The MCAI states: Prompted by cracks found on the Frame (FR) 47 angle fitting, Airbus issued SB VerDate Sep<11>2014 16:57 Jun 01, 2018 Jkt 244001 [Service Bulletin] A300–57–6049, SB A300– 57–6050, and SB A300–57–6086. These cracks, if not detected and corrected, could affect the structural integrity of the centre wing box (CWB) of the aeroplane. ´ ´ Consequently, DGAC [Direction Generale de l’Aviation Civile] France published AD 94–241–170, AD 1999–147–279, AD 2000– 533–328 and AD F–2004–159 (EASA approval 2004–9779), each AD superseding the previous one, to require repetitive high frequency eddy current (HFEC) rotating probe inspections of the FR47 internal lower angle fitting. After DGAC France AD F–2004–159 was issued, cracks were reportedly found on the horizontal flange of FR47 internal corner angle fitting during accomplishment of routine maintenance structural inspection and modification in accordance with the instructions of Airbus SB A300–57–6050. Prompted by these findings, Airbus reviewed and amended the inspection programme for the internal lower angle fitting flange (horizontal face). Consequently, EASA issued AD 2012–0092 [which corresponds to FAA AD 2014–20–18, Amendment 39–17991 (79 FR 65879, November 6, 2014) (‘‘AD 2014–20–18’’)], retaining the requirements of DGAC France AD F–2004–159, which was superseded, and requiring additional repetitive inspections of the CWB lower panel through the ultrasonic method and, depending on findings, reinstallation of removed fasteners in transition fit instead of interface. In addition, DGAC France had previously issued AD F–2005–124 (EASA approval 2005–6071) to require the same inspections for A300 F4–608ST aeroplanes, in accordance with Airbus SB A300–57–9001 and SB A300–57–9002. Following the discovery of numerous cracks during the accomplishment of SB A300–57–6049 and SB A300–57–6089 inspections, Airbus developed in a first step a new (recommended) modification (Airbus SB A300–57–6113) and defined, for post-mod aeroplanes, new inspections, and published SB A300–57–6119, which included new inspection methods (ultrasonic/radiographic) with new inspection thresholds and intervals. Consequently, EASA issued AD 2016– 0198, retaining the requirements of EASA AD 2012–0092, which was superseded, to require repetitive inspections for post-SB A300–57– 6113 aeroplanes. Since EASA AD 2016–0198 was issued, Airbus revised in a second step the inspection programme for A300–600 pre-SB 57–6113 and A300–600ST aeroplanes, reducing inspection thresholds and intervals. At this opportunity, the existing ultrasonic inspection for A300–600 aeroplanes has been added for A300–600ST aeroplanes. For the reasons described above, this new [EASA] AD retains the requirements of EASA AD 2016–0198 for A300–600 aeroplanes and of DGAC France AD F–2005–124 for A300– 600ST aeroplanes, which are both superseded, and requires [modification through cold expansion of certain angle fitting attachment holes and] repetitive inspections [for cracking of certain holes of the internal lower angle fitting web, certain PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 25591 holes of the internal lower angle fitting horizontal splicing, the aft bottom panel, and the FR47/Rib 1 junction area, and applicable related investigative and corrective actions] with new compliance times and intervals. This [EASA] AD is applicable to both A300– 600 and A300–600ST aeroplanes * * *. Related investigative actions include a rotating probe inspection for cracking. Corrective actions include replacing damaged fasteners, reaming and drilling holes, installing the next nominal fastener for oversized bore holes, and repairing cracks. You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2018–0497. Relationship Between Proposed AD and AD 2014–20–18 This NPRM would not supersede AD 2014–20–18. Rather, we have determined that a stand-alone AD would be more appropriate to address the changes in the MCAI. This NPRM would require depending on airplane configuration, a modification of certain angle fitting attachment holes, inspections for cracking of certain holes of the internal lower angle fitting web, certain holes of the internal lower angle fitting horizontal splicing, the aft bottom panel, and the FR47/Rib 1 junction area. Accomplishment of the proposed modification and initial inspections would then terminate all of the requirements of AD 2014–20–18. Related Service Information Under 1 CFR Part 51 Airbus has issued the following service information. • Service Bulletin A300–57–6049, Revision 8, dated July 4, 2017. This service information describes procedures for HFEC rotating probe inspections for cracking of certain holes of the internal lower angle fitting web. • Service Bulletin A300–57–6086, Revision 6, dated July 4, 2017. This service information describes procedures for HFEC rotating probe inspections for cracking of certain holes in the internal lower angle fitting horizontal splicing (left-hand and righthand sides) and for ultrasonic inspections for cracking of the aft bottom panel. • Service Bulletin A300–57–6119, Revision 00, dated April 25, 2016. This service information describes procedures for ultrasonic and radiographic inspections for cracking of the FR47/Rib 1 junction area. This service information is reasonably available because the interested parties have access to it through their normal E:\FR\FM\04JNP1.SGM 04JNP1 25592 Federal Register / Vol. 83, No. 107 / Monday, June 4, 2018 / Proposed Rules course of business or by the means identified in the ADDRESSES section. 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. Costs of Compliance We estimate that this proposed AD affects 65 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators Up to 727 work-hours × $85 per hour = Up to $61,795 ....... Up to $3,370 ......... Up to $65,165 ....... Up to $4,235,725 per inspection cycle. We estimate that it would take about 1 work-hour per product to comply with the proposed reporting requirement in this proposed AD. The average labor rate is $85 per hour. Based on these figures, we estimate the cost of reporting the inspection results on U.S. operators to be $5,525, or $85 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD. Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this NPRM is 2120–0056. The paperwork cost associated with this NPRM has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this NPRM is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES–200. sradovich on DSK3GMQ082PROD with PROPOSALS 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: VerDate Sep<11>2014 16:57 Jun 01, 2018 Jkt 244001 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. 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); 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.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Model A300 B4-603, B4-620, and B4-622 airplanes; Model 
A300 F4-605R airplanes; Model A300 C4-605R Variant F airplanes; and 
Model A300 B4-600R series airplanes. This proposed AD was prompted by 
reports of cracking on the frame (FR) 47 angle fitting. This proposed 
AD would require, depending on airplane configuration, a modification 
of certain angle fitting attachment holes, repetitive inspections for 
cracking of certain holes of the internal lower angle fitting web, 
certain holes of the internal lower angle fitting horizontal splicing, 
the aft bottom panel, and the FR47/Rib 1 junction area, and related 
investigative and corrective actions if necessary. We are proposing 
this AD to address the unsafe condition on these products.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0210, dated October 24, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Airbus Model A300 B4-603, B4-
620, and B4-622 airplanes; Model A300 F4-605R airplanes; Model A300 C4-
605R Variant F airplanes; and Model A300 B4-600R series airplanes. The 
MCAI states:

    Prompted by cracks found on the Frame (FR) 47 angle fitting, 
Airbus issued SB [Service Bulletin] A300-57-6049, SB A300-57-6050, 
and SB A300-57-6086.
    These cracks, if not detected and corrected, could affect the 
structural integrity of the centre wing box (CWB) of the aeroplane.
    Consequently, DGAC [Direction G[eacute]n[eacute]rale de 
l'Aviation Civile] France published AD 94-241-170, AD 1999-147-279, 
AD 2000-533-328 and AD F-2004-159 (EASA approval 2004-9779), each AD 
superseding the previous one, to require repetitive high frequency 
eddy current (HFEC) rotating probe inspections of the FR47 internal 
lower angle fitting.
    After DGAC France AD F-2004-159 was issued, cracks were 
reportedly found on the horizontal flange of FR47 internal corner 
angle fitting during accomplishment of routine maintenance 
structural inspection and modification in accordance with the 
instructions of Airbus SB A300-57-6050. Prompted by these findings, 
Airbus reviewed and amended the inspection programme for the 
internal lower angle fitting flange (horizontal face).
    Consequently, EASA issued AD 2012-0092 [which corresponds to FAA 
AD 2014-20-18, Amendment 39-17991 (79 FR 65879, November 6, 2014) 
(``AD 2014-20-18'')], retaining the requirements of DGAC France AD 
F-2004-159, which was superseded, and requiring additional 
repetitive inspections of the CWB lower panel through the ultrasonic 
method and, depending on findings, re-installation of removed 
fasteners in transition fit instead of interface.
    In addition, DGAC France had previously issued AD F-2005-124 
(EASA approval 2005-6071) to require the same inspections for A300 
F4-608ST aeroplanes, in accordance with Airbus SB A300-57-9001 and 
SB A300-57-9002.
    Following the discovery of numerous cracks during the 
accomplishment of SB A300-57-6049 and SB A300-57-6089 inspections, 
Airbus developed in a first step a new (recommended) modification 
(Airbus SB A300-57-6113) and defined, for post-mod aeroplanes, new 
inspections, and published SB A300-57-6119, which included new 
inspection methods (ultrasonic/radiographic) with new inspection 
thresholds and intervals.
    Consequently, EASA issued AD 2016-0198, retaining the 
requirements of EASA AD 2012-0092, which was superseded, to require 
repetitive inspections for post-SB A300-57-6113 aeroplanes.
    Since EASA AD 2016-0198 was issued, Airbus revised in a second 
step the inspection programme for A300-600 pre-SB 57-6113 and A300-
600ST aeroplanes, reducing inspection thresholds and intervals. At 
this opportunity, the existing ultrasonic inspection for A300-600 
aeroplanes has been added for A300-600ST aeroplanes.
    For the reasons described above, this new [EASA] AD retains the 
requirements of EASA AD 2016-0198 for A300-600 aeroplanes and of 
DGAC France AD F-2005-124 for A300-600ST aeroplanes, which are both 
superseded, and requires [modification through cold expansion of 
certain angle fitting attachment holes and] repetitive inspections 
[for cracking of certain holes of the internal lower angle fitting 
web, certain holes of the internal lower angle fitting horizontal 
splicing, the aft bottom panel, and the FR47/Rib 1 junction area, 
and applicable related investigative and corrective actions] with 
new compliance times and intervals. This [EASA] AD is applicable to 
both A300-600 and A300-600ST aeroplanes * * *.

    Related investigative actions include a rotating probe inspection 
for cracking. Corrective actions include replacing damaged fasteners, 
reaming and drilling holes, installing the next nominal fastener for 
oversized bore holes, and repairing cracks. You may examine the MCAI in 
the AD docket on the internet at http://www.regulations.gov by 
searching for and locating Docket No. FAA-2018-0497.

Relationship Between Proposed AD and AD 2014-20-18

    This NPRM would not supersede AD 2014-20-18. Rather, we have 
determined that a stand-alone AD would be more appropriate to address 
the changes in the MCAI. This NPRM would require depending on airplane 
configuration, a modification of certain angle fitting attachment 
holes, inspections for cracking of certain holes of the internal lower 
angle fitting web, certain holes of the internal lower angle fitting 
horizontal splicing, the aft bottom panel, and the FR47/Rib 1 junction 
area. Accomplishment of the proposed modification and initial 
inspections would then terminate all of the requirements of AD 2014-20-
18.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information.
     Service Bulletin A300-57-6049, Revision 8, dated July 4, 
2017. This service information describes procedures for HFEC rotating

[[Page 25592]]

course of business or by the means identified in the ADDRESSES section.

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.

Costs of Compliance

    We estimate that this proposed AD affects 65 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.
            Labor cost                      Parts cost                Cost per product            operators
----------------------------------------------------------------------------------------------------------------
Up to 727 work-hours x $85 per     Up to $3,370...............  Up to $65,165..............  Up to $4,235,725
 hour = Up to $61,795.                                                                        per inspection
                                                                                              cycle.
----------------------------------------------------------------------------------------------------------------

    We estimate that it would take about 1 work-hour per product to 
comply with the proposed reporting requirement in this proposed AD. The 
average labor rate is $85 per hour. Based on these figures, we estimate 
the cost of reporting the inspection results on U.S. operators to be 
$5,525, or $85 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this AD.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this NPRM is 2120-
0056. The paperwork cost associated with this NPRM has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this NPRM is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes to the Director of the System Oversight 
Division.

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);
    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.
