Discussion On December 19, 2014, we issued AD 2014–26–10, Amendment 39–18061 (80 FR 2813, January 21, 2015) (‘‘AD 2014– 26–10’’), for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2014–26–10 was prompted by a determination that the maintenance actions for airplane systems susceptible to aging must be mandated. AD 2014– 26–10 requires revising the maintenance or inspection program to incorporate maintenance requirements and airworthiness limitations. We issued AD 2014–26–10 to mitigate the risks associated with aging effects of airplane systems. Such aging effects could change the characteristics of the systems leading to an increased potential for failure, which could result in failure of certain life-limited parts, and reduced structural integrity or reduced controllability of the airplane. Since we issued AD 2014–26–10, we have determined that more restrictive maintenance instructions and airworthiness limitations are necessary. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016–0093, dated May 13, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the E:\FR\FM\13APP1.SGM 13APP1 Federal Register / Vol. 82, No. 70 / Thursday, April 13, 2017 / Proposed Rules MCAI’’), to correct an unsafe condition for all Airbus Model A318, A319, A320, and A321 series airplanes. The MCAI states: The airworthiness limitations for Airbus A320 family aeroplanes are currently defined and published in Airbus A318/A319/A320/ A321 Airworthiness Limitations Section (ALS) documents. The airworthiness limitations applicable to the System Equipment Maintenance Requirements, which are approved by [European Aviation Safety Agency] EASA, are specified in ALS Part 4. The instructions contained in the ALS Part 4 have been identified as mandatory actions for continued airworthiness. Failure to comply with these instructions could result in an unsafe condition. Previously, EASA issued AD 2013–0146 [which corresponds to FAA AD 2014–26–10] to require accomplishment of all maintenance actions as described in ALS Part 4 at Revision 01. The new ALS Part 4 Revision 03 (hereafter referred to as ‘the ALS’ in this AD) includes new and/or more restrictive requirements. ALS Part 4 Revision 03, issue 02, has been released to include editorial changes. For the reason described above, this [EASA] AD retains the requirements of EASA AD 2013–0146, which is superseded, and requires accomplishment of the actions specified in the ALS. 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–2017– 0248. nlaroche on DSK30NT082PROD with PROPOSALS Related Service Information Under 1 CFR Part 51 Airbus has issued Airbus A318/A319/ A320/A321 ALS Part 4, ‘‘System Equipment Maintenance Requirements (SEMR)’’ Revision 03 at Issue 02, dated January 22, 2016. The service information describes preventative maintenance requirements and includes updated inspections and intervals to be incorporated into the maintenance or inspection program. 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. 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 VerDate Sep<11>2014 14:43 Apr 12, 2017 Jkt 241001 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 inspections that will ensure the continued operational safety of the airplane. Differences Between This Proposed AD and the MCAI or Service Information The EASA AD specifies that if there are findings from the ALS inspection tasks, then corrective action must be accomplished in accordance with Airbus maintenance documentation. However, this proposed AD does not include that requirement because operators of U.S.-registered airplanes are required by general airworthiness and operational regulations to use FAAacceptable methods when performing maintenance. We consider those methods to be adequate to address any corrective actions necessitated by the findings of ALS inspections required by this proposed AD. Although the EASA AD recommends accomplishing the tasks specified in the ALS after the effective date of the EASA AD, and revising the maintenance program within 12 months after the effective date of the EASA AD, this proposed AD would only require revising the maintenance or inspection program within 30 days after the effective date of this AD, which correlates with the compliance time required by AD 2014–26–10. In developing an appropriate compliance time for this proposed AD, we considered the degree of urgency associated with the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to perform the revision (1 work-hour). In light of these factors, we find that a 30day compliance time represents an appropriate interval of time for affected airplanes to continue to operate without compromising safety. These differences have been coordinated with the EASA and Airbus. PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 17771 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 14 CFR 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/ 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 the airplanes identified in E:\FR\FM\13APP1.SGM 13APP1 17772 Federal Register / Vol. 82, No. 70 / Thursday, April 13, 2017 / Proposed Rules paragraph (c) of this AD 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 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 1,032 airplanes of U.S. registry. The actions required by AD 2014–26– 10, and retained in this proposed AD take about 1 work-hour per product, at an average labor rate of $85 per workhour. Based on these figures, the estimated cost of the actions that are required by AD 2014–26–10 is $85 per product. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $87,720, or $85 per product. nlaroche on DSK30NT082PROD 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: 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 VerDate Sep<11>2014 14:43 Apr 12, 2017 Jkt 241001 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: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2014–26–10, Amendment 39–18061 (80 FR 2813, January 21, 2015), and adding the following new AD: ■ Airbus: Docket No. FAA–2017–0248; Directorate Identifier 2016–NM–088–AD.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2014-26-
10, for all Airbus Model A318, A319, A320, and A321 series airplanes. 
AD 2014-26-10 currently requires revising the maintenance or inspection 
program to incorporate maintenance requirements and airworthiness 
limitations. Since we issued AD 2014-26-10, we have determined that 
more restrictive maintenance instructions and airworthiness limitations 
are necessary. This proposed AD would require revising the maintenance 
or inspection program, as applicable, to incorporate new or revised 
airworthiness limitation requirements. This proposed AD also removes 
airplanes from the applicability. We are proposing this AD to address

Discussion

    On December 19, 2014, we issued AD 2014-26-10, Amendment 39-18061 
(80 FR 2813, January 21, 2015) (``AD 2014-26-10''), for all Airbus 
Model A318, A319, A320, and A321 series airplanes. AD 2014-26-10 was 
prompted by a determination that the maintenance actions for airplane 
systems susceptible to aging must be mandated. AD 2014-26-10 requires 
revising the maintenance or inspection program to incorporate 
maintenance requirements and airworthiness limitations. We issued AD 
2014-26-10 to mitigate the risks associated with aging effects of 
airplane systems. Such aging effects could change the characteristics 
of the systems leading to an increased potential for failure, which 
could result in failure of certain life-limited parts, and reduced 
structural integrity or reduced controllability of the airplane.
    Since we issued AD 2014-26-10, we have determined that more 
restrictive maintenance instructions and airworthiness limitations are 
necessary.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0093, dated May 13, 2016 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the

[[Page 17771]]

MCAI''), to correct an unsafe condition for all Airbus Model A318, 
A319, A320, and A321 series airplanes. The MCAI states:

    The airworthiness limitations for Airbus A320 family aeroplanes 
are currently defined and published in Airbus A318/A319/A320/A321 
Airworthiness Limitations Section (ALS) documents. The airworthiness 
limitations applicable to the System Equipment Maintenance 
Requirements, which are approved by [European Aviation Safety 
Agency] EASA, are specified in ALS Part 4.
    The instructions contained in the ALS Part 4 have been 
identified as mandatory actions for continued airworthiness. Failure 
to comply with these instructions could result in an unsafe 
condition.
    Previously, EASA issued AD 2013-0146 [which corresponds to FAA 
AD 2014-26-10] to require accomplishment of all maintenance actions 
as described in ALS Part 4 at Revision 01. The new ALS Part 4 
Revision 03 (hereafter referred to as `the ALS' in this AD) includes 
new and/or more restrictive requirements. ALS Part 4 Revision 03, 
issue 02, has been released to include editorial changes.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2013-0146, which is superseded, and requires 
accomplishment of the actions specified in the ALS.

    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-2017-
0248.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Airbus A318/A319/A320/A321 ALS Part 4, ``System 
Equipment Maintenance Requirements (SEMR)'' Revision 03 at Issue 02, 
dated January 22, 2016. The service information describes preventative 
maintenance requirements and includes updated inspections and intervals 
to be incorporated into the maintenance or inspection program. 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.

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 inspections that will ensure the continued 
operational safety of the airplane.

Differences Between This Proposed AD and the MCAI or Service 
Information

    The EASA AD specifies that if there are findings from the ALS 
inspection tasks, then corrective action must be accomplished in 
accordance with Airbus maintenance documentation. However, this 
proposed AD does not include that requirement because operators of 
U.S.-registered airplanes are required by general airworthiness and 
operational regulations to use FAA-acceptable methods when performing 
maintenance. We consider those methods to be adequate to address any 
corrective actions necessitated by the findings of ALS inspections 
required by this proposed AD.
    Although the EASA AD recommends accomplishing the tasks specified 
in the ALS after the effective date of the EASA AD, and revising the 
maintenance program within 12 months after the effective date of the 
EASA AD, this proposed AD would only require revising the maintenance 
or inspection program within 30 days after the effective date of this 
AD, which correlates with the compliance time required by AD 2014-26-
10. In developing an appropriate compliance time for this proposed AD, 
we considered the degree of urgency associated with the subject unsafe 
condition, the average utilization of the affected fleet, and the time 
necessary to perform the revision (1 work-hour). In light of these 
factors, we find that a 30-day compliance time represents an 
appropriate interval of time for affected airplanes to continue to 
operate without compromising safety.
    These differences have been coordinated with the EASA and Airbus.

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 14 CFR 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/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 the airplanes identified 
in

[[Page 17772]]

paragraph (c) of this AD 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 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 1,032 airplanes of U.S. 
registry.
    The actions required by AD 2014-26-10, and retained in this 
proposed AD take about 1 work-hour per product, at an average labor 
rate of $85 per work-hour. Based on these figures, the estimated cost 
of the actions that are required by AD 2014-26-10 is $85 per product.
    We also estimate that it would take about 1 work-hour per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $87,720, or $85 
per product.

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.

List of Subjects in 14 CFR Part 39
