Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent E:\FR\FM\08MYP1.SGM 08MYP1 Federal Register / Vol. 83, No. 89 / Tuesday, May 8, 2018 / Proposed Rules for the Member States of the European Union, has issued EASA Airworthiness Directive 2017–0222R1, dated December 15, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for ATR–GIE ´ Avions de Transport Regional Model ATR42–500 airplanes. The MCAI states: sradovich on DSK3GMQ082PROD with PROPOSALS The airworthiness limitations and certification maintenance requirements (CMR) for ATR aeroplanes, which are approved by EASA, are currently defined and published in the ATR42–400/–500 Time Limits (TL) document. These instructions have been identified as mandatory for continued airworthiness. Failure to accomplish these instructions could result in an unsafe condition [i.e., reduced structural integrity of the airplane]. Consequently, ATR published Revision 11 Temporary revision 01 of the ATR42–400/– 500 TL document, which contains new and/ or more restrictive CMRs and airworthiness limitations tasks. For the reasons described above, this [EASA] AD requires accomplishment of the actions specified in the ATR42–400/–500 TL document Revision 11 Temporary revision 01, hereafter referred to as ‘the TLD’ in this [EASA] AD. This [EASA] AD, in conjunction with two other [EASA] ADs related to ATR42–200/– 300/–320 (EASA AD 2017–0221) and ATR72–101/–102/–201/–202/–211/–212/– 212A (EASA AD 2017–0223) aeroplanes, retains the requirements of EASA AD 2009– 0242 [which corresponds to FAA AD 2008– 04–19 R1, Amendment 39–16069 (74 FR 56713, November 3, 2009)] and EASA AD 2012–0193 [which corresponds to FAA AD 2015–26–09, Amendment 39–18357 (81 FR 1483, January 13, 2016)]. Once all these three [EASA] ADs are effective, EASA will cancel EASA AD 2009–0242 and EASA AD 2012– 0193. This [EASA] AD is revised to provide the correct issue date (03 May 2017) of the TLD. The original [EASA] AD inadvertently referenced the EASA approval date for that document. The required actions include revising the maintenance or inspection program, as applicable, to incorporate new and/ or more restrictive maintenance requirements and airworthiness limitations. The unsafe condition is reduced structural integrity 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– 0366. Relationship Between Proposed AD and Certain Other ADs This NPRM would not supersede AD 2008–04–19 R1 and AD 2015–26–09. Rather, we have determined that a stand-alone AD would be more appropriate to address the changes in VerDate Sep<11>2014 16:44 May 07, 2018 Jkt 244001 the MCAI. This NPRM would require revising the maintenance or inspection program, as applicable. Accomplishment of the proposed actions would then terminate all requirements of AD 2008–04–19 R1 and AD 2015–26–09 for ATR–GIE Avions de ´ Transport Regional Model ATR42–500 airplanes only. In addition, we have determined that accomplishment of the proposed actions terminates all requirements of AD 2000– 23–04 R1, Amendment 39–12174 (66 FR 19381, April 16, 2001). Related Service Information Under 1 CFR Part 51 ATR–GIE Avions de Transport ´ Regional has issued ATR42–400/–500, Time Limits Document (TL), Revision 11, dated May 5, 2015. This service information describes life limits and maintenance requirements for the affected airplanes. ATR–GIE Avions de Transport ´ Regional has issued ATR42–400/–500 Temporary Revision TR01/17, dated May 3, 2017, to the ATR42–400/–500 Time Limits Document (TL). This service information describes changes to life limits and maintenance requirements of certain tasks for the affected airplanes. 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 the same type design. 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 PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 20749 paragraph (k)(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 airworthiness limitations section (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. Airworthiness Limitations Based on Type Design The FAA recently became aware of an issue related to the applicability of ADs that require incorporation of an ALS revision into an operator’s maintenance or inspection program. Typically, when these types of ADs are issued by civil aviation authorities of other countries, they apply to all airplanes covered under an identified type certificate (TC). The corresponding FAA AD typically retains applicability to all of those airplanes. In addition, U.S. operators must operate their airplanes in an airworthy condition, in accordance with 14 CFR 91.7(a). Included in this obligation is the requirement to perform any maintenance or inspections specified in the ALS, and in accordance with the ALS as specified in 14 CFR 43.16 and 91.403(c), unless an alternative has been approved by the FAA. When a type certificate is issued for a type design, the specific ALS, including revisions, is a part of that type design, as specified in 14 CFR 21.31(c). The sum effect of these operational and maintenance requirements is an obligation to comply with the ALS defined in the type design referenced in the manufacturer’s conformity statement. This obligation may introduce a conflict with an AD that requires a specific ALS revision if new airplanes are delivered with a later revision as part of their type design. To address this conflict, the FAA has approved alternative methods of compliance (AMOCs) that allow operators to incorporate the most recent ALS revision into their maintenance/ E:\FR\FM\08MYP1.SGM 08MYP1 20750 Federal Register / Vol. 83, No. 89 / Tuesday, May 8, 2018 / Proposed Rules sradovich on DSK3GMQ082PROD with PROPOSALS inspection programs, in lieu of the ALS revision required by the AD. This eliminates the conflict and enables the operator to comply with both the AD and the type design. However, compliance with AMOCs is normally optional, and we recently became aware that some operators choose to retain the AD-mandated ALS revision in their fleet-wide maintenance/inspection programs, including those for new airplanes delivered with later ALS revisions, to help standardize the maintenance of the fleet. To ensure that operators comply with the applicable ALS revision for newly delivered airplanes containing a later revision than that specified in an AD, we plan to limit the applicability of ADs that mandate ALS revisions to those airplanes that are subject to an earlier revision of the ALS, either as part of the type design or as mandated by an earlier AD. This proposed AD therefore would apply to ATR–GIE Avions de Transport ´ Regional Model ATR42–500 airplanes with an original certificate of airworthiness or original export certificate of airworthiness that was issued on or before the date of approval of the ALS temporary revision identified in this proposed AD. Operators of airplanes with an original certificate of airworthiness or original export certificate of airworthiness issued after that date must comply with the airworthiness limitations specified as part of the approved type design and referenced on the type certificate data sheet. Costs of Compliance We estimate that this proposed AD affects 4 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 this figure 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 × $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: VerDate Sep<11>2014 16:44 May 07, 2018 Jkt 244001 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. 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: PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 PART 39—AIRWORTHINESS DIRECTIVES 1.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent

[[Page 20749]]

for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2017-0222R1, dated December 15, 2017 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for ATR-GIE Avions de 
Transport R[eacute]gional Model ATR42-500 airplanes. The MCAI states:

    The airworthiness limitations and certification maintenance 
requirements (CMR) for ATR aeroplanes, which are approved by EASA, 
are currently defined and published in the ATR42-400/-500 Time 
Limits (TL) document. These instructions have been identified as 
mandatory for continued airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition [i.e., reduced structural integrity of the 
airplane].
    Consequently, ATR published Revision 11 Temporary revision 01 of 
the ATR42-400/-500 TL document, which contains new and/or more 
restrictive CMRs and airworthiness limitations tasks.
    For the reasons described above, this [EASA] AD requires 
accomplishment of the actions specified in the ATR42-400/-500 TL 
document Revision 11 Temporary revision 01, hereafter referred to as 
`the TLD' in this [EASA] AD.
    This [EASA] AD, in conjunction with two other [EASA] ADs related 
to ATR42-200/-300/-320 (EASA AD 2017-0221) and ATR72-101/-102/-201/-
202/-211/-212/-212A (EASA AD 2017-0223) aeroplanes, retains the 
requirements of EASA AD 2009-0242 [which corresponds to FAA AD 2008-
04-19 R1, Amendment 39-16069 (74 FR 56713, November 3, 2009)] and 
EASA AD 2012-0193 [which corresponds to FAA AD 2015-26-09, Amendment 
39-18357 (81 FR 1483, January 13, 2016)]. Once all these three 
[EASA] ADs are effective, EASA will cancel EASA AD 2009-0242 and 
EASA AD 2012-0193.
    This [EASA] AD is revised to provide the correct issue date (03 
May 2017) of the TLD. The original [EASA] AD inadvertently 
referenced the EASA approval date for that document.

    The required actions include revising the maintenance or inspection 
program, as applicable, to incorporate new and/or more restrictive 
maintenance requirements and airworthiness limitations. The unsafe 
condition is reduced structural integrity 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-
0366.

Relationship Between Proposed AD and Certain Other ADs

    This NPRM would not supersede AD 2008-04-19 R1 and AD 2015-26-09. 
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. 
Accomplishment of the proposed actions would then terminate all 
requirements of AD 2008-04-19 R1 and AD 2015-26-09 for ATR-GIE Avions 
de Transport R[eacute]gional Model ATR42-500 airplanes only.
    In addition, we have determined that accomplishment of the proposed 
actions terminates all requirements of AD 2000-23-04 R1, Amendment 39-
12174 (66 FR 19381, April 16, 2001).

Related Service Information Under 1 CFR Part 51

    ATR-GIE Avions de Transport R[eacute]gional has issued ATR42-400/-
500, Time Limits Document (TL), Revision 11, dated May 5, 2015. This 
service information describes life limits and maintenance requirements 
for the affected airplanes.
    ATR-GIE Avions de Transport R[eacute]gional has issued ATR42-400/-
500 Temporary Revision TR01/17, dated May 3, 2017, to the ATR42-400/-
500 Time Limits Document (TL). This service information describes 
changes to life limits and maintenance requirements of certain tasks 
for the affected airplanes.
    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 the same 
type design.
    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 
(k)(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 
airworthiness limitations section (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.

Airworthiness Limitations Based on Type Design

    The FAA recently became aware of an issue related to the 
applicability of ADs that require incorporation of an ALS revision into 
an operator's maintenance or inspection program.
    Typically, when these types of ADs are issued by civil aviation 
authorities of other countries, they apply to all airplanes covered 
under an identified type certificate (TC). The corresponding FAA AD 
typically retains applicability to all of those airplanes.
    In addition, U.S. operators must operate their airplanes in an 
airworthy condition, in accordance with 14 CFR 91.7(a). Included in 
this obligation is the requirement to perform any maintenance or 
inspections specified in the ALS, and in accordance with the ALS as 
specified in 14 CFR 43.16 and 91.403(c), unless an alternative has been 
approved by the FAA.
    When a type certificate is issued for a type design, the specific 
ALS, including revisions, is a part of that type design, as specified 
in 14 CFR 21.31(c).
    The sum effect of these operational and maintenance requirements is 
an obligation to comply with the ALS defined in the type design 
referenced in the manufacturer's conformity statement. This obligation 
may introduce a conflict with an AD that requires a specific ALS 
revision if new airplanes are delivered with a later revision as part 
of their type design.
    To address this conflict, the FAA has approved alternative methods 
of compliance (AMOCs) that allow operators to incorporate the most 
recent ALS revision into their maintenance/

[[Page 20750]]

inspection programs, in lieu of the ALS revision required by the AD. 
This eliminates the conflict and enables the operator to comply with 
both the AD and the type design.
    However, compliance with AMOCs is normally optional, and we 
recently became aware that some operators choose to retain the AD-
mandated ALS revision in their fleet-wide maintenance/inspection 
programs, including those for new airplanes delivered with later ALS 
revisions, to help standardize the maintenance of the fleet. To ensure 
that operators comply with the applicable ALS revision for newly 
delivered airplanes containing a later revision than that specified in 
an AD, we plan to limit the applicability of ADs that mandate ALS 
revisions to those airplanes that are subject to an earlier revision of 
the ALS, either as part of the type design or as mandated by an earlier 
AD.
    This proposed AD therefore would apply to ATR-GIE Avions de 
Transport R[eacute]gional Model ATR42-500 airplanes with an original 
certificate of airworthiness or original export certificate of 
airworthiness that was issued on or before the date of approval of the 
ALS temporary revision identified in this proposed AD. Operators of 
airplanes with an original certificate of airworthiness or original 
export certificate of airworthiness issued after that date must comply 
with the airworthiness limitations specified as part of the approved 
type design and referenced on the type certificate data sheet.

Costs of Compliance

    We estimate that this proposed AD affects 4 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 this 
figure 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 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.
