ACTION: Final rule; request for comments. SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. 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: Identification of an unsafe condition related to the loss of the fail-safe design criteria for the rudder trim, pitch trim and stick pusher control functions after a reported event led in April 2008 to the release of AD 2008–0062 to mandate the ATR modification No. 05780. It has appeared that some airplanes manufactured and delivered before April 1, 2008, may have received on the productionline a partial or incorrect implementation of the required ATR mod. No. 05780. * * * * * The unsafe condition is loss of the rudder trim, pitch trim, and stick pusher control, which could result in loss of control of the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI. DATES: This AD becomes effective June 29, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications, listed in the AD as of June 29, 2009. We must receive comments on this AD by July 13, 2009.

SUPPLEMENTARY INFORMATION: 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 2008–0218, dated December 10, 2008 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: 27911 bundles, and re-installing them if necessary. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Avions de Transport Regional has issued Service Bulletins ATR42–92– 0020 and ATR72–92–1021, both dated October 17, 2008. 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. There are no products of this type currently registered in the United States. However, this rule is necessary to ensure that the described unsafe condition is addressed if any of these products are placed on the U.S. Register in the future. Differences Between the AD and the MCAI or Service Information Identification of an unsafe condition related to the loss of the fail-safe design criteria for the rudder trim, pitch trim and stick pusher control functions after a reported event led in April 2008 to the release of AD 2008–0062 to mandate the ATR modification No. 05780. It has appeared that some airplanes manufactured and delivered before April 1, 2008, may have received on the productionline a partial or incorrect implementation of the required ATR mod. No. 05780. For the reasons stated above, the present AD requires an inspection of the identified airplanes to verify and, finalize when necessary, the complete and correct implementation of the ATR mod. No. 05780[.] 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. The unsafe condition is loss of the rudder trim, pitch trim, and stick pusher control, which could result in loss of control of the airplane.

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.

(Agusta) Model A109E, A109S, A119, and AW119MKII helicopters. 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 European Aviation Safety Agency (EASA), the Technical Agent for the aviation authority of Italy, with which we have a bilateral agreement, has issued an MCAI AD which states that two cases of cracks on a certain cargo hook lever (lever) have been reported by the manufacturer of the cargo hook. This lever is a critical structural component of the cargo hook, and a crack could result in inadvertent loss of the cargo hook load. This AD requires actions that are intended to address the unsafe condition caused by cracks in the cargo hook lever. DATES: This AD becomes effective on July 17, 2009.

That NPRM was published in the Federal Register on March 23, 2009 (74 FR 12096). That NPRM proposed to require actions that are intended to detect a crack in the cargo hook lever and prevent the inadvertent loss of the cargo hook load. You may obtain further information by examining the MCAI and any related service information in the AD docket. Comments By publishing the NPRM, we gave the public an opportunity to participate in developing this AD. However, we received no comment on the NPRM or on our determination of the cost to the public. Therefore, based on our review and evaluation of the available data, we have determined that air safety and the public interest require adopting the AD as proposed. Relevant Service Information Agusta has issued Alert Bollettino Tecnico (ABT) No. 109EP–78, ABT No. 109S–12, and ABT No. 119–21, all dated June 6, 2007. The actions described in the MCAI are intended to correct the same unsafe condition as that identified in the service information. Differences Between This AD and the MCAI We have reviewed the MCAI and, in general, agree with its substance. However, we have made the following changes: • Excluded the August 31, 2007 compliance date because that date has passed; • Excluded the Model A109LUH from the applicability and do not reference Agusta ABT No. 109L–006 because the Model A109LUH helicopter is not on the U.S. type certificate, H7EU; • Added the Model AW119MKII to the applicability; • Required the use of a 10-power or higher magnifying glass to accomplish the visual inspections; and • Excluded the kit installation part number (P/N), relying instead on the cargo hook and lever P/N. These differences are highlighted in the ‘‘Differences Between this AD and the MCAI’’ section in this AD. Costs of Compliance We estimate that this AD will affect about 26 helicopters on the U.S. E:\FR\FM\12JNR1.SGM 12JNR1

SUPPLEMENTARY INFORMATION:

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 2008-0218, dated December 10, 2008 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Identification of an unsafe condition related to the loss of the 
fail-safe design criteria for the rudder trim, pitch trim and stick 
pusher control functions after a reported event led in April 2008 to 
the release of AD 2008-0062 to mandate the ATR modification No. 
05780.
    It has appeared that some airplanes manufactured and delivered 
before April 1, 2008, may have received on the production-line a 
partial or incorrect implementation of the required ATR mod. No. 
05780.
    For the reasons stated above, the present AD requires an 
inspection of the identified airplanes to verify and, finalize when 
necessary, the complete and correct implementation of the ATR mod. 
No. 05780[.]

The unsafe condition is loss of the rudder trim, pitch trim, and stick 
pusher control, which could result in loss of control of the airplane. 
Correct implementation of ATR modification No. 05780 includes 
inspecting the protection sleeves for correct installation, and 
installing new protective sleeving on the wire bundles in the rear 
baggage zone if necessary; doing a detailed inspection for correct 
positioning of the clamps for the wire bundles, and re-installing them 
if necessary. You may obtain further information by examining the MCAI 
in the AD docket.

Relevant Service Information

    Avions de Transport Regional has issued Service Bulletins ATR42-92-
0020 and ATR72-92-1021, both dated October 17, 2008. 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.
    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future.

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

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

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

[[Page 27912]]

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-2009-0524; Directorate Identifier 
2009-NM-030-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 
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.

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

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2009-12-12 ATR--GIE Avions de Transport R[eacute]gional (Formerly 
Aerospatiale): Amendment 39-15935. Docket No. FAA-2009-0524; 
Directorate Identifier 2009-NM-030-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective June 29, 
2009.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to the airplanes identified in paragraphs 
(c)(1) and (c)(2) of the AD, certificated in any category.
    (1) ATR Model ATR42-500 airplanes, manufacturer serial numbers 
(MSNs) 667, 669, and 671.
    (2) ATR Model ATR72-212A airplanes, MSNs 756 to 784 inclusive, 
except MSNs 770, 773, and 783.

Subject

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

Reason

    (e) The mandatory continued airworthiness information (MCAI) 
states:

    Identification of an unsafe condition related to the loss of the 
fail-safe design criteria for the rudder trim, pitch trim and stick 
pusher control functions after a reported event led in April 2008 to 
the release of AD 2008-0062 to mandate the ATR modification No. 
05780.
    It has appeared that some airplanes manufactured and delivered 
before April 1, 2008, may have received on the production-line a 
partial or incorrect implementation of the required ATR mod. No. 
05780.
    For the reasons stated above, the present AD requires an 
inspection of the identified airplanes to verify and, finalize when 
necessary, the complete and correct implementation of the ATR mod. 
No. 05780[.]

The unsafe condition is loss of the rudder trim, pitch trim, and 
stick pusher control, which could result in loss of control of the 
airplane. Correct implementation of ATR modification No. 05780 
includes inspecting the protection sleeves for correct installation, 
and installing new protective sleeving on the wire bundles in the 
rear baggage zone if necessary; doing a detailed inspection for 
correct positioning of the clamps for the wire bundles, and re-
installing them if necessary.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) Within 550 flight hours after the effective date of this AD, 
do a detailed inspection to verify the installation of the correct 
protection sleeves and the correct routing and clamping of the wire 
bundles. Do the actions in accordance with the Accomplishment 
Instructions of Avions de Transport Regional Service Bulletin ATR42-
92-0020 or ATR72-92-1021, both dated October 17, 2008; as 
applicable.
    (2) If any discrepancy is found during the inspection required 
by paragraph (f)(1) of this AD, before further flight, do all 
applicable corrective actions in accordance with the Accomplishment 
Instructions of Avions de Transport Regional Service Bulletin ATR42-
92-0020 or ATR72-92-1021, both dated October 17, 2008; as 
applicable.
