Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2017–0202, dated October 12, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus 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), and Model A310 series airplanes. The MCAI states: Maintenance requirements and airworthiness limitations for the Airbus E:\FR\FM\08MYP1.SGM 08MYP1 20744 Federal Register / Vol. 83, No. 89 / Tuesday, May 8, 2018 / Proposed Rules A310, A300–600 and A300–600ST family aeroplanes, which are approved by EASA, are currently defined and published in the Airbus A310 and A300–600 Airworthiness Limitations Section (ALS) documents. The System Equipment Maintenance Requirements (SEMR) for the Airbus A310 and A300–600, are specified in the Airbus A310 and Airbus A300–600 (including A300–600ST) ALS Part 4 documents. These instructions have been identified as mandatory for continuing airworthiness. Failure to accomplish these instructions could result in an unsafe condition. EASA previously issued AD 2013–0075 [which corresponds to FAA AD 2015–02–16, Amendment 39–18083 (80 FR 5028, January 30, 2015) (‘‘AD 2015–02–16’’)] to require the implementation of the maintenance requirements and associated airworthiness limitations as specified in Airbus A310 and A300–600 ALS Part 4 documents at Revision 02. Since that [EASA] AD was issued, new or more restrictive maintenance requirements and airworthiness limitations were approved by EASA. Consequently, Airbus published Revision 03 of A310 and A300–600 ALS Part 4 documents, compiling all ALS Part 4 changes approved since previous Revision 02. For the reasons described above, this new [EASA] AD retains the requirements of EASA AD 2013–0075, which is superseded, and requires the implementation of the actions specified in Airbus A310 ALS Part 4 Revision 03 and Airbus A300–600 ALS Part 4 Revision 03. sradovich on DSK3GMQ082PROD with PROPOSALS We are proposing this AD to mitigate the risks associated with the effects of aging on airplane systems. Such effects could change system characteristics, leading to an increased potential for failure of certain life-limited parts, and reduced structural integrity or controllability of the airplane. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0396. Relationship of Proposed AD to AD 2015–02–16 This NPRM would not supersede AD 2015–02–16. Rather, we have determined that a stand-alone AD would be more appropriate to address the changes in the MCAI. This NPRM would require revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations. Accomplishment of the proposed actions would then terminate all requirements of AD 2015–02–16. Related Service Information Under 1 CFR Part 51 Airbus has issued A310 Airworthiness Limitations Section VerDate Sep<11>2014 16:44 May 07, 2018 Jkt 244001 (ALS) Part 4, ‘‘System Equipment Maintenance Requirements (SEMR),’’ Revision 03, dated August 28, 2017; and A300–600 Airworthiness Limitations Section (ALS) Part 4, ‘‘System Equipment Maintenance Requirements (SEMR),’’ Revision 03, dated August 28, 2017. This service information describes the revision of the maintenance or inspection program, as applicable, to incorporate new maintenance requirements and airworthiness limitations. These documents are distinct since they apply to different airplane models. 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. 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 these same type designs. This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (j)(1) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane. Differences Between This Proposed AD and the MCAI or Service Information The MCAI specifies that if there are findings from the ALS inspection tasks, corrective actions must be accomplished in accordance with Airbus maintenance documentation. However, this proposed AD does not include that requirement. Operators of U.S.-registered airplanes are required by general airworthiness and operational regulations to perform maintenance using methods that are PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 acceptable to the FAA. We consider those methods to be adequate to address any corrective actions necessitated by the findings of ALS inspections required by this proposed AD. Costs of Compliance We estimate that this proposed AD affects 127 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: We have determined that revising the maintenance or inspection program takes an average of 90 work-hours per operator, although we recognize that this number may vary from operator to operator. In the past, we have estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), we have determined that a per-operator estimate is more accurate than a perairplane estimate. Therefore, we estimate the total cost per operator to be $7,650 (90 work-hours × $85 per workhour). 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 E:\FR\FM\08MYP1.SGM 08MYP1 Federal Register / Vol. 83, No. 89 / Tuesday, May 8, 2018 / Proposed Rules 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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2017-0202, dated October 12, 2017 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus 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), and Model A310 series airplanes. The MCAI states:

    Maintenance requirements and airworthiness limitations for the 
Airbus

[[Page 20744]]

A310, A300-600 and A300-600ST family aeroplanes, which are approved 
by EASA, are currently defined and published in the Airbus A310 and 
A300-600 Airworthiness Limitations Section (ALS) documents. The 
System Equipment Maintenance Requirements (SEMR) for the Airbus A310 
and A300-600, are specified in the Airbus A310 and Airbus A300-600 
(including A300-600ST) ALS Part 4 documents. These instructions have 
been identified as mandatory for continuing airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition.
    EASA previously issued AD 2013-0075 [which corresponds to FAA AD 
2015-02-16, Amendment 39-18083 (80 FR 5028, January 30, 2015) (``AD 
2015-02-16'')] to require the implementation of the maintenance 
requirements and associated airworthiness limitations as specified 
in Airbus A310 and A300-600 ALS Part 4 documents at Revision 02.
    Since that [EASA] AD was issued, new or more restrictive 
maintenance requirements and airworthiness limitations were approved 
by EASA. Consequently, Airbus published Revision 03 of A310 and 
A300-600 ALS Part 4 documents, compiling all ALS Part 4 changes 
approved since previous Revision 02.
    For the reasons described above, this new [EASA] AD retains the 
requirements of EASA AD 2013-0075, which is superseded, and requires 
the implementation of the actions specified in Airbus A310 ALS Part 
4 Revision 03 and Airbus A300-600 ALS Part 4 Revision 03.

    We are proposing this AD to mitigate the risks associated with the 
effects of aging on airplane systems. Such effects could change system 
characteristics, leading to an increased potential for failure of 
certain life-limited parts, and reduced structural integrity or 
controllability of the airplane. You may examine the MCAI in the AD 
docket on the internet at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2018-0396.

Relationship of Proposed AD to AD 2015-02-16

    This NPRM would not supersede AD 2015-02-16. Rather, we have 
determined that a stand-alone AD would be more appropriate to address 
the changes in the MCAI. This NPRM would require revising the 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive maintenance requirements and airworthiness 
limitations. Accomplishment of the proposed actions would then 
terminate all requirements of AD 2015-02-16.

dated August 28, 2017; and A300-600 Airworthiness Limitations Section 
(ALS) Part 4, ``System Equipment Maintenance Requirements (SEMR),'' 
Revision 03, dated August 28, 2017. This service information describes 
the revision of the maintenance or inspection program, as applicable, 
to incorporate new maintenance requirements and airworthiness 
limitations. These documents are distinct since they apply to different 
airplane models. 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.

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 these 
same type designs.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(j)(1) of this proposed AD. The request should include a description of 
changes to the required actions that will ensure the continued 
operational safety of the airplane.

Differences Between This Proposed AD and the MCAI or Service 
Information

    The MCAI specifies that if there are findings from the ALS 
inspection tasks, corrective actions must be accomplished in accordance 
with Airbus maintenance documentation. However, this proposed AD does 
not include that requirement. Operators of U.S.-registered airplanes 
are required by general airworthiness and operational regulations to 
perform maintenance using methods that are acceptable to the FAA. We 
consider those methods to be adequate to address any corrective actions 
necessitated by the findings of ALS inspections required by this 
proposed AD.

Costs of Compliance

    We estimate that this proposed AD affects 127 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:
    We have determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although we 
recognize that this number may vary from operator to operator. In the 
past, we have estimated that this action takes 1 work-hour per 
airplane. Since operators incorporate maintenance or inspection program 
changes for their affected fleet(s), we have determined that a per-
operator estimate is more accurate than a per-airplane estimate. 
Therefore, we estimate the total cost per operator to be $7,650 (90 
work-hours x $85 per work-hour).

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

[[Page 20745]]

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.

List of Subjects in 14 CFR Part 39
