automatic disconnection of the failed generator. To address this issue, Airbus has issued a new AFM procedure, applicable to all aeroplanes. This ‘‘DISPLAY UNIT FAILURE’’ procedure, which replaces the one contained in AFM TR 4.02.00/20, allows the flight crew to determine the affected generator, select it OFF and reset the rudder trim. For the reasons described above, this AD, which supersedes EASA AD 2006–0280, requires amendment of the applicable AFM to ensure that the flight crew applies the appropriate operational procedure. The unsafe condition is transient loss of certain systems, which could result in the reduced ability of the flightcrew to cope with adverse flight conditions. This AD also expands the applicability of AD 2004–15–14, Amendment 39– 13748 (69 FR 45243, July 29, 2004), by including all Model A318, A319, A320, and A321 series airplanes. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Temporary Revision TR112, Issue 1.1, dated November 29, 2010, to the Airbus A318/ A319/A320/A321 Airplane Flight Manual. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. 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. PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 Differences Between the AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the AD. 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 of the additional in-service events of DU flickering on Model A318, A319, A320, and A321 series airplanes that were not included in the applicability of FAA AD 2004–15–14, Amendment 39–13748 (69 FR 45243, July 29, 2004), or on which the terminating actions of paragraph (h) of that AD were done. 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–2011–0917; Directorate Identifier 2011–NM–157– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, 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 https:// www.regulations.gov, including any personal information you provide. We E:\FR\FM\13SER1.SGM 13SER1 Federal Register / Vol. 76, No. 177 / Tuesday, September 13, 2011 / Rules and Regulations will also post a report summarizing each substantive verbal contact we receive about this AD. 1. The authority citation for part 39 continues to read as follows: ■ 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); and 3. 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. mstockstill on DSK4VPTVN1PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above that would supersede an existing AD. This AD 
results from mandatory continuing airworthiness information (MCAI) 
originated by an aviation authority of another country to identify and 
correct an unsafe condition on an aviation product. The MCAI describes 
the unsafe condition as:

    In service experience has shown a number of events of pin to 
socket arcing at the Integrated Drive Generator (IDG) feeder cable 
pylon/nacelle interface connector. The fretting corrosion phenomenon 
was identified to be the root cause of the pin to socket arcing.
    Investigation has identified a non-optimised electrical harness 
installation as a contributing factor to this phenomenon that could 
lead to electrical arcs with possible electrical flickering.

* * * * *
    [S]ome operators reported cases of Display Unit (DU) flickering, 
despite the fact that the engines installed did not belong to the 
affected batch, and that these aeroplanes had been modified to 
incorporate one of * * * two terminating actions, * * *.
    [S]ome intermittent electrical power supply interruptions may 
not be detectable by the electrical power monitoring system, thereby 
preventing an automatic disconnection of the failed generator.

* * * * *

The unsafe condition is transient loss of certain systems, which could 
result in the reduced ability of the flightcrew to cope with adverse 
flight conditions. This AD requires actions that are intended to 
address the unsafe condition described in the MCAI.

DATES: This AD becomes effective September 28, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of September 28,

SUPPLEMENTARY INFORMATION: 

Discussion

    On July 16, 2004, we issued AD 2004-15-14, Amendment 39-13748 (69 
FR 45243, July 29, 2004), which corresponded to Direction 
G[eacute]n[eacute]rale de l'Aviation Civile (DGAC) (the aviation 
authority for France) AD F-2004-074, dated May 26, 2004. That FAA AD 
required revising the airplane flight manual (AFM) to include a 
procedure intended to address an unsafe condition on Airbus Model A319-
131, -132, and -133; A320-231, -232, and -233; and A321-131 and -231 
series airplanes except those airplanes on which Airbus Modification 
32943 has been incorporated in production. That FAA AD also required an 
inspection of the firewall connector for signs of arcing if

[[Page 56280]]

an integrated drive generator (IDG) was shut down in-flight 
automatically or using the AFM procedure, and corrective action as 
applicable. That FAA AD also included an optional terminating action to 
replace the IDG harnesses and connectors. The inspection and 
replacement actions were not required or provided in French AD F-2004-
074.
    Since we issued AD 2004-15-14, Amendment 39-13748 (69 FR 45243, 
July 29, 2004), some operators reported cases of display unit (DU) 
flickering, despite being modified in production, or in service using 
certain service information. Therefore, to address the unsafe condition 
associated with DU flickering, Airbus developed a new AFM procedure. We 
have determined that this new AFM procedure is necessary to address the 
identified unsafe condition. The European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, has issued EASA Airworthiness Directive 2011-0142, 
dated July 25, 2011 (referred to after this as ``the MCAI''), to 
correct an unsafe condition for the specified products. The MCAI 
states:

    In service experience has shown a number of events of pin to 
socket arcing at the Integrated Drive Generator (IDG) feeder cable 
pylon/nacelle interface connector. The fretting corrosion phenomenon 
was identified to be the root cause of the pin to socket arcing.
    Investigation has identified a non-optimised electrical harness 
installation as a contributing factor to this phenomenon that could 
lead to electrical arcs with possible electrical flickering.
    These incidents may cause the following symptoms during flight:
--Intermittent flickering of display units, e.g. primary flight 
display, navigation display, electronic centralized aircraft 
monitoring (ECAM) and/or multipurpose control display unit (MCDU),
--Transient disconnection of several systems (auto pilot, yaw 
damper, auto throttle), triggering of aircraft system warnings and/
or flags,
--Loss of IDG power supply on the affected engine, and/or
--Flickering of cabin lights.
    The Aircraft Flight Manual (AFM) Temporary Revision (TR) 
4.02.00/20 was issued as a procedure to be applied in such case. 
Consequently, EASA AD 2006-0280, which superseded the DGAC France AD 
F-2004-074 [which corresponds to FAA AD 2004-15-14, Amendment 39-
13748 (69 FR 45243, July 29, 2004)], required the amendment of the 
AFM to impose the limitations as detailed in AFM TR 4.02.00/20 for 
aeroplanes with certain engines (limited batch of engines, 
identified by serial number) installed.
    After the introduction of this AFM TR, some operators reported 
cases of Display Unit (DU) flickering, despite the fact that the 
engines installed did not belong to the affected batch, and that 
these aeroplanes had been modified to incorporate one of the two 
terminating actions, Airbus Service Bulletin (SB) A320-71-1030 
(Airbus modification (mod.) 34982) and SB A320-71-1034 (Airbus mod. 
32943). The investigations of these occurrences revealed some 
intermittent electrical power supply interruptions. Analysis showed 
that these interruptions may fluctuate within the electrical 
protection limits and in some rare occasions, may affect some of the 
connected aeroplanes systems.
    As a consequence, some intermittent electrical power supply 
interruptions may not be detectable by the electrical power 
monitoring system, thereby preventing an automatic disconnection of 
the failed generator.
    To address this issue, Airbus has issued a new AFM procedure, 
applicable to all aeroplanes. This ``DISPLAY UNIT FAILURE'' 
procedure, which replaces the one contained in AFM TR 4.02.00/20, 
allows the flight crew to determine the affected generator, select 
it OFF and reset the rudder trim.
    For the reasons described above, this AD, which supersedes EASA 
AD 2006-0280, requires amendment of the applicable AFM to ensure 
that the flight crew applies the appropriate operational procedure.

The unsafe condition is transient loss of certain systems, which could 
result in the reduced ability of the flightcrew to cope with adverse 
flight conditions. This AD also expands the applicability of AD 2004-
15-14, Amendment 39-13748 (69 FR 45243, July 29, 2004), by including 
all Model A318, A319, A320, and A321 series airplanes. You may obtain 
further information by examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Temporary Revision TR112, Issue 1.1, dated 
November 29, 2010, to the Airbus A318/A319/A320/A321 Airplane Flight 
Manual. The actions described in this service information are intended 
to correct the unsafe condition identified in the MCAI.

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.

Differences Between the AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the AD.

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 of 
the additional in-service events of DU flickering on Model A318, A319, 
A320, and A321 series airplanes that were not included in the 
applicability of FAA AD 2004-15-14, Amendment 39-13748 (69 FR 45243, 
July 29, 2004), or on which the terminating actions of paragraph (h) of 
that AD were done. 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-2011-0917; Directorate 
Identifier 2011-NM-157-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
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 https://www.regulations.gov, including any personal information you provide. We

[[Page 56281]]

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); and
    3. 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.

Post-IDG Shutdown Inspection

    (k) For all airplanes: If an IDG is shut down by the flightcrew 
in accordance with the TR procedures specified in paragraph (j) of 
this AD, or if an IDG is shut down automatically on or after the 
effective date of this AD, do the actions specified in paragraph 
(k)(1) or (k)(2) of this AD.
    (1) Before further flight, inspect the firewall connector of the 
affected IDG to detect signs of arcing, in accordance with a method 
approved by the Manager, International Branch, ANM-116, Transport 
Airplane Directorate, FAA. If any sign of arcing is detected: Before 
further flight, either repair the connector or replace the connector 
with a new connector, in accordance with a method approved by the 
Manager, International Branch, ANM-116.
    (2) Operate the airplane with the affected IDG inoperative in

FAA AD Differences

    Note 5: This AD differs from the MCAI and/or service information 
as follows: The MCAI does not require inspecting an IDG that has 
been shut down in accordance with Airbus TR TR112, Issue 1.1, dated 
November 29, 2010, or that has been shut down automatically. We have 
determined that investigative and corrective actions (including an 
inspection for signs of arcing, and repair or replacement of any 
discrepant IDG harness/connector with a new harness/connector) are 
necessary due to the severity of the problem to prevent the unsafe 
condition from recurring. The inspections and corrective actions 
must be done in accordance with a method approved by Manager, 
International Branch, ANM-116.

Other FAA AD Provisions

    (l) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, has the authority to approve AMOCs 
for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as 
appropriate. If sending information directly to the International 
Branch, send it to ATTN: Sanjay Ralhan, Aerospace Engineer, 
International Branch, ANM-116, Transport Airplane Directorate, FAA,

227-1405; fax (425) 227-1149 Information may be e-mailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. Before using any approved AMOC, notify 
your appropriate principal inspector, or lacking a principal 
inspector, the manager of the local flight standards district 
office/certificate holding district office. The AMOC approval letter 
must specifically reference this AD. AMOCs approved previously for 
AD 2004-15-14, Amendment 39-13748 (69 FR 45243, July 29, 2004), are 
acceptable for corresponding provisions of this AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
