ACTION: Final rule. AGENCY: cprice-sewell on DSKDVH8Z91PROD with RULES 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: The airbrake upper crossbeam on an airplane failed in-flight. The crossbeam failure caused damage to the rudder control system, resulting in loss of rudder control. Loss of rudder control will cause handling difficulties particularly during take-off, approach, and landing phases in cross winds. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products. VerDate Nov<24>2008 14:34 Aug 17, 2009 Jkt 217001 41605 DATES: This AD becomes effective September 22, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of September 22, 2009. ADDRESSES: You may examine the AD docket on the Internet at http:// 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: The required actions include replacing the three rivets with Hi-lok pins. For cracking, damage, or discontinuity that is outside certain limits defined in the service bulletin, the repair includes contacting BAE Systems (Operations) Limited for repair instructions and doing the repair. You may obtain further information by examining the MCAI in the AD docket. Discussion Differences Between This AD and the MCAI or Service Information 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 11, 2009 (74 FR 27725). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: The airbrake upper crossbeam on an airplane failed in-flight. The crossbeam failure caused damage to the rudder control system, resulting in loss of rudder control. Loss of rudder control will cause handling difficulties particularly during take-off, approach, and landing phases in cross winds. BAE Systems (Operations) Ltd has published Inspection Service Bulletin (ISB) 53–200 that revises and supersedes the inspection requirements, which are defined in the Maintenance Review Board Report (MRBR) SSI Task 53–40–125, Supplemental Structural Inspections Document (SSID) Tasks 53–40–125.1 and 53–40–125.2 (included in the Airworthiness Limitations Section of Aircraft Maintenance Manual Chapter 5 that is currently mandated as part of EASA AD 2007–0271 [which corresponds to an FAA NPRM, Directorate Identifier 2007–NM–363–AD]) and in Maintenance Planning Document (MPD) Task Reference 534025–DVI–10000–1. These revised inspection requirements and reduced inspection periods are to ensure that any fatigue damage is detected before it causes upper airbrake crossbeam failure. MRBR, SSID and MPD will be amended in due course to reflect these revised inspection periods. For the reasons stated above, this Airworthiness Directive (AD) requires the [high frequency eddy current and low frequency phase analysis eddy current] inspection [for cracking, discrete surface damage, and discontinuity (corrosion and mechanical damage)] and, as necessary, repair of the airbrake upper crossbeam. PO 00000 Frm 00025 Fmt 4700 Sfmt 4700 Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. 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 affects 1 product of U.S. registry. We also estimate that it takes about 6 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 $480 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 E:\FR\FM\18AUR1.SGM 18AUR1 41606 Federal Register / Vol. 74, No. 158 / Tuesday, August 18, 2009 / Rules and Regulations 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. § 39.13 Regulatory Findings Effective Date 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. 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 http:// 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.

Docket No. FAA–2009–0532; Directorate Identifier 2008–NM–024–AD. (a) This airworthiness directive (AD) becomes effective September 22, 2009. Affected ADs (b) None. Applicability (c) This AD applies to all BAE Systems (Operations) Limited Model BAe 146 and Avro 146–RJ airplanes, certificated in any category. Subject (d) Air Transport Association (ATA) of America Code 53: Fuselage. Reason (e) The mandatory continuing airworthiness information (MCAI) states: The airbrake upper crossbeam on an airplane failed in-flight. The crossbeam failure caused damage to the rudder control system, resulting in loss of rudder control. Loss of rudder control will cause handling difficulties particularly during take-off, approach, and landing phases in cross winds. BAE Systems (Operations) Ltd has published Inspection Service Bulletin (ISB) 53–200 that revises and supersedes the inspection requirements, which are defined in the Maintenance Review Board Report (MRBR) SSI Task 53–40–125, Supplemental Structural Inspections Document (SSID) Tasks 53–40–125.1 and 53–40–125.2 (included in the Airworthiness Limitations Section of Aircraft Maintenance Manual Chapter 5 that is currently mandated as part of EASA AD 2007–0271 [which corresponds to an FAA NPRM, Directorate Identifier 2007–NM–363–AD]) and in Maintenance Planning Document (MPD) Task Reference 534025–DVI–10000–1. These revised inspection requirements and reduced inspection periods are to ensure that any fatigue damage is detected before it causes upper airbrake crossbeam failure. MRBR, SSID and MPD will be amended in due course to reflect these revised inspection periods. For the reasons stated above, this Airworthiness Directive (AD) requires the [high frequency eddy current and a low frequency phase analysis eddy current] inspection [for cracking, discrete surface damage, and discontinuity (corrosion and mechanical damage)] and, as necessary, repair of the airbrake upper crossbeam. The required actions include replacing the three rivets with Hi-lok pins.

ACTION: Final rule. SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 737–600, –700, –700C, –800, and –900 series airplanes. That AD currently requires replacing brackets that hold the P5 panel to the airplane structure, the standby compass bracket assembly, the generator drive and standby power module, and the air conditioning module, as applicable. The existing AD also currently requires, among other actions, inspecting for wire length and for damage of the connectors and the wire bundles, and doing applicable corrective actions if necessary. This new AD requires an additional operational test of the P5–14 panel. This AD results from a report of an electrical burning smell in the flight compartment. We are issuing this AD to prevent wire bundles from contacting the overhead dripshield panel and modules in the P5 overhead panel, which could result in electrical arcing and shorting of the electrical connector and consequent loss of several critical systems essential for safe flight; and to ensure proper operation of the passenger oxygen system. If an improperly functioning passenger PO 00000 Frm 00027 Fmt 4700 Sfmt 4700 41607 oxygen system goes undetected, the passenger oxygen mask could fail to deploy and result in possible incapacitation of passengers during a depressurization event.

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:

    The airbrake upper crossbeam on an airplane failed in-flight. 
The crossbeam failure caused damage to the rudder control system, 
resulting in loss of rudder control. Loss of rudder control will 
cause handling difficulties particularly during take-off, approach, 
and landing phases in cross winds.
* * * * *
    We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective September 22, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 22, 
2009.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of

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 11, 2009 (74 FR 
27725). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    The airbrake upper crossbeam on an airplane failed in-flight. 
The crossbeam failure caused damage to the rudder control system, 
resulting in loss of rudder control. Loss of rudder control will 
cause handling difficulties particularly during take-off, approach, 
and landing phases in cross winds.
    BAE Systems (Operations) Ltd has published Inspection Service 
Bulletin (ISB) 53-200 that revises and supersedes the inspection 
requirements, which are defined in the Maintenance Review Board 
Report (MRBR) SSI Task 53-40-125, Supplemental Structural 
Inspections Document (SSID) Tasks 53-40-125.1 and 53-40-125.2 
(included in the Airworthiness Limitations Section of Aircraft 
Maintenance Manual Chapter 5 that is currently mandated as part of 
EASA AD 2007-0271 [which corresponds to an FAA NPRM, Directorate 
Identifier 2007-NM-363-AD]) and in Maintenance Planning Document 
(MPD) Task Reference 534025-DVI-10000-1. These revised inspection 
requirements and reduced inspection periods are to ensure that any 
fatigue damage is detected before it causes upper airbrake crossbeam 
failure. MRBR, SSID and MPD will be amended in due course to reflect 
these revised inspection periods.
    For the reasons stated above, this Airworthiness Directive (AD) 
requires the [high frequency eddy current and low frequency phase 
analysis eddy current] inspection [for cracking, discrete surface 
damage, and discontinuity (corrosion and mechanical damage)] and, as 
necessary, repair of the airbrake upper crossbeam.

    The required actions include replacing the three rivets with Hi-lok 
pins. For cracking, damage, or discontinuity that is outside certain 
limits defined in the service bulletin, the repair includes contacting 
BAE Systems (Operations) Limited for repair instructions and doing the 
repair. You may obtain further information by examining the MCAI in the 
AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

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

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 affects 1 product of U.S. registry. We 
also estimate that it takes about 6 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 $480 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

[[Page 41606]]

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;

Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

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 adding the following new AD:

2009-17-03 BAE Systems (Operations) Limited (Formerly British 
Aerospace Regional Aircraft): Amendment 39-15994. Docket No. FAA-
2009-0532; Directorate Identifier 2008-NM-024-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective 
September 22, 2009.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to all BAE Systems (Operations) Limited 
Model BAe 146 and Avro 146-RJ airplanes, certificated in any 
category.

Subject

    (d) Air Transport Association (ATA) of America Code 53: 
Fuselage.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    The airbrake upper crossbeam on an airplane failed in-flight. 
The crossbeam failure caused damage to the rudder control system, 
resulting in loss of rudder control. Loss of rudder control will 
cause handling difficulties particularly during take-off, approach, 
and landing phases in cross winds.
    BAE Systems (Operations) Ltd has published Inspection Service 
Bulletin (ISB) 53-200 that revises and supersedes the inspection 
requirements, which are defined in the Maintenance Review Board 
Report (MRBR) SSI Task 53-40-125, Supplemental Structural 
Inspections Document (SSID) Tasks 53-40-125.1 and 53-40-125.2 
(included in the Airworthiness Limitations Section of Aircraft 
Maintenance Manual Chapter 5 that is currently mandated as part of 
EASA AD 2007-0271 [which corresponds to an FAA NPRM, Directorate 
Identifier 2007-NM-363-AD]) and in Maintenance Planning Document 
(MPD) Task Reference 534025-DVI-10000-1. These revised inspection 
requirements and reduced inspection periods are to ensure that any 
fatigue damage is detected before it causes upper airbrake crossbeam 
failure. MRBR, SSID and MPD will be amended in due course to reflect 
these revised inspection periods.
    For the reasons stated above, this Airworthiness Directive (AD) 
requires the [high frequency eddy current and a low frequency phase 
analysis eddy current] inspection [for cracking, discrete surface 
damage, and discontinuity (corrosion and mechanical damage)] and, as 
necessary, repair of the airbrake upper crossbeam.
    The required actions include replacing the three rivets with Hi-
lok pins. For cracking, damage, or discontinuity that is outside 
certain limits defined in the service bulletin, the repair includes 
contacting BAE Systems (Operations) Limited for repair instructions 
and doing the repair.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) At the applicable time specified in paragraphs (f)(1)(i) and 
(f)(1)(ii) of this AD, inspect for cracking, damage, and 
discontinuity of the airbrake upper crossbeam fastener positions and 
lightening holes; and replace the three rivets with Hi-lok pins; in 
accordance with paragraphs 2.B., 2.C., and 2.D. of the 
Accomplishment Instructions of BAE Systems (Operations) Limited 
Inspection Service Bulletin ISB.53-200, Revision 1, dated March 13, 
2007. If any crack, damage, or discontinuity is found: Before 
further flight, repair as required by paragraph (f)(3) of this AD.
    (i) For airplanes that have not been inspected in accordance 
with BAE Systems (Operations) Limited MRBR SSI Task No. 53-40-125 
(MPD Reference 534025-DVI-10000-1) as of the effective date of this 
AD, do the inspection prior to accumulating 20,000 total flight 
cycles or 500 flight cycles after the effective date of this AD, 
whichever occurs later.
    (ii) For airplanes subject to MRBR and SSID requirements that 
have been inspected in accordance with BAE Systems (Operations) 
Limited MRBR SSI Task No. 53-40-125 (MPD Reference 534025-DVI-10000-
1) as of the effective date of this AD, do the inspection at the 
latest of the times in paragraphs (f)(1)(ii)(A), (f)(1)(ii)(B), or 
(f)(1)(ii)(C) of this AD.
    (A) Before the accumulation of 4,000 flight cycles since last 
inspection.
    (B) Within 2,500 flight cycles (for MRBR airplanes), or within 
1,000 flight cycles (for SSID airplanes) after the effective date of 
this AD; but not exceeding 8,000 flight cycles since the last 
inspection.
    (C) Within 500 flight cycles after the effective date of this 
AD.
    (2) Repeat the inspection required by paragraph (f)(1) of this 
AD thereafter at the applicable time specified in paragraph 
(f)(2)(i), (f)(2)(ii), or (f)(2)(iii) of this AD. If any crack, 
damage, or discontinuity is found: Before further flight, repair as 
required by paragraph (f)(3) of this AD.
    (i) Inspect fastener positions at the rivet locations at 
intervals not to exceed 4,000 flight cycles.
    (ii) Inspect the holes at Hi-lok pin locations at intervals not 
to exceed 12,000 flight cycles.
    (iii) Inspect the lightening holes at intervals not to exceed 
12,000 flight cycles.
    (3) If any crack, damage, or discontinuity is found during any 
inspection required by this AD: Before further flight, do the repair 
in accordance with paragraph 2.E. of the Accomplishment Instructions 
of BAE Systems (Operations) Limited Inspection Service Bulletin 
ISB.53-200, Revision 1, dated March 13, 2007.
    (4) Actions accomplished before the effective date of this AD in 
accordance with BAE Systems (Operations) Limited Inspection Service 
Bulletin ISB.53-200, dated December 21, 2006, are considered 
acceptable for compliance with the corresponding action specified in 
this AD.
