Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Airbus SAS Model A318 series airplanes; Model A319-111, A319-
112, A319-113, A319-114, A319-115, A319-131, A319-132, A319-133, A319-
151N, and A319-153N airplanes; Model A320 series airplanes; and Model 
A321 series airplanes. This proposed AD was prompted by the results of 
laboratory tests on non-rechargeable lithium batteries installed in 
emergency locator transmitters (ELT), which highlighted a lack of 
protection against certain currents that could lead to thermal runaway 
and a battery fire. This proposed AD would require modifying a certain 
ELT by installing a diode in the airplane circuit connecting the ELT 
battery, as specified in a European Union Aviation Safety Agency (EASA) 
AD, which will be incorporated by reference. The FAA is proposing this 
AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by November 
16, 2020.

comment period has closed if it is possible to do so without incurring 
expense or delay. The FAA may change this NPRM because of those 
comments.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to the 
person identified in the FOR FURTHER INFORMATION CONTACT section. Any 
commentary that the FAA receives which is not specifically designated 
as CBI will be placed in the public docket for this rulemaking.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0103, dated May 7, 2020; 
corrected May 8, 2020 (``EASA AD 2020-0103'') (also referred to as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A318-111, A318-
112, A318-121, A318-122 airplanes; Model A319-111, A319-112, A319-113, 
A319-114, A319-115, A319-131, A319-132, A319-133, A319-151N, and A319-
153N airplanes; Model A320-211, A320-212, A320-214, A320-215, A320-216, 
A320-231, A320-232, A320-233, A320-251N, A320-252N, A320-253N, A320-
271N, A320-272N, and A320-273N airplanes; and Model A321-111, A321-112, 
A321-131, A321-211, A321-212, A321-213, A321-231, A321-232, A321-251N, 
A321-252N, A321-253N, A321-271N, A321-272N, A321-251NX, A321-252NX, 
A321-253NX, A321-271NX, and A321-272NX airplanes. Model A320-215 
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 the results of laboratory tests on 
nonrechargeable lithium batteries installed in ELTs, which highlighted 
a

[[Page 61885]]

lack of protection against currents of 28 volts DC or 115 volts AC that 
could lead to thermal runaway and a battery fire. The FAA is proposing 
this AD to address this unsafe condition, which could result in local 
(temporary) fires and could result in damage to the airplane and injury 
to occupants. See the MCAI for additional background information.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2020-0103 describes procedures for modifying a certain ELT 
by installing a diode in the airplane circuit connecting the ELT 
battery.
    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 our 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 2020-0103 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 2020-0103 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2020-0103 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 2020-0103 that is required for compliance with EASA AD 2020-
0103 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2020-0900 after the FAA 
final rule is published.

Clarification of Maintenance Activities With an Affected Part

    EASA AD 2020-0103 defines an affected part as an ELT having part 
number (P/N) 01N65900. When the modification (installation of a diode) 
is completed, the part number of the ELT does not change. The intent of 
paragraph (1) of EASA AD 2020-0103 is to require, for airplanes that 
have an affected ELT installed, operators to do the modification within 
24 months. For these airplanes, operators can remove an ELT having P/N 
01N65900 and reinstall that same part during maintenance activities 
within the 24-month compliance for doing the modification. After the 
modification is done, operators can install an ELT having P/N 01N65900 
as long as the modification is not removed.

Costs of Compliance

    The FAA estimates that this proposed AD affects 1,100 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255...........................            $450             $705         $775,500
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected individuals. The FAA does not control warranty 
coverage for affected individuals. As a result, the FAA has included 
all known costs in our cost estimate.

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

(e) Reason

    This AD was prompted by the results of laboratory tests on non-
rechargeable lithium batteries installed in emergency locator 
transmitters (ELT), which highlighted a lack of protection against 
currents of 28 volts DC or 115 volts AC that could lead to thermal 
runaway and a battery fire. The FAA is issuing this AD to address 
this unsafe condition, which could result in local (temporary) 
fires, and could result in damage to the airplane and injury to 
occupants.

(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 
2020-0103, dated May 7, 2020; corrected May 8, 2020 (``EASA AD 2020-
0103'').

(h) Exceptions to EASA AD 2020-0103

    (1) Where EASA AD 2020-0103 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) The ``Remarks'' section of EASA AD 2020-0103 does not apply 
to this AD.
    (3) Where paragraph (3) of EASA AD 2020-0103 specifies the parts 
installation limitation, for this AD, comply with paragraph (i) of 
this AD.

(i) Parts Installation Limitation

N) 01N65900 installed as of the effective date of this AD: As of the 
effective date of this AD, no person may install an ELT having P/N 
01N65900 on any airplane unless the airplane has been modified as 
required by paragraph (1) of EASA AD 2020-0103.
    (2) For airplanes that have an ELT having P/N 01N65900 installed 
as of the effective date of this AD: After modification of the 
airplane as required by paragraph (1) of EASA AD 2020-0103, no 
person may install an ELT having P/N 01N65900 on that airplane if 
the modification is removed.

(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 local Flight
