Download as PDF 25810 Federal Register / Vol. 86, No. 89 / Tuesday, May 11, 2021 / Proposed Rules DHS further believes that continuing to administer the IE parole program, in accordance with 8 CFR 212.19, and withdrawing the May 2018 NPRM, is consistent with the Administration’s goal of better ensuring that all avenues available under the law remain viable options for those seeking to come to the United States, including qualified entrepreneurs who would substantially benefit the United States by growing new businesses and creating jobs for U.S. workers. Therefore, for all the reasons discussed above, DHS is withdrawing the May 29, 2018, NPRM that would have removed the IE parole program from DHS regulations.

Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0274, dated December 10, 2020 (EASA AD 2020–0274) (also referred to as the E:\FR\FM\11MYP1.SGM 11MYP1 Federal Register / Vol. 86, No. 89 / Tuesday, May 11, 2021 / Proposed Rules Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all: • Airbus SAS Model A318–111, –112, –121, and –122 airplanes; • Airbus SAS Model A319–111, –112, –113, –114, –115, –131, –132, –133, –151N, –153N, and –171N airplanes; • Airbus SAS Model A320–211, –212, –214, –215, –216, –231, –232, –233, –251N, –252N, –253N, –271N, –272N, and –273N airplanes; • Airbus SAS Model A321–111, –112, –131, –211, –212, –213, –231, –232, –251N, –251NX, –252N, –252NX, –253N, –253NX, –271N, –271NX, –272N, and –272NX airplanes; • Airbus SAS Model A330–201, –202, –203, –223, –223F, –243, –243F, –301, –302, –303, –321, –322, –323, –341, –342, –343, –743L, –841, and –941 airplanes; • Airbus SAS Model A340–211, –212, –213, –311, –312, –313, –541, –542 –642, and –643 airplanes; and • Airbus SAS Model A380–841, –842, and –861 airplanes. Airbus SAS Model A320–215, A330– 743L, A340–542, and A340–643 airplanes are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability. This proposed AD was prompted by a report that repetitive disconnection and reconnection of certain Ni-Cd batteries during airplane parking or storage could lead to a reduction in capacity of those batteries. The FAA is proposing this AD to address reduced capacity of certain Ni-Cd batteries, which could lead to reduced battery endurance performance and possibly result in failure to supply the minimum essential electrical power during abnormal or emergency conditions. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2020–0274 describes procedures for replacing certain affected Ni-Cd batteries with serviceable Ni-Cd batteries, or maintaining the electrical storage capacity of those Ni-Cd batteries during airplane storage or parking. This material 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 the FAA’s bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is proposing this AD because the FAA evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 2020–0274 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD. Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD 25811 process, the FAA initially worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities (CAAs) to use this process. As a result, EASA AD 2020–0274 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2020–0274 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in the EASA AD does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required actions and compliance times,’’ compliance with this AD requirement is not limited to the section titled ‘‘Required Action(s) and Compliance Time(s)’’ in the EASA AD. Service information specified in EASA AD 2020–0274 that is required for compliance with EASA AD 2020–0274 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0350 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD affects 1,814 airplanes of U.S. registry. The FAA estimates 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 5 work-hours × $85 per hour = $425 .......................................................................................... $0 $425 $770,950 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. The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section VerDate Sep<11>2014 16:39 May 10, 2021 Jkt 253001 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. PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 Regulatory Findings The FAA 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. E:\FR\FM\11MYP1.SGM 11MYP1 25812 Federal Register / Vol. 86, No. 89 / Tuesday, May 11, 2021 / Proposed Rules For the reasons discussed above, I certify this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

     Airbus SAS Model A340-211, -212, -213, -311, -312, -313, -
541, -542 -642, and -643 airplanes; and
     Airbus SAS Model A380-841, -842, and -861 airplanes.
    Airbus SAS Model A320-215, A330-743L, A340-542, and A340-643 
airplanes are not certificated by the FAA and are not included on the 
U.S. type certificate data sheet; this AD therefore does not include 
those airplanes in the applicability.
    This proposed AD was prompted by a report that repetitive 
disconnection and reconnection of certain Ni-Cd batteries during 
airplane parking or storage could lead to a reduction in capacity of 
those batteries. The FAA is proposing this AD to address reduced 
capacity of certain Ni-Cd batteries, which could lead to reduced 
battery endurance performance and possibly result in failure to supply 
the minimum essential electrical power during abnormal or emergency 
conditions. See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0274 describes procedures for replacing certain 
affected Ni-Cd batteries with serviceable Ni-Cd batteries, or 
maintaining the electrical storage capacity of those Ni-Cd batteries 
during airplane storage or parking.
    This material 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 the FAA's bilateral agreement with the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is proposing this AD because the FAA 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop in other 
products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2020-0274 described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2020-0274 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2020-0274 in its 
entirety, through that incorporation, except for any differences 
identified as exceptions in the regulatory text of this proposed AD. 
Using common terms that are the same as the heading of a particular 
section in the EASA AD does not mean that operators need comply only 
with that section. For example, where the AD requirement refers to 
``all required actions and compliance times,'' compliance with this AD 
requirement is not limited to the section titled ``Required Action(s) 
and Compliance Time(s)'' in the EASA AD. Service information specified 
in EASA AD 2020-0274 that is required for compliance with EASA AD 2020-
0274 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2021-0350 after the FAA 
final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 1,814 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

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.
    The FAA is 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

    The FAA 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.

[[Page 25812]]

    For the reasons discussed above, I certify this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would 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.

(d) Subject

    Air Transport Association (ATA) of America Code 24, Electrical 
Power.

(e) Reason

    This AD was prompted by a report that repetitive disconnection 
and reconnection of certain nickel-cadmium (Ni-Cd) batteries during 
airplane parking or storage could lead to a reduction in capacity of 
those batteries. The FAA is issuing this AD to address reduced 
capacity of certain Ni-Cd batteries, which could lead to reduced 
battery endurance performance and possibly result in failure to 
supply the minimum essential electrical power during abnormal or 
emergency conditions.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, European Union Aviation Safety Agency (EASA) AD 
2020-0274, dated December 10, 2020 (EASA AD 2020-0274).

(h) Exceptions to EASA AD 2020-0274

    (1) Where EASA AD 2020-0274 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) Where EASA AD 2020-0274 defines a ``reconnection cycle'' as 
``repeated disconnection and connection of a battery . . .'' this AD 
defines it as ``one instance of disconnection and connection of a 
battery. . . .''
    (3) The ``Remarks'' section of EASA AD 2020-0274 does not apply 
to this AD.

(i) No Reporting Requirement

    Although the service information referenced in EASA AD 2020-0274 
specifies to submit certain information to the manufacturer, this AD 
does not include that requirement.

(j) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Large Aircraft Section, International Validation Branch, FAA, has 
the authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or responsible Flight 
Standards Office, as appropriate. If sending information directly to 
the Large Aircraft Section, International Validation Branch, send it 
to the attention of the person identified in paragraph (k)(2) of 
this AD. Information may be emailed to: [email protected]. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
responsible Flight Standards Office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, Large Aircraft 
Section, International Validation Branch, FAA; or EASA; or Airbus 
SAS's EASA Design Organization Approval (DOA). If approved by the 
DOA, the approval must include the DOA-authorized signature.
    (3) Required for Compliance (RC): Except as required by 
paragraph (j)(2) of this AD, if any service information referenced 
in EASA AD 2020-0274 that contains paragraphs that are labeled as 
RC, the instructions in RC paragraphs, including subparagraphs under 
an RC paragraph, must be done to comply with this AD; any 
paragraphs, including subparagraphs under those paragraphs, that are 
not identified as RC are recommended. The instructions in 
paragraphs, including subparagraphs under those paragraphs, not 
identified as RC may be deviated from using accepted methods in 
accordance with the operator's maintenance or inspection program 
without obtaining approval of an AMOC, provided the instructions 
identified as RC can be done and the airplane can be put back in an 
airworthy condition. Any substitutions or changes to instructions 
identified as RC require approval of an AMOC.
