Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A318, A319, A320, A321, A330-200, A330-200 Freighter, A330-300, A330-800, A330-900, A340-200, A340-300, A340-500, A340-600, and A380-800 series airplanes. This proposed AD was prompted by a determination that repetitive disconnection and reconnection of certain parts manufacturer approval (PMA) nickel-cadmium (Ni-Cd) batteries during airplane parking or storage could lead to a reduction in capacity of those batteries. This proposed AD would require replacing certain PMA Ni-Cd batteries with serviceable Ni-Cd batteries, or maintaining the electrical storage capacity of those PMA Ni-Cd batteries during airplane storage or parking. This proposed AD corresponds to a previously proposed AD on type design Ni-Cd batteries with the same unsafe condition on the same model airplanes. The FAA is proposing this AD to address the unsafe condition on these products.

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 certain Airbus SAS Model A318, A319, A320, A321, A330-200, A330-200
Freighter, A330-300, A330-800, A330-900, A340-200, A340-300, A340-500,
A340-600, and A380-800 series airplanes. This proposed AD was prompted
by a determination that repetitive disconnection and reconnection of
certain parts manufacturer approval (PMA) nickel-cadmium (Ni-Cd)
batteries during airplane parking or storage could lead to a reduction
in capacity of those batteries. This proposed AD would require
replacing certain PMA Ni-Cd batteries with serviceable Ni-Cd batteries,
or maintaining the electrical storage capacity of those PMA Ni-Cd
batteries during airplane storage or parking. This proposed AD
corresponds to a previously proposed AD on type design Ni-Cd batteries
with the same unsafe condition on the same model airplanes. 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 September
2, 2021.

Background
The FAA issued an NPRM, Docket Number FAA-2021-0350, which
published in the Federal Register on May 11, 2021 (86 FR 25810). The
NPRM addresses an unsafe condition for certain type design Ni-Cd
batteries on all Airbus SAS Model A318, A319, A320, A321, A330-200,
A330-200 Freighter, A330-300, A330-800, A330-900, A340-200, A340-300,
A340-500, A340-600, and A380-800 series airplanes. The NPRM corresponds
to European Union Aviation Safety Agency (EASA) AD 2020-0274, dated
December 10, 2020 (EASA AD 2020-0274). The NPRM was prompted by a
report that
[[Page 37937]]
repetitive disconnection and reconnection of certain Ni-Cd batteries
during airplane parking or storage could lead to a reduction in
capacity of those batteries.
PMA Ni-Cd batteries are similar in design to the type design Ni-Cd
batteries. The FAA has determined that any PMA part approved for the
type design Ni-Cd batteries identified in the May 11, 2021 NPRM are
also affected by the unsafe condition; therefore, this proposed AD
would apply to those PMA Ni-Cd batteries.
The FAA has determined that repetitive disconnection and
reconnection of certain PMA 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 PMA 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.
Related Service Information Under 1 CFR Part 51
Airbus has issued Alert Operators Transmission (AOT) A24N006-20,
dated September 9, 2020; AOT A24L007-20, dated September 23, 2020; and
AOT A24R009-20, dated September 23, 2020. This service information
describes procedures for maintaining the electrical storage capacity of
Ni-Cd batteries during airplane storage or parking. 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
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
and service information 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
on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require replacing certain PMA Ni-Cd
batteries with serviceable Ni-Cd batteries, or maintaining the
electrical storage capacity of those PMA Ni-Cd batteries during
airplane storage or parking.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect up to 1,814 airplanes of U.S. registry. The FAA estimates the
following costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per
Labor cost Parts cost product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
5 work-hours x $85 per hour = $425....... $8,000 $8,425 Up to $15,282,950.
----------------------------------------------------------------------------------------------------------------
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 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) 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

unless already done.
(g) Definitions
(1) For the purposes of this AD, a serviceable PMA Ni-Cd battery
is defined as a PMA battery approved for a Ni-Cd battery identified
in Figure 1 to paragraph (c) of this AD, all serial numbers, which
was, prior to installation, fully (re)charged in an approved battery
shop at constant current and after (re)charging, was never installed
and (re)connected to an airplane which was parked or stored for more
than 2 days, except when the disconnection and subsequent connection
of the battery has been accomplished using the preservation
procedures as defined in the applicable service information
specified in paragraphs (g)(1)(i) through (iii) of this AD. Where
the applicable service information refers to Ni-Cd battery part
numbers, use those procedures, as applicable, for the PMA batteries
that are approved for that part number.

Operators Transmission (AOT) A24N006-20, dated September 9, 2020.
(ii) For A330 and A340 airplanes: Airbus AOT A24L007-20, dated
September 23, 2020.
(iii) For A380 airplanes: Airbus AOT A24R009-20, dated September
23, 2020.
(2) For the purposes of this AD, a serviceable non-PMA Ni-Cd
battery is defined as a type design Ni-Cd battery having a part
number identified in Figure 1 to paragraph (c) of this AD, all
serial numbers, which was, prior to installation, fully (re)charged
in an approved battery shop at constant current and after
(re)charging, was never installed and (re)connected to an airplane
which was parked or stored for more than 2 days, except when the
disconnection and subsequent connection of the battery has been
accomplished using the preservation procedures as defined in the
applicable service information specified in paragraphs (g)(1)(i)
through (iii) of this AD.
(3) For the purposes of this AD, a reconnection cycle is defined
as one instance of disconnection and connection of a battery,
installed on an airplane, to the airplane electrical system during
parking or storage periods (for A330 and A340 airplanes) or parking
periods (for A318, A319, A320, A321 and A380 airplanes) since the
last battery charge at constant current in an approved battery shop,
as defined in the applicable service information specified in
paragraphs (g)(1)(i) through (iii) of this AD, except when the
conditions specified in paragraph (g)(3)(i) or (ii) have been met.
Where the applicable service information refers to Ni-Cd battery
part numbers, use those procedures, as applicable, for the PMA
batteries that are approved for that part number.
(i) The on-wing battery preservation procedures as defined in
the applicable service information specified in paragraphs (g)(1)(i)
through (iii) of this AD have been applied.
(ii) The battery has been disconnected, physically removed from
the airplane and then subsequently installed and connected following
a shop visit as defined in the applicable service information
specified in paragraphs (g)(1)(i) through (iii) of this AD.
(4) For the purposes of this AD: Group 1 airplanes are those
which have a PMA part approved for Ni-Cd batteries identified in
Figure 1 to paragraph (c) of this AD installed, which has more than
4 reconnection cycles. Group 2 airplanes are those which have a PMA
part approved for Ni-Cd batteries identified in Figure 1 to
paragraph (c) of this AD installed, which has 4 or less reconnection
cycles, or have a serviceable PMA Ni-Cd battery.
(h) Replacement
(1) For Group 1 airplanes: Within the applicable compliance time
specified in paragraphs (h)(1)(i) and (ii) of this AD and thereafter
before each release to service of an airplane after parking or
storage, as applicable, replace each PMA part approved for a Ni-Cd
battery identified in Figure 1 to paragraph (c) of this AD with a
serviceable PMA Ni-Cd battery or serviceable non-PMA Ni-Cd battery,
in accordance with the instructions of the applicable service
information specified in paragraphs (g)(1)(i) through (iii) of this
AD. Where the applicable service information refers to Ni-Cd battery
part numbers, use those procedures, as applicable, for the PMA
batteries that are approved for that part number. After replacement
of a battery with a serviceable PMA Ni-Cd battery, the airplane
becomes a Group 2 airplane.
Note 1 to paragraph (h)(1): For airplanes on which a battery is
replaced with a serviceable non-PMA Ni-Cd battery, the airplane is
no longer affected by this AD. Refer to Docket Number FAA-2021-0350
(86 FR 25810; May 11, 2021) [as a notice of proposed rulemaking] for
requirements for serviceable non-PMA Ni-Cd batteries.
Note 2 to paragraph (h)(1): For Group 1 and Group 2 airplanes,
guidance on preventing further reduction of the capacity of Ni-Cd
batteries can be found in the off-wing or on-wing battery
preservation procedures (including battery shop visits, as
applicable) detailed in the applicable service information specified
in paragraphs (g)(1)(i) through (iii) of this AD.
(i) For A318, A319, A320 and A321 airplanes: Within 4 months
after the effective date of this AD.
(ii) For A330, A340, and A380 airplanes: Within 6 months after
the effective date of this AD.
(2) For Group 2 airplanes: A Group 2 airplane on which the
preservation procedures, as detailed in the applicable
[[Page 37939]]
service information specified in paragraphs (g)(1)(i) through (iii)
of this AD, are not accomplished becomes a Group 1 airplane after
application of more than 4 reconnection cycles and must comply with
paragraph (h)(1) of this AD. A Group 2 airplane on which
preservation procedures, as detailed in the applicable service
information specified in paragraphs (g)(1)(i) through (iii) of this
AD, continue to be accomplished, remains a Group 2 airplane. Where
the applicable service information refers to Ni-Cd battery part
numbers, those procedures, as applicable, must be used for the PMA
batteries that are approved for that part number.
(i) Preservation
For Group 2 airplanes: As of the effective date of this AD,
provided that the preservation procedures (off-wing or on-wing, as
applicable) are accomplished on an airplane in accordance with the
instructions of the applicable service information specified in
paragraphs (g)(1)(i) through (iii) of this AD, no replacements of
affected parts in accordance with the requirements of paragraph
(h)(1) of this AD are required (anymore) for that airplane. Where
the applicable service information refers to Ni-Cd battery part
numbers, those procedures, as applicable, must be used for the PMA
batteries that are approved for that part number.
(j) No Reporting Requirement
Although the service information specified in paragraphs
(g)(1)(i) through (iii) of this AD specifies to submit certain
information to the manufacturer, this AD does not include that
requirement.
(k) Other FAA AD Provisions
The following provisions also apply to this AD:
