ACTION: Final rule. AGENCY: 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: rwilkins on PROD1PC63 with RULES During fatigue tests (EF3) on the A340–600, multiple damage were found in the upper side shell structure at skin and frame (FR) 84 & 85 interface, from stringer 6 to 15 LH/RH. This damage occurred between 58,341 and 72,891 simulated Flight Cycles (FC). Due to the higher Design Service Goal and different design (e.g. skin thickness) for A330–200 and A340–300 aircraft series, the damage assessment concluded on [a] potential impact on these aircraft series. * * * * * The unsafe condition is loss of integrity of the upper shell structure of the fuselage. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective August 21, 2008.

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 March 3, 2008 (73 FR 11364). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: During fatigue tests (EF3) on the A340–600, multiple damage were found in the upper side shell structure at skin and frame (FR) 84 & 85 interface, from stringer 6 to 15 LH/RH. This damage occurred between 58,341 and 72,891 simulated Flight Cycles (FC). Due to the higher Design Service Goal and different design (e.g. skin thickness) for A330–200 and A340–300 aircraft series, the damage assessment concluded on [a] potential impact on these aircraft series. In order to allow early detection of cracks which could avoid possible crack propagation and consequently to maintain the structural integrity of the upper side shell structure between FR84 and FR87, this Airworthiness Directive (AD) mandates an inspection program of this area [for cracking] using a high frequency eddy current (HFEC) method and a modification to improve the upper shell structure. This Revision 1 is issued to clarify that this AD is not applicable to aircraft A340–300 series on which both AIRBUS modifications 44205 and 45012 have been embodied in production. The unsafe condition is loss of integrity of the upper shell structure of the fuselage between FR84 and FR87. Corrective actions include contacting Airbus and repairing any crack. 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 considered the comments received. Request To Remove Reference to Modification Air Transport Association (ATA) on behalf of its member Northwest Airlines (NWA), requests that we remove the reference to Airbus Modification (Mod.) 44205 from paragraph (c), ‘‘Applicability,’’ of the NPRM. The commenters explain that Mod. 44205 defines common structure for Section 19. Mod. 45012, which is in paragraph (f)(1) of the NPRM, modifies the Section PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 19 upper side shell on A330–200 series airplanes. We disagree. Cracks can develop on this area of Section 19 that affect basic airplanes fitted with the same features (i.e., post-Mod. 44205). For Model A340–300 series airplanes, Mod. 45012 addresses the unsafe condition. Therefore, only Model A340–300 series airplanes on which both Mod. 44205 and 45012 have been done in production are exempt. Analysis further to these findings established that cracking would also affect airplanes post-Mod. 45012 on Model A330–200 series airplanes. The mandated action separates pre- or post-Mod. 45012, as specified in paragraphs (f)(1) and (f)(2) of this AD. We have made no change to the AD in this regard. Request To Exclude Certain Airplanes The same commenters request that we exclude from paragraph (f)(1) and Table 1 of the NPRM airplanes that have Mod. 52974 or 53223 embodied. The commenters explain that paragraph (c) excludes these airplanes, but paragraph (f)(1) and Table 1 do not exclude them. Without the exclusion, four more NWA airplanes are affected by the AD. We disagree. Paragraph (f)(1), which includes Table 1, refers to paragraph (c) where the two modifications are listed as exclusions. There is no need to exclude the airplanes again in paragraph (f)(1) or Table 1 of the AD. We have made no change to the AD in this regard. Request To Move ‘‘Before Further Flight’’ Requirement The same commenters request that we move the requirement to ‘‘Do all applicable corrective actions before further flight’’ from paragraph (f)(1) of the NPRM to the ‘‘Threshold’’ column of Table 1 of the NPRM. The commenters explain that moving this statement would make it clear that corrective action is required at the time of the mandated inspection thresholds and not before. We disagree. Paragraph (f)(1)(i) of this AD, which includes Table 1, gives thresholds for doing the HFEC inspection. Paragraph (f)(1)(ii) of this AD also gives a possible threshold for the HFEC inspection. The requirement is to do the applicable corrective actions before further flight. We have made no change to the AD in this regard. Conclusion We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD as proposed. E:\FR\FM\17JYR1.SGM 17JYR1 Federal Register / Vol. 73, No. 138 / Thursday, July 17, 2008 / Rules and Regulations 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 will affect about 7 products of U.S. registry. We also estimate that it will take about 601 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $52,160 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD on the U.S. operators to be $701,680, or $100,240 per product. rwilkins on PROD1PC63 with RULES 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 VerDate Aug<31>2005 18:28 Jul 16, 2008 Jkt 214001 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. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: I 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. [Amended] 2. The FAA amends § 39.13 by adding the following new AD: I 2008–14–17 Airbus: Amendment 39–15612. Docket No. FAA–2008–0232; Directorate Identifier 2007–NM–309–AD. Effective Date (a) This airworthiness directive (AD) becomes effective August 21, 2008. Affected ADs (b) None. PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 Applicability (c) This AD applies to Airbus Model A330– 200 and A340–300 series airplanes, certificated in any category, all certified models; all serial numbers on which Airbus Modification 44205 has been embodied in production, except those on which Airbus Modification 52974 or 53223 has been embodied in production. This AD is not applicable to Model A340–300 series airplanes on which both Modifications 44205 and 45012 have been embodied in production. Subject (d) Air Transport Association (ATA) of America Code 53: Fuselage. Reason (e) The mandatory continuing airworthiness information (MCAI) states: During fatigue tests (EF3) on the A340–600, multiple damage were found in the upper side shell structure at skin and frame (FR) 84 & 85 interface, from stringer 6 to 15 LH/RH. This damage occurred between 58,341 and 72,891 simulated Flight Cycles (FC). Due to the higher Design Service Goal and different design (e.g. skin thickness) for A330–200 and A340–300 aircraft series, the damage assessment concluded on [a] potential impact on these aircraft series. In order to allow early detection of cracks which could avoid possible crack propagation and consequently to maintain the structural integrity of the upper side shell structure between FR84 and FR87, this Airworthiness Directive (AD) mandates an inspection program of this area [for cracking] using a high frequency eddy current (HFEC) method and a modification to improve the upper shell structure. This Revision 1 is issued to clarify that this AD is not applicable to aircraft A340–300 series on which both AIRBUS modifications 44205 and 45012 have been embodied in production. The unsafe condition is loss of integrity of the upper shell structure of the fuselage between FR84 and FR87. Corrective actions include contacting Airbus and repairing any crack.

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:

    During fatigue tests (EF3) on the A340-600, multiple damage were 
found in the upper side shell structure at skin and frame (FR) 84 & 
85 interface, from stringer 6 to 15 LH/RH. This damage occurred 
between 58,341 and 72,891 simulated Flight Cycles (FC).
    Due to the higher Design Service Goal and different design (e.g. 
skin thickness) for A330-200 and A340-300 aircraft series, the 
damage assessment concluded on [a] potential impact on these 
aircraft series.
* * * * *
The unsafe condition is loss of integrity of the upper shell structure 
of the fuselage. We are issuing this AD to require actions to correct 
the unsafe condition on these products.

DATES: This AD becomes effective August 21, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 21, 
2008.

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 March 3, 2008 (73 FR 
11364). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    During fatigue tests (EF3) on the A340-600, multiple damage were 
found in the upper side shell structure at skin and frame (FR) 84 & 
85 interface, from stringer 6 to 15 LH/RH. This damage occurred 
between 58,341 and 72,891 simulated Flight Cycles (FC).
    Due to the higher Design Service Goal and different design (e.g. 
skin thickness) for A330-200 and A340-300 aircraft series, the 
damage assessment concluded on [a] potential impact on these 
aircraft series.
    In order to allow early detection of cracks which could avoid 
possible crack propagation and consequently to maintain the 
structural integrity of the upper side shell structure between FR84 
and FR87, this Airworthiness Directive (AD) mandates an inspection 
program of this area [for cracking] using a high frequency eddy 
current (HFEC) method and a modification to improve the upper shell 
structure.
    This Revision 1 is issued to clarify that this AD is not 
applicable to aircraft A340-300 series on which both AIRBUS 
modifications 44205 and 45012 have been embodied in production.

The unsafe condition is loss of integrity of the upper shell structure 
of the fuselage between FR84 and FR87. Corrective actions include 
contacting Airbus and repairing any crack. 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 considered the comments received.

Request To Remove Reference to Modification

    Air Transport Association (ATA) on behalf of its member Northwest 
Airlines (NWA), requests that we remove the reference to Airbus 
Modification (Mod.) 44205 from paragraph (c), ``Applicability,'' of the 
NPRM. The commenters explain that Mod. 44205 defines common structure 
for Section 19. Mod. 45012, which is in paragraph (f)(1) of the NPRM, 
modifies the Section 19 upper side shell on A330-200 series airplanes.
    We disagree. Cracks can develop on this area of Section 19 that 
affect basic airplanes fitted with the same features (i.e., post-Mod. 
44205). For Model A340-300 series airplanes, Mod. 45012 addresses the 
unsafe condition. Therefore, only Model A340-300 series airplanes on 
which both Mod. 44205 and 45012 have been done in production are 
exempt. Analysis further to these findings established that cracking 
would also affect airplanes post-Mod. 45012 on Model A330-200 series 
airplanes. The mandated action separates pre- or post-Mod. 45012, as 
specified in paragraphs (f)(1) and (f)(2) of this AD. We have made no 
change to the AD in this regard.

Request To Exclude Certain Airplanes

    The same commenters request that we exclude from paragraph (f)(1) 
and Table 1 of the NPRM airplanes that have Mod. 52974 or 53223 
embodied. The commenters explain that paragraph (c) excludes these 
airplanes, but paragraph (f)(1) and Table 1 do not exclude them. 
Without the exclusion, four more NWA airplanes are affected by the AD.
    We disagree. Paragraph (f)(1), which includes Table 1, refers to 
paragraph (c) where the two modifications are listed as exclusions. 
There is no need to exclude the airplanes again in paragraph (f)(1) or 
Table 1 of the AD. We have made no change to the AD in this regard.

Request To Move ``Before Further Flight'' Requirement

    The same commenters request that we move the requirement to ``Do 
all applicable corrective actions before further flight'' from 
paragraph (f)(1) of the NPRM to the ``Threshold'' column of Table 1 of 
the NPRM. The commenters explain that moving this statement would make 
it clear that corrective action is required at the time of the mandated 
inspection thresholds and not before.
    We disagree. Paragraph (f)(1)(i) of this AD, which includes Table 
1, gives thresholds for doing the HFEC inspection. Paragraph (f)(1)(ii) 
of this AD also gives a possible threshold for the HFEC inspection. The 
requirement is to do the applicable corrective actions before further 
flight. We have made no change to the AD in this regard.

Conclusion

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

[[Page 40959]]

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 will affect about 7 products of U.S. 
registry. We also estimate that it will take about 601 work-hours per 
product to comply with the basic requirements of this AD. The average 
labor rate is $80 per work-hour. Required parts will cost about $52,160 
per product. Where the service information lists required parts costs 
that are covered under warranty, we have assumed that there will be no 
charge for these costs. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of this AD on the 
U.S. operators to be $701,680, or $100,240 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 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.

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 adding the following new AD:

2008-14-17 Airbus: Amendment 39-15612. Docket No. FAA-2008-0232; 
Directorate Identifier 2007-NM-309-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective August 
21, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A330-200 and A340-300 series 
airplanes, certificated in any category, all certified models; all 
serial numbers on which Airbus Modification 44205 has been embodied 
in production, except those on which Airbus Modification 52974 or 
53223 has been embodied in production. This AD is not applicable to 
Model A340-300 series airplanes on which both Modifications 44205 
and 45012 have been embodied in production.

Subject

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

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    During fatigue tests (EF3) on the A340-600, multiple damage were 
found in the upper side shell structure at skin and frame (FR) 84 & 
85 interface, from stringer 6 to 15 LH/RH. This damage occurred 
between 58,341 and 72,891 simulated Flight Cycles (FC).
    Due to the higher Design Service Goal and different design (e.g. 
skin thickness) for A330-200 and A340-300 aircraft series, the 
damage assessment concluded on [a] potential impact on these 
aircraft series.
    In order to allow early detection of cracks which could avoid 
possible crack propagation and consequently to maintain the 
structural integrity of the upper side shell structure between FR84 
and FR87, this Airworthiness Directive (AD) mandates an inspection 
program of this area [for cracking] using a high frequency eddy 
current (HFEC) method and a modification to improve the upper shell 
structure.
    This Revision 1 is issued to clarify that this AD is not 
applicable to aircraft A340-300 series on which both AIRBUS 
modifications 44205 and 45012 have been embodied in production.

The unsafe condition is loss of integrity of the upper shell 
structure of the fuselage between FR84 and FR87. Corrective actions 
include contacting Airbus and repairing any crack.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) For Airbus Model A330-200 series airplanes, as identified in 
paragraph (c) of this AD, on which Modification 45012 has been 
embodied in production: At the later of the compliance times 
specified in paragraphs (f)(1)(i) and (f)(1)(ii) of this AD, do the 
HFEC inspection for cracking, and corrective actions as applicable; 
and modify the upper shell structure of the fuselage; in accordance 
with the Accomplishment Instructions of Airbus Service Bulletin 
A330-53-3152, dated April 10, 2007. Do all applicable corrective 
actions before further flight.
    (i) Prior to the compliance time shown in Table 1 of this AD 
after the first flight of the airplane, depending on airplane 
configuration.
