SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above that would supersede an existing AD. 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:

    A review of the results of the final fuselage fatigue test 
identified the need for additional and revised safety-related 
fatigue- and environmental inspections for the fuselage. These 
additional tasks were introduced by Service Bulletin (SB) ATP-51-002 
* * *.
    As it was determined that these inspections were necessary to 
maintain the structural integrity of the aeroplane, EASA AD 2006-
0090 [which corresponds to FAA AD 2007-15-08] was issued * * *.
    Since the original Issue of the SB, three revisions have been 
published. Revision 1 of the SB included only editorial changes. 
Revision 2 of the SB corrected the fuselage frame designations in 
Parts 50 and 50A and extended the allowable time before initial 
inspection. In addition, the repeat inspection interval in Part 43 
of the SB was reduced. In the latest Revision 3 of the SB, the grace 
period for the initial inspection in Part 50 has been clarified.
* * * * *
The unsafe condition is fatigue cracking of certain structural 
elements, which could result in reduced structural integrity of the 
airplane and consequent rapid decompression of the airplane. This AD 
requires actions that are intended to address the unsafe condition 
described in the MCAI.

DATES: This AD becomes effective March 12, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of March 12, 
2010.
    On September 21, 2006 (71 FR 52418, September 6, 2006), the 
Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD.

SUPPLEMENTARY INFORMATION:

Discussion

    On July 15, 2007, we issued AD 2007-15-08, Amendment 39-15137 (72 
FR 40230, July 24, 2007). That AD required actions intended to address 
an unsafe condition on the products listed above.
    Since we issued AD 2007-15-08, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, has issued EASA Airworthiness Directive 2009-0074, 
dated March 31, 2009 (referred to after this as ``the MCAI''), to 
correct an unsafe condition for the specified products. The MCAI 
states:

    A review of the results of the final fuselage fatigue test 
identified the need for additional and revised safety-related 
fatigue- and environmental inspections for the fuselage. These 
additional tasks were introduced by Service Bulletin (SB) ATP-51-
002, which supplemented and in some cases revised those previously 
published in the Aircraft Maintenance Manual (AMM) Chapter 05-10-17 
and the Maintenance Review Board Report (MRBR).
    As it was determined that these inspections were necessary to 
maintain the structural integrity of the aeroplane, EASA AD 2006-
0090 [which corresponds to FAA AD 2007-15-08] was issued to require 
the inspections and, depending on findings, corrective actions as 
defined in BAE Systems (Operations) Limited SB ATP-51-002 (the SB) 
at original issue.
    Since the original Issue of the SB, three revisions have been 
published. Revision 1 of the SB included only editorial changes. 
Revision 2 of the SB corrected the fuselage frame designations in 
Parts 50 and 50A and extended the allowable time before initial

[[Page 8468]]

inspection. In addition, the repeat inspection interval in Part 43 
of the SB was reduced. In the latest Revision 3 of the SB, the grace 
period for the initial inspection in Part 50 has been clarified.
    Fatigue tasks in Parts 1 through 50 of the SB, i.e. those 
without an ``A'' suffix, have now been replicated in AMM Chapter 05-
10-17 and MRBR Section 6. In addition, environmental tasks, those 
identified with an ``A'' suffix, have now been replicated in MRBR 
Section 6.
    For the reasons described above, this AD retains the 
requirements of EASA AD 2006-0090, which is superseded, and requires 
the accomplishment of the inspections and, depending on findings, 
corrective actions as defined in BAE Systems (Operations) Limited SB 
ATP-51-002 at Revision 3.

The unsafe condition is fatigue cracking of certain structural 
elements, which could result in reduced structural integrity of the 
airplane and consequent rapid decompression of the airplane. The 
corrective actions include repairing cracking and corrosion, and 
depending on findings, repairing or replacing damaged components. You 
may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

    BAE SYSTEMS (Operations) Limited has issued Service Bulletin ATP-
51-002, Revision 3, dated April 3, 2008. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.

FAA's Determination and Requirements of This AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future.

Differences Between the 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 FAA policies. Any such differences are 
highlighted in a NOTE within the AD.

Change to Existing AD

    This AD retains all requirements of AD 2007-15-08. Since AD 2007-
15-08 was issued, the AD format has been revised, and certain 
paragraphs have been rearranged. As a result, the corresponding 
paragraph identifiers have changed in this AD, as listed in the 
following table:

                      Revised Paragraph Identifiers

             paragraph (k)                       paragraph (l).
------------------------------------------------------------------------

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2010-0130; Directorate 
Identifier 2009-NM-087-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about 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 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.

2010-05-05 BAE Systems (Operations) Limited: Amendment 39-16214. 
Docket No. FAA-2010-0130; Directorate Identifier 2009-NM-087-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective March 
12, 2010.

Affected ADs

    (b) This AD supersedes AD 2007-15-08, Amendment 39-15137.

Applicability

    (c) This AD applies to all BAE Systems (Operations) Limited 
Model ATP airplanes, certificated in any category.

    Note 1: This AD requires revisions to certain operator 
maintenance documents to include new and revised inspections. 
Compliance with these inspections is required by 14 CFR 91.403(c). 
For airplanes that have been previously modified, altered, or 
repaired in the areas addressed by these inspections, the operator 
may not be able to accomplish the inspections described in the 
revisions. In this situation, to comply with 14 CFR 91.403(c), the 
operator must request approval for an alternative method of 
compliance according to paragraph (q) of this AD. The request should 
include a description of changes to the required inspections that 
will ensure the continued damage tolerance of the affected 
structure. The FAA has provided guidance for this determination in 
Advisory Circular (AC) 25-1529.

Subject

    (d) Air Transport Association (ATA) of America Code: 51: 
Standard Practices/Procedures.

Reason

    (e) The mandatory continued airworthiness information (MCAI) 
states:

    A review of the results of the final fuselage fatigue test 
identified the need for additional and revised safety-related 
fatigue- and environmental inspections for the fuselage. These 
additional tasks were introduced by Service Bulletin (SB) ATP-51-
002, which supplemented and in some cases revised those previously 
published in the Aircraft Maintenance Manual (AMM) Chapter 05-10-17 
and the Maintenance Review Board Report (MRBR).
    As it was determined that these inspections were necessary to 
maintain the structural integrity of the aeroplane, EASA AD 2006-
0090 [which corresponds to FAA AD 2007-15-08] was issued to require 
the inspections and, depending on findings, corrective actions as 
defined in BAE Systems (Operations) Limited SB ATP-51-002 (the SB) 
at original issue.
    Since the original Issue of the SB, three revisions have been 
published. Revision 1 of the SB included only editorial changes. 
Revision 2 of the SB corrected the fuselage frame designations in 
Parts 50 and 50A and extended the allowable time before initial 
inspection. In addition, the repeat inspection interval in Part 43 
of the SB was reduced. In the latest Revision 3 of the SB, the grace 
period for the initial inspection in Part 50 has been clarified.
    Fatigue tasks in Parts 1 through 50 of the SB, i.e. those 
without an ``A'' suffix, have now been replicated in AMM Chapter 05-
10-17 and MRBR Section 6. In addition, environmental tasks, those 
identified with an ``A'' suffix, have now been replicated in MRBR 
Section 6.
    For the reasons described above, this AD retains the 
requirements of EASA AD 2006-0090, which is superseded, and requires 
the accomplishment of the inspections and, depending on findings, 
corrective actions as defined in BAE Systems (Operations) Limited SB 
ATP-51-002 at Revision 3.

The unsafe condition is fatigue cracking of certain structural 
elements, which could result in reduced structural integrity of the 
airplane and consequent rapid decompression of the airplane. The 
corrective actions include repairing cracking and corrosion, and 
depending on findings, repairing or replacing damaged components.

Compliance

    (f) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Restatement of Requirements of AD 2006-18-09, With Revised Compliance 
Method

Airworthiness Limitations Revision Specified in AD 2000-26-10

FAA AD Differences

    Note 5: This AD differs from the MCAI and/or service information 
as follows: No differences.

Other FAA AD Provisions

    (q) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, 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, International Branch, ANM-
