E7–10670 Filed 6–4–07; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2007–26856; Directorate Identifier 2006–NM–125–AD; Amendment 39–15082; AD 2007–12–04] RIN 2120–AA64 Airworthiness Directives; Airbus Model A300 B4–600, B4–600R, and F4–600R Series Airplanes, and Model C4–605R Variant F Airplanes (Collectively Called A300–600 Series Airplanes) Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. cprice-sewell on PROD1PC71 with RULES AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD) that applies to all Airbus Model A300– 600 series airplanes. That AD currently requires inspections of the lower door surrounding structure to detect cracks and corrosion; inspections to detect cracking of the holes of the corner VerDate Aug<31>2005 15:27 Jun 04, 2007 Jkt 211001 doublers, the fail-safe ring, and the door frames of the door structures; and repair if necessary. That AD also provides for optional terminating action for certain inspections. This new AD retains all requirements of the existing AD, mandates the previously optional terminating action, reduces the applicability of the existing AD, and adds repetitive inspections behind scuff plates for certain affected airplanes. This AD results from a determination that further rulemaking is necessary to improve the fatigue behavior of the cabin door surroundings. We are issuing this AD to prevent corrosion between the scuff plates at exit and cargo doors and fatigue cracks originating from certain fastener holes located in adjacent structure, which could result in reduced structural integrity of the door surroundings. DATES: This AD becomes effective July 10, 2007. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of July 10, 2007. On September 4, 1998 (63 FR 40812, July 31, 1998), the Director of the Federal Register approved the incorporation by reference of certain other publications listed in the AD.

SUPPLEMENTARY INFORMATION: Examining the Docket You may examine the airworthiness directive (AD) docket on the Internet at https://dms.dot.gov or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. 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 supersedes AD 98–16–05, amendment 39–10680 (63 FR 40812, July 31, 1998). The existing AD applies to all Airbus Model A300–600 series airplanes. That E:\FR\FM\05JNR1.SGM 05JNR1 30962 Federal Register / Vol. 72, No. 107 / Tuesday, June 5, 2007 / Rules and Regulations NPRM was published in the Federal Register on January 19, 2007 (72 FR 2469). That NPRM proposed to continue the requirements of AD 98–16–05. These requirements are inspections of the lower door surrounding structure to detect cracks and corrosion; inspections to detect cracking of the holes of the corner doublers, the fail-safe ring, and the door frames of the door structures; and repair if necessary. That NPRM also proposed to mandate the previously optional terminating action, reduce the applicability of the existing AD, and add repetitive inspections behind scuff plates for certain affected airplanes. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments that have been received on the NPRM. Request To Give Credit for Previous Inspections FedEx concurs with the NPRM, but requests that we give credit for previous inspections accomplished in accordance with AD 98–16–05. FedEx points out that this credit should be given for actions in paragraphs (f), (g), (j), (k), (n), and (r) of the NPRM. We partially agree with the request. We agree that it is necessary for the AD to give credit for inspections accomplished previously in accordance with AD 98–16–05. We disagree that it is necessary to change the AD in this regard. Paragraph (e) of the AD states ‘‘You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.’’ Therefore, the AD already gives credit for required actions that were accomplished according to AD 98–16– 05. Request To Allow Previously Granted Alternate Methods of Compliance (AMOCs) FedEx also suggests that AMOCs issued per AD 98–16–05 be granted as applicable to the NPRM. We agree that we should approve AMOCs for this AD that were approved previously in accordance with AD 98– 16–05. We disagree with changing the AD in this regard. Paragraph (t)(2) of both the NPRM and the AD already approves previous AMOCs. Request To Address Repairs Outside Limits FedEx requests that we add wording to paragraphs (l)(2) and (t) of the NPRM to address repairs outside the applicable service bulletins or that exceed the service bulletin limits. (Airbus Service Bulletin A300–53–6018, Revision 1, dated April 29, 1992; or Revision 02, dated November 27, 2000; are the applicable service bulletins for paragraph (l)(2); and paragraph (t) is the AMOC paragraph.) FedEx suggests the following wording: ‘‘If any crack or corrosion is detected during any inspection required by this AD and the applicable service bulletin specifies to contact the manufacturer for disposition of corrective actions: Prior to further flight, repair in accordance with a method approved by either the Manager, International Branch, ANM–116, or DGAC/EASA, or its delegated agent.’’ We disagree with the request to add the suggested words. There are no limits specified in the service bulletins. We cannot approve repairs that exceed the limits of the service bulletin unless the excess limits are defined. However, affected operators may request approval of AMOCs, under the provisions of paragraph (t) of the AD. Conclusion We have carefully reviewed the available data, including the comments that have been submitted, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this AD. The average labor rate per work hour is $80. ESTIMATED COSTS Number of U.S.-registered airplanes Action Work hours Parts Cost per airplane Repetitive inspections behind scuff plates.

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 VerDate Aug<31>2005 15:27 Jun 04, 2007 Jkt 211001 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. PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 Fleet cost 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: E:\FR\FM\05JNR1.SGM 05JNR1 Federal Register / Vol. 72, No. 107 / Tuesday, June 5, 2007 / Rules and Regulations (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.

Amendment 39-15082; AD 2007-12-04]
RIN 2120-AA64

Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and
F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes
(Collectively Called A300-600 Series Airplanes)

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) that applies to all Airbus Model A300-600 series airplanes. That
AD currently requires inspections of the lower door surrounding
structure to detect cracks and corrosion; inspections to detect
cracking of the holes of the corner doublers, the fail-safe ring, and
the door frames of the door structures; and repair if necessary. That
AD also provides for optional terminating action for certain
inspections. This new AD retains all requirements of the existing AD,
mandates the previously optional terminating action, reduces the
applicability of the existing AD, and adds repetitive inspections
behind scuff plates for certain affected airplanes. This AD results
from a determination that further rulemaking is necessary to improve
the fatigue behavior of the cabin door surroundings. We are issuing
this AD to prevent corrosion between the scuff plates at exit and cargo
doors and fatigue cracks originating from certain fastener holes
located in adjacent structure, which could result in reduced structural
integrity of the door surroundings.

DATES: This AD becomes effective July 10, 2007.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of July 10, 2007.
On September 4, 1998 (63 FR 40812, July 31, 1998), the Director of
the Federal Register approved the incorporation by reference of certain
other publications listed in the AD.

ADDRESSES: You may examine the AD docket on the Internet at https://
dms.dot.gov or in person at the Docket Management Facility, U.S.
Department of Transportation, 400 Seventh Street, SW., Nassif Building,
Room PL-401, Washington, DC.

SUPPLEMENTARY INFORMATION:

Examining the Docket

You may examine the airworthiness directive (AD) docket on the
Internet at https://dms.dot.gov or in person at the Docket Management
Facility office between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. 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 supersedes AD 98-16-05, amendment 39-
10680 (63 FR 40812, July 31, 1998). The existing AD applies to all
Airbus Model A300-600 series airplanes. That

[[Page 30962]]

NPRM was published in the Federal Register on January 19, 2007 (72 FR
2469). That NPRM proposed to continue the requirements of AD 98-16-05.
These requirements are inspections of the lower door surrounding
structure to detect cracks and corrosion; inspections to detect
cracking of the holes of the corner doublers, the fail-safe ring, and
the door frames of the door structures; and repair if necessary. That
NPRM also proposed to mandate the previously optional terminating
action, reduce the applicability of the existing AD, and add repetitive
inspections behind scuff plates for certain affected airplanes.

Comments

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

Request To Give Credit for Previous Inspections

FedEx concurs with the NPRM, but requests that we give credit for
previous inspections accomplished in accordance with AD 98-16-05. FedEx
points out that this credit should be given for actions in paragraphs
(f), (g), (j), (k), (n), and (r) of the NPRM.
We partially agree with the request. We agree that it is necessary
for the AD to give credit for inspections accomplished previously in
accordance with AD 98-16-05. We disagree that it is necessary to change
the AD in this regard. Paragraph (e) of the AD states ``You are
responsible for having the actions required by this AD performed within
the compliance times specified, unless the actions have already been
done.'' Therefore, the AD already gives credit for required actions
that were accomplished according to AD 98-16-05.

Request To Allow Previously Granted Alternate Methods of Compliance
(AMOCs)

FedEx also suggests that AMOCs issued per AD 98-16-05 be granted as
applicable to the NPRM.
We agree that we should approve AMOCs for this AD that were
approved previously in accordance with AD 98-16-05. We disagree with
changing the AD in this regard. Paragraph (t)(2) of both the NPRM and
the AD already approves previous AMOCs.

Request To Address Repairs Outside Limits

FedEx requests that we add wording to paragraphs (l)(2) and (t) of
the NPRM to address repairs outside the applicable service bulletins or
that exceed the service bulletin limits. (Airbus Service Bulletin A300-
53-6018, Revision 1, dated April 29, 1992; or Revision 02, dated
November 27, 2000; are the applicable service bulletins for paragraph
(l)(2); and paragraph (t) is the AMOC paragraph.) FedEx suggests the
following wording: ``If any crack or corrosion is detected during any
inspection required by this AD and the applicable service bulletin
specifies to contact the manufacturer for disposition of corrective
actions: Prior to further flight, repair in accordance with a method
approved by either the Manager, International Branch, ANM-116, or DGAC/
EASA, or its delegated agent.''
We disagree with the request to add the suggested words. There are
no limits specified in the service bulletins. We cannot approve repairs
that exceed the limits of the service bulletin unless the excess limits
are defined. However, affected operators may request approval of AMOCs,
under the provisions of paragraph (t) of the AD.

Conclusion

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

Costs of Compliance

The following table provides the estimated costs for U.S. operators
to comply with this AD. The average labor rate per work hour is $80.

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 30963]]

(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.
