ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for the products listed above that would supersede two existing ADs. 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: SUMMARY: ´ ´ DGAC [Direction Generale de l’Aviation Civile] France AD 1992–106–132(B) * * * PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 01 02 02 Date May 22, 2007.

We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective June 15, 2011. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of June 15, 2011. The Director of the Federal Register approved the incorporation by reference of certain other publications listed in this AD as of January 20, 1999 (63 FR 69179, December 16, 1998).

SUPPLEMENTARY INFORMATION: Discussion srobinson on DSKHWCL6B1PROD with RULES 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 3, 2011 (76 FR 42), and proposed to supersede AD 98–26– 01, Amendment 39–10942 (63 FR 69179, December 16, 1998), and AD 91– 13–01, Amendment 39–7032 (56 FR 26602, June 10, 1991). The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: ´ ´ DGAC [Direction Generale de l’Aviation Civile] France AD 1992–106–132(B) original issue up to revision 7 has been issued in order to mandate a set of inspections/ modifications which address JAR/FAR [Joint Aviation Regulation/Federal Aviation Regulation] 25–571 requirements related to damage-tolerance and fatigue evaluation of structure [FAA AD 98–26–01 corresponds to DGAC AD 1992–106–132(B)R4, dated June 5, 1996]. Following the Extended Design Service Goal activities part of the Structure Task Group for the A310 program, EASA AD 2007–0053 superseded DGAC France AD F–1992–106–132R7 in order to take into account the publication of Airbus Service Bulletins (SB) A310–55–2004 at Revision 5 and Airbus SB A310–53–2074 at Revision 3, whose inspection thresholds and/or intervals had been reduced. Revision 1 of this AD was issued to remove the mandatory requirements related to the wings (i.e. § 1.8, 1.9, 1.10, 1.13, and 1.18) from the Compliance section, which have been transferred to EASA AD 2007–0242. Revision 2 of this AD has been issued to remove the mandatory requirements of paragraph 1.15, 1.16 and 1.17 which have now been transferred to EASA AD 2009–0057 (§ 1.15 and 1.17) and 2009–0058 (§ 1.16) respectively. Revision 3 of this AD is issued to add a Note to the Applicability and amend the Required Action(s) and Compliance Time(s) section of this AD to clarify the allowed use of the referenced SBs by operators. In addition, a note has been added to paragraph 1.7 and the notes associated to paragraphs 1.1, 1.2, 1.3, 1.4, 1.5 and 1.12 have been clarified. The unsafe condition is reduced structural integrity of the wings, fuselage, and stabilizers. This NPRM proposed to continue to require certain actions specified in AD 98–26–01. VerDate Mar<15>2010 16:21 May 10, 2011 Jkt 223001 The NPRM also proposed to expand the inspection area of the high frequency eddy current rototest inspection required by paragraph (g) of AD 98–26–01. The required actions are as follows, depending on airplane configuration: • A defectoscope or rototest inspection to detect cracks in the area of frame 47 and frame 54, install new doublers, and repair if necessary. • Repetitive visual inspections to detect cracks on frame 46 between the left- and right-hand sides of stringers 21 and 22 on the forward and aft faces, and repair if necessary. • Repetitive visual inspections to detect cracks at the T-section connecting frame 50A to the beam between the leftand right-hand sides of frames 50 and 51, and modification if necessary. • Repetitive visual inspections to detect cracks in the lower milled side panel at the lap joint with the upper side panel at frame 47 and stringer 22, left- and right-hand sides, and repair if necessary. • An eddy current inspection to detect cracks on the upper integral part adjacent to the rear attach fittings on the horizontal stabilizer, modification of the horizontal stabilizer, and repair if necessary. • Repetitive high frequency eddy current rototest inspections for cracking of the doubler plate edge, rear spar area, and at specified fastener holes in the top skin chordwise splice along the contour of the steel doubler between ribs 3 and 4 on the left- and right-hand center and side boxes on the horizontal stabilizer, installing new fasteners if no cracking is found, and repair if necessary. • Repetitive inspections, either an eddy current or visual inspection, to detect cracks on the left and right vertical posts, numbers 1 through 5 inclusive, in the wing center box at frame 40/41, and modification if necessary. 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 received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 27233 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 44 products of U.S. registry. The actions that are required by AD 98–26–01 and are retained in this AD take about 1,087 work-hours per product, at an average labor rate of $85 per work hour. Required parts cost about $81,973 per product. Based on these figures, the estimated cost of the currently required actions is $174,368 per product. We also estimate that it will take about 3 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $11,220, or $255 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 E:\FR\FM\11MYR1.SGM 11MYR1 27234 Federal Register / Vol. 76, No. 91 / Wednesday, May 11, 2011 / Rules and Regulations 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 https:// 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.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above that would supersede two existing ADs. 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:

DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile]
France AD 1992-106-132(B) * * * has been issued in order to mandate
a set of inspections/modifications which address JAR/FAR [Joint
Aviation Regulation/Federal Aviation Regulation] 25-571 requirements
related to damage-tolerance and fatigue evaluation of structure.
* * * * *

The unsafe condition is reduced structural integrity of the wings,
fuselage, and stabilizers. We are issuing this AD to require actions to
correct the unsafe condition on these products.

DATES: This AD becomes effective June 15, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of June 15,
2011.
The Director of the Federal Register approved the incorporation by

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 January 3, 2011 (76
FR 42), and proposed to supersede AD 98-26-01, Amendment 39-10942 (63
FR 69179, December 16, 1998), and AD 91-13-01, Amendment 39-7032 (56 FR
26602, June 10, 1991).
The NPRM proposed to correct an unsafe condition for the specified
products. The MCAI states:

DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile]
France AD 1992-106-132(B) original issue up to revision 7 has been
issued in order to mandate a set of inspections/modifications which
address JAR/FAR [Joint Aviation Regulation/Federal Aviation
Regulation] 25-571 requirements related to damage-tolerance and
fatigue evaluation of structure [FAA AD 98-26-01 corresponds to DGAC
AD 1992-106-132(B)R4, dated June 5, 1996].
Following the Extended Design Service Goal activities part of
the Structure Task Group for the A310 program, EASA AD 2007-0053
superseded DGAC France AD F-1992-106-132R7 in order to take into
account the publication of Airbus Service Bulletins (SB) A310-55-
2004 at Revision 5 and Airbus SB A310-53-2074 at Revision 3, whose
inspection thresholds and/or intervals had been reduced.
Revision 1 of this AD was issued to remove the mandatory
requirements related to the wings (i.e. Sec. 1.8, 1.9, 1.10, 1.13,
and 1.18) from the Compliance section, which have been transferred
to EASA AD 2007-0242.
Revision 2 of this AD has been issued to remove the mandatory
requirements of paragraph 1.15, 1.16 and 1.17 which have now been
transferred to EASA AD 2009-0057 (Sec. 1.15 and 1.17) and 2009-0058
(Sec. 1.16) respectively.
Revision 3 of this AD is issued to add a Note to the
Applicability and amend the Required Action(s) and Compliance
Time(s) section of this AD to clarify the allowed use of the
referenced SBs by operators. In addition, a note has been added to
paragraph 1.7 and the notes associated to paragraphs 1.1, 1.2, 1.3,
1.4, 1.5 and 1.12 have been clarified.

The unsafe condition is reduced structural integrity of the wings,
fuselage, and stabilizers.
This NPRM proposed to continue to require certain actions specified
in AD 98-26-01.
The NPRM also proposed to expand the inspection area of the high
frequency eddy current rototest inspection required by paragraph (g) of
AD 98-26-01. The required actions are as follows, depending on airplane
configuration:
A defectoscope or rototest inspection to detect cracks in
the area of frame 47 and frame 54, install new doublers, and repair if
necessary.
Repetitive visual inspections to detect cracks on frame 46
between the left- and right-hand sides of stringers 21 and 22 on the
forward and aft faces, and repair if necessary.
Repetitive visual inspections to detect cracks at the T-
section connecting frame 50A to the beam between the left- and right-
hand sides of frames 50 and 51, and modification if necessary.
Repetitive visual inspections to detect cracks in the
lower milled side panel at the lap joint with the upper side panel at
frame 47 and stringer 22, left- and right-hand sides, and repair if
necessary.
An eddy current inspection to detect cracks on the upper
integral part adjacent to the rear attach fittings on the horizontal
stabilizer, modification of the horizontal stabilizer, and repair if
necessary.
Repetitive high frequency eddy current rototest
inspections for cracking of the doubler plate edge, rear spar area, and
at specified fastener holes in the top skin chordwise splice along the
contour of the steel doubler between ribs 3 and 4 on the left- and
right-hand center and side boxes on the horizontal stabilizer,
installing new fasteners if no cracking is found, and repair if
necessary.
Repetitive inspections, either an eddy current or visual
inspection, to detect cracks on the left and right vertical posts,
numbers 1 through 5 inclusive, in the wing center box at frame 40/41,
and modification if necessary. 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 received no comments on the NPRM or on the determination of
the cost to the public.

Conclusion

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

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 44 products of U.S. registry.
The actions that are required by AD 98-26-01 and are retained in this
AD take about 1,087 work-hours per product, at an average labor rate of
$85 per work hour. Required parts cost about $81,973 per product. Based
on these figures, the estimated cost of the currently required actions
is $174,368 per product.
We also estimate that it will take about 3 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Based on these figures, we estimate the cost
of this AD to the U.S. operators to be $11,220, or $255 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

[[Page 27234]]

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 https://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.
