(EMBRAER) Model ERJ 190 Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). 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) 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: During aircraft structure fatigue tests, cracks were found in the wing lower skin stringers between ribs 7 and 10 on both wings. In order to prevent fatigue cracks in the wing lower skin stringers, which could result in fuel leakage and reduced structural integrity of the wing, the referred stringers must be reworked. PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 Date April 11, 2005. March 29, 2000. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective April 28, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of April 28, 2009. 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.

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 June 24, 2008 (73 FR 35597). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: E:\FR\FM\24MRR1.SGM 24MRR1 12234 Federal Register / Vol. 74, No. 55 / Tuesday, March 24, 2009 / Rules and Regulations During aircraft structure fatigue tests, cracks were found in the wing lower skin stringers between ribs 7 and 10 on both wings. In order to prevent fatigue cracks in the wing lower skin stringers, which could result in fuel leakage and reduced structural integrity of the wing, the referred stringers must be reworked. The corrective actions include spotfacing the lower wing stringers between ribs 7 and 10, doing a dye-penetrant inspection of the reworked stringers, shot-or flap-peening if no cracking is found, contacting the Manager, International Branch, ANM–116, Transport Airplane Directorate, FAA; or ˆ the Agencia Nacional de Aviacao Civil ¸˜ (ANAC) (or its delegated agent) if any crack is found, and repairing. mstockstill on PROD1PC66 with RULES Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Request To Include New Revision of Service Bulletin and New Inspection Option EMBRAER states that it has issued EMBRAER Service Bulletin 190–57– 0005, Revision 02, dated May 27, 2008. (We referred to EMBRAER Service Bulletin 190–57–0005, Revision 01, dated October 27, 2006, as the appropriate source of service information in the NPRM.) EMBRAER states that EMBRAER Service Bulletin 190–57–0005, Revision 02, dated May 27, 2008, provides procedures for an eddy current inspection rather than the dye-penetrant inspection method specified in EMBRAER Service Bulletin 190–57–0005, Revision 01, dated October 27, 2006. The eddy current inspection method uses equipment that is more appropriate for handling inside the fuel tank. EMBRAER states that airplanes already inspected using the dye-penetrant inspection method do not require additional inspection, and requests that EMBRAER Service Bulletin 190–57–0005, Revision 01, dated October 27, 2006, be considered an alternative method for complying with the NPRM. We agree that the eddy current inspection method specified in EMBRAER Service Bulletin 190–57– 0005, Revision 02, dated May 27, 2008, is an acceptable optional way to do the inspection for cracking of the reworked stringers. Therefore, we have revised paragraph (f) of this AD to specify that operators may accomplish either the dye-penetrant inspection in accordance with EMBRAER Service Bulletin 190– 57–0005, Revision 01, dated October 27, 2006, or the eddy current inspection in accordance with EMBRAER Service VerDate Nov<24>2008 01:02 Mar 24, 2009 Jkt 217001 Bulletin 190–57–0005, Revision 02, dated May 27, 2008. Request To Change Shot-Peening to Flap-Peening EMBRAER states that paragraph (f)(2)(i) of the NPRM should specify flap-peening of the reworked stringers if no cracking is found, rather than shotpeening as is specified in the NPRM. EMBRAER states that EMBRAER Service Bulletin 190–57–0005, Revision 02, dated May 27, 2008, specifies flap peening rather than shot peening. We partially agree. We agree with the request to specify flap-peening in paragraph (f)(2)(i) of the AD; however, we disagree with specifying only flap peening in that paragraph because shotpeening is also an acceptable method of compliance. Airplanes that are in compliance with EMBRAER Service Bulletin 190–57–0005, Revision 01, dated October 27, 2006, do not need additional action. We have revised paragraph (f)(2)(i) of this AD to specify that both shot peening and flap peening are acceptable methods of compliance. Request To Revise Contact for Repair Information EMBRAER requests that we revise paragraph (f)(2)(ii) of the NPRM to specify that operators may contact not ˆ only Agencia Nacional de Aviacao Civil ¸˜ (ANAC) for repair instructions if cracking is found, but also its delegated agent, or the Manager of the FAA’s Transport Airplane Directorate (TAD). We agree that contacting one of ANAC’s delegated agents or the TAD is appropriate. Therefore, we have changed paragraphs (e) and (f)(2)(ii) of this AD, and the last paragraph of the ‘‘Discussion’’ section, to specify that operators may also contact a delegated agent of ANAC, or the Manager of the TAD for repair instructions. Conclusion We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We determined that these changes 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 making PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 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 highlighted in a NOTE within the AD. Costs of Compliance We estimate that this AD will affect 18 products of U.S. registry. We also estimate that it will take 110 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $158,400 or $8,800 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 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.

ACTION: Final rule. mstockstill on PROD1PC66 with RULES SUMMARY: We are adopting a new airworthiness directive (AD) for certain Boeing Model 757–200, 757–200PF, and 757–300 series airplanes. This AD requires, for certain airplanes, measuring the electrical bond resistance at certain stations and doing any applicable repair; installing support brackets for the hot short protector and new support clamps for the wire bundles; installing the equipment of the hot short protector; and modifying an existing wire bundle and installing a new wire bundle. This AD also requires, for certain other airplanes, measuring the electrical bond resistance at certain stations, measuring the electrical bonding resistance between the hot short protector and rear spar web, and doing any applicable repair. This AD also requires revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the center fuel tank densitometer from overheating and becoming a potential ignition source inside the fuel tank, which, in combination with flammable fuel vapors, could result in a center fuel tank explosion and consequent loss of the airplane.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain Boeing Model 757–200, 757– 200PF, and 757–300 series airplanes. That NPRM was published in the Federal Register on August 7, 2008 (73 FR 45895). That NPRM proposed to require, for certain airplanes, measuring the electrical bond resistance at certain stations and doing any applicable repair; installing support brackets for the hot short protector and new support clamps for the wire bundles; installing the equipment of the hot short protector; and modifying an existing wire bundle and installing a new wire bundle. That NPRM also proposed to require, for certain other airplanes, measuring the electrical bond resistance at certain stations, measuring the electrical bonding resistance between the hot short protector and rear spar web, and doing any applicable repair. That NPRM also proposed to require revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness. Comments We gave the public the opportunity to participate in developing this AD. We considered the two comments received. PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 Support for the NPRM Boeing concurs with the NPRM. Request to Exempt Cargo-Only Airplanes Air Transport Association, on behalf of one of its members, UPS, proposes that cargo-only airplanes be exempt from installing the hot short protector specified in the NPRM, based on the same reasons used to exclude cargo-only airplanes in Federal Aviation Regulations change, ‘‘Reduction of Fuel Tank Flammability in Transport Category Airplanes,’’ Docket FAA– 2005–22997 (Final Rule issued July 9, 2008, amendment numbers 25–125, 26– 2, 121–340, 125–55, and 129–46): • Cargo operations are predominately at night when outside temperatures are lower. • Cargo operators turn off packs prior to takeoff. • Cargo operators have fewer daily flights (2) compared to passenger operators (4–6). • The cost/benefit does not justify retrofit on current cargo aircraft. UPS recommends that all cargo-only airplanes currently in operation be exempt from the retrofit/installation portion of the NPRM and service bulletin. UPS is of the opinion that changing the Instructions for Continuing Airworthiness and maintenance programs to perform bonding checks will be sufficient in addressing the potential short issue in existing cargoonly airplanes. UPS does not object to new cargo-only airplanes having the hot short protector installed. We do not agree with the request to exempt cargo-only airplanes from the requirements of this AD. Although the fuel tank flammability reduction rule (mentioned previously) provides important safety improvements, it was not intended to address any specific identified unsafe conditions. Instead, that rule provides an additional layer of protection when unidentified and uncorrected fuel tank ignition sources develop. This AD, however, addresses an identified ignition source in the fuel tank system. While the factors mentioned by the operator may reduce the probability that this ignition source will actually cause a fuel tank explosion, they do not justify allowing this known ignition source to continue to exist when practical means exist to eliminate it. We have not changed the AD in this regard. Actions Since NPRM Was Issued We have reviewed Airworthiness Limitation (AWL) No. 28-AWL–22 of Subsection G of Section 9, D622N001– E:\FR\FM\24MRR1.SGM 24MRR1

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

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) 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:

    During aircraft structure fatigue tests, cracks were found in 
the wing lower skin stringers between ribs 7 and 10 on both wings. 
In order to prevent fatigue cracks in the wing lower skin stringers, 
which could result in fuel leakage and reduced structural integrity 
of the wing, the referred stringers must be reworked.

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

DATES: This AD becomes effective April 28, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 28, 
2009.

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 June 24, 2008 (73 FR 
35597). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:


[[Page 12234]]


    During aircraft structure fatigue tests, cracks were found in 
the wing lower skin stringers between ribs 7 and 10 on both wings. 
In order to prevent fatigue cracks in the wing lower skin stringers, 
which could result in fuel leakage and reduced structural integrity 
of the wing, the referred stringers must be reworked.

The corrective actions include spot-facing the lower wing stringers 
between ribs 7 and 10, doing a dye-penetrant inspection of the reworked 
stringers, shot-or flap-peening if no cracking is found, contacting the 
Manager, International Branch, ANM-116, Transport Airplane Directorate, 
FAA; or the Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil 
(ANAC) (or its delegated agent) if any crack is found, and repairing.

Comments

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

Request To Include New Revision of Service Bulletin and New Inspection 
Option

    EMBRAER states that it has issued EMBRAER Service Bulletin 190-57-
0005, Revision 02, dated May 27, 2008. (We referred to EMBRAER Service 
Bulletin 190-57-0005, Revision 01, dated October 27, 2006, as the 
appropriate source of service information in the NPRM.) EMBRAER states 
that EMBRAER Service Bulletin 190-57-0005, Revision 02, dated May 27, 
2008, provides procedures for an eddy current inspection rather than 
the dye-penetrant inspection method specified in EMBRAER Service 
Bulletin 190-57-0005, Revision 01, dated October 27, 2006. The eddy 
current inspection method uses equipment that is more appropriate for 
handling inside the fuel tank. EMBRAER states that airplanes already 
inspected using the dye-penetrant inspection method do not require 
additional inspection, and requests that EMBRAER Service Bulletin 190-
57-0005, Revision 01, dated October 27, 2006, be considered an 
alternative method for complying with the NPRM.
    We agree that the eddy current inspection method specified in 
EMBRAER Service Bulletin 190-57-0005, Revision 02, dated May 27, 2008, 
is an acceptable optional way to do the inspection for cracking of the 
reworked stringers. Therefore, we have revised paragraph (f) of this AD 
to specify that operators may accomplish either the dye-penetrant 
inspection in accordance with EMBRAER Service Bulletin 190-57-0005, 
Revision 01, dated October 27, 2006, or the eddy current inspection in 
accordance with EMBRAER Service Bulletin 190-57-0005, Revision 02, 
dated May 27, 2008.

Request To Change Shot-Peening to Flap-Peening

    EMBRAER states that paragraph (f)(2)(i) of the NPRM should specify 
flap-peening of the reworked stringers if no cracking is found, rather 
than shot-peening as is specified in the NPRM. EMBRAER states that 
EMBRAER Service Bulletin 190-57-0005, Revision 02, dated May 27, 2008, 
specifies flap peening rather than shot peening.
    We partially agree. We agree with the request to specify flap-
peening in paragraph (f)(2)(i) of the AD; however, we disagree with 
specifying only flap peening in that paragraph because shot-peening is 
also an acceptable method of compliance. Airplanes that are in 
compliance with EMBRAER Service Bulletin 190-57-0005, Revision 01, 
dated October 27, 2006, do not need additional action. We have revised 
paragraph (f)(2)(i) of this AD to specify that both shot peening and 
flap peening are acceptable methods of compliance.

Request To Revise Contact for Repair Information

    EMBRAER requests that we revise paragraph (f)(2)(ii) of the NPRM to 
specify that operators may contact not only Ag[ecirc]ncia Nacional de 
Avia[ccedil][atilde]o Civil (ANAC) for repair instructions if cracking 
is found, but also its delegated agent, or the Manager of the FAA's 
Transport Airplane Directorate (TAD).
    We agree that contacting one of ANAC's delegated agents or the TAD 
is appropriate. Therefore, we have changed paragraphs (e) and 
(f)(2)(ii) of this AD, and the last paragraph of the ``Discussion'' 
section, to specify that operators may also contact a delegated agent 
of ANAC, or the Manager of the TAD for repair instructions.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously. We determined that these 
changes 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 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 highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 18 products of U.S. registry. 
We also estimate that it will take 110 work-hours per product to comply 
with the basic requirements of this AD. The average labor rate is $80 
per work-hour. Based on these figures, we estimate the cost of this AD 
to the U.S. operators to be $158,400 or $8,800 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 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.

[[Page 12235]]

    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, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.
