That AD required actions intended to address an unsafe condition on the products listed above. Since we issued AD 98–26–01, we have determined that certain compliance times need to be reduced in order to adequately address the identified unsafe condition. Therefore, certain requirements of paragraphs (h), (i), (j), (m), (n), and (s) of that AD are included in this NPRM. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2007–0242, dated September 4, 2007 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: ´ ´ DGAC [Direction Generale de l’Aviation Civile] France Airworthiness Directive (AD) 1992–106–132(B) original issue up to VerDate Mar<15>2010 19:10 Dec 30, 2010 Jkt 223001 revision 7 was issued to require a set of inspection- and modification tasks which addressed 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 as part of the Structure Task Group for the Airbus A310 program, EASA issued AD 2007–0053 which replaced DGAC France AD F–1992–106–132R7. Since the issuance of that AD, the thresholds and the intervals of some Airbus Service Bulletins (SBs which address structure fatigue related areas on the wing parts), until now part of the requirements of AD 2007–0053, have been updated. For the reasons stated above, this new [EASA] AD requires the accomplishment of the structural fatigue-related corrective actions in accordance with the latest revision of these SBs which have been reviewed in the context of the A310 Extended Service Goal activities. Consequently, this new AD supersedes the requirements of paragraphs 1.8, 1.9, 1.10, 1.13, 1.18 of EASA AD 2007– 0053, which has been revised accordingly. The unsafe condition is reduced structural integrity of the wings. The required actions are as follows, depending on airplane configuration: • For certain Model A310–203 and A310–222 airplanes: Repetitive detailed inspections for cracking of the leading edge access panels around the bolt holes, and repair if necessary. • For certain Model A310–203, A310–204, A310–222, A310–304, A310– 322, A310–324, and A310–325 airplanes: Repetitive eddy current inspections to detect cracks in the holes around the overwing refueling aperture at ribs 13–14, and repair if necessary. • For certain Model A310–203, A310–204, A310–222, A310–304, A310– 322, A310–324, and A310–325 airplanes: Repetitive external detailed inspections for cracking of the top skin at ribs 13–14, repetitive internal detailed inspections for cracking of stringer 7 and stringer 8 of the overwing refuel aperture, and repair if necessary. • For certain Model A310–203 and A310–222 airplanes: Repetitive detailed inspections for cracking around the bolts in the wing top skin upper surface of the front spar between rib 7 and rib 28, and repair if necessary. • For certain Model A310–203 and A310–222 airplanes: Repetitive high frequency eddy current (HFEC) or X-ray inspections to detect cracking of the stringer runouts inboard and outboard of rib 14 at stringers 6, 7, 8, and 9, and repair if necessary. PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 35 • For certain Model A310–203, A310–204, A310–222, A310–304, A310A–322, and A310–324 airplanes: Repetitive ultrasonic inspections for cracking in certain bolt holes where the main landing gear forward pick-up fitting is attached to the rear spar, and repair if necessary. You may obtain further information by examining the MCAI in the AD docket. Other Relevant Rulemaking On September 5, 1990, we issued AD 90–19–07, Amendment 39–6731 (55 FR 37455), for certain Airbus Model A310– 200 series airplanes, to require repetitive X-ray inspections of stringers 6, 7, 8, and 9 run-outs inboard and outboard of rib 14, and repair if necessary. Accomplishing an inspection in accordance with paragraph (l) of this AD would terminate the requirements of paragraph (a) of AD 90–19–07. On March 6, 1991, we issued AD 91– 06–18, amendment 39–6940 (56 FR 10796), for all Airbus Model A310–200 series airplanes, to require repetitive high frequency eddy current (HFEC) rototest inspections to detect cracks in the wing rear spar at certain bolt holes where the main landing gear (MLG) forward pick-up fittings are attached to the rear spar, and repair, if necessary. Accomplishing an inspection in accordance with paragraph (q) of this AD would terminate the requirements of AD 91–06–18, amendment 39–6940. We are also considering issuing three other NPRMs related to this NPRM: • Directorate Identifier 2010–NM– 092–AD. That NPRM proposes to supersede AD 98–26–01, amendment 39–10942 (63 FR 69179, December 16, 1998), to continue to require certain actions specified in that AD. However, that NPRM does not restate paragraphs (h), (i), (j), (m), (n), and (s) of AD 98– 26–01. Instead, certain requirements of paragraphs (h), (i), (j), (m), (n), and (s) of that AD are included in this NPRM, Directorate Identifier 2010–NM–091– AD. • Directorate Identifiers 2010–NM– 089–AD and 2010–NM–090–AD. Both of these NPRMs include the requirements of certain other paragraphs of AD 98– 26–01. Relevant Service Information Airbus has issued the service bulletins listed in the table below.

FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. 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 proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 44 products of U.S. registry. We also estimate that it would take about 97 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $362,780, or $8,245 per product. 03 04 04 04 08 the FAA proposes to amend 14 CFR part 39 as follows: (b) This AD affects AD 90–19–07, Amendment 39–6731; and AD 91–06–18, Amendment 39–6940. We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation: 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 proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Title 49 of the United States Code specifies the FAA’s authority to issue 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. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: Airbus: Docket No. FAA–2010–1275; Directorate Identifier 2010–NM–091–AD. Comments Due Date (a) We must receive comments by February 17, 2011. Affected ADs Applicability (c) This AD applies to Airbus Model A310– 203, –204, –221, –222, –304, –322, –324, and –325 airplanes, certificated in any category, all certified models, all serial numbers. Subject (d) Air Transport Association (ATA) of America Code 57: Wings. Reason (e) The mandatory continuing airworthiness information (MCAI) states: ´ ´ DGAC [Direction Generale de l’Aviation Civile] France Airworthiness Directive (AD) 1992–106–132(B) * * * was issued to require a set of inspection- and modification tasks which addressed JAR/FAR [Joint Aviation Regulation/Federal Aviation Regulation] 25–571 requirements related to damage-tolerance and fatigue evaluation of structure. * * *. * * * Jkt 223001 PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 * * The unsafe condition is reduced structural integrity of the wings. Compliance (f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Accordingly, under the authority delegated to me by the Administrator, 19:10 Dec 30, 2010 November 28, 2006. May 21, 2007. December 1, 2006. October 19, 2006. December 1, 2006. 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. Authority for This Rulemaking VerDate Mar<15>2010 Date Regulatory Findings The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. srobinson on DSKHWCL6B1PROD with PROPOSALS Revision E:\FR\FM\03JAP1.SGM 03JAP1 Federal Register / Vol. 76, No. 1 / Monday, January 3, 2011 / Proposed Rules srobinson on DSKHWCL6B1PROD with PROPOSALS Restatement of Certain Requirements of AD 98–26–01, Amendment 39–10942, With Reduced Compliance Times Leading Edge Access Panels Landing—Lower Skin—Inspection for Cracks at Bolt Holes (g) For Model A310–203 and A310–222 airplanes listed in Airbus Service Bulletin A310–57–2002, Revision 2, dated January 4, 1996, except airplanes on which Airbus modification No. 05101 has been embodied in production, or on which Airbus Service Bulletin A310–57–2003 has been embodied in service before the accumulation of 9,400 total flight cycles and 18,800 total flight hours: At the times specified in paragraph (h) of this AD, perform a detailed visual inspection to detect cracks in the external surface of the wing lower skin around the landing access panel holes of the leading edge, in accordance with the Airbus Service Bulletin A310–57–2002, Revision 1, dated July 2, 1992; Airbus Service Bulletin A310– 57–2002, Revision 2, dated January 4, 1996; or Airbus Mandatory Service Bulletin A310– 57–2002, Revision 03, dated November 28, 2006.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office. The AMOC approval letter must specifically reference this AD. AMOCs approved previously in accordance with AD 98–26–01, amendment 39–10942, are approved as AMOCs for the corresponding provisions of this AD. (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.

PO 00000 Frm 00015 Fmt 4702 Sfmt 4702 Discussion On December 8, 1998, we issued AD 98–26–01, Amendment 39–10942 (63 FR 69179, December 16, 1998); and on May 30, 1991, we issued AD 91–13–01, Amendment 39–7032 (56 FR 26602, June 10, 1991). Those ADs required actions intended to address an unsafe condition on the products listed above. Since we issued ADs 98–26–01 and 91–13–01, we have determined that certain compliance times need to be reduced in order to adequately address the identified unsafe condition. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2007–0053R3, dated December 17, 2009 (referred to after this as ‘‘the MCAI’’), 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 proposes to continue to require certain actions specified in AD 98–26–01.

Discussion

On December 8, 1998, we issued AD 98-26-01, Amendment 39-10942 (63
FR 69179, December 16, 1998). That AD required actions intended to
address an unsafe condition on the products listed above.
Since we issued AD 98-26-01, we have determined that certain
compliance times need to be reduced in order to adequately address the
identified unsafe condition. Therefore, certain requirements of
paragraphs (h), (i), (j), (m), (n), and (s) of that AD are included in
this NPRM. The European Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Community, has
issued EASA Airworthiness Directive 2007-0242, dated September 4, 2007
(referred to after this as ``the MCAI''), to correct an unsafe
condition for the specified products. The MCAI states:

DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile]
France Airworthiness Directive (AD) 1992-106-132(B) original issue
up to revision 7 was issued to require a set of inspection- and
modification tasks which addressed 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 as part of
the Structure Task Group for the Airbus A310 program, EASA issued AD
2007-0053 which replaced DGAC France AD F-1992-106-132R7. Since the
issuance of that AD, the thresholds and the intervals of some Airbus
Service Bulletins (SBs which address structure fatigue related areas
on the wing parts), until now part of the requirements of AD 2007-
0053, have been updated.
For the reasons stated above, this new [EASA] AD requires the
accomplishment of the structural fatigue-related corrective actions
in accordance with the latest revision of these SBs which have been
reviewed in the context of the A310 Extended Service Goal
activities. Consequently, this new AD supersedes the requirements of
paragraphs 1.8, 1.9, 1.10, 1.13, 1.18 of EASA AD 2007-0053, which
has been revised accordingly.

The unsafe condition is reduced structural integrity of the wings. The
required actions are as follows, depending on airplane configuration:
For certain Model A310-203 and A310-222 airplanes:
Repetitive detailed inspections for cracking of the leading edge access
panels around the bolt holes, and repair if necessary.
For certain Model A310-203, A310-204, A310-222, A310-304,
A310-322, A310-324, and A310-325 airplanes: Repetitive eddy current
inspections to detect cracks in the holes around the overwing refueling
aperture at ribs 13-14, and repair if necessary.
For certain Model A310-203, A310-204, A310-222, A310-304,
A310-322, A310-324, and A310-325 airplanes: Repetitive external
detailed inspections for cracking of the top skin at ribs 13-14,
repetitive internal detailed inspections for cracking of stringer 7 and
stringer 8 of the overwing refuel aperture, and repair if necessary.
For certain Model A310-203 and A310-222 airplanes:
Repetitive detailed inspections for cracking around the bolts in the
wing top skin upper surface of the front spar between rib 7 and rib 28,
and repair if necessary.
For certain Model A310-203 and A310-222 airplanes:
Repetitive high frequency eddy current (HFEC) or X-ray inspections to
detect cracking of the stringer runouts inboard and outboard of rib 14
at stringers 6, 7, 8, and 9, and repair if necessary.
For certain Model A310-203, A310-204, A310-222, A310-304,
A310A-322, and A310-324 airplanes: Repetitive ultrasonic inspections
for cracking in certain bolt holes where the main landing gear forward
pick-up fitting is attached to the rear spar, and repair if necessary.
You may obtain further information by examining the MCAI in the AD
docket.

Other Relevant Rulemaking

On September 5, 1990, we issued AD 90-19-07, Amendment 39-6731 (55
FR 37455), for certain Airbus Model A310-200 series airplanes, to
require repetitive X-ray inspections of stringers 6, 7, 8, and 9 run-
outs inboard and outboard of rib 14, and repair if necessary.
Accomplishing an inspection in accordance with paragraph (l) of this AD
would terminate the requirements of paragraph (a) of AD 90-19-07.
On March 6, 1991, we issued AD 91-06-18, amendment 39-6940 (56 FR
10796), for all Airbus Model A310-200 series airplanes, to require
repetitive high frequency eddy current (HFEC) rototest inspections to
detect cracks in the wing rear spar at certain bolt holes where the
main landing gear (MLG) forward pick-up fittings are attached to the
rear spar, and repair, if necessary. Accomplishing an inspection in
accordance with paragraph (q) of this AD would terminate the
requirements of AD 91-06-18, amendment 39-6940.
We are also considering issuing three other NPRMs related to this
NPRM:
Directorate Identifier 2010-NM-092-AD. That NPRM proposes
to supersede AD 98-26-01, amendment 39-10942 (63 FR 69179, December 16,
1998), to continue to require certain actions specified in that AD.
However, that NPRM does not restate paragraphs (h), (i), (j), (m), (n),
and (s) of AD 98-26-01. Instead, certain requirements of paragraphs
(h), (i), (j), (m), (n), and (s) of that AD are included in this NPRM,
Directorate Identifier 2010-NM-091-AD.
Directorate Identifiers 2010-NM-089-AD and 2010-NM-090-AD.
Both of these NPRMs include the requirements of certain other
paragraphs of AD 98-26-01.

The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.

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 proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.

Costs of Compliance

Based on the service information, we estimate that this proposed AD
would affect about 44 products of U.S. registry. We also estimate that
it would take about 97 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $362,780, or $8,245 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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
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 proposed AD and placed it in the AD docket.

FAA AD Differences

paragraph (j) of this AD requires that you repair the crack(s)
before further flight.

Other FAA AD Provisions

(v) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, ANM-116, Transport Airplane Directorate, FAA,
has the authority to approve AMOCs for this AD, if requested using
the procedures found in 14 CFR 39.19. Send information to ATTN: Dan
Rodina, Aerospace Engineer, International Branch, ANM-116, Transport
Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington
98057-3356; telephone (425) 227-2125; fax (425) 227-1149. Before
using any approved AMOC on any airplane to which the AMOC applies,
notify your principal maintenance inspector (PMI) or principal
avionics inspector (PAI), as appropriate, or lacking a principal
inspector, your local Flight Standards District Office. The AMOC
approval letter must specifically reference this AD. AMOCs approved
previously in accordance with AD 98-26-01, amendment 39-10942, are
approved as AMOCs for the corresponding provisions of this AD.
(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 (44
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has
approved the information collection requirements and has assigned
OMB Control Number 2120-0056.
