ACTION: Final rule; request for comments. AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Aerospatiale Model ATR42–500 and ATR72–212A series airplanes, that requires repetitive inspections for cracking of the upper closing rib of the vertical fin, related investigative actions, and corrective actions if necessary. This new AD requires modifying the installation of the vertical leading edge fairing at the fin tip, which ends the repetitive inspections. This AD results from a report that rudder operation difficulties occurred on a Model ATR42–500 series airplane while the airplane was on the ground. We are issuing this AD to prevent interference between the upper closing rib and the rudder, which could result in a rudder jam and consequent reduced controllability of the airplane. DATES: This AD becomes effective September 5, 2006. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of September 5, 2006. On July 22, 2004 (69 FR 33834, June 17, 2004), the Director of the Federal Register approved the incorporation by reference of certain other publications listed in the AD. We must receive comments on this AD by October 20, 2006.

SUPPLEMENTARY INFORMATION: Discussion On June 7, 2004, we issued AD 2004– 12–13, amendment 39–13672 (69 FR 33834, June 17, 2004), for certain Aerospatiale Model ATR42–500 and ATR72–212A series airplanes. That AD requires repetitive inspections for cracking of the upper closing rib of the vertical fin, related investigative actions, and corrective actions if necessary. That AD resulted from a report that rudder operation difficulties occurred on a Model ATR42–500 series airplane while the airplane was on the ground. We issued that AD to prevent interference between the upper closing rib and the rudder, which could result in a rudder jam and consequent reduced controllability of the airplane. rmajette on PROD1PC67 with RULES Actions Since Existing AD Was Issued Since we issued AD 2004–12–13, the Direction Gonorale de l’Aviation Civile (DGAC), which is the airworthiness authority for France, notified us that the manufacturer developed a terminating modification for the repetitive inspections of the existing AD. Relevant Service Information Avions de Transport Regional has issued Service Bulletin ATR42–55– 0012, Revision 2, including Accomplishment Report, dated June 28, 2005 (for Model ATR42–500 airplanes); and ATR72–55–1004, Revision 3, including Accomplishment Report, dated September 23, 2005 (for Model ATR72–212 airplanes). The service bulletins describe procedures for modifying the installation of the vertical leading edge fairing at the fin tip. The modification includes doing a detailed inspection for cracking, misplacement, or deformation of the upper closing rib of the vertical fin. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DGAC mandated the VerDate Aug<31>2005 15:07 Aug 18, 2006 Jkt 208001 service information and issued French airworthiness directive F–2005–059, dated April 13, 2005, to ensure the continued airworthiness of these airplanes in France. Avions de Transport Regional Service Bulletin ATR42–55–0012 refers to Avions de Transport Regional Service Bulletin ATR42–55–0011, dated September 26, 2002 (for Model ATR42– 500 airplanes), as the appropriate source of service information for doing the detailed inspection. Avions de Transport Regional Service Bulletin ATR72–55–1004 refers to Avions de Transport Regional Service Bulletin ATR72–55–1003, Revision 1, dated November 13, 2002 (for Model ATR72– 212 airplanes), as the appropriate source of service information for doing the detailed inspection. FAA’s Determination and Requirements of This AD These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. We have examined the DGAC’s findings, evaluated all pertinent information, and determined that we need to issue an AD for products of this type design that are certificated for operation in the United States. Therefore, we are issuing this AD to prevent interference between the upper closing rib and the rudder, which could result in a rudder jam and consequent reduced controllability of the airplane. This AD supersedes AD 2004–12–13 and retains the requirements of the existing AD. This AD also requires modifying the installation of the vertical leading edge fairing at the fin tip, which terminates the repetitive inspection requirements of the existing AD. Change to Existing AD This AD retains all requirements of AD 2004–12–13. Since AD 2004–12–13 was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this AD, as listed in the following table: REVISED PARAGRAPH IDENTIFIERS Requirement in AD 2004– 12–13 Paragraph (a) ...................... PO 00000 Frm 00021 Fmt 4700 Corresponding requirement in this AD Paragraph (f). Sfmt 4700 REVISED PARAGRAPH IDENTIFIERS— Continued Requirement in AD 2004– 12–13 Corresponding requirement in this AD Paragraph (b) ...................... Paragraph (c) ...................... Paragraph (d) ...................... Paragraph (g). Paragraph (h). Paragraph (i). Explanation of Change to Applicability We have revised the applicability of the existing AD to identify model designations as published in the most recent type certificate data sheet for the affected models. Explanation of Change Made to Requirements of Existing AD Paragraph (d) of the existing AD specifies making repairs using a method approved by either the FAA or the ´ ´ Direction Generale de l’Aviation Civile (or its delegated agent). The European Aviation Safety Agency (EASA) has assumed responsibility for the airplane models that are subject to this AD. Therefore, we have revised paragraph (i) of this AD to specify making repairs using a method approved by either the FAA or the EASA (or its delegated agent). Clarification of Detailed Inspection Definition For clarification, we have revised the definition of a ‘‘detailed inspection’’ in this AD. Costs of Compliance None of the airplanes affected by this action are on the U.S. Register. All airplanes affected by this AD are currently operated by non-U.S. operators under foreign registry; therefore, they are not directly affected by this AD action. However, we consider this AD necessary to ensure that the unsafe condition is addressed if any affected airplane is imported and placed on the U.S. Register in the future. If an affected airplane is imported and placed on the U.S. Register in the future, the currently required inspections will take approximately 2 work hours per airplane to accomplish, at an average labor rate of $80 per work hour. Based on these figures, the currently required inspections of this AD on U.S. operators are estimated to be $160 per airplane. If an affected airplane is imported and placed on the U.S. Register in the future, the required modification of this new AD will take between 16 and 40 work hours per airplane to accomplish, at an average labor rate of $80 per work hour. The required parts will cost between approximately $1,700 and $9,260. Based E:\FR\FM\21AUR1.SGM 21AUR1 48468 Federal Register / Vol. 71, No. 161 / Monday, August 21, 2006 / Rules and Regulations on these figures, the required modification of this AD on U.S. operators is estimated to be between $2,980 and $12,460 per airplane. FAA’s Determination of the Effective Date No airplane affected by this AD is currently on the U.S. Register. Therefore, providing notice and opportunity for public comment is unnecessary before this AD is issued, and this AD may be made effective in less than 30 days after it is published in the Federal Register. Comments Invited This AD is a final rule that involves requirements that affect flight safety and was not preceded by notice and an opportunity for public comment; however, we invite you to submit any relevant written data, views, or arguments regarding this AD. Send your comments to an address listed in the ADDRESSES section. Include ‘‘Docket No. FAA–2006–25610; Directorate Identifier 2005–NM–260–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the AD that might suggest a need to modify it. 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 with FAA personnel concerning this AD. Using the search function of that Web site, anyone can find and read the comments in any of our dockets, including the name of the individual who sent the comment (or signed the comment on behalf of an association, business, labor union, etc.). You may review the DOT’s complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477–78), or you may visit https://dms.dot.gov. rmajette on PROD1PC67 with RULES Examining the Docket You may examine the AD docket on the Internet at https://dms.dot.gov, or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647–5227) is located on the plaza level of the Nassif Building at the DOT street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after the Docket Management System receives them. VerDate Aug<31>2005 16:48 Aug 18, 2006 Jkt 208001 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 have 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 that the 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 AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.

Airworthiness Directives; Aerospatiale Model ATR42-500 Airplanes 
and Model ATR72-212A Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to certain Aerospatiale Model ATR42-500 and ATR72-
212A series airplanes, that requires repetitive inspections for 
cracking of the upper closing rib of the vertical fin, related 
investigative actions, and corrective actions if necessary. This new AD 
requires modifying the installation of the vertical leading edge 
fairing at the fin tip, which ends the repetitive inspections. This AD 
results from a report that rudder operation difficulties occurred on a 
Model ATR42-500 series airplane while the airplane was on the ground. 
We are issuing this AD to prevent interference between the upper 
closing rib and the rudder, which could result in a rudder jam and 
consequent reduced controllability of the airplane.

DATES: This AD becomes effective September 5, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of September 5, 
2006.
    On July 22, 2004 (69 FR 33834, June 17, 2004), the Director of the 
Federal Register approved the incorporation by reference of certain 
other publications listed in the AD.
    We must receive comments on this AD by October 20, 2006.

SUPPLEMENTARY INFORMATION:

Discussion

    On June 7, 2004, we issued AD 2004-12-13, amendment 39-13672 (69 FR 
33834, June 17, 2004), for certain Aerospatiale Model ATR42-500 and 
ATR72-212A series airplanes. That AD requires repetitive inspections 
for cracking of the upper closing rib of the vertical fin, related 
investigative actions, and corrective actions if necessary. That AD 
resulted from a report that rudder operation difficulties occurred on a 
Model ATR42-500 series airplane while the airplane was on the ground. 
We issued that AD to prevent interference between the upper closing rib 
and the rudder, which could result in a rudder jam and consequent 
reduced controllability of the airplane.

Actions Since Existing AD Was Issued

    Since we issued AD 2004-12-13, the Direction Gonorale de l'Aviation 
Civile (DGAC), which is the airworthiness authority for France, 
notified us that the manufacturer developed a terminating modification 
for the repetitive inspections of the existing AD.

Relevant Service Information

    Avions de Transport Regional has issued Service Bulletin ATR42-55-
0012, Revision 2, including Accomplishment Report, dated June 28, 2005 
(for Model ATR42-500 airplanes); and ATR72-55-1004, Revision 3, 
including Accomplishment Report, dated September 23, 2005 (for Model 
ATR72-212 airplanes). The service bulletins describe procedures for 
modifying the installation of the vertical leading edge fairing at the 
fin tip. The modification includes doing a detailed inspection for 
cracking, misplacement, or deformation of the upper closing rib of the 
vertical fin.
    Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition. The DGAC mandated 
the service information and issued French airworthiness directive F-
2005-059, dated April 13, 2005, to ensure the continued airworthiness 
of these airplanes in France.
    Avions de Transport Regional Service Bulletin ATR42-55-0012 refers 
to Avions de Transport Regional Service Bulletin ATR42-55-0011, dated 
September 26, 2002 (for Model ATR42-500 airplanes), as the appropriate 
source of service information for doing the detailed inspection. Avions 
de Transport Regional Service Bulletin ATR72-55-1004 refers to Avions 
de Transport Regional Service Bulletin ATR72-55-1003, Revision 1, dated 
November 13, 2002 (for Model ATR72-212 airplanes), as the appropriate 
source of service information for doing the detailed inspection.

FAA's Determination and Requirements of This AD

    These airplane models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness agreement. Pursuant to this 
bilateral airworthiness agreement, the DGAC has kept the FAA informed 
of the situation described above. We have examined the DGAC's findings, 
evaluated all pertinent information, and determined that we need to 
issue an AD for products of this type design that are certificated for 
operation in the United States.
    Therefore, we are issuing this AD to prevent interference between 
the upper closing rib and the rudder, which could result in a rudder 
jam and consequent reduced controllability of the airplane. This AD 
supersedes AD 2004-12-13 and retains the requirements of the existing 
AD. This AD also requires modifying the installation of the vertical 
leading edge fairing at the fin tip, which terminates the repetitive 
inspection requirements of the existing AD.

Change to Existing AD

    This AD retains all requirements of AD 2004-12-13. Since AD 2004-
12-13 was issued, the AD format has been revised, and certain 
paragraphs have been rearranged. As a result, the corresponding 
paragraph identifiers have changed in this AD, as listed in the 
following table:

                      Revised Paragraph Identifiers
------------------------------------------------------------------------
                                           Corresponding requirement in
      Requirement in AD 2004-12-13                    this AD
------------------------------------------------------------------------
Paragraph (a)...........................  Paragraph (f).
Paragraph (b)...........................  Paragraph (g).
Paragraph (c)...........................  Paragraph (h).
Paragraph (d)...........................  Paragraph (i).
------------------------------------------------------------------------

Explanation of Change to Applicability

    We have revised the applicability of the existing AD to identify 
model designations as published in the most recent type certificate 
data sheet for the affected models.

Explanation of Change Made to Requirements of Existing AD

    Paragraph (d) of the existing AD specifies making repairs using a 
method approved by either the FAA or the Direction 
G[eacute]n[eacute]rale de l'Aviation Civile (or its delegated agent). 
The European Aviation Safety Agency (EASA) has assumed responsibility 
for the airplane models that are subject to this AD. Therefore, we have 
revised paragraph (i) of this AD to specify making repairs using a 
method approved by either the FAA or the EASA (or its delegated agent).

Clarification of Detailed Inspection Definition

    For clarification, we have revised the definition of a ``detailed 
inspection'' in this AD.

Costs of Compliance

    None of the airplanes affected by this action are on the U.S. 
Register. All airplanes affected by this AD are currently operated by 
non-U.S. operators under foreign registry; therefore, they are not 
directly affected by this AD action. However, we consider this AD 
necessary to ensure that the unsafe condition is addressed if any 
affected airplane is imported and placed on the U.S. Register in the 
future.
    If an affected airplane is imported and placed on the U.S. Register 
in the future, the currently required inspections will take 
approximately 2 work hours per airplane to accomplish, at an average 
labor rate of $80 per work hour. Based on these figures, the currently 
required inspections of this AD on U.S. operators are estimated to be 
$160 per airplane.
    If an affected airplane is imported and placed on the U.S. Register 
in the future, the required modification of this new AD will take 
between 16 and 40 work hours per airplane to accomplish, at an average 
labor rate of $80 per work hour. The required parts will cost between 
approximately $1,700 and $9,260. Based

[[Page 48468]]

on these figures, the required modification of this AD on U.S. 
operators is estimated to be between $2,980 and $12,460 per airplane.

FAA's Determination of the Effective Date

    No airplane affected by this AD is currently on the U.S. Register. 
Therefore, providing notice and opportunity for public comment is 
unnecessary before this AD is issued, and this AD may be made effective 
in less than 30 days after it is published in the Federal Register.

Comments Invited

    This AD is a final rule that involves requirements that affect 
flight safety and was not preceded by notice and an opportunity for 
public comment; however, we invite you to submit any relevant written 
data, views, or arguments regarding this AD. Send your comments to an 
address listed in the ADDRESSES section. Include ``Docket No. FAA-2006-
25610; Directorate Identifier 2005-NM-260-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the AD that might 
suggest a need to modify it.
    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 with FAA 
personnel concerning this AD. Using the search function of that Web 
site, anyone can find and read the comments in any of our dockets, 
including the name of the individual who sent the comment (or signed 
the comment on behalf of an association, business, labor union, etc.). 
You may review the DOT's complete Privacy Act Statement in the Federal 
Register published on April 11, 2000 (65 FR 19477-78), or you may visit 
https://dms.dot.gov.

Examining the Docket

    You may examine the AD docket on the Internet at https://
dms.dot.gov, or in person at the Docket Management Facility office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the DOT 
street address stated in the ADDRESSES section. Comments will be 
available in the AD docket shortly after the Docket Management System 
receives them.

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 have 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 that the 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
