ACTION: Notice of proposed rulemaking (NPRM). AGENCY: VerDate Aug<31>2005 15:27 Oct 18, 2007 Jkt 214001 SUMMARY: We propose to adopt a new airworthiness directive (AD) for Eurocopter France Model EC130B4 helicopters. 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 aviation authority of France, with which we have a bilateral agreement, states in the MCAI: This Airworthiness Directive (AD) is issued following the discovery of several cases of loosened rivets in the tube-to-flange attachment of the tail rotor drive center section shaft. In one case, this loosening of rivets was associated with a crack in the tube which started from a loosened-rivet hole. These occurrences can lead to failure of the tail rotor drive center section shaft. The proposed AD would require actions that are intended to address the unsafe condition caused by cracks and loosened rivets in the tube-to-flange attachment of the tail rotor and the unsafe condition caused by the out-ofperpendicularity of the No. 1 bearing. DATES: We must receive comments on this proposed AD by November 19, 2007. You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments. • Fax: 202–493–2251. • Mail: U.S. Department of Transportation, Docket Operations, M– 30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC 20590. • Hand Delivery: U.S. Department of Transportation, Docket Operations, M– 30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC 20590, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. ADDRESSES: Examining the AD Docket You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this proposed AD, the economic evaluation, any comments received, and other information.

SUPPLEMENTARY INFORMATION: Streamlined Issuance of AD The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. This streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products. This proposed AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The proposed AD contains text copied from the MCAI and for this reason might not follow our plain language principles. Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2007–0056; Directorate Identifier 2007–SW–06–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 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 proposed AD. Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued an MCAI in the form of EASA Airworthiness Directive No. F–2005–190, dated November 23, 2005 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for this French-certificated product. The MCAI states: This Airworthiness Directive (AD) is issued following the discovery of several cases of loosened rivets in the tube-to-flange E:\FR\FM\19OCP1.SGM 19OCP1 59230 Federal Register / Vol. 72, No. 202 / Friday, October 19, 2007 / Proposed Rules attachment of the tail rotor drive center section shaft. In one case, this loosening of rivets was associated with a crack in the tube which started from a loosened-rivet hole. These occurrences can lead to failure of the tail rotor drive center section shaft. You may obtain further information by examining the MCAI and service information in the AD docket. Relevant Service Information Eurocopter has issued Alert Service Bulletin No. 65A002, dated November 16, 2005. The actions described in the MCAI are intended to correct the same unsafe condition as that identified in the service information. FAA’s Determination and Proposed Requirements This product has been approved by the aviation authority of France, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, we have been notified of the unsafe condition described in the MCAI and the service information. 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 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 the ‘‘FAA Differences’’ section in the proposed AD. rmajette on PROD1PC64 with PROPOSALS Costs of Compliance We estimate that this proposed AD would affect 68 helicopters of U.S. registry and that it would take about 1 work-hour per helicopter to determine if there are any cracks or loosened rivets in the tube-to-flange attachment of the tail rotor drive center section shaft and to determine if the No. 1 bearing is outof-perpendicularity. Also, we estimate that it would take about 4 work-hours per helicopter to remove and replace any nonconforming parts. The average labor rate is $80 per work-hour. VerDate Aug<31>2005 15:27 Oct 18, 2007 Jkt 214001 Required parts would cost about $15,007 per helicopter if replacing a tail rotor drive center section shaft is necessary. Based on these figures, we estimate the cost to inspect the fleet of helicopters to be $5,440. Assuming 3 helicopters are found to have nonconforming parts, we estimate the costs to replace these parts to be $45,981, resulting in the total cost of the proposed AD on U.S. operators to be $51,421. 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 an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION: Background BIS administers a system of export and reexport controls in accordance with the Export Administration Regulations (EAR). In doing so, BIS requires that parties wishing to engage in certain transactions apply for licenses, submit encryption review requests, or submit certain notifications to BIS. BIS also reviews, upon request, specifications of various items and determines their proper classification under the EAR. Currently members of the public submit these applications, requests and notifications to BIS in one of three ways: via SNAP–R, via BIS’s Electronic License Application Information Network (ELAIN), or via the paper BIS Multipurpose Application Form BIS 748–P and its two appendices, the BIS 748–P A (item appendix) and the BIS 748–P B (end user appendix). In PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 59231 many instances, BIS needs additional documents to act on the submission. For documents that relate to paper submissions, the documents can be mailed or delivered to BIS with the BIS 748–P form. For submissions made electronically via ELAIN, the documents must be sent to BIS separately and matched up with the application when they arrive. In 2006, BIS made a number of improvements its then existing Simplified Network Application Processing system (SNAP), and designated this improved version as ‘‘SNAP–R’’. The improvements include the ability to include documents related to a submission in the form of PDF (portable document format) files as ‘‘attachments’’ to the submission. Other improvements include a feature that allows BIS personnel to request additional information from the submitting party and for the party to submit that information in a manner that ties the chain of communication to the submission. BIS believes that use of SNAP–R will reduce processing times and simplify compliance with and administration of export controls. SNAP–R provides not only improved efficiency in submission and processing, but improved end-user security through rights management and an updated application and security infrastructure. Therefore, BIS proposes to require that all export and reexport license applications (other than Special Comprehensive License applications), classification requests, encryption review requests, License Exception AGR notifications, and ‘‘attached’’ related documents be submitted to BIS via its Simplified Network Application Process (SNAP–R) system unless BIS authorizes paper submissions. This proposed rule would also set the criteria by which BIS would authorize paper submissions and would terminate use of ELAIN. This proposed rule would make no changes to the procedures by which the public requests advisory opinions because such requests are not processed via either the paper form 748–P or either of BIS’s existing electronic systems. Changes Proposed To Be Made by This Rule The changes that this proposed rule would make center on part 748 of the EAR, which sets forth the principal procedures governing the submission of the applications, review requests and notifications that would be affected by this proposed rule. The changes would appear in § 748.1—‘‘General provisions,’’ § 748.3—‘‘Classification requests, advisory opinions, and E:\FR\FM\19OCP1.SGM 19OCP1

Airworthiness Directives; Eurocopter France Model EC130 B4 
Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Eurocopter France Model EC130B4 helicopters. 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 aviation authority of 
France, with which we have a bilateral agreement, states in the MCAI:

    This Airworthiness Directive (AD) is issued following the 
discovery of several cases of loosened rivets in the tube-to-flange 
attachment of the tail rotor drive center section shaft.
    In one case, this loosening of rivets was associated with a 
crack in the tube which started from a loosened-rivet hole.
    These occurrences can lead to failure of the tail rotor drive 
center section shaft.

    The proposed AD would require actions that are intended to address 
the unsafe condition caused by cracks and loosened rivets in the tube-
to-flange attachment of the tail rotor and the unsafe condition caused 
by the out-of-perpendicularity of the No. 1 bearing.

DATES: We must receive comments on this proposed AD by November 19, 
2007.

ADDRESSES: You may send comments by any of the following methods:

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance 
of ADs related to MCAI. This streamlined process will allow us to adopt 
MCAI safety requirements in a more efficient manner and will reduce 
safety risks to the public. This process continues to follow all FAA AD 
issuance processes to meet legal, economic, Administrative Procedure 
Act, and Federal Register requirements. We also continue to meet our 
technical decision-making responsibilities to identify and correct 
unsafe conditions on U.S.-certificated products.
    This proposed AD references the MCAI and related service 
information that we considered in forming the engineering basis to 
correct the unsafe condition. The proposed AD contains text copied from 
the MCAI and for this reason might not follow our plain language 
principles.

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2007-0056; 
Directorate Identifier 2007-SW-06-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 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 proposed AD.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued an 
MCAI in the form of EASA Airworthiness Directive No. F-2005-190, dated 
November 23, 2005 (referred to after this as ``the MCAI''), to correct 
an unsafe condition for this French-certificated product. The MCAI 
states:

    This Airworthiness Directive (AD) is issued following the 
discovery of several cases of loosened rivets in the tube-to-flange

[[Page 59230]]

attachment of the tail rotor drive center section shaft.
    In one case, this loosening of rivets was associated with a 
crack in the tube which started from a loosened-rivet hole.
    These occurrences can lead to failure of the tail rotor drive 
center section shaft.

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

Relevant Service Information

    Eurocopter has issued Alert Service Bulletin No. 65A002, dated 
November 16, 2005. The actions described in the MCAI are intended to 
correct the same unsafe condition as that identified in the service 
information.

FAA's Determination and Proposed Requirements

    This product has been approved by the aviation authority of France, 
and is approved for operation in the United States. Pursuant to our 
bilateral agreement with this State of Design Authority, we have been 
notified of the unsafe condition described in the MCAI and the service 
information. 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 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 the ``FAA Differences'' section in the proposed AD.

Costs of Compliance

    We estimate that this proposed AD would affect 68 helicopters of 
U.S. registry and that it would take about 1 work-hour per helicopter 
to determine if there are any cracks or loosened rivets in the tube-to-
flange attachment of the tail rotor drive center section shaft and to 
determine if the No. 1 bearing is out-of-perpendicularity. Also, we 
estimate that it would take about 4 work-hours per helicopter to remove 
and replace any nonconforming parts. The average labor rate is $80 per 
work-hour. Required parts would cost about $15,007 per helicopter if 
replacing a tail rotor drive center section shaft is necessary. Based 
on these figures, we estimate the cost to inspect the fleet of 
helicopters to be $5,440. Assuming 3 helicopters are found to have 
nonconforming parts, we estimate the costs to replace these parts to be 
$45,981, resulting in the total cost of the proposed AD on U.S. 
operators to be $51,421.

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 an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Eurocopter France: Docket No. FAA-2007-0056; Directorate Identifier 
2007-SW-06-AD.

Comments Due Date

    (a) We must receive comments by November 19, 2007.

Other Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model EC130 B4 helicopters, with a tail 
rotor drive center section shaft, part number (P/N) 350A340202; and 
bearing, P/N 593404, certificated in any category.

Reason

    (d) The mandatory continuing airworthiness information (MCAI) 
states:
    This Airworthiness Directive (AD) is issued following the 
discovery of several cases of loosened rivets in the tube-to-flange 
attachment of the tail rotor drive center section shaft.
    In one case, this loosening of rivets was associated with a 
crack in the tube which started from a loosened-rivet hole.
    These occurrences can lead to failure of the tail rotor drive 
center section shaft.

Actions and Compliance

    (e) Within 50 hours time-in-service (TIS) or 3 months, whichever 
occurs first, unless already done, do the following actions.
    (1) Inspect for cracks or loosened rivets in the tube-to-flange 
attachment of the tail rotor drive center section shaft and inspect 
the perpendicularity of bearing No. 1 in compliance with the 
Accomplishment Instructions, paragraph 2.B.2., of Eurocopter Alert 
Service Bulletin No. 65A002, dated November 16, 2005 (ASB).
    (2) If a crack or loosened rivet is found, replace the tail 
rotor drive center section shaft before further flight.
    (3) If the out-of perpendicularity of the bearing is more than 
0.1 mm, apply the corrective procedure described in the 
Accomplishment Instructions, paragraph 2.B.2., of the ASB.

Differences Between the FAA AD and the MCAI

    (f) None.
