Abstract
The FAA is adopting 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 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 AD requires 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 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 issuing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting 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 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 AD requires 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 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 issuing this AD to
address the unsafe condition on these products.
DATES: This AD is effective December 20, 2021.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of December 20,
2021.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to 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. The NPRM published in the Federal Register on
July 19, 2021 (86 FR 37936). The NPRM was prompted by a determination
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. In the NPRM, the FAA proposed to
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. The NPRM
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
issuing 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.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from Air Line Pilots Association,
International, which supported the NPRM without change.
[[Page 62899]]
The FAA received additional comments from two commenters, including
American Airlines and United Airlines. The following presents the
comments received on the NPRM and the FAA's response to each comment.
Request To Combine Rulemaking
American Airlines and United Airlines stated there is an NPRM,
Docket No. FAA-2021-0350 (86 FR 25810, May 11, 2021), for a different
AD that addresses an unsafe condition for certain type design Ni-Cd
batteries (original equipment manufacturer (OEM) parts) on Airbus
airplanes, which corresponds to European Union Aviation Safety Agency
(EASA) AD 2020-0274, dated December 10, 2020 (EASA AD 2020-0274).
American Airlines and United Airlines noted that this NPRM, Docket No.
FAA-2021-0547, addresses that same unsafe condition for PMA Ni-Cd
batteries (PMA parts) and has the same required actions. American
Airlines requested that the intent of both NPRMs be combined into a
single AD to simplify tracking and actions associated with the
aforementioned NPRMs. United Airlines questioned why the FAA is
planning on issuing two separate ADs.
The FAA does not agree to combine both NPRMs into a single AD. At
the time the NPRMs were developed, the FAA separated the rulemaking for
OEM parts from the PMA parts since the FAA was informed of
implementation issues with the adoption of combined rulemaking (OEM
parts and PMA parts) by the foreign civil aviation authorities.
Therefore, as an interim action, the FAA has decided to issue separate
ADs for the OEM parts and the PMA parts. The FAA is discussing how to
address OEM and PMA parts in ADs for future rulemaking. However, in the
interest of safety to address the unsafe condition on the PMA parts
identified in this AD, the FAA has determined this AD cannot be
delayed.
Request for Information on the Work Scope
United Airlines stated that the requirements in paragraphs (g),
(h), and (i) of the proposed AD for the PMA parts have more detail than
the requirements in NPRM, Docket No. FAA-2021-0350, for the OEM parts.
United Airlines asked if there is contrasting work scopes between the
OEM parts NPRM and the PMA parts NPRM.
The FAA notes that the work scope is the same in both NPRMs. The
OEM parts NPRM (published as AD 2021-20-08, Amendment 39-21746 (86 FR
57025, October 14, 2021)), refers to EASA AD 2020-0274 as the
appropriate source of service information. EASA AD 2020-0274 provides
the details for the required actions. Paragraphs (g), (h), and (i) of
this AD correspond to the Definitions and paragraphs (1) and (2) of
EASA AD 2020-0274.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, and determined that air safety requires adopting this AD as
proposed. Except for minor editorial changes, this AD is adopted as
proposed in the NPRM. None of the changes will increase the economic
burden on any operator.

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.
Costs of Compliance
The FAA estimates that this AD affects up to 1,814 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this 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
This AD will not have federalism implications under Executive Order
13132. This AD will 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 that this AD:
(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.

AOT A24R009-20, Rev 00, 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

serviceable PMA Ni-Cd battery or serviceable non-PMA
[[Page 62901]]
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): Airplanes on which a battery is
replaced with a serviceable non-PMA Ni-Cd battery are no longer
affected by this AD. AD 2021-20-08, Amendment 39-21746 (86 FR 57025,
October 14, 2021), provides 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 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:
