Download as PDF 20300 Federal Register / Vol. 72, No. 78 / Tuesday April 24, 2007 / Proposed Rules 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. 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. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: Piaggio Aero Industries S.p.A.: Docket No. FAA–2007–27723; Directorate Identifier 2007–CE–029–AD. Comments Due Date (a) We must receive comments by May 24, 2007. jlentini on PROD1PC65 with PROPOSAL Affected ADs (b) None. Applicability (c) This AD applies to Model P–180 airplanes, serial numbers 1002, 1004 through 1107, 1109, and 1110, certificated in any category. Subject (d) Air Transport Association of America (ATA) Code 57: Wings. VerDate Aug<31>2005 18:31 Apr 23, 2007 Jkt 211001 Reason (e) The mandatory continuing airworthiness information (MCAI) states: EASA EAD 2006–0072–E was issued on 31st March 2006 following a further failure of the forward support of the Main Wing Outboard Flap (MWOF), caused by corrosion. This condition, if not corrected, may cause surface twisting during deployment at landing. The analysis of that event highlighted the need for the reduction of the previous inspection interval which was mandated by ENAC through AD 2004–523, approved by EASA with reference 2004– 12521. Now the TC holder has developed a new type of forward support for the Main Wing Outboard Flap with characteristics that improve the resistance to corrosion. When the new support is installed, the repetitive Eddy current inspection that was introduced by EASA EAD 2006–0072–E is no longer required. Actions and Compliance (f) Unless already done, do the following actions: (1) Within the next 200 hours time-inservice (TIS) or 60 days after the effective date of this AD, whichever occurs first, replace the outboard flap track forward bushing and the outboard flap track forward support. Do the replacements using the Accomplishment Instructions detailed in Part A of Piaggio Aero Industries S.p.A. Mandatory Service Bulletin (SB) No. 80– 0210, Rev 4, dated July 19, 2006. (2) At intervals not to exceed 1,500 hours TIS after doing the replacements required in paragraph (f)(1) of this AD, visually inspect the outboard flap track forward support for traces of any kind of corrosion and/or protective coat/finishing wear damage. Do the inspections using the Accomplishment Instructions detailed in Part B of Piaggio Aero Industries S.p.A. Mandatory SB No. 80– 0210, Rev 4, dated July 19, 2006. (3) Before further flight after each inspection required in paragraph (f)(2) of this AD in which any kind of corrosion or wear damage is found, contact the manufacturer for a repair scheme and incorporate the repair. FAA AD Differences Note: This AD differs from the MCAI and/ or service information as follows: No differences.

Comments Invited FAA’s Determination and Requirements of the 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. 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–2007–27432; Directorate Identifier 2007–CE–017–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 post all comments we receive, without change, to https:// dms.dot.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 AD No. 2007– 0034, dated February 22, 2007 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: * * * a new life limit for engine and Nose Landing Gear (NLG) mounts installed on EADS SOCATA TB 9, TB 10 and TB 200 airplanes, as defined in the updated Airworthiness Limitations Section (ALS) of the relevant Aircraft Maintenance Manuals (AMM). The MCAI requires: * * * introduction of the new 10 000 Flight Hour life limit for engine and NLG mounts into the operator’s maintenance program through the Revision 18 of the AMM.

PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 Differences Between This Proposed 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 a Note within the proposed AD. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 146 products of U.S. registry. We also estimate that it would take about 0.5 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $5,840, or $40 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.

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-
27432; Directorate Identifier 2007-CE-017-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 because of those comments.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2007-0034, dated February 22, 2007 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

* * * a new life limit for engine and Nose Landing Gear (NLG) mounts 
installed on EADS SOCATA TB 9, TB 10 and TB 200 airplanes, as 
defined in the updated Airworthiness Limitations Section (ALS) of 
the relevant Aircraft Maintenance Manuals (AMM).
    The MCAI requires:
* * * introduction of the new 10 000 Flight Hour life limit for 
engine and NLG mounts into the operator's maintenance program 
through the Revision 18 of the AMM.

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

Relevant Service Information

    SOCATA--Groupe AEROSPATIALE has issued:
     SOCATA TB 9 Model Maintenance Manual, Original version 
dated September 1991, Revision 18, dated September 2006;
     SOCATA TB 10 Model Maintenance Manual, Original version 
dated September 1991, Revision 18, dated September 2006; and
     SOCATA TB 200 Model Maintenance Manual, Original version 
dated September 1991, Revision 18, dated September 2006.
    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the 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 this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed 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 a Note within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 146 products of U.S. registry. We also estimate that 
it would take about 0.5 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $5,840, or $40 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

[[Page 20302]]

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;

    (c) This AD applies to Model TB 9, TB 10, and TB 200 airplanes, 
all serial numbers, certificated in any category.

Subject

Limits.

Reason

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

* * * a new life limit for engine and Nose Landing Gear (NLG) mounts 
installed on EADS SOCATA TB 9, TB 10 and TB 200 airplanes, as 
defined in the updated Airworthiness Limitations Section (ALS) of 
the relevant Aircraft Maintenance Manuals (AMM).

effective date of this AD, incorporate the life limits in the 
Airworthiness Limitations documents presented in paragraphs (f)(1), 
(f)(2), or (f)(3) of this AD into the FAA-approved maintenance 
program. This may be done by updating the Airworthiness Limitations 
Section of the Airplane Maintenance Manual (AMM) and inserting the 
following applicable revision. The owner/operator holding at least a 
private pilot certificate as authorized by section 43.7 of the 
Federal Aviation Regulations (14 CFR 43.7) may do this action. Make 
an entry in the aircraft records showing compliance with this 
portion of the AD following section 43.9 of the Federal Aviation
