Download as PDF 21246 Federal Register / Vol. 74, No. 87 / Thursday, May 7, 2009 / Rules and Regulations change on which to seek public input, the Board has determined that the § 553(b) notice and comment procedures are unnecessary. In addition, the underlying consolidation of Federal Reserve Bank check-processing offices involves a matter relating to agency management, which is exempt from notice and comment procedures. Paperwork Reduction Act In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3506; 5 CFR 1320 Appendix A.1), the Board has reviewed the final rule under authority delegated to the Board by the Office of Management and Budget. The technical amendments to appendix A of Regulation CC will (i) delete the reference to the Seattle branch office of the Federal Reserve Bank of San Francisco and reassign the routing symbols listed under that office to the Los Angeles branch office of the Federal Reserve Bank of San Francisco, and (ii) delete the reference to the Denver branch office of the Federal Reserve Bank of Kansas City and reassign the routing symbols listed under that office to the Los Angeles branch office of the Federal Reserve Bank of San Francisco and to the head office of the Federal Reserve Bank of Dallas. The depository institutions that are located in the affected check-processing regions and that include the routing numbers in their disclosure statements would be required to notify customers of the resulting change in availability under § 229.18(e). However, all paperwork collection procedures associated with Regulation CC already are in place, and the Board accordingly anticipates that no additional burden will be imposed as a result of this rulemaking.

ACTION: Final rule. SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. That AD currently requires operators to determine the number of flight cycles accumulated on each component of the main landing gear (MLG) and the nose landing gear (NLG), and to replace each component that reaches its life limit with a serviceable component. The existing AD also requires operators to revise the Airworthiness Limitations (AWL) section of the Instructions for Continued Airworthiness (ICA) in the aircraft maintenance manual to reflect the new life limits for structurally significant items. This new AD requires a new revision of the AWL section of the ICA to incorporate revised life limits for structurally significant items, E:\FR\FM\07MYR1.SGM 07MYR1 21247 Federal Register / Vol. 74, No. 87 / Thursday, May 7, 2009 / Rules and Regulations operational and functional tests of certain systems, and instructions to retain critical ignition source prevention features during configuration changes. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. We are issuing this AD to prevent failure of certain structurally significant items, including the MLG and the NLG, which could result in reduced structural integrity of the airplane; and to prevent fuel vapor ignition sources, which could result in fuel tank explosion and consequent loss of the airplane. DATES: This AD becomes effective June 11, 2009. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of June 11, 2009. The Director of the Federal Register approved the incorporation by reference of certain other publications as of October 26, 2005 (70 FR 55230, September 21, 2005).

SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 2005–19–15, amendment 39–14280 (70 FR 55230, September 21, 2005). The existing AD applies to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. That NPRM was published in the Federal Register on November 17, 2008 (73 FR 67817). That NPRM proposed to continue to require operators to determine the number of flight cycles accumulated on each component of the main landing gear and the nose landing gear, and to replace each component that reaches its life limit with a serviceable component. That NPRM also proposed to continue to require operators to revise the Airworthiness Limitations (AWL) section of the Instructions for Continued Airworthiness (ICA) in the aircraft maintenance manual to reflect the new life limits for structurally significant items. That NPRM also proposed to require a new revision of the AWL section of the ICA to incorporate revised life limits for structurally significant items, operational and functional tests of certain systems, and instructions to retain critical ignition source prevention features during configuration changes. Comments We provided the public the opportunity to participate in the development of this AD. No comments have been received on the NPRM or on the determination of the cost to the public. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this AD. ESTIMATED COSTS Action AWL revision (required by AD 2005–19–15) ....................... AWL revision (new action) ................................................... 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 VerDate Nov<24>2008 16:03 May 06, 2009 Average labor rate per hour Work hour Jkt 217001 1 1 $80 80 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 this AD: PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 Cost per airplane Number of U.S.-registered airplanes $80 80 3 3 Fleet cost $240 240 (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. See the ADDRESSES section for a location to examine the regulatory evaluation. E:\FR\FM\07MYR1.SGM 07MYR1 21248 Federal Register / Vol. 74, No. 87 / Thursday, May 7, 2009 / Rules and Regulations originated by an aviation authority of another country.

This AD requires repetitive external surface high frequency eddy current inspections to detect cracks in the radius detail of the upper lobe doubler on both sides of the airplane, and applicable corrective action. This AD results from reports of cracks in the radius detail of the upper lobe doublers. We are issuing this AD to detect and correct cracks in the upper lobe doublers. Such cracks could result in significant degradation of the fuselage structure and reduce its ability to carry flight loads from the vertical stabilizer, which could adversely affect the controllability of the airplane.

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to all BAE Systems (Operations) Limited (Jetstream) 
Model 4101 airplanes. That AD currently requires operators to determine 
the number of flight cycles accumulated on each component of the main 
landing gear (MLG) and the nose landing gear (NLG), and to replace each 
component that reaches its life limit with a serviceable component. The 
existing AD also requires operators to revise the Airworthiness 
Limitations (AWL) section of the Instructions for Continued 
Airworthiness (ICA) in the aircraft maintenance manual to reflect the 
new life limits for structurally significant items. This new AD 
requires a new revision of the AWL section of the ICA to incorporate 
revised life limits for structurally significant items,

[[Page 21247]]

operational and functional tests of certain systems, and instructions 
to retain critical ignition source prevention features during 
configuration changes. This AD results from mandatory continuing 
airworthiness information (MCAI) originated by an aviation authority of 
another country. We are issuing this AD to prevent failure of certain 
structurally significant items, including the MLG and the NLG, which 
could result in reduced structural integrity of the airplane; and to 
prevent fuel vapor ignition sources, which could result in fuel tank 
explosion and consequent loss of the airplane.

DATES: This AD becomes effective June 11, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of June 11, 
2009.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2005-19-15, amendment 
39-14280 (70 FR 55230, September 21, 2005). The existing AD applies to 
all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. 
That NPRM was published in the Federal Register on November 17, 2008 
(73 FR 67817). That NPRM proposed to continue to require operators to 
determine the number of flight cycles accumulated on each component of 
the main landing gear and the nose landing gear, and to replace each 
component that reaches its life limit with a serviceable component. 
That NPRM also proposed to continue to require operators to revise the 
Airworthiness Limitations (AWL) section of the Instructions for 
Continued Airworthiness (ICA) in the aircraft maintenance manual to 
reflect the new life limits for structurally significant items. That 
NPRM also proposed to require a new revision of the AWL section of the 
ICA to incorporate revised life limits for structurally significant 
items, operational and functional tests of certain systems, and 
instructions to retain critical ignition source prevention features 
during configuration changes.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the NPRM or 
on the determination of the cost to the public.

Conclusion

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

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this AD.

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 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

0
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 Federal Aviation Administration (FAA) amends Sec.  39.13 by 
removing amendment 39-14280 (70 FR 55230, September 21, 2005) and by 
adding the following new airworthiness directive (AD):

2009-10-02 BAE Systems (Operations) Limited (Formerly British 
Aerospace Regional Aircraft): Amendment 39-15897. Docket No. FAA-
2008-1214; Directorate Identifier 2007-NM-259-AD.

Effective Date

    (a) This AD becomes effective June 11, 2009.

Affected ADs

    (b) This AD supersedes AD 2005-19-15.

Applicability

    (c) This AD applies to all BAE Systems (Operations) Limited 
Model Jetstream 4101 airplanes, certificated in any category.

Unsafe Condition

    (d) This AD results from mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country. We are issuing this AD to prevent failure of certain 
structurally significant items, including the main landing gear and 
the nose landing gear, which could result in reduced structural 
integrity of the airplane; and to prevent fuel vapor ignition 
sources, which could result in fuel tank explosion and consequent 
loss of the airplane.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Certain Requirement of AD 2005-19-15: Revise Aircraft Maintenance 
Manual (AMM)

    (f) Within 30 days after October 26, 2005 (the effective date of 
AD 2005-19-15): Revise the Airworthiness Limitations (AWL) section 
of the Instructions for Continued Airworthiness of the BAE Systems 
(Operations) Limited J41 AMM to include the life limits of the 
components listed in Chapter 05-10-10, Airworthiness Limitations--
Description and Operation Section, Revision 23, dated February 15, 
2005, of the AMM. This may be accomplished by inserting a copy into 
the AWL section of the Instructions for Continued Airworthiness. 
Thereafter, except as provided in paragraph (i) of this AD, no 
alternative replacement times may be approved for any affected 
component.

New Requirements of This AD: Revise AWL Section of Instructions for 
Continued Airworthiness

    (g) Within 90 days after the effective date of this AD: Revise 
the AWL section of the Instructions for Continued Airworthiness by 
incorporating the instructions of Subjects 05-10-10, ``Airworthiness 
Limitations,'' 05-10-20, ``Certification Maintenance Requirements,'' 
and 05-10-30, ``Critical Design Configuration Control Limitations 
(CDCCL)--Fuel System'' of the BAE Systems (Operations) Limited 
Jetstream Series 4100 AMM, Revision 31, dated February 15, 2009. 
Thereafter, except as provided in paragraph (i) of this AD, no 
alternative replacement times or inspection intervals may be 
approved for any affected component. The revised Chapter 05-10-10 
replaces the corresponding chapter specified in paragraph (f) of 
this AD.
    (h) Where paragraph 2.A.(2) of Subject 05-10-10 of the BAE 
Systems (Operations) Limited Jetstream Series 4100 AMM, Revision 31, 
dated February 15, 2009, specifies that certain landing gear units 
``must be removed before 31st March 2008,'' this AD requires 
compliance within 60 days after the effective date of this AD.

Alternative Methods of Compliance (AMOCs)

    (i) The Manager, International Branch, ANM-116, Transport 
Airplane Directorate, FAA, has the authority to approve AMOCs for 
this AD, if requested using the procedures found in 14 CFR 39.19. 
Send information to ATTN: Todd Thompson, Aerospace Engineer, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone 
(425) 227-1175; fax (425) 227-1149. Before using any approved AMOC 
on any airplane to which the AMOC applies, notify your appropriate 
principal inspector (PI) in the FAA Flight Standards District Office 
(FSDO), or lacking a PI, your local FSDO.
