Airworthiness Directives; Airbus SAS 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2021–21–02, which applies 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. AD 

2021–21–02 requires replacing certain 

parts manufacturer approval (PMA) NiCd batteries with serviceable Ni-Cd 

batteries or maintaining the electrical 

storage capacity of those PMA Ni-Cd 

batteries during airplane storage or 

parking. Since the FAA issued AD 

2021–21–02, it was determined that the 

on-wing preservation procedures 

originally provided in that AD did not 

ensure the expected preservation of the 

battery capacity. This proposed AD 

would add airplanes to the applicability 

and would require replacing each 

affected part with a serviceable part 

before release to service of an airplane 

after a storage or parking period, as 

applicable. 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 March 25, 2024. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Background 

The FAA issued AD 2021–21–02, 

Amendment 39–21762 (86 FR 62898, 

November 15, 2021) (AD 2021–21–02), 

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. AD 2021–21–02 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. AD 2021–21– 

02 requires replacing certain PMA NiCd batteries with serviceable Ni-Cd 

batteries or maintaining the electrical 

storage capacity of those PMA Ni-Cd 

batteries during airplane storage or 

parking. The agency issued AD 2021– 

21–02 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. 

The FAA issued AD 2021–21–02 to 

address PMA Ni-Cd batteries that are 

similar in design to the type design NiCd batteries identified in FAA AD 

2021–20–08, Amendment 39–21746 (86 

FR 57025, October 14, 2021) (AD 2021– 

20–08), which corresponds to European 

Union Aviation Safety Agency (EASA)

Actions Since AD 2021–21–02 Was 

Issued 

Since the FAA issued AD 2021–21– 

02, EASA superseded EASA AD 2020– 

0274, and issued EASA AD 2023–0196, 

dated November 10, 2023 (EASA AD 

2023–0196), to correct an unsafe 

condition for all: 

• Airbus SAS Model A300 B4–2C,

–642, and –643 airplanes; 

• Airbus SAS Model A350–941 and 

A350–1041 airplanes; and 

• Airbus SAS Model A380–841, –842, 

and –861 airplanes. 

EASA AD 2023–0196 stated that 

Airbus and the Ni-Cd battery 

manufacturer determined that the onwing preservation procedures originally 

provided in the service information 

identified in that AD did not ensure the 

expected preservation of the battery 

capacity. 

The FAA is considering rulemaking to 

supersede FAA AD 2021–20–08 that 

corresponds to EASA AD 2023–0196 to 

address the type design Ni-Cd batteries 

identified in that EASA AD. The FAA 

has determined that any PMA part 

approved for the type design Ni-Cd 

batteries identified in EASA AD 2023– 

0196 are also affected by the unsafe 

condition; therefore, this proposed AD 

would apply to those PMA Ni-Cd 

batteries. 

FAA’s Determination 

The FAA is issuing this NPRM after 

determining that 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 retain none 

of the requirements of AD 2021–21–02. 

This proposed AD would require 

replacing each affected part with a 

serviceable part before release to service 

of an airplane after a storage or parking 

period, as applicable. This proposed AD 

also adds Model A300 series airplanes; 

Model A300 B4–600, B4–600R, and F4– 

600R series airplanes, and Model A300 

C4–605R Variant F airplanes 

(collectively called Model A300–600 

series airplanes); Model A310 series 

airplanes; and Model A350–941 and 

–1041 airplanes to the applicability. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 1,814 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

New proposed actions ..................... 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 

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 has 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 that the 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.

America Code 24, Electrical Power. 

(e) Unsafe Condition 

This 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 unsafe 

condition, if not addressed, 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) Definitions 

(1) For the purposes of this AD, an 

‘‘affected PMA Ni-Cd battery’’ is defined as 

any PMA Ni-Cd battery approved for a Ni-Cd 

battery identified in Figure 1 to the 

introductory text of paragraph (c) of this AD, 

all serial numbers, except those which are a 

serviceable PMA Ni-Cd battery as defined in 

paragraph (g)(2) of this AD. 

(2) For the purposes of this AD, a 

‘‘serviceable PMA Ni-Cd battery’’ is defined 

as a PMA Ni-Cd battery approved for a NiCd battery identified in Figure 1 to the 

introductory text of paragraph (c) of this AD, 

all serial numbers, which was fully 

(re)charged at constant current and, after 

(re)charging, was not stored on wing during 

a period exceeding the applicable ‘‘Time 

Limit’’ specified in Figure 1 to the 

introductory text of paragraph (c) of this AD. 

Periodical, regular, and overhaul checks of a 

PMA Ni-Cd battery that include the battery 

(re)charge at constant current are acceptable 

methods to demonstrate that the battery was 

(re)charged. 

(3) 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 the 

introductory text of paragraph (c) of this AD, 

all serial numbers, which was fully 

(re)charged at constant current and, after 

(re)charging, was not stored on wing during 

a period exceeding the applicable ‘‘Time 

Limit’’ specified in Figure 1 to the 

introductory text of paragraph (c) of this AD. 

Periodical, regular, and overhaul checks of a 

non-PMA Ni-Cd battery that include the 

battery (re)charge at constant current are 

acceptable methods to demonstrate that the 

battery was (re)charged. 

(h) Replacement 

Before release to service of an airplane after 

a storage or parking period, as applicable, 

replace each affected PMA Ni-Cd battery 

with a serviceable PMA Ni-Cd battery or a 

serviceable non-PMA Ni-Cd battery.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to remove 

Airworthiness Directive (AD) 2023–13– 

07, which applies to certain Saab AB, 

Support and Services Model SAAB 

340B airplanes. AD 2023–13–07 

requires amending the applicable 

airplane flight manual (AFM) by 

incorporating a temporary revision (TR) 

to reduce the maximum take-off weight 

(MTOW). AD 2023–13–07 is no longer 

necessary, because of a determination 

that affected airplanes can be safely 

operated up to the initially published 

MTOW. Accordingly, the FAA proposes 

to remove AD 2023–13–07. 

DATES: The FAA must receive comments 

on this proposed AD by March 25, 2024. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

Confidential Business Information 

CBI is commercial or financial

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 Shahram

Background 

The FAA issued AD 2023–13–07, 

Amendment 39–22492 (88 FR 43052, 

July 6, 2023) (AD 2023–13–07), for 

certain Saab AB, Support and Services 

Model SAAB 340B airplanes. AD 2023– 

13–07 was prompted by an MCAI 

originated by the European Union 

Aviation Safety Agency (EASA), which 

is the Technical Agent for the Member 

States of the European Union. EASA 

issued AD 2023–0121, dated June 13, 

2023 (EASA AD 2023–0121) (also 

referred to as the MCAI), to identify and 

correct an unsafe condition. 

AD 2023–13–07 requires amending 

the applicable AFM by incorporating a 

TR to reduce the MTOW. AD 2023–13– 

07 was prompted by a determination 

that the affected airplanes must not be 

operated at a MTOW above 29,000 

pounds. The FAA issued AD 2023–13– 

07 to address the possibility of flight in 

an uncertified envelope, which could 

result in reduced structural capability 

and reduced controllability of the 

airplane. 

Actions Since AD 2023–13–07 Was 

Issued 

Since the FAA issued AD 2023–13– 

07, EASA issued AD Cancellation 

Notice 2023–0121–CN, dated December 

8, 2023 (EASA AD Cancellation Notice 

2023–0121–CN), to cancel EASA AD 

2023–0121. EASA AD Cancellation 

Notice 2023–0121–CN states that since 

EASA AD 2023–0121 was issued, Saab 

provided evidence demonstrating that 

affected airplanes can be operated safely
