[FR Doc. 2013–15949 Filed 7–2–13; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2013–0539; Directorate Identifier 2012–NM–145–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of Proposed Rulemaking (NPRM). AGENCY: We propose to supersede airworthiness directive (AD) 2000–12– 11, that applies to certain Model A300 B4–600 and Model A300 B4–600R series airplanes. That AD currently requires repetitive inspections to detect cracks in the bolt holes inboard and outboard of rib 9 on the bottom booms of the front and rear wing spars, and repair if necessary. Since we issued that AD, we have determined through a fleet survey SUMMARY: PO 00000 Frm 00025 Fmt 4702 Sfmt 4702 40069 and an updated fatigue and damage tolerance analysis that the risk for fatigue cracking on the front and rear spar bottom booms is higher than was initially determined. This proposed AD would reduce the initial inspection compliance time and repetitive inspection interval. We are proposing this AD to detect and correct fatigue cracks in the bolt holes of the wing spars, which could result in reduced structural integrity of a wing spar. DATES: We must receive comments on this proposed AD by August 19, 2013.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. tkelley on DSK3SPTVN1PROD with PROPOSALS Discussion On June 9, 2000, we issued AD 2000– 12–11, Amendment 39–11789 (65 FR 37853, June 19, 2000). That AD requires actions intended to address an unsafe condition on the products listed above. Since we issued AD 2000–12–11, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0138, dated July 26, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Full fatigue tests carried out by the manufacturer revealed crack initiation from the bolts holes at inboard and outboard of rib 9, on the front and rear spar bottom booms. Similar cracks at the same area were reported by A300–600 aeroplane operators. This condition, if not detected and corrected, could affect the structural integrity of the aeroplane. To address this unsafe condition, ´ ´ [Direction Generale de l’Aviation Civile] DGAC France issued AD 94–208–169(B)R2 [which corresponds to FAA AD 95–07–05 Amendment 39–9187 (60 FR 17990, April 10, 1995)] to require an ultrasonic inspection of holes inboard and outboard of rib 9 on the front and rear spar bottom booms on Left Hand and Right Hand wings. Since that [DGAC] AD was issued, a fleet survey and updated Fatigue and Damage Tolerance analysis have been performed in order to substantiate the second A300–600 Extended Service Goal (ESG2) exercise. The results of these analyses have shown that the risk for these aeroplanes is higher than initially determined and that, consequently, the inspection threshold and interval must be reduced to allow timely detection of cracks VerDate Mar<15>2010 16:18 Jul 02, 2013 Jkt 229001 and the accomplishment of an applicable corrective action [and related investigative action]. For the reasons explained above, this new [EASA] AD retains the requirements of DGAC France AD 94–208–169(B)R2, which is superseded, and requires the accomplishment instructions within the new thresholds and intervals specified in Revision 04 of Airbus Mandatory Service Bulletin (SB) A300–57–6037 [dated February 24, 2011]. The related investigative action includes doing inspections for cracking. The corrective actions include oversizing holes and installing new fasteners, and for certain conditions, contacting the FAA or EASA (or its delegated agent) for instructions. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Mandatory Service Bulletin A300–57–6037, Revision 04, dated February 24, 2011. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 29 products of U.S. registry. We estimate that it would take about 18 work-hours per product to comply with the new basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $2,874 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $127,716, or $4,404 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. Differences Between This AD and the MCAI or Service Information 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. Airbus Mandatory Service Bulletin A300–57–6037, Revision 04, dated February 24, 2011, specifies to contact the manufacturer for instructions on how to repair certain conditions, but this proposed AD would require repairing those conditions using a method approved by the FAA or the EASA (or its delegated agent). In light of the type of repair that would be required to address the unsafe condition, and consistent with existing bilateral airworthiness agreements, we have determined that, for this proposed AD, a repair approved by the FAA or the EASA (or its delegated agent) would be acceptable for compliance with this proposed AD. 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); 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.

Will not affect intrastate aviation in Alaska; and 4. 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.

SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Emergency AD No.: 2012–0046–E, dated March 21, 2012 (EAD 2012–0046–E), to correct an unsafe condition for Eurocopter Model AS332 C1 and AS332 L1 helicopters. EASA advises that an AS332 helicopter was found on the production line with non-conforming rivets installed on the RH and LH longitudinal beams Y350 of the bottom structure of the fuselage, between sections X4780 and X5295. According to EASA, the investigation revealed that a limited number of helicopters were documented as receiving a production modification requiring the replacement of certain 3.2 mm rivets with 4.8 mm rivets, but the actual replacement of the rivets had not been performed. EASA states that this condition leads to significant reduction in the safety margins during sling operations and may cause failure of the web/flange assembly connections of the longitudinal beams Y350, possibly resulting in loss of control of the helicopter. For these reasons, EASA issued EAD 2012–0046–E, which, pending inspection of the helicopter beams Y350 and replacement of the affected rivets, prohibits sling operations or limits the 3-ton sling to external loads of 2.28 tons or less.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of Proposed Rulemaking (NPRM).

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

SUMMARY: We propose to supersede airworthiness directive (AD) 2000-12-
11, that applies to certain Model A300 B4-600 and Model A300 B4-600R 
series airplanes. That AD currently requires repetitive inspections to 
detect cracks in the bolt holes inboard and outboard of rib 9 on the 
bottom booms of the front and rear wing spars, and repair if necessary. 
Since we issued that AD, we have determined through a fleet survey and 
an updated fatigue and damage tolerance analysis that the risk for 
fatigue cracking on the front and rear spar bottom booms is higher than 
was initially determined. This proposed AD would reduce the initial 
inspection compliance time and repetitive inspection interval. We are 
proposing this AD to detect and correct fatigue cracks in the bolt 
holes of the wing spars, which could result in reduced structural 
integrity of a wing spar.

DATES: We must receive comments on this proposed AD by August 19, 2013.

Discussion

    On June 9, 2000, we issued AD 2000-12-11, Amendment 39-11789 (65 FR 
37853, June 19, 2000). That AD requires actions intended to address an 
unsafe condition on the products listed above.
    Since we issued AD 2000-12-11, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, has issued EASA Airworthiness Directive 2012-0138, 
dated July 26, 2012 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    Full fatigue tests carried out by the manufacturer revealed 
crack initiation from the bolts holes at inboard and outboard of rib 
9, on the front and rear spar bottom booms. Similar cracks at the 
same area were reported by A300-600 aeroplane operators.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aeroplane.
    To address this unsafe condition, [Direction 
G[eacute]n[eacute]rale de l'Aviation Civile] DGAC France issued AD 
94-208-169(B)R2 [which corresponds to FAA AD 95-07-05 Amendment 39-
9187 (60 FR 17990, April 10, 1995)] to require an ultrasonic 
inspection of holes inboard and outboard of rib 9 on the front and 
rear spar bottom booms on Left Hand and Right Hand wings.
    Since that [DGAC] AD was issued, a fleet survey and updated 
Fatigue and Damage Tolerance analysis have been performed in order 
to substantiate the second A300-600 Extended Service Goal (ESG2) 
exercise. The results of these analyses have shown that the risk for 
these aeroplanes is higher than initially determined and that, 
consequently, the inspection threshold and interval must be reduced 
to allow timely detection of cracks and the accomplishment of an 
applicable corrective action [and related investigative action].
    For the reasons explained above, this new [EASA] AD retains the 
requirements of DGAC France AD 94-208-169(B)R2, which is superseded, 
and requires the accomplishment instructions within the new 
thresholds and intervals specified in Revision 04 of Airbus 
Mandatory Service Bulletin (SB) A300-57-6037 [dated February 24, 
2011].

    The related investigative action includes doing inspections for 
cracking. The corrective actions include oversizing holes and 
installing new fasteners, and for certain conditions, contacting the 
FAA or EASA (or its delegated agent) for instructions. You may obtain 
further information by examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A300-57-6037, Revision 
04, dated February 24, 2011. 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

    Airbus Mandatory Service Bulletin A300-57-6037, Revision 04, dated 
February 24, 2011, specifies to contact the manufacturer for 
instructions on how to repair certain conditions, but this proposed AD 
would require repairing those conditions using a method approved by the 
FAA or the EASA (or its delegated agent). In light of the type of 
repair that would be required to address the unsafe condition, and 
consistent with existing bilateral airworthiness agreements, we have 
determined that, for this proposed AD, a repair approved by the FAA or 
the EASA (or its delegated agent) would be acceptable for compliance 
with this proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 29 products of U.S. registry.
    We estimate that it would take about 18 work-hours per product to 
comply with the new basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $2,874 
per product. Where the service information lists required parts costs 
that are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of the proposed AD 
on U.S. operators to be $127,716, or $4,404 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.

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);

[[Page 40071]]

    3. Will not affect intrastate aviation in Alaska; and
    4. 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.
