SUPPLEMENTARY INFORMATION: 14 CFR Part 39 Discussion DEPARTMENT OF TRANSPORTATION [Docket No. FAA–2011–0721; Directorate Identifier 2010–NM–217–AD; Amendment 39–16861; AD 2011–23–10] RIN 2120–AA64 Airworthiness Directives; ATR–GIE ´ Avions de Transport Regional Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Model ATR42 and ATR72 airplanes. 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: SUMMARY: One ATR operator has experienced inflight elevator travel limitations with unusual effort being necessary on pitch axis to control the aeroplane, while the ‘‘pitch mistrim’’ message appeared on the ADU [advisory display unit] display. The elevators seemed to be jammed. During the post-flight inspection, it was discovered that the LH [left-hand] elevator lower stop assembly was broken at the level of the angles, which may have prevented the elevator to respond normally to the flight control input. This condition, if not detected and corrected, could lead to reduced control of the aeroplane. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective December 15, 2011. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of December 15, 2011. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC. FOR FURTHER INFORMATION CONTACT: Tom Rodriguez, Aerospace Engineer, International Branch, ANM–116, Transport Airplane Directorate, FAA, 1601 Lind Avenue SW., Renton, PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on August 5, 2011 (76 FR 47520). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: One ATR operator has experienced inflight elevator travel limitations with unusual effort being necessary on pitch axis to control the aeroplane, while the ‘‘pitch mistrim’’ message appeared on the ADU display. The elevators seemed to be jammed. During the post-flight inspection, it was discovered that the LH elevator lower stop assembly was broken at the level of the angles, which may have prevented the elevator to respond normally to the flight control input. This condition, if not detected and corrected, could lead to reduced control of the aeroplane. For the reasons described above, and as a precautionary measure, this [EASA] AD requires a one-time [general visual and detailed] inspection [for damaged angles] of the elevator hinge fittings and the reporting of all findings. Depending on the results, further action may be considered. Corrective actions also include replacement of damaged angles with serviceable parts; and a detailed inspection of adjacent areas for damage, and repair if necessary. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (76 FR 47520), August 5, 2011) or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. 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. E:\FR\FM\10NOR1.SGM 10NOR1 Federal Register / Vol. 76, No. 218 / Thursday, November 10, 2011 / Rules and Regulations We might also have required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a NOTE within the AD. 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. Costs of Compliance We estimate that this AD will affect 86 products of U.S. registry. We also estimate that it will take about 4 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $29,240, or $340 per product. In addition, we estimate that any necessary follow-on actions would take about 60 work-hours and require parts costing $960, for a cost of $6,060 per product. We have no way of determining the number of products that may need these actions. Examining the AD Docket You may examine the AD docket on the Internet at https:// 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.

Airworthiness Directives; ATR-GIE Avions de Transport 
R[eacute]gional Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Model ATR42 and ATR72 airplanes. 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:

    One ATR operator has experienced in-flight elevator travel 
limitations with unusual effort being necessary on pitch axis to 
control the aeroplane, while the ``pitch mistrim'' message appeared 
on the ADU [advisory display unit] display. The elevators seemed to 
be jammed.
    During the post-flight inspection, it was discovered that the LH 
[left-hand] elevator lower stop assembly was broken at the level of 
the angles, which may have prevented the elevator to respond 
normally to the flight control input.
    This condition, if not detected and corrected, could lead to 
reduced control of the aeroplane.
* * * * *

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective December 15, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 15, 
2011.

ADDRESSES: You may examine the AD docket on the Internet at https://www.regulations.gov or in person at the U.S. Department of

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on August 5, 2011 (76 
FR 47520). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    One ATR operator has experienced in-flight elevator travel 
limitations with unusual effort being necessary on pitch axis to 
control the aeroplane, while the ``pitch mistrim'' message appeared 
on the ADU display. The elevators seemed to be jammed.
    During the post-flight inspection, it was discovered that the LH 
elevator lower stop assembly was broken at the level of the angles, 
which may have prevented the elevator to respond normally to the 
flight control input.
    This condition, if not detected and corrected, could lead to 
reduced control of the aeroplane.
    For the reasons described above, and as a precautionary measure, 
this [EASA] AD requires a one-time [general visual and detailed] 
inspection [for damaged angles] of the elevator hinge fittings and 
the reporting of all findings. Depending on the results, further 
action may be considered.

Corrective actions also include replacement of damaged angles with 
serviceable parts; and a detailed inspection of adjacent areas for 
damage, and repair if necessary. You may obtain further information by 
examining the MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (76 FR 47520), August 5, 
2011) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

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.

[[Page 70045]]

    We might also have required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 86 products of U.S. registry. 
We also estimate that it will take about 4 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD to the U.S. operators to be $29,240, or $340 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 60 work-hours and require parts costing $960, for a cost of 
$6,060 per product. We have no way of determining the number of 
products that may need these actions.

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.

Examining the AD Docket

    You may examine the AD docket on the Internet at https://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 the NPRM (76 FR 47520, August 5, 
2011), the regulatory evaluation, any comments received, and other

    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:

2011-23-10 ATR-GIE Avions de Transport R[eacute]gional: Amendment 
39-16861. Docket No. FAA-2011-0721; Directorate Identifier 2010-NM-
217-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective December 
15, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to ATR-GIE Avions de Transport 
R[eacute]gional Model ATR42-200, -300, -320, and -500 airplanes, all 
manufacturer serial numbers (MSN) up to MSN 643 inclusive; and Model 
ATR72-101, -102, -201, -202, -211, -212, and -212A airplanes, all 
MSNs up to MSN 728 inclusive; certificated in any category.

Subject

    (d) Air Transport Association (ATA) of America Code 55: 
Stabilizers.

Reason

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

    One ATR operator has experienced in-flight elevator travel 
limitations with unusual effort being necessary on pitch axis to 
control the aeroplane, while the ``pitch mistrim'' message appeared 
on the ADU [advisory display unit] display. The elevators seemed to 
be jammed.
    During the post-flight inspection, it was discovered that the LH 
[left-hand] elevator lower stop assembly was broken at the level of 
the angles, which may have prevented the elevator to respond 
normally to the flight control input.
    This condition, if not detected and corrected, could lead to 
reduced control of the aeroplane.

FAA AD Differences

    Note 1: This AD differs from the MCAI and/or service information 
as follows: No differences.

Other FAA AD Provisions

    (i) 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: Tom Rodriguez, Aerospace Engineer, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
1601 Lind Avenue SW., Renton, Washington 98057-3356; telephone (425) 
227-1137; fax (425) 227-1149. Information may be emailed 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.
    (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: A federal agency may not conduct or 
sponsor, and a person is not required to respond to, nor shall a 
person be subject to a penalty for failure to comply with a 
collection of information subject to the requirements of the 
Paperwork Reduction Act unless that collection of information 
displays a current valid OMB Control Number. The OMB Control Number 
for this information collection is 2120-0056. Public reporting for 
this collection of information is estimated to be approximately 5 
minutes per response, including the time for reviewing instructions, 
completing and reviewing the collection of information. All 
responses to this collection of information are mandatory. Comments 
concerning the accuracy of this burden and suggestions for reducing 
the burden should be directed to the FAA at: 800 Independence Ave.
