ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 series airplanes; and Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes). This proposed AD was prompted by reports of cracks initiating at the upper radius of frame (FR) 47 and a determination that the current inspection procedure is not reliable in detecting certain cracking of the forward fitting of FR 47. This proposed AD would require repetitive inspections to detect cracking of the upper radius of the forward fitting of FR 47, and related investigative actions and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by July 17, 2017.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016–0150, dated July 25, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition on all. The MCAI states: During scheduled maintenance inspections on the fuselage, cracks initiating at the upper radius of frame (FR) 47 have been reported on several aeroplanes. Similar damage was also discovered on the A300 fatigue test fuselage. PO 00000 Frm 00022 Fmt 4702 Sfmt 4702 24903 This condition, if not detected and corrected, could reduce the structural integrity of the fuselage. Prompted by these findings, Airbus issued Service Bulletin (SB) A300–53–0246, SB A300–53–6029 and SB A300–53–9014 to provide inspection instructions and, consequently, DGAC France issued AD F– 2006–016 to require repetitive inspections and corrective action. Since that [French] AD was issued, further investigation led to the conclusion that the current ultrasonic inspection performed in accordance with Airbus SB A300–53–0246 Revision 06, or SB A300–53–6029 Revision 08, or SB A300–53–9014 Revision 01, as applicable, was not reliable to detect deep crack going downward. Consequently, to ensure the crack depth is correctly measured whatever the crack direction, Airbus developed a new nondestructive testing method [eddy current] for this special detailed inspection (SDI) and revised the affected SBs accordingly. For the reasons described above, this [EASA] AD retains the requirements of DGAC France AD F–2006–016, which is superseded, but requires the accomplishment of repetitive SDI to replace the previously required ultrasonic inspections [and related investigative actions and corrective actions if necessary]. Related investigative actions include an ultrasonic inspection for cracking on the forward face of forward fitting and a detailed inspection for cracking of the aft fitting around the fasteners. Corrective actions include crack repairs, modification of the sealing fittings and sealing shims. This proposed AD requires reporting of the inspection results to Airbus. 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–2017–0520. Related Service Information Under 1 CFR Part 51 Airbus has issued Airbus Service Bulletin A300–53–0246, Revision 08, including Appendix 1, dated April 13, 2016 (for Model A300 series airplanes); and Airbus Service Bulletin A300–53– 6029, Revision 12, including Appendix 1, dated April 13, 2016 (for Model A300–600 series airplanes). The service information describes procedures for doing an SDI for cracking of the FR 47 forward fitting upper radius on the lefthand and right-hand sides of the fuselage, and related investigative actions and corrective actions. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. E:\FR\FM\31MYP1.SGM 31MYP1 24904 Federal Register / Vol. 82, No. 103 / Wednesday, May 31, 2017 / Proposed Rules 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 designs. This NPRM would not supersede AD 2007–26–14, Amendment 39–15316 (73 FR 2803, January 16, 2008). Rather, we have determined that a stand-alone AD would be more appropriate to address the changes in the MCAI. This NPRM would require repetitive inspections to detect cracking of the upper radius of the forward fitting of FR 47, and related investigative actions and corrective actions if necessary. Accomplishment of the proposed actions would then terminate all requirements of AD 2007– 26–14 for the inspected airplane. Differences Between This Proposed AD and the MCAI or Service Information Although the MCAI and service information allow further flight if cracks are found during accomplishment of the required action, this proposed AD requires that any cracking be repaired before further flight. Costs of Compliance We estimate that this proposed AD affects 132 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Inspection ....... Reporting ....... 19 work-hours × $85 per hour = $1,615 .... 1 work-hour × $85 per hour = $85 ............. We estimate the following costs to do any necessary related investigative and corrective actions that would be Parts cost $0 0 Cost per product Cost on U.S. operators $1,615 per inspection cycle ..... $85 per inspection cycle .......... required based on the results of the proposed inspection. We have no way of $213,180 per inspection cycle. $11,220 per inspection cycle. determining the number of airplanes that might need these repairs: ON-CONDITION COSTS Action Labor cost Related investigative and Corrective actions ............... 21 work-hours × $85 per hour = $1,785 ...................... nlaroche on DSK30NT082PROD with PROPOSALS 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 proposed AD is 2120– 0056. The paperwork cost associated with this proposed AD 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 proposed AD 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, VerDate Sep<11>2014 14:38 May 30, 2017 Jkt 241001 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. PO 00000 Frm 00023 Fmt 4702 Sfmt 4702 Parts cost Cost per product $1,835 $3,620 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

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 series airplanes; and Model A300 B4-600, B4-
600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F 
airplanes (collectively called Model A300-600 series airplanes). This 
proposed AD was prompted by reports of cracks initiating at the upper 
radius of frame (FR) 47 and a determination that the current inspection 
procedure is not reliable in detecting certain cracking of the forward 
fitting of FR 47. This proposed AD would require repetitive inspections 
to detect cracking of the upper radius of the forward fitting of FR 47, 
and related investigative actions 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 
2016-0150, dated July 25, 2016 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition on all. The MCAI states:

    During scheduled maintenance inspections on the fuselage, cracks 
initiating at the upper radius of frame (FR) 47 have been reported 
on several aeroplanes. Similar damage was also discovered on the 
A300 fatigue test fuselage.
    This condition, if not detected and corrected, could reduce the 
structural integrity of the fuselage.
    Prompted by these findings, Airbus issued Service Bulletin (SB) 
A300-53-0246, SB A300-53-6029 and SB A300-53-9014 to provide 
inspection instructions and, consequently, DGAC France issued AD F-
2006-016 to require repetitive inspections and corrective action.
    Since that [French] AD was issued, further investigation led to 
the conclusion that the current ultrasonic inspection performed in 
accordance with Airbus SB A300-53-0246 Revision 06, or SB A300-53-
6029 Revision 08, or SB A300-53-9014 Revision 01, as applicable, was 
not reliable to detect deep crack going downward.
    Consequently, to ensure the crack depth is correctly measured 
whatever the crack direction, Airbus developed a new nondestructive 
testing method [eddy current] for this special detailed inspection 
(SDI) and revised the affected SBs accordingly.
    For the reasons described above, this [EASA] AD retains the 
requirements of DGAC France AD F-2006-016, which is superseded, but 
requires the accomplishment of repetitive SDI to replace the 
previously required ultrasonic inspections [and related 
investigative actions and corrective actions if necessary].

    Related investigative actions include an ultrasonic inspection for 
cracking on the forward face of forward fitting and a detailed 
inspection for cracking of the aft fitting around the fasteners. 
Corrective actions include crack repairs, modification of the sealing 
fittings and sealing shims. This proposed AD requires reporting of the 
inspection results to Airbus. 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-2017-0520.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Airbus Service Bulletin A300-53-0246, Revision 
08, including Appendix 1, dated April 13, 2016 (for Model A300 series 
airplanes); and Airbus Service Bulletin A300-53-6029, Revision 12, 
including Appendix 1, dated April 13, 2016 (for Model A300-600 series 
airplanes). The service information describes procedures for doing an 
SDI for cracking of the FR 47 forward fitting upper radius on the left-
hand and right-hand sides of the fuselage, and related investigative 
actions and corrective actions. This service information is reasonably 
available because the interested parties have access to it through 
their normal course of business or by the means identified in the 
ADDRESSES section.

[[Page 24904]]

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 designs.
    This NPRM would not supersede AD 2007-26-14, Amendment 39-15316 (73 
FR 2803, January 16, 2008). Rather, we have determined that a stand-
alone AD would be more appropriate to address the changes in the MCAI. 
This NPRM would require repetitive inspections to detect cracking of 
the upper radius of the forward fitting of FR 47, and related 
investigative actions and corrective actions if necessary. 
Accomplishment of the proposed actions would then terminate all 
requirements of AD 2007-26-14 for the inspected airplane.

Differences Between This Proposed AD and the MCAI or Service 
Information

    Although the MCAI and service information allow further flight if 
cracks are found during accomplishment of the required action, this 
proposed AD requires that any cracking be repaired before further 
flight.

Costs of Compliance

    We estimate that this proposed AD affects 132 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

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

    We estimate the following costs to do any necessary related 
investigative and corrective actions that would be required based on 
the results of the proposed inspection. We have no way of determining 
the number of airplanes that might need these repairs:

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 proposed AD 
is 2120-0056. The paperwork cost associated with this proposed AD 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 proposed AD 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.

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.

abnormal load event, such as hard landing or flight in excessive 
turbulence, occurred within 3 months before the effective date of 
this AD or occurs on or after the effective date of this AD: Within 
3 months after each event, accomplish an SDI for cracking of the FR 
47 forward fitting upper radius, left-hand and right-hand sides of 
the fuselage, in accordance with the applicable Accomplishment 
Instructions of the Airbus service information specified in 
paragraphs (g)(1) or (g)(2) of this AD. If, during this 3-month
