AGENCY:
SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD results
from mandatory continuing
airworthiness information (MCAI)
issued by an airworthiness authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as fatigue damage with a
crack propagation through the fastener
line of the wing shroud box bottom
panel, resulting in panel detachment
and potential injuries to persons on the
ground. We are issuing this AD to
require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective May
18, 2007.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of May 18, 2007.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA is implementing a new
process for streamlining the issuance of
ADs related to MCAI. This streamlined
process will allow us to adopt MCAI
safety requirements in a more efficient
manner and will reduce safety risks to
the public. This process continues to
allow all FAA AD issuance processes to
meet legal, economic, Administrative
Procedure Act, and Federal Register
requirements. We also continue to meet
our technical decision-making
responsibilities to identify and correct
unsafe conditions on U.S.-certificated
products.
This AD references the MCAI and
related service information that we
considered in forming the engineering
basis to correct the unsafe condition.
The AD contains text copied from the
MCAI and for this reason might not
follow our plain language principles.
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 January 26, 2007 (72 FR
3771). That NPRM proposed to require
performing a one-time detailed
inspection of the shroud box bottom
panel for cracks, fasteners missing or
loose, damage, and marks; and applying
all applicable corrective actions. The
MCAI states that an A330 operator has
reported a shroud box bottom panel
missing during routine inspection. The
same panel detached from an A330
aircraft during take-off, causing damages
to the surrounding structure and to the
Trimmable Horizontal Stabilizer (THS)
tip fairing. Preliminary inspection has
shown that the blind rivets used to
attach the panel worked loose causing
the panel to suffer fatigue damage with
a crack propagation through the fastener
line resulting in panel detachment. To
avoid potential injuries to persons on
ground, the MCAI mandates a one time
detailed visual inspection of the shroud
box bottom panel for cracks in the panel

and for missing and loose fasteners, and
repair if necessary.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Clarification of Service Bulletin
Reference
The ‘‘Relevant Service Information’’
section of the NPRM, and paragraph (g)
of the NPRM refer to Airbus Service
Bulletin A330–57A3092, February 3,
2006, as one of the appropriate sources
of service information to do the actions
in the NPRM. However, in paragraph (e)
of the NPRM, we inadvertently referred
to Airbus Service Bulletin A330–
57A3792, dated February 3, 2006. We
have revised paragraph (e) of this AD
accordingly.
Conclusion
We reviewed the available data, and
determined that air safety and the
public interest require adopting the AD
with the change described previously.
We determined that this change will not
increase the economic burden on any
operator or increase the scope of the AD.
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 a U.S.
court of law. 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
described in a separate paragraph of the
AD. These requirements, if any, take
precedence over the actions copied from
the MCAI.
Costs of Compliance
We estimate that this AD will affect
27 products of U.S. registry. We also
estimate that it will take about 2 workhours per product to comply with this
AD. The average labor rate is $80 per
work-hour. Based on these figures, we
E:\FR\FM\13APR1.SGM
13APR1
18564
Federal Register / Vol. 72, No. 71 / Friday, April 13, 2007 / Rules and Regulations
estimate the cost of this AD to the U.S.
operators to be $4,320, or $160 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.
cprice-sewell on PRODPC61 with RULES
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 that this AD:
(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.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://dms.dot.gov; or in
person at the Docket Management
Facility 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 Office (telephone (800) 647–

Comments will be available in the AD
docket shortly after receipt.

PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
I
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:
I
2007–08–05 Airbus: Amendment 39–15022.
Docket No. FAA–2007–27013;
Directorate Identifier 2006–NM–236–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective May 18, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus Model A330–
200, A330–300, A340–200, and A340–300
series airplanes, all certified models, all
serial numbers, certificated in any category,
on which Airbus Modification 42061 or
46077 or 53604 has been embodied in

Reason
(d) The mandatory continuing
airworthiness information (MCAI) states that
an A330 operator has reported a shroud box
bottom panel missing during routine
inspection. The same panel detached from an
A330 aircraft during take-off, causing
damages to the surrounding structure and to
the Trimmable Horizontal Stabilizer (THS)
tip fairing. Preliminary inspection has shown
that the blind rivets used to attach the panel
worked loose causing the panel to suffer
fatigue damage with a crack propagation
through the fastener line resulting in panel
detachment. To avoid potential injuries to
persons on ground, the MCAI requires a one
time detailed visual inspection of the shroud
box bottom panel for cracks in the panel and
for missing and loose fasteners, and
applicable repairs.
Actions and Compliance
(e) Unless already done, do the following
actions. Within the threshold specified in
paragraphs (e)(1) and (e)(2) of this AD and in

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 that this AD:
(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.
Examining the AD Docket
You may examine the AD docket on the Internet at https://
dms.dot.gov; or in person at the Docket Management Facility 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
Office (telephone (800) 647-5227) is in the ADDRESSES section. Comments
will be available in the AD docket shortly after receipt.

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:
2007-08-05 Airbus: Amendment 39-15022. Docket No. FAA-2007-27013;
Directorate Identifier 2006-NM-236-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective May 18,
2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus Model A330-200, A330-300, A340-
200, and A340-300 series airplanes, all certified models, all serial
numbers, certificated in any category, on which Airbus Modification
42061 or 46077 or 53604 has been embodied in production and
delivered before December 31, 2005.
Reason
(d) The mandatory continuing airworthiness information (MCAI)
states that an A330 operator has reported a shroud box bottom panel
missing during routine inspection. The same panel detached from an
A330 aircraft during take-off, causing damages to the surrounding
structure and to the Trimmable Horizontal Stabilizer (THS) tip
fairing. Preliminary inspection has shown that the blind rivets used
to attach the panel worked loose causing the panel to suffer fatigue
damage with a crack propagation through the fastener line resulting
in panel detachment. To avoid potential injuries to persons on
ground, the MCAI requires a one time detailed visual inspection of
the shroud box bottom panel for cracks in the panel and for missing
and loose fasteners, and applicable repairs.
Actions and Compliance
(e) Unless already done, do the following actions. Within the
threshold specified in paragraphs (e)(1) and (e)(2) of this AD and
in accordance with the instructions of Airbus Service Bulletin A330-
57A3092, dated February 3, 2006; or Airbus Service Bulletin A340-
57A4101, dated February 3, 2006; as applicable: Perform a one-time
detailed inspection of the shroud box bottom panel for cracks,
fasteners missing or loose, damage, and marks; and apply all
applicable corrective actions. Do applicable corrective actions
before further flight. The inspections results, whatever they are,
must be reported to Airbus.
(1) For Model A330 airplanes: Whichever occurs later between
paragraphs (e)(1)(i) and (e)(1)(ii) of this AD.
(i) Prior to the accumulation of 1,200 flight cycles or 2,400
flight hours from the first flight of the aircraft, whichever occurs
first.
(ii) Within 6 months or 1,200 flight hours, whichever occurs
first, following the effective date of this AD.
(2) For Model A340-200 and A340-300 series airplanes: Whichever
occurs later between paragraphs (e)(2)(i) and (e)(2)(ii) of this AD.
(i) Prior to the accumulation of 1,200 flight cycles or 4,800
flight hours from the first flight of the aircraft, whichever occurs
first.
(ii) Within 6 months or 2,400 flight hours, whichever occurs
first, following the effective date of this AD.
Other FAA AD Provisions
(f) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, ANM-116, Transport Airplane Directorate, FAA,
Attn: Tim Backman, Aerospace Engineer, 1601 Lind Avenue, SW.,
Renton, Washington 98057-3356, has the authority to approve AMOCs
for this AD, if requested using the procedures found in 14 CFR
39.19. Before using any AMOC approved in accordance with Sec. 39.19
on any airplane to which the AMOC applies, notify the appropriate
principal inspector in the FAA Flight Standards Certificate Holding
District Office.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in
this AD, under the provisions of the Paperwork Reduction Act, the
Office of Management and Budget (OMB) has approved the information
collection requirements and has assigned OMB Control Number 2120-
