Airworthiness Directives; BAE SYSTEMS (Operations) Limited Model ATP Airplanes
AGENCY:
Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION:
Final rule; request for comments.
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.
We must receive comments on this AD by April 12, 2010.

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 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:
| Requirement in AD 2007-15-08 | Corresponding requirement in this AD |
|---|---|
| paragraph (f) | paragraph (g). |
| paragraph (g) | paragraph (h). |
| paragraph (h) | paragraph (i). |
| paragraph (i) | paragraph (j). |
| paragraph (j) | paragraph (k). |
| 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.
List of Subjects in 14 CFR Part 39

Adoption of the Amendment
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.
§ 39.13 [Amended]
2. The FAA amends § 39.13 by removing Amendment 39-15137 (72 FR 40230, July 24, 2007) and adding the following new AD:
2010-05-05BAE 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.
