ACTION: Final rule. AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as electrical arcing due to chafing between a bonding cable and electrical wires in the 120 VU (volt unit) electrical harness, causing the loss of some instruments and loss of one hydraulic circuit pressure (i.e., loss of pressure of one hydraulic circuit). We are issuing this AD to require actions to correct the unsafe condition on these products. This AD becomes effective July 19, 2007. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of July 19, 2007. ADDRESSES: You may examine the AD docket on the Internet at https:// dms.dot.gov or in person at the Docket Management Facility, U.S. Department of Transportation, 400 Seventh Street, SW., Nassif Building, Room PL–401, Washington, DC. FOR FURTHER INFORMATION CONTACT: Tom Rodriguez, Aerospace Engineer, International Branch, ANM–116, FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington 98057–3356; telephone (425) 227–1137; fax (425) 227–1149. SUPPLEMENTARY INFORMATION: DATES: PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 Discussion 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 allow 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 AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The AD contains text copied from the MCAI and for this reason might not follow our plain language principles. 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 March 2, 2007 (72 FR 9475). That NPRM proposed to require inspecting the harness installation in the 120 VU (volt unit) electrical harness and, as applicable, restoring correct installation of the bonding cable. The MCAI states that recently an ATR 42 suffered electrical arcing, causing the loss of some instruments and loss of one hydraulic circuit pressure (i.e., loss of pressure of one hydraulic circuit) due to chafing between a bonding cable and electrical wires in the 120 VU electrical harness. The investigation showed that a tubular support had been deformed and therefore impaired the spacing among electrical harness, supports, and cables; the harness was not correctly attached; the size of the harness was increased by addition of cables (for Service Bulletins (SB) or customer modifications embodiments); and the bonding cable was not correctly installed. The MCAI mandates an inspection of the ATR 42 and ATR 72 fleet for correct installation of the bonding cable and restoring correct installation of the bonding cable if necessary. Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. Request To Include Revised Service Bulletins Avions de Transport Regional (ATR) states that in the NPRM reference is made to Avions de Transport Regional E:\FR\FM\14JNR1.SGM 14JNR1 Federal Register / Vol. 72, No. 114 / Thursday, June 14, 2007 / Rules and Regulations Service Bulletins ATR42–92–0012 and ATR72–92–1013, both dated July 4, 2006. ATR notes that this corresponds to the original issue of both service bulletins, and adds that those bulletins have been revised to add a reference to European Aviation Safety Agency Airworthiness Directive 2006–0283. ATR states that nothing else has been changed, and suggests that the AD reference Avions de Transport Regional Service Bulletins ATR42–92–0012 and ATR72–92–1013, both Revision 01, both dated December 7, 2006. We agree to reference Revision 01 of the service bulletins in the AD. We have reviewed Revision 01 of the service bulletins, and the procedures are essentially the same as those in the original issues, as noted by ATR. We have changed paragraphs (e) and (g) of this AD to specify Revision 01 of the service bulletins. Conclusion We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the change described previously. We determined that this change will not increase the economic burden on any operator or increase the scope of the AD. 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 a U.S. court of law. 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 our FAA policies. Any such differences are described in a separate paragraph of the AD. These requirements, if any, take precedence over the actions copied from the MCAI. pwalker on PROD1PC71 with RULES Costs of Compliance Based on the service information, we estimate that this AD affects about 53 products of U.S. registry. We also estimate that it takes about 1 work-hour per product to comply with this AD. The average labor rate is $80 per workhour. Based on these figures, we estimate the cost of the inspection on U.S. operators to be $4,240, or $80 per product. VerDate Aug<31>2005 17:11 Jun 13, 2007 Jkt 211001 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 that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) Is not a ‘‘significant rule’’ under 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://dms.dot.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647– 5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) issued by an airworthiness authority 
of another country to identify and correct an unsafe condition on an 
aviation product. The MCAI describes the unsafe condition as electrical 
arcing due to chafing between a bonding cable and electrical wires in 
the 120 VU (volt unit) electrical harness, causing the loss of some 
instruments and loss of one hydraulic circuit pressure (i.e., loss of 
pressure of one hydraulic circuit). We are issuing this AD to require 
actions to correct the unsafe condition on these products.

DATES: This AD becomes effective July 19, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 19, 
2007.

SUPPLEMENTARY INFORMATION:

Discussion

    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 allow 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 AD references the MCAI and related service information that we 
considered in forming the engineering basis to correct the unsafe 
condition. The AD contains text copied from the MCAI and for this 
reason might not follow our plain language principles.
    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 March 2, 2007 (72 FR 
9475). That NPRM proposed to require inspecting the harness 
installation in the 120 VU (volt unit) electrical harness and, as 
applicable, restoring correct installation of the bonding cable. The 
MCAI states that recently an ATR 42 suffered electrical arcing, causing 
the loss of some instruments and loss of one hydraulic circuit pressure 
(i.e., loss of pressure of one hydraulic circuit) due to chafing 
between a bonding cable and electrical wires in the 120 VU electrical 
harness. The investigation showed that a tubular support had been 
deformed and therefore impaired the spacing among electrical harness, 
supports, and cables; the harness was not correctly attached; the size 
of the harness was increased by addition of cables (for Service 
Bulletins (SB) or customer modifications embodiments); and the bonding 
cable was not correctly installed. The MCAI mandates an inspection of 
the ATR 42 and ATR 72 fleet for correct installation of the bonding 
cable and restoring correct installation of the bonding cable if 
necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received.

Request To Include Revised Service Bulletins

    Avions de Transport Regional (ATR) states that in the NPRM 
reference is made to Avions de Transport Regional

[[Page 32779]]

Service Bulletins ATR42-92-0012 and ATR72-92-1013, both dated July 4, 
2006. ATR notes that this corresponds to the original issue of both 
service bulletins, and adds that those bulletins have been revised to 
add a reference to European Aviation Safety Agency Airworthiness 
Directive 2006-0283. ATR states that nothing else has been changed, and 
suggests that the AD reference Avions de Transport Regional Service 
Bulletins ATR42-92-0012 and ATR72-92-1013, both Revision 01, both dated 
December 7, 2006.
    We agree to reference Revision 01 of the service bulletins in the 
AD. We have reviewed Revision 01 of the service bulletins, and the 
procedures are essentially the same as those in the original issues, as 
noted by ATR. We have changed paragraphs (e) and (g) of this AD to 
specify Revision 01 of the service bulletins.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the change described previously. We determined that this change 
will not increase the economic burden on any operator or increase the 
scope of the AD.

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 a U.S. court of 
law. 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 our FAA policies. Any such differences 
are described in a separate paragraph of the AD. These requirements, if 
any, take precedence over the actions copied from the MCAI.

Costs of Compliance

    Based on the service information, we estimate that this AD affects 
about 53 products of U.S. registry. We also estimate that it takes 
about 1 work-hour per product to comply with this AD. The average labor 
rate is $80 per work-hour. Based on these figures, we estimate the cost 
of the inspection on U.S. operators to be $4,240, or $80 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 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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://
dms.dot.gov; or in person at the Docket Management Facility between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains the NPRM, the regulatory evaluation, any comments 
received, and other information. The street address for the Docket 
Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments 
will be available in the AD docket shortly after receipt.

27358; Directorate Identifier 2006-NM-270-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective July 19, 
2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model ATR42-200, -300, -320, and -500 
airplanes; all serial numbers up to manufacturer serial number (MSN) 
643 inclusive; and Model ATR72-101, -102, -201, -202, -211, -212, 
and -212A airplanes, all serial numbers up to MSN 728 inclusive, 
except MSN 723 and 725; certificated in any category.

Reason

    (d) The mandatory continuing airworthiness information (MCAI) 
states that recently an ATR 42 suffered electrical arcing, causing 
the loss of some instruments and loss of one hydraulic circuit 
pressure (i.e., loss of pressure of one hydraulic circuit) due to 
chafing between a bonding cable and electrical wires in the 120 VU 
(volt unit) electrical harness. The investigation showed that a 
tubular support had been deformed and therefore impaired the spacing 
among electrical harness, supports, and cables; the harness was not 
correctly attached; the size of the harness was increased by 
addition of cables (for Service Bulletins (SB) or customer 
modifications embodiments); and the bonding cable was not correctly 
installed. The MCAI mandates an inspection of the ATR 42 and ATR 72 
fleet for correct installation of the bonding cable and restoring 
correct installation of the bonding cable if necessary.

Actions and Compliance

    (e) Unless already done, do the following actions. Within 3 
months after the effective date of this AD: Inspect the harness 
installation in the 120 VU electrical harness and, as applicable, 
restore correct installation of the bonding cable, in accordance 
with the instructions given by Avions de Transport
