The agencies expect that this joint final rule will not have significant secondary or incidental effects on a substantial number of small entities or create any additional burden on small entities. This joint final rule merely confirms that the joint interim rule, which made a technical correction and conformed terminology in the current CRA regulations to terms and definitions already adopted by OMB, Census, and the Board, is final. Accordingly, a regulatory flexibility analysis is not required. OCC Executive Order 13132 Determination The OCC has determined that this joint final rule does not have any Federalism implications, as required by Executive Order 13132. is adopted as a joint final rule without change. List of Subjects PART 563e—COMMUNITY REINVESTMENT OCC and OTS Executive Order 12866 Determinations 12 CFR Part 345 Banks, Banking, Community development, Credit, Investments, Reporting and recordkeeping requirements. The OCC and the OTS have determined that this joint final rule is not a significant regulatory action as defined in Executive Order 12866. OCC and OTS Unfunded Mandates Reform Act of 1995 Determinations Section 202 of the Unfunded Mandates Reform Act of 1995 (Unfunded Mandates Act) (2 U.S.C. 1532) requires that covered agencies prepare a budgetary impact statement before promulgating a rule that includes any Federal mandate that may result in the expenditure by State, local, and tribal governments, in the aggregate, or by the private sector, of $100 million or more in any one year. If a budgetary impact statement is required, section 205 of the Unfunded Mandates Act also requires covered agencies to identify and consider a reasonable number of regulatory alternatives before promulgating a rule. The OCC and OTS have determined that this joint final rule will not result in expenditures by State, local, and tribal governments, or by the private sector, of $100 million or more in any one year. Accordingly, neither agency has prepared a budgetary impact statement or specifically addressed the regulatory alternatives considered. The Treasury and General Government Appropriations Act, 1999—Assessment of Impact of Federal Regulation on Families The FDIC has determined that this joint final rule will not affect family well-being within the meaning of section 654 of the Treasury and General Government Appropriations Act, enacted as part of the Omnibus Consolidated and Emergency Supplemental Appropriations Act of 1999, Public Law 105–277 (5 U.S.C. 601 note).

FOR FURTHER INFORMATION CONTACT: Todd Thompson, Aerospace Engineer, International Branch, ANM–116, FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington 98055–4056; telephone (425) 227–1175; fax (425) 227–1149. SUPPLEMENTARY INFORMATION: The FAA proposed to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) with an AD to supersede AD 99–17–12, amendment 39–11260 (64 FR 45870, August 23, 1999). The existing AD applies to certain British Aerospace Model BAe 146 and Model Avro 146– RJ series airplanes. The proposed AD was published in the Federal Register on December 1, 2004 (69 FR 69829), to require a one-time measurement of the thickness of the outer links on the side stays of the main landing gear (MLG), and related investigative and corrective actions as necessary; and provides for replacement of a thin outer link with a new or serviceable part in lieu of certain related investigative inspections. The proposed AD also expanded the applicability of the existing AD, provided for optional terminating action for the repetitive inspections, and reduced the repetitive inspection interval. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comment that has been submitted on the proposed AD. Request To Correct Typographical Error in Preamble The commenter recommends the correction of a typographical error that appears in the Secondary Service Information table in the proposed AD. (That table is included in the Relevant Service Information section of the preamble of the proposed AD). The commenter notes that one of the column headers references BAE Systems (Operations) Limited Inspection Service Bulletin ISB.32–1536, but that the correct citation is ISB.32–156. The commenter suggests correcting the 15575 typographical error to eliminate any confusion to anyone who reads the proposed AD. We agree with the commenter’s concern and acknowledge that the typographical error did appear in the published versions of the proposed AD. The Secondary Service Information table is not restated in this AD, so no change is possible regarding this issue. Changes to This AD In order to comply with the service information citation guidelines of the Office of the Federal Register, we have revised Notes 2 and 3 of this AD. In Note 2 we changed the citation from ‘‘BAE Inspection Service Bulletin ISB.32–156’’ to ‘‘BAE Systems (Operations) Limited Inspection Service Bulletin ISB.32–156, Revision 1, dated July 3, 2001.’’ In Note 3 we made that same change; revised ‘‘32–162– 70657CD’’ to ‘‘SB.32–162–70657C.D;’’ clarified that Messier-Dowty Repair Scheme 450187952 is included in Section 32–10–65 of the Messier-Dowty 201105001 and 201105002 Component Maintenance Manual, and Section 32– 10–73 of the Messier-Dowty 201299001 and 201299002 Component Maintenance Manual; and corrected the manufacturer name and document number for SB.32–144. Conclusion We have carefully reviewed the available data, including the comment that has been submitted, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this proposed AD. ESTIMATED COSTS Action Work hours Average hourly labor rate 1 $65 Inspection ....................... 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, VerDate jul<14>2003 15:00 Mar 25, 2005 Jkt 205001 Parts Cost per airplane None .......... $65, per inspection cycle 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, PO 00000 Number of U.S.-registered airplanes Frm 00023 Fmt 4700 Sfmt 4700 60 Fleet cost $3,900, per inspection cycle. ‘‘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 E:\FR\FM\28MRR1.SGM 28MRR1 15576 Federal Register / Vol. 70, No. 58 / Monday, March 28, 2005 / Rules and Regulations 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. See the ADDRESSES section for a location to examine the regulatory evaluation.

Investigation revealed that most of the rudder, including the front spar portion above the three servo control actuators was missing. The cause of this rudder loss is under investigation. This condition, if not corrected, could result in detachment of the rudder from the airplane, which could degrade airplane handling qualities and result in reduced controllability of the airplane. Examining the Docket Airbus has issued All Operators Telex (AOT) A310A55–2035 (for A310 series airplanes) and AOT A300–600 55A6035 (for A300–600 series airplanes), both dated March 16, 2005. The AOTs describe procedures for one-time general visual, detailed visual, and tap test inspections for damage in the structural integrity of the rudder and its attachments. The inspection procedures include a general visual inspection for damage of the rear spar aft face of the vertical stabilizer, including the trailing edge structure; a detailed visual inspection of the rudder hinge arms and support fittings, the actuator support fittings and the rudder hinge fittings; and a tap test inspection for damage of the rudder side panels of the leading edge from the bottom to top and the forward trailing edge connection from the bottom up to hinge No. 5 around the hoisting points and certain additional areas. The AOTs also specify contacting the manufacturer for certain repair conditions and reporting of inspection results.

Airworthiness Directives; British Aerospace Model BAe 146 and 
Model Avro 146-RJ Series Airplanes

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 certain British Aerospace Model BAe 146 and 
Model Avro 146-RJ series airplanes. That AD currently requires a one-
time measurement of the thickness of the outer links on the side stays 
of the main landing gear (MLG), and related investigative and 
corrective actions as necessary; and provides for replacement of a thin 
outer link with a new or

[[Page 15575]]

serviceable part in lieu of certain related investigative inspections. 
This new AD requires repetitive inspections for cracking of the outer 
links on the MLG side stays, and corrective actions if necessary. This 
new action also expands the applicability, provides for optional 
terminating action for the repetitive inspections, and reduces the 
repetitive inspection interval. This AD is prompted by new crack 
findings on airplanes not subject to the existing AD, and the 
determination that the profile gauge's slipping over the outer link 
profile is not a factor in the identified unsafe condition. We are 
issuing this AD to prevent cracking of the outer links of the MLG side 
stays, which could result in failure of a side stay and consequent 
collapse of the landing gear.

DATES: This AD becomes effective May 2, 2005.
    The incorporation by reference of a certain publication listed in 
the AD is approved by the Director of the Federal Register as of May 2, 
2005.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend part 39 of the 
Federal Aviation Regulations (14 CFR part 39) with an AD to supersede 
AD 99-17-12, amendment 39-11260 (64 FR 45870, August 23, 1999). The 
existing AD applies to certain British Aerospace Model BAe 146 and 
Model Avro 146-RJ series airplanes. The proposed AD was published in 
the Federal Register on December 1, 2004 (69 FR 69829), to require a 
one-time measurement of the thickness of the outer links on the side 
stays of the main landing gear (MLG), and related investigative and 
corrective actions as necessary; and provides for replacement of a thin 
outer link with a new or serviceable part in lieu of certain related 
investigative inspections. The proposed AD also expanded the 
applicability of the existing AD, provided for optional terminating 
action for the repetitive inspections, and reduced the repetitive 
inspection interval.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment that has been 
submitted on the proposed AD.

Request To Correct Typographical Error in Preamble

    The commenter recommends the correction of a typographical error 
that appears in the Secondary Service Information table in the proposed 
AD. (That table is included in the Relevant Service Information section 
of the preamble of the proposed AD). The commenter notes that one of 
the column headers references BAE Systems (Operations) Limited 
Inspection Service Bulletin ISB.32-1536, but that the correct citation 
is ISB.32-156. The commenter suggests correcting the typographical 
error to eliminate any confusion to anyone who reads the proposed AD.
    We agree with the commenter's concern and acknowledge that the 
typographical error did appear in the published versions of the 
proposed AD. The Secondary Service Information table is not restated in 
this AD, so no change is possible regarding this issue.

Changes to This AD

    In order to comply with the service information citation guidelines 
of the Office of the Federal Register, we have revised Notes 2 and 3 of 
this AD. In Note 2 we changed the citation from ``BAE Inspection 
Service Bulletin ISB.32-156'' to ``BAE Systems (Operations) Limited 
Inspection Service Bulletin ISB.32-156, Revision 1, dated July 3, 
2001.'' In Note 3 we made that same change; revised ``32-162-70657CD'' 
to ``SB.32-162-70657C.D;'' clarified that Messier-Dowty Repair Scheme 
450187952 is included in Section 32-10-65 of the Messier-Dowty 
201105001 and 201105002 Component Maintenance Manual, and Section 32-
10-73 of the Messier-Dowty 201299001 and 201299002 Component 
Maintenance Manual; and corrected the manufacturer name and document 
number for SB.32-144.

Conclusion

    We have carefully reviewed the available data, including the 
comment that has been submitted, and determined that air safety and the 
public interest require adopting the AD with the changes described 
previously. We have determined that these changes will neither increase 
the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

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

[[Page 15576]]

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. 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 FAA amends Sec.  39.13 by removing amendment 39-11260 (64 FR 
45870, August 23, 1999), and by adding the following new airworthiness 
directive (AD):

2005-06-04 BAE Systems (Operations) Limited (Formerly British 
Aerospace Regional Aircraft): Amendment 39-14024. Docket No. FAA-
2004-19757; Directorate Identifier 2001-NM-273-AD.

Effective Date

    (a) This AD becomes effective May 2, 2005.

Affected ADs

    (b) This AD supersedes AD 99-17-12, amendment 39-11260 (64 FR 
45870, August 23, 1999).

Applicability

    (c) This AD applies to Model BAe 146 and Avro 146-RJ series 
airplanes, certificated in any category, having any side stay 
identified in Messier-Dowty Service Bulletin 146-32-147, dated May 
29, 2001.

Unsafe Condition

    (d) This AD was prompted by new crack findings on airplanes not 
subject to the existing AD, and the determination that the profile 
gauge's slipping over the outer link profile is not a factor in the 
identified unsafe condition. We are issuing this AD to prevent 
cracking of the outer links of the MLG side stays, which could 
result in failure of a side stay and consequent collapse of the 
landing gear.

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.

Inspection

    (f) At the applicable time specified in paragraph (f)(1) or 
(f)(2) of this AD: Perform a detailed inspection for cracks of the 
outer links on the MLG side stays, in accordance with the 
Accomplishment Instructions of BAE Systems (Operations) Limited 
Inspection Service Bulletin ISB.32-156, Revision 1, dated July 3, 
2001. Repair cracks before further flight in accordance with the 
service bulletin. Thereafter, repeat the inspection at intervals not 
to exceed 2,000 flight cycles, until the actions specified in 
paragraph (g) of this AD have been done. Although the service 
bulletin specifies to report certain information to the 
manufacturer, this AD does not require a report.
    (1) If the number of flight cycles accumulated on the side stay 
can be positively determined: Inspect before the accumulation of 
2,000 total flight cycles on the side stay, or within 500 flight 
cycles after the effective date of this AD, whichever occurs later.
    (2) If the number of flight cycles accumulated on the side stay 
cannot be positively determined: Inspect within 500 flight cycles 
after the effective date of this AD.

    Note 1: For the purposes of this AD, a detailed inspection is: 
``An intensive examination of a specific item, installation, or 
assembly to detect damage, failure, or irregularity. Available 
lighting is normally supplemented with a direct source of good 
lighting at an intensity deemed appropriate. Inspection aids such as 
mirror, magnifying lenses, etc., may be necessary. Surface cleaning 
and elaborate procedures may be required.''


    Note 2: BAE Systems (Operations) Limited Inspection Service 
Bulletin ISB.32-156, Revision 1, dated July 3, 2001, refers to 
Messier-Dowty Service Bulletin 146-32-147, dated May 29, 2001, as an 
additional source of service information for the inspection.

Optional Terminating Action

    (g) Relocation of each affected grease nipple to the upper 
surface of the outer link of the MLG side stays terminates the 
repetitive inspection requirements of this AD, if the relocation 
action is done in accordance with paragraph 2.C. of the 
Accomplishment Instructions of BAE Systems (Operations) Limited 
Inspection Service Bulletin ISB.32-156, Revision 1, dated July 3, 
2001.

    Note 3: BAE Systems (Operations) Limited Inspection Service 
Bulletin ISB.32-156, Revision 1, dated July 3, 2001; refers to BAE 
Systems (Operations) Limited Modification Service Bulletin SB.32-
162-70657C.D, dated September 26, 2001; Messier-Dowty Repair Scheme 
450187952, included in Section 32-10-65 of the Messier-Dowty 
201105001 and 201105002 Component Maintenance Manual, and Section 
32-10-73 of the Messier-Dowty 201299001 and 201299002 Component 
Maintenance Manual; and British Aerospace Service Bulletin SB.32-
144, dated December 11, 1996; as additional sources of service 
information for accomplishment of the actions associated with the 
relocation specified in paragraph (g) of this AD.

Parts Installation

    (h) As of the effective date of this AD, no person may install 
on any airplane an MLG side stay having a part number identified in 
paragraph 1.A. of Messier-Dowty Service Bulletin 146-32-147, dated 
May 29, 2001, unless that part has been inspected and all applicable 
related investigative and corrective actions have been performed in 
accordance with the requirements 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 in accordance with the procedures found in 14 
CFR 39.19.

Related Information

    (j) British airworthiness directive 004-05-2001 also addresses 
the subject of this AD.
