ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A330–200, A330–300, A340–200, and A340–300 series airplanes; and Model A340–541 and –642 airplanes. The existing AD currently requires repetitively resetting the display units (DUs) for the electronic instrument system (EIS), either by switching them off and back on again or by performing a complete electrical shutdown of the airplane. This proposed AD would require installing new software, which would end the actions required by the existing AD. This proposed AD also would add additional airplanes that may be placed on the U.S. Register in the future. This proposed AD results from an incident in which all of the DUs for the EIS went blank simultaneously during flight. We are proposing this AD to prevent automatic reset of the DUs for the EIS during flight and consequent loss of data from the DUs, which could reduce the ability of the flightcrew to control the airplane during adverse flight conditions. We must receive comments on this proposed AD by April 16, 2007.

Discussion On August 18, 2005, we issued AD 2005–17–18, amendment 39–14239 (70 FR 50166, August 26, 2005), for certain Airbus Model A330–200, A330–300, A340–200, and A340–300 series airplanes; and Model A340–541 and –642 airplanes. That AD requires repetitively resetting the display units (DUs) for the electronic instrument system (EIS), either by switching them off and back on again or by performing a complete electrical shutdown of the airplane. That AD resulted from an incident in which all of the DUs for the EIS went blank simultaneously during flight. We issued that AD to prevent automatic reset of the DUs for the EIS during flight and consequent loss of data from the DUs, which could reduce the ability of the flightcrew to control the airplane during adverse flight conditions. Actions Since Existing AD Was Issued After the issuance of AD 2005–17–18, ´ ´ the Direction Generale de l’Aviation Civile (DGAC), which is the airworthiness authority for France, issued French emergency airworthiness directive UF–2005–166, dated September 23, 2005, which was superseded by F–2005–166 R1, dated October 26, 2005. Those French airworthiness directives cancelled French airworthiness directive UF– 2005–150, dated August 10, 2005 (referred to in AD 2005–17–18), and required that the resets be done only by the aircraft flightcrew in accordance with Airbus A330 Airplane Flight Manual (AFM) Temporary Revision (TR) 4.03.00/26 and A340 AFM TR 4.03.00/ 37, both dated October 11, 2005; as applicable. We determined at that time that further rulemaking was not necessary, because AD 2005–17–18 adequately addresses the unsafe condition by requiring the resets to be done either by certificated maintenance personnel or by the flightcrew. In addition, we approved TRs 4.03.00/26 and 4.03.00/37 as alternative methods of compliance (AMOC) to the requirements of paragraph (f) of AD 2005–17–18 (addressed in paragraph (j)(3) of this proposed AD). In the preamble to AD 2005–17–18, we specified that the actions required by that AD were considered ‘‘interim action’’ and that the manufacturer was developing a modification to address the unsafe condition. We indicated that we may consider further rulemaking once the modification was developed, approved, and available. The manufacturer now has developed such a modification, and we now have determined that further rulemaking action is indeed necessary; this proposed AD follows from that determination.

FAA’s Determination and Requirements of the Proposed AD Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, mandated the service information and issued EASA airworthiness directive 2006–0196, VerDate Aug<31>2005 14:19 Mar 14, 2007 Jkt 211001 PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness E:\FR\FM\15MRP1.SGM 15MRP1 12129 Federal Register / Vol. 72, No. 50 / Thursday, March 15, 2007 / Proposed Rules agreement. Pursuant to this bilateral airworthiness agreement, the EASA has kept the FAA informed of the situation described above. We have examined the EASA’s findings, evaluated all pertinent information, and determined that AD action is necessary for airplanes of this type design that are certificated for operation in the United States. This proposed AD would supersede AD 2005–17–18 and would retain the requirements of the existing AD. This proposed AD would also require accomplishing the actions specified in service bulletins described previously, which would end the repetitive actions required by AD 2005–17–18. This proposed AD also would add additional airplanes that are subject to the identified unsafe condition of this proposed AD and that may be placed on the U.S. Register in the future. Difference Between the EASA Airworthiness Directive and This Proposed AD The applicability of EASA airworthiness directive 2006–0196 excludes certain airplanes on which Airbus Service Bulletin A330–31–3087, A340–31–4100, or A340–31–5021 has been done in service. However, we have not excluded those airplanes in the applicability of this proposed AD; rather, this proposed AD includes a requirement to accomplish the actions specified in the original issue of those service bulletins. This requirement would ensure that the actions specified in the service bulletins and required by this proposed AD are accomplished on all affected airplanes. Operators must continue to operate the airplane in the configuration required by this proposed AD unless an AMOC is approved. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this proposed AD. The average labor rate per hour is $80.

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. 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 the proposed regulation: 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 proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. Regulatory Findings We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the Air transportation, Aircraft, Aviation safety, Safety.

Models AT–602, AT–802, and AT– 802A Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). rmajette on PROD1PC67 with PROPOSALS AGENCY: SUMMARY: We propose to supersede Airworthiness Directive (AD) 2006–22– 08, which applies to all Air Tractor, Inc. (Air Tractor) Models AT–602, AT–802, and AT–802A airplanes. AD 2006–22– 08 currently requires you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. Since we issued AD 2006–22– 08, the FAA has received reports of two Model AT–802A airplanes with cracked engine mounts (at 2,815 hours time-inservice (TIS) and 1,900 hours TIS) below the initial compliance time in AD 2006–22–08. The FAA has determined that an initial inspection at 1,300 hours TIS is required instead of 4,000 hours TIS required by AD 2006–22–08. Consequently, this proposed AD would retain the actions of AD 2006–22–08 while requiring the initial inspection at 1,300 hours TIS. We are proposing this AD to detect and correct cracks in the engine mount, which could result in failure of the engine mount. Such failure could lead to separation of the engine from the airplane.

AD 2006–22– 08 currently requires the following on all Air Tractor Models AT–602, AT–802, and AT–802A airplanes: PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 12131 • Inspect (initially and repetitively) the engine mount for any cracks; • Repair or replace any cracked engine mount; and • Report any cracks found to the FAA. Since we issued AD 2006–22–08, the FAA has received reports of two Model AT–802A airplanes with cracked engine mounts (at 2,815 hours TIS and 1,900 hours TIS) below the initial compliance time in AD 2006–22–08. The FAA has determined that an initial inspection at 1,300 hours TIS is required instead of 4,000 hours TIS as required by AD 2006–22–08. This condition, if not corrected, could result in failure of the engine mount. Such failure could lead to separation of the engine from the airplane. Relevant Service Information We have reviewed Snow Engineering Co. Service Letter #253, dated December 12, 2005, revised January 22, 2007. The service information describes procedures for performing a visual inspection for cracks of the engine mount and requesting a repair scheme from the manufacturer. Snow Engineering Co. has a licensing agreement with Air Tractor that allows them to produce technical data to use for Air Tractor products. FAA’s Determination and Requirements of the Proposed AD We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would supersede AD 2006–22–08 with a new AD that would require you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. To repair a cracked engine mount, you would obtain an FAA-approved repair scheme from Air Tractor following the instructions in the service information. This proposed AD would require you to use the service information described previously to perform these actions. Costs of Compliance We estimate that this AD affects 368 airplanes in the U.S. registry. We estimate the following costs to do each required inspection: E:\FR\FM\15MRP1.SGM 15MRP1

Airworthiness Directives; Airbus Model A330 and A340-200 
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede an existing airworthiness 
directive (AD) that applies to certain Airbus Model A330-200, A330-300, 
A340-200, and A340-300 series airplanes; and Model A340-541 and -642 
airplanes. The existing AD currently requires repetitively resetting 
the display units (DUs) for the electronic instrument system (EIS), 
either by switching them off and back on again or by performing a 
complete electrical shutdown of the airplane. This proposed AD would 
require installing new software, which would end the actions required 
by the existing AD. This proposed AD also would add additional 
airplanes that may be placed on the U.S. Register in the future. This 
proposed AD results from an incident in which all of the DUs for the 
EIS went blank simultaneously during flight. We are proposing this AD 
to prevent automatic reset of the DUs for the EIS during flight and 
consequent loss of data from the DUs, which could reduce the ability of 
the flightcrew to control the airplane during adverse flight 
conditions.

DATES: We must receive comments on this proposed AD by April 16, 2007.

Discussion

    On August 18, 2005, we issued AD 2005-17-18, amendment 39-14239 (70 
FR 50166, August 26, 2005), for certain Airbus Model A330-200, A330-
300, A340-200, and A340-300 series airplanes; and Model A340-541 and -
642 airplanes. That AD requires repetitively resetting the display 
units (DUs) for the electronic instrument system (EIS), either by 
switching them off and back on again or by performing a complete 
electrical shutdown of the airplane. That AD resulted from an incident 
in which all of the DUs for the EIS went blank simultaneously during 
flight. We issued that AD to prevent automatic reset of the DUs for the 
EIS during flight and consequent loss of data from the DUs, which could 
reduce the ability of the flightcrew to control the airplane during 
adverse flight conditions.

Actions Since Existing AD Was Issued

    After the issuance of AD 2005-17-18, the Direction 
G[eacute]n[eacute]rale de l'Aviation Civile (DGAC), which is the 
airworthiness authority for France, issued French emergency 
airworthiness directive UF-2005-166, dated September 23, 2005, which 
was superseded by F-2005-166 R1, dated October 26, 2005. Those French 
airworthiness directives cancelled French airworthiness directive UF-
2005-150, dated August 10, 2005 (referred to in AD 2005-17-18), and 
required that the resets be done only by the aircraft flightcrew in 
accordance with Airbus A330 Airplane Flight Manual (AFM) Temporary 
Revision (TR) 4.03.00/26 and A340 AFM TR 4.03.00/37, both dated October 
11, 2005; as applicable. We determined at that time that further 
rulemaking was not necessary, because AD 2005-17-18 adequately 
addresses the unsafe condition by requiring the resets to be done 
either by certificated maintenance personnel or by the flightcrew. In 
addition, we approved TRs 4.03.00/26 and 4.03.00/37 as alternative 
methods of compliance (AMOC) to the requirements of paragraph (f) of AD 
2005-17-18 (addressed in paragraph (j)(3) of this proposed AD).
    In the preamble to AD 2005-17-18, we specified that the actions 
required by that AD were considered ``interim action'' and that the 
manufacturer was developing a modification to address the unsafe 
condition. We indicated that we may consider further rulemaking once 
the modification was developed, approved, and available. The 
manufacturer now has developed such a modification, and we now have 
determined that further rulemaking action is indeed necessary; this 
proposed AD follows from that determination.

Relevant Service Information

    Airbus has issued the primary service bulletins in the following 
table:

    These primary service bulletins describe procedures for installing 
electronic instrument system 2 (EIS2) software standard L6-1, which 
would end the actions required by AD 2005-17-18.

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

    Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition. The European 
Aviation Safety Agency (EASA), which is the Technical Agent for the 
Member States of the European Union, mandated the service information 
and issued EASA airworthiness directive 2006-0196, dated July 10, 2006 
(which cancels French airworthiness directive F-2005-166 R1), to ensure 
the continued airworthiness of these airplanes in the European Union.

FAA's Determination and Requirements of the Proposed AD

    These airplane models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness

[[Page 12129]]

agreement. Pursuant to this bilateral airworthiness agreement, the EASA 
has kept the FAA informed of the situation described above. We have 
examined the EASA's findings, evaluated all pertinent information, and 
determined that AD action is necessary for airplanes of this type 
design that are certificated for operation in the United States.
    This proposed AD would supersede AD 2005-17-18 and would retain the 
requirements of the existing AD. This proposed AD would also require 
accomplishing the actions specified in service bulletins described 
previously, which would end the repetitive actions required by AD 2005-
17-18. This proposed AD also would add additional airplanes that are 
subject to the identified unsafe condition of this proposed AD and that 
may be placed on the U.S. Register in the future.

Difference Between the EASA Airworthiness Directive and This Proposed 
AD

    The applicability of EASA airworthiness directive 2006-0196 
excludes certain airplanes on which Airbus Service Bulletin A330-31-
3087, A340-31-4100, or A340-31-5021 has been done in service. However, 
we have not excluded those airplanes in the applicability of this 
proposed AD; rather, this proposed AD includes a requirement to 
accomplish the actions specified in the original issue of those service 
bulletins. This requirement would ensure that the actions specified in 
the service bulletins and required by this proposed AD are accomplished 
on all affected airplanes. Operators must continue to operate the 
airplane in the configuration required by this proposed AD unless an 
AMOC is approved.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this proposed AD. The average labor rate per hour is 
$80.

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

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 have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    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 proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.

Unsafe Condition

    (d) This AD results from an incident in which all of the display 
units (DUs) for the EIS went blank simultaneously during flight. We 
are issuing this AD to prevent automatic reset of the DUs for the 
EIS during flight and consequent loss of data from the DUs, which 
could reduce the ability of the flightcrew to control the airplane 
during adverse flight conditions.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.
