SUPPLEMENTARY INFORMATION: During approach, a Falcon 2000EX operator experienced a temporary loss of the 4 Electronic Flight Instrumentation System (EFIS) display units followed by a consecutive restart of the avionics. During initial investigation, a loose connection on the DC load distribution system was discovered and determined to be the root cause of this event. However, further analysis pointed out that large electrical transients on the essential bus bar may possibly cause simultaneous and temporary power shortage on both sides of the electrical system. This Airworthiness Directive (AD) requires a wiring modification of the GCUs (Generator Control Units) to increase the electrical system robustness. This action is necessary to prevent a momentary loss of data on the EFIS screens, which could lead to the pilot’s loss of situational awareness during initial climb or approach/landing, and possibly result in reduced control of the airplane. This action is intended to address the identified unsafe condition. You may obtain further information by examining the MCAI in the AD docket.

Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2008–0557; Directorate Identifier 2007–NM–364–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD based on those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2007–0290, dated November 26, 2007 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Relevant Service Information Dassault has issued Service Bulletin F2000EX–141, Revision 1, dated November 26, 2007. 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 Proposed 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 proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between This 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 E:\FR\FM\20MYP1.SGM 20MYP1 29092 Federal Register / Vol. 73, No. 98 / Tuesday, May 20, 2008 / Proposed Rules 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 proposed 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 proposed AD. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect 57 products of U.S. registry. We also estimate that it would take 8 workhours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per workhour. Required parts would cost about $0 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $36,480, or $640 per product. hsrobinson on PROD1PC76 with PROPOSALS-1 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 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 VerDate Aug<31>2005 17:03 May 19, 2008 Jkt 214001 responsibilities among the various levels of government. For the reasons discussed above, I certify this 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.

FOR FURTHER INFORMATION CONTACT: Kerry Kehoe, Federal Consistency Specialist, 301–713–3155 ext. 151, Office of Ocean and Coastal Resource Management, NOAA. SUPPLEMENTARY INFORMATION: I. Background The CZMA (16 U.S.C. 1451–1465) was enacted on October 27, 1972, to encourage coastal States, Great Lake States, and United States Territories and Commonwealths (collectively referred to as ‘‘coastal States’’ or ‘‘States’’) to be proactive in managing the uses and resources of the coastal zone for their benefit and the benefit of the Nation. The CZMA recognizes a national interest in the uses and resources of the coastal zone and in the importance of balancing the competing uses of coastal resources. The CZMA is a voluntary program for States. If a State elects to participate it must develop and implement a coastal management program (CMP) pursuant to federal requirements. See CZMA section 306(d)(16 U.S.C. 1455(d)); 15 CFR part 923. State CMPs are comprehensive management plans that describe the uses subject to the management program, the authorities and enforceable policies of the management program, the boundaries of the State’s coastal zone, the organization of the management program, and related State coastal management concerns. Thirtyfive coastal States are eligible to participate in the federal coastal management program. Thirty-four of the eligible States have federally approved CMPs. An important component of the CZMA program is that State CMPs are developed with the full participation of state and local agencies, industry, the public, other interested groups and Federal agencies. See e.g., 16 U.S.C. 145 1(i) and (m), 1452(2)(H) and (I), 1452(4) and (5), 1455(d)(1) and (3)(B), and 1456. Program changes are changes to NOAAapproved components of State CZMA programs and new program components. There are five program approval areas (includes related changes to, or new, enforceable policies related to the five areas). The five areas are: 1. Uses subject to program; 2. Coastal zone boundaries; 3. National interest; 4. Special Area Management Plans; and 5. Authorities & Organization. Program changes are important for several reasons. The statute requires PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 29093 submission to NOAA and NOAA approval (16 U.S.C. 1455(e)); state programs are not static; laws and issues change requiring continual operation of the CZMA State-Federal partnership. The State-Federal partnership is a cornerstone of the CZMA. The primacy of state CZMA decisions and the CZMA federal consistency requirement is balanced with adequate consideration national interest components, Federal agency input into the content of State programs, and NOAA approval. In their federally approved CMPs and state CZMA decisions states must consider national interest areas of the CZMA to benefit national, not just local interests. In addition to the national interest in comprehensive coastal management by states, states must give priority consideration to coastal dependant national interest activities: Defense, energy, ports, transportation. For example, some of the more important issues NOAA must consider when evaluating program changes include whether the proposed change would: Affect CZMA national interest areas; seek to regulate federal agencies or areas outside state jurisdiction; be preempted by federal law; discriminate against particular coastal users or federal agencies; be enforceable under State law; raise issues under the National Environmental Policy Act (NEPA), Endangered Species Act (ESA), National Historic Preservation Act (NHPA), etc. Program changes are also important because the CZMA has a strong public participation role, combined with the State-Federal partnership. NOAA can only approve CMPs and changes to CMPs after Federal agencies and the public have an opportunity to comment on whether proposed new or revised ‘‘enforceable policies’’ are appropriate under the CZMA authority and other federal and state legal requirements. An enforceable policy is a State policy that is legally binding under State law (e.g., through constitutional provisions, laws, regulations, land use plans, ordinances, or judicial or administrative decisions) and by which a State exerts control over private and public coastal uses and resources, and which are incorporated in a State’s federally approved CMP. See 16 U.S.C. 1453(6a). This means that enforceable policies must be given legal effect by State law and cannot apply to Federal lands, Federal waters, Federal agencies or other areas or entities outside a State’s jurisdiction, unless authorized by Federal law. Also, the CZMA section 307 federal consistency provision requires that state enforceable policies are the standards that apply to Federal agency activities, federal license E:\FR\FM\20MYP1.SGM 20MYP1

Airworthiness Directives; Dassault Model Falcon 2000EX Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed 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:

    During approach, a Falcon 2000EX operator experienced a 
temporary loss of the 4 Electronic Flight Instrumentation System 
(EFIS) display units followed by a consecutive restart of the 
avionics. During initial investigation, a loose connection on the DC 
load distribution system was discovered and determined to be the 
root cause of this event. However, further analysis pointed out that 
large electrical transients on the essential bus bar may possibly 
cause simultaneous and temporary power shortage on both sides of the 
electrical system.
    This Airworthiness Directive (AD) * * * action is necessary to 
prevent a momentary loss of data on the EFIS screens, which could 
lead to the pilot's loss of situational awareness during initial 
climb or approach/landing, and possibly result in reduced control of 
the airplane. * * *

The proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2007-0290, dated November 26, 2007 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    During approach, a Falcon 2000EX operator experienced a 
temporary loss of the 4 Electronic Flight Instrumentation System 
(EFIS) display units followed by a consecutive restart of the 
avionics. During initial investigation, a loose connection on the DC 
load distribution system was discovered and determined to be the 
root cause of this event. However, further analysis pointed out that 
large electrical transients on the essential bus bar may possibly 
cause simultaneous and temporary power shortage on both sides of the 
electrical system.
    This Airworthiness Directive (AD) requires a wiring modification 
of the GCUs (Generator Control Units) to increase the electrical 
system robustness. This action is necessary to prevent a momentary 
loss of data on the EFIS screens, which could lead to the pilot's 
loss of situational awareness during initial climb or approach/
landing, and possibly result in reduced control of the airplane. 
This action is intended to address the identified unsafe condition.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Dassault has issued Service Bulletin F2000EX-141, Revision 1, dated 
November 26, 2007. 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 Proposed 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 proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between This 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

[[Page 29092]]

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 proposed 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 proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect 57 products of U.S. registry. We also estimate that it 
would take 8 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Required parts would cost about $0 per product. Where the 
service information lists required parts costs that are covered under 
warranty, we have assumed that there will be no charge for these costs. 
As we do not control warranty coverage for affected parties, some 
parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be $36,480, or $640 per product.

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 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 this 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.

2007-NM-364-AD.

Comments Due Date

    (a) We must receive comments by June 19, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Dassault Model Falcon 2000EX airplanes 
from serial number 1 to 107 inclusive, certificated in any category; 
which have not been modified by Dassault Service Bulletin (SB) 
F2000EX-141.

Subject

    (d) Air Transport Association (ATA) of America Code 24: 
Electrical Power

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states: During approach, a Falcon 2000EX operator experienced a 
temporary loss of the 4 Electronic Flight Instrumentation System 
(EFIS) display units followed by a consecutive restart of the 
avionics. During initial investigation, a loose connection on the DC 
load distribution system was discovered and determined to be the 
root cause of this event. However, further analysis pointed out that 
large electrical transients on the essential bus bar may possibly 
cause simultaneous and temporary power shortage on both sides of the 
electrical system.
    This Airworthiness Directive (AD) requires a wiring modification 
of the GCUs (Generator Control Units) to increase the electrical 
system robustness. This action is necessary to prevent a momentary 
loss of data on the EFIS screens, which could lead to the pilot's 
loss of situational awareness during initial climb or approach/
landing, and possibly result in reduced control of the airplane. 
This action is intended to address the identified unsafe condition.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) Within 13 months after the effective date of this AD, modify 
the GCU electrical wiring as instructed in the Accomplishment 
Instructions of Dassault Service Bulletin F2000EX-141, Revision 1, 
dated November 26, 2007.
    (2) Actions done prior to the effective date of this AD 
according to Dassault Service Bulletin F2000EX-141, dated February 
16, 2007, are acceptable for compliance with the corresponding 
requirements of this AD.

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows: No differences.

Other FAA AD Provisions

    (g) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
has the authority to approve AMOCs for this AD, if requested using

applies, notify your appropriate principal inspector (PI) in the FAA 
Flight Standards District Office (FSDO), or lacking a PI, your local 
FSDO.
    (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.
    (3) Reporting Requirements: For any reporting requirement in
