The Docket Management Facility office (telephone (800) 647–5227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section. Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain Airbus Model A330, A340–200, and A340–300 airplanes. That NPRM was published in the Federal Register on May 18, 2006 (71 FR 28819). That NPRM proposed to require replacing the attachment landing assemblies of certain blowdown panels of the wing leading edges with new, improved landing assemblies. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. 3063, or A340–57–4092 and A340–57– 4071 (these service bulletins introduced the replacements that were subsequently cited in the primary service bulletins—Airbus Service Bulletins A330–57–3091 and A340–57– 4100, both dated October 25, 2005—and mandated by EASA airworthiness directive 2006–0048). Airbus therefore requests that we revise the NPRM to agree with the EASA airworthiness directive and exclude airplanes modified in service as described in the secondary service bulletins. We partially agree. We acknowledge that airplanes which have been modified as described in the secondary service bulletins require no further work in accordance with this AD. However, we have not revised the applicability of the AD; rather, we have included a new paragraph (g) in the AD to state that replacements done in accordance with the secondary service bulletins are considered to be acceptable for compliance with the requirements of paragraph (f) of this AD. We have reidentified subsequent paragraphs of the AD accordingly. Request To Revise Applicability To Reflect Primary Service Bulletins Request To Revise Applicability To Reflect Secondary Service Bulletins Airbus states that the European Aviation Safety Agency (EASA) airworthiness directive 2006–0048, dated February 16, 2006, is written to exclude airplanes modified in service in accordance with Airbus Service Bulletins A330–57–3084 and A330–57– Airbus further requests that we revise the applicability of the NPRM to exclude certain other airplanes. Airbus states that EASA airworthiness directive 2006–0048 excludes airplanes modified in service as described in Airbus Service Bulletin A330–57–3091 or A340–57– 4100, both dated October 25, 2005, which are cited as the primary sources of service information for accomplishing the requirements of this AD. Airbus asserts that the AD should agree with the EASA airworthiness directive and exclude airplanes which have been modified in service as described in Airbus Service Bulletin A330–57–3091 or A340–57–4100. We disagree. We have not excluded those airplanes in the applicability of this AD; rather, this AD includes a requirement to accomplish the actions specified in the primary service bulletins. This requirement will ensure that the actions described in the service bulletins and required by this AD are accomplished on all affected airplanes. Operators must continue to operate the airplanes in the configuration required by this AD unless an alternative method of compliance is approved in accordance with the procedures specified in paragraph (h) of this AD. We have not revised the AD in this regard. Conclusion We have carefully reviewed the available data, including the comments received, 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 of Model A330 airplanes to comply with the modifications required by this AD. The estimated labor rate is $80 per work hour.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain Airbus Model 
A330, A340-200, and A340-300 airplanes. That NPRM was published in the 
Federal Register on May 18, 2006 (71 FR 28819). That NPRM proposed to 
require replacing the attachment landing assemblies of certain blow-
down panels of the wing leading edges with new, improved landing 
assemblies.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received.

Request To Revise Applicability To Reflect Secondary Service Bulletins

    Airbus states that the European Aviation Safety Agency (EASA) 
airworthiness directive 2006-0048, dated February 16, 2006, is written 
to exclude airplanes modified in service in accordance with Airbus 
Service Bulletins A330-57-3084 and A330-57-3063, or A340-57-4092 and 
A340-57-4071 (these service bulletins introduced the replacements that 
were subsequently cited in the primary service bulletins--Airbus 
Service Bulletins A330-57-3091 and A340-57-4100, both dated October 25, 
2005--and mandated by EASA airworthiness directive 2006-0048). Airbus 
therefore requests that we revise the NPRM to agree with the EASA 
airworthiness directive and exclude airplanes modified in service as 
described in the secondary service bulletins.
    We partially agree. We acknowledge that airplanes which have been 
modified as described in the secondary service bulletins require no 
further work in accordance with this AD. However, we have not revised 
the applicability of the AD; rather, we have included a new paragraph 
(g) in the AD to state that replacements done in accordance with the 
secondary service bulletins are considered to be acceptable for 
compliance with the requirements of paragraph (f) of this AD. We have 
re-identified subsequent paragraphs of the AD accordingly.

Request To Revise Applicability To Reflect Primary Service Bulletins

    Airbus further requests that we revise the applicability of the 
NPRM to exclude certain other airplanes. Airbus states that EASA 
airworthiness directive 2006-0048 excludes airplanes modified in 
service as described in Airbus Service Bulletin A330-57-3091 or A340-
57-4100, both dated October 25, 2005, which are cited as the primary 
sources of service information for accomplishing the requirements of 
this AD. Airbus asserts that the AD should agree with the EASA 
airworthiness directive and exclude airplanes which have been modified 
in service as described in Airbus Service Bulletin A330-57-3091 or 
A340-57-4100.
    We disagree. We have not excluded those airplanes in the 
applicability of this AD; rather, this AD includes a requirement to 
accomplish the actions specified in the primary service bulletins. This 
requirement will ensure that the actions described in the service 
bulletins and required by this AD are accomplished on all affected 
airplanes. Operators must continue to operate the airplanes in the 
configuration required by this AD unless an alternative method of 
compliance is approved in accordance with the procedures specified in 
paragraph (h) of this AD. We have not revised the AD in this regard.

Conclusion

    We have carefully reviewed the available data, including the 
comments received, 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 
of Model A330 airplanes to comply with the modifications required by 
this AD. The estimated labor rate is $80 per work hour.

----------------------------------------------------------------------------------------------------------------

    Currently, there are no Model A340-200 or A340-300 airplanes on the 
U.S. Register. However, if an affected Model A340-200 or A340-300 
airplane is imported and placed on the U.S. Register in the future, the 
estimated costs shown in the table above will apply to accomplish the 
required actions of this AD for that airplane.

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 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:

[[Page 54761]]

    (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 and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
