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) 

2022–07–15, which applies to all Airbus 

SAS Model A318, A319, A320, and 

A321 series airplanes. AD 2022–07–15 

requires replacing affected braking and 

steering control units (BSCUs) and 

revising the operator’s existing FAAapproved minimum equipment list 

(MEL). Since the FAA issued AD 2022– 

07–15, a type 1 relay combined with an 

affected BSCU would induce BSCU 

freezing. This proposed AD would 

remove certain airplanes from the 

applicability, retain the requirements of 

AD 2022–07–15, require an inspection 

for the relay type installed and 

replacement of type 1 relays with type 

2 relays, and prohibit the installation of 

affected relays at certain locations, limit 

the installation of affected BSCUs on 

certain airplanes, and prohibit the 

installation of affected BSCUs for 

certain other airplanes, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is proposed for 

incorporation by reference (IBR). 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 13, 

2023.

Background 

The FAA issued AD 2022–07–15, 

Amendment 39–22003 (87 FR 22438, 

April 15, 2022), for all Airbus SAS 

Model A318–111, –112, –121, and –122 

airplanes; Model A319–111, –112, –113, 

–114, –115, –131, –132, –133, –151N, 

–153N, and –171N airplanes; Model 

A320–211, –212, –214, –216, –231, 

–232, –233, –251N, –252N, –253N, 

–271N, –272N, –273N airplanes; and 

Model A321–111, –112, –131, –211, 

–212, –213, –231, –232, –251N, –251NX, 

–252N, –252NX, –253N, –253NX, 

–271N, –271NX, –272N, and –272NX 

airplanes. AD 2022–07–15 was 

prompted by an MCAI originated by 

EASA, which is the Technical Agent for 

the Member States of the European 

Union. EASA issued AD 2022–0032, 

dated March 3, 2022 (EASA AD 2022– 

0032), to correct an unsafe condition. 

AD 2022–07–15 requires replacing 

affected BSCUs and revising the 

operator’s existing FAA-approved MEL. 

The FAA issued AD 2022–07–15 to 

address loss of braking performance 

with significant increase in airplane 

stopping distance, possibly resulting in 

runway excursion. 

Actions Since AD 2022–07–15 Was 

Issued 

Since the FAA issued AD 2022–07– 

15, EASA superseded AD 2022–0032 

and issued EASA AD 2023–0093, dated 

May 5, 2023, which was subsequently 


ddrumheller on DSK120RN23PROD with PROPOSALS1
66308 Federal Register / Vol. 88, No. 186 / Wednesday, September 27, 2023 / Proposed Rules 

revised. EASA AD 2023–0093R1, dated 

May 15, 2023 (EASA AD 2022–0093R1) 

(also referred to as the MCAI), retains 

the requirements of EASA AD 2023– 

0032 and requires replacement of type 

1 relays with type 2 relays. 

The MCAI noted that BSCU channel 

failures could induce, in the event of 

dual channel failures, loss of anti-skid 

function together with the reversion to 

the alternate braking mode, and loss of 

nose wheel steering, and lead to loss of 

braking performance with significant 

increase in airplane stopping distance, 

possibly resulting in runway excursion. 

The MCAI states that further 

investigation identified a type 1 relay 

installed in a position where a type 2 

relay should have been installed. The 

combination of a type 1 relay with an 

affected BSCU could induce BSCU 

freezing. EASA therefore determined 

that it is necessary to replace type 1 

relays with type 2 relays. 

The MCAI also states that type 1 

relays are no longer installed on Model 

A320 Current Engine Option (CEO) 

airplanes (i.e., Model A318 series 

airplanes; A319–111, –112, –113, –114, 

–115, –131, –132, and –133 airplanes; 

A320–211, –212, –214, –216, –231, 

–232, and –233 airplanes; and A321– 

111, –112, –131, –211, –212, –213, –231, 

and –232 airplanes). Type 1 relays were 

required to be replaced on Model A320 

CEO airplanes by AD 96–04–06, 

Amendment 39–9518 (61 FR 6927, 

February 23, 1996). AD 96–04–06 

corresponded to DGAC France AD F– 

1993–163–043, dated September 29, 

1993. Model A320 CEO airplanes are 

therefore not included in the 

applicability of this proposed AD. 

Further, EASA stated that some relays 

installed at functional item number 

(FIN) locations 24GG and 25GG were 

not in conformity with the Airplane 

Inspection Report on certain airplanes. 

In addition, it was determined that 

certain airplanes have been delivered 

with a BSCU P/N E21327107. 

Explanation of Retained Requirements 

Although this proposed AD does not 

explicitly restate the requirements of AD 

2022–07–15, this proposed AD would 

retain all the requirements of AD 2022– 

07–15. Those requirements are 

referenced in EASA AD 2023–0093R1, 

which, in turn, is referenced in 

paragraph (g) of this proposed AD. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2023–0093R1 specifies 

procedures for replacing affected BSCUs 

if a fault signature is triggered, and 

implementing the instructions of master 

minimum equipment list (MMEL) 

updates on the basis of which the 

operator’s existing MEL must be 

amended–that is, procedures for 

revising the operator’s existing FAAapproved MEL with the provisions in 

the MMEL updates specified in the 

EASA AD. EASA AD 2023–0093R1 also 

specifies procedures for a general visual 

inspection of the FINs 24GG and 25GG 

to identify the relay type installed, and 

replacement of each type 1 relay with a 

type 2 relay. EASA AD 2023–0093R1 

also limits the installation of affected 

parts. 

Airbus Alert Operators Transmission 

A32N025–22, Rev 01, dated May 10, 

2023, including Appendixes 1 through 

3, dated May 2023, defines BSCU fault 

signatures that may be triggered on the 

airplane, and specifies procedures for 

replacing affected parts, among other 

actions. 

This proposed AD would also require 

Airbus Alert Operators Transmission 

A32N025–22, Rev 00, dated February 

24, 2022, including Appendixes 1 

through 4, dated February 21, 2022, 

which the Director of the Federal 

Register approved for incorporation by 

reference as of May 2, 2022 (87 FR 

22438, April 15, 2022). 

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 

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 this State of 

Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI referenced above. The FAA 

is issuing this NPRM after determining 

that the unsafe condition described 

previously is likely to exist or develop 

in other products of the same type 

design. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would retain all 

requirements of AD 2022–07–15. This 

proposed AD would remove airplanes 

from the applicability and require 

accomplishing the actions specified in 

EASA AD 2023–0093R1 described 

previously, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Compliance With MEL Revisions 

EASA AD 2023–0093R1 requires 

operators to ‘‘inform all flight crews’’ of 

revisions to the MEL, and thereafter to 

‘‘operate the airplane accordingly.’’ 

However, this proposed AD would not 

specifically require those actions as 

those actions are already required by 

FAA regulations. FAA regulations (14 

CFR 121.628 (a)(2)) require operators to 

provide pilots with access to all of the 

information contained in the operator’s 

MEL. Furthermore, 14 CFR 121.628 

(a)(5) requires airplanes to be operated 

under all applicable conditions and 

limitations contained in the operator’s 

MEL. Therefore, including a 

requirement in this proposed AD to 

operate the airplane according to the 

revised MEL would be redundant and 

unnecessary. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, the FAA proposes to 

incorporate EASA AD 2023–0093R1 by 

reference in this AD. This proposed AD 

would, therefore, require compliance 

with EASA AD 2023–0093R1 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 EASA AD 2023–0093R1 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 EASA AD 2023–0093R1. 

Service information required by EASA 

AD 2023–0093R1 for compliance will be 

available at regulations.gov under 

Docket No. FAA–2023–1882 after the 

FAA final rule is published. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 349 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 


ddrumheller on DSK120RN23PROD with PROPOSALS1
Federal Register / Vol. 88, No. 186 / Wednesday, September 27, 2023 / Proposed Rules 66309 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Retained actions from AD 2022–07– 

15.

Up to 5 work-hours × $85 per hour 

= $425.

$0 Up to $425 ................... Up to $148,325. 

Relay inspection and replacement 

(new proposed actions).

Up to 9 work-hours × $85 per hour 

= $765.

0 Up to 765 ..................... Up to 266,985. 

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 the 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) 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

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by: 

■ a. Removing Airworthiness Directive 

(AD) 2022–07–15, Amendment 39– 

22003 (87 FR 22438, April 15, 2022); 

and 

■ b. Adding the following new AD: 

Airbus SAS: Docket No. FAA–2023–1882; 

Project Identifier MCAI–2023–00651–T. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by November 

13, 2023. 

(b) Affected ADs 

This AD replaces AD 2022–07–15, 

Amendment 39–22003 (87 FR 22438, April 

15, 2022) (AD 2022–07–15). 

(c) Applicability 

This AD applies to the Airbus SAS 

airplanes, certificated in any category, 

identified in paragraphs (c)(1) through (3) of 

this AD. 

(1) All Model A319–151N, A319–153N, 

and A319–171N airplanes. 

(2) All Model A320–251N, A320–252N, 

A320–253N, A320–271N, A320–272N, and 

A320–273N airplanes. 

(3) All Model A321–251N, A321–251NX, 

A321–252N, A321–252NX, A321–253N, 

A321–253NX, A321–271N, A321–271NX, 

A321–272N, and A321–272NX airplanes. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 32, Landing Gear; and 

America Code 92, Electrical System 

Installation. 

(e) Unsafe Condition 

This AD was prompted by the detection of 

several channel failures on the braking and 

steering control unit (BSCU), inducing, in 

case of dual channel failures, loss of anti-skid 

function together with the reversion to the 

alternate braking mode, and loss of nose 

wheel steering. This AD was further 

prompted by the determination that a type 1 

relay combined with an affected BSCU could 

induce BSCU freezing. The FAA is issuing 

this AD to address these conditions, which 

could lead to loss of braking performance 

with significant increase in airplane stopping 

distance, possibly resulting in runway 

excursion. 

(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) 2023–0093R1, dated 

May 15, 2023 (EASA AD 2023–0093R1). 

(h) Exceptions to EASA AD 2023–0093R1 

(1) Where EASA AD 2023–0093R1 refers to 

‘‘10 March 2022 [the effective date of EASA 

AD 2022–0032 at original issue],’’ this AD 

requires using May 2, 2022 (the effective date 

of AD 2022–07–15). 

(2) Where EASA AD 2023–0093R1 refers to 

its effective date, this AD requires using the 

effective date of this AD. 

(3) Where EASA AD 2023–0093R1 defines 

‘‘the AOT 1’’ as ‘‘Airbus Alert Operators 

Transmission (AOT 1) A32N025–22,’’ this 

AD requires using Airbus Alert Operators 

Transmission A32N025–22, Rev 00, dated 

February 24, 2022, including Appendixes 1 

through 4, dated February 21, 2022, or Airbus 

Alert Operators Transmission A32N025–22, 

Rev 01, dated May 10, 2023, including 

Appendixes 1 through 3, dated May 2023. 

(4) Where paragraphs (2) and (3) of EASA 

AD 2023–0093R1 specify ‘‘in accordance 

with the instructions of the AOT 1,’’ replace 

those words with ‘‘in accordance with the 

‘Remove and replace BSCU P/N E21327307’ 

step in paragraph 5.6., ‘Instructions,’ of 

Airbus Alert Operators Transmission 

A32N025–22, Rev 00, dated February 24, 

2022, including Appendixes 1 through 4, 

dated February 21, 2022, or of Airbus Alert 

Operators Transmission A32N025–22, Rev 

01, dated May 10, 2023, including 

Appendixes 1 through 3, dated May 2023.’’ 

No other actions in Airbus Alert Operators 

Transmission A32N030–23, Rev 00, dated 

February 27, 2023, including Appendixes 1 

and 2, dated February 21, 2023 (referenced in 

EASA AD 2023–0093R1 and not incorporated 

by reference in this AD), or Airbus Alert 

Operators Transmission A32N025–22, Rev 

01, dated May 10, 2023, including 


ddrumheller on DSK120RN23PROD with PROPOSALS1
66310 Federal Register / Vol. 88, No. 186 / Wednesday, September 27, 2023 / Proposed Rules 

Appendixes 1 through 3, dated May 2023, are 

required for compliance for the replacement. 

(5) Where paragraph (4) of EASA AD 2023– 

0093R1 requires operators to ‘‘implement the 

instructions of the MMEL [master minimum 

equipment list] update,’’ this AD requires 

replacing those words with ‘‘implement the 

operator’s existing FAA-approved minimum 

equipment list (MEL) with the provisions 

specified in ‘The MMEL update’ as identified 

in EASA AD 2023–0093R1.’’ 

(6) Where paragraph (4) of EASA AD 2023– 

0093R1 specifies to ‘‘inform all flight crews, 

and, thereafter, operate the airplane 

accordingly,’’ this AD does not require those 

actions as those actions are already required 

by existing FAA operating regulations. 

(7) This AD does not adopt the ‘‘Remarks’’ 

section of EASA AD 2023–0093R1. 

(i) No Reporting Requirement 

Although certain service information 

specified in EASA AD 2023–0093R1 specifies 

to report certain information and send 

affected parts to the manufacturer, this AD 

does not require those actions. 

(j) Additional AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, 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

corresponding provisions of EASA AD 2023– 

0093R1 that are required by paragraph (g) of 

this AD. 

(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, 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 contains procedures 

or tests that are identified as RC, those

with this AD; any procedures or tests that are 

not identified as RC are recommended. Those 

procedures and tests that are 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 procedures and tests identified as RC can 

be done and the airplane can be put back in 

an airworthy condition. Any substitutions or 

changes to procedures or tests identified as 

RC require approval of an AMOC.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2019–16–05, which applies to all The 

Boeing Company Model 777 airplanes. 

AD 2019–16–05 requires an 

identification of the part number, and if 

applicable the serial number, of the 

Captain’s and First Officer’s seats, and 

applicable on-condition actions for 

affected seats. Since the FAA issued AD 

2019–16–05, the FAA has discovered 

that certain seat part numbers had been 

inadvertently omitted from the 

inspection requirements of AD 2019– 

16–05. This proposed AD would retain 

the requirements of AD 2019–16–05 and 

would add inspection of the previously 

omitted part numbers. 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 13, 

2023. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

regulations.gov. Follow the instructions 

for submitting comments. 

• Fax: 202–493–2251.

Transportation, Docket Operations, M–

W12–140, 1200 New Jersey Avenue SE, 

Washington, DC 20590. 

• Hand Delivery: Deliver to Mail 

address above between 9 a.m. and 5 

p.m., Monday through Friday, except 

Federal holidays. 

AD Docket: You may examine the AD 

docket at regulations.gov under Docket 

No. FAA–2023–1879; or in person at 

Docket Operations between 9 a.m. and 

5 p.m., Monday through Friday, except 

Federal holidays. The AD docket 

contains this NPRM, any comments 

received, and other information. The 

street address for Docket Operations is 

listed above.
