Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2022–10– 

08, which applied to certain Airbus SAS 

Model A320–214, –251N, and –271N 

airplanes. AD 2022–10–08 required a 

one-time detailed inspection of the 

affected passenger seats and corrective 

actions if necessary. Since the FAA 

issued AD 2022–10–08, it was 

determined that additional passenger 

seats are affected. This AD continues to 

require the actions in AD 2022–10–08, 

and also requires inspecting additional 

affected passenger seats; as specified in 

a European Union Aviation Safety 

Agency (EASA) AD, which is 

incorporated by reference. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective September 

13, 2023. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of September 13, 2023.

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this AD 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 AD, 

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

commentary that the FAA receives 

which is not specifically designated as 

CBI will be placed in the public docket 

for this rulemaking. 

Background 

The FAA issued AD 2022–10–08, 

Amendment 39–22046 (87 FR 31129, 

May 23, 2022) (AD 2022–10–08), for 

certain Airbus SAS Model A320–214, 

–251N, and –271N airplanes. AD 2022– 

10–08 was prompted by an MCAI 

originated by EASA, which is the 

Technical Agent for the Member States 

of the European Union. EASA issued 

AD 2021–0166, dated July 13, 2021 

(EASA AD 2021–0166), to correct an 

unsafe condition. 

AD 2022–10–08 required a one-time 

detailed inspection of the affected 

passenger seats and corrective actions if 

necessary. The FAA issued AD 2022– 

10–08 to address deformation or 

compression of the seat rail covers 

caused by improper transportation, 

handling, or installation on the airplane. 

This condition, if not addressed, could 

lead to seat track detachment, possibly 

resulting in injury to passengers. 

Actions Since AD 2022–10–08 Was 

Issued 

Since the FAA issued AD 2022–10– 

08, EASA superseded EASA AD 2021– 

0166, and issued EASA AD 2021– 

0166R1, dated December 22, 2022 

(EASA AD 2021–0166R1) (also referred 

to as the MCAI), to correct an unsafe 

condition for certain Airbus SAS Model 

A320–214, –251N, and –271N airplanes. 

The MCAI states that damaged seat rail 

covers were detected in the forward and 

aft seat fixation area of some airplanes 

during initial delivery. The MCAI states 

that since EASA AD 2021–0166 was 

issued, it was determined that 

additional passenger seats are affected. 

The FAA is issuing this AD to address 

deformation or compression of the seat 

rail covers caused by improper 

transportation, handling, or installation 

on the airplane. This condition, if not 

addressed, could lead to seat track 

detachment, possibly resulting in injury 

to passengers. You may examine the 

MCAI in the AD docket at 

regulations.gov under Docket No. FAA– 

2023–1491. 

Explanation of Retained Requirements 

Although this AD does not explicitly 

restate the requirements of AD 2022– 

10–08, this AD retains all of the 

requirements of AD 2022–10–08. Those 

requirements are referenced in EASA 

AD 2021–0166R1, which, in turn, is 

referenced in paragraph (g) of this AD. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0166R1 specifies 

procedures for a detailed inspection of 

the affected parts and corrective actions. 

Corrective actions include replacement 

of the seat or the seat rail covers. 

This AD also requires EASA AD 

2021–0166, which the Director of the 

Federal Register approved for 

incorporation by reference on June 7, 

2022 (87 FR 31129, May 23, 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 described above. The FAA 

is issuing this AD after determining that 


ddrumheller on DSK120RN23PROD with RULES1
59444 Federal Register / Vol. 88, No. 166 / Tuesday, August 29, 2023 / Rules and Regulations 

the unsafe condition described 

previously is likely to exist or develop 

on other products of the same type 

design. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in EASA AD 2021– 

0166R1 described previously, 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 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, EASA AD 2021– 

0166R1 is incorporated by reference in 

this AD. This AD requires compliance 

with EASA AD 2021–0166R1 in its 

entirety through that incorporation, 

except for any differences identified as 

exceptions in the regulatory text of this 

AD. Using common terms that are the 

same as the heading of a particular 

section in EASA AD 2021–0166R1 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 2021–0166R1. 

Service information required by EASA 

AD 2021–0166R1 for compliance will be 

available at regulations.gov under 

Docket No. FAA–2023–1491 after this 

AD is published. 

FAA’s Justification and Determination 

of the Effective Date 

There are currently no domestic 

operators of these products. 

Accordingly, notice and opportunity for 

prior public comment are unnecessary, 

pursuant to 5 U.S.C. 553(b)(3)(B). In 

addition, for the forgoing reasons, the 

FAA finds that good cause exists 

pursuant to 5 U.S.C. 553(d) for making 

this amendment effective in less than 30 

days. 

Regulatory Flexibility Act (RFA) 

The requirements of the RFA do not 

apply when an agency finds good cause 

pursuant to 5 U.S.C. 553 to adopt a rule 

without prior notice and comment. 

Because the FAA has determined that it 

has good cause to adopt this rule 

without notice and comment, RFA 

analysis is not required. 

Costs of Compliance 

Currently, there are no affected U.S.- 

registered airplanes. If an affected 

airplane is imported and placed on the 

U.S. Register in the future, the FAA 

provides the following cost estimates to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per 

product 

Retained actions from AD 2022–10–08 ....................... 2 work-hours × $85 per hour = $170 ........................... $0 $170 

New actions .................................................................. 2 work-hours × $85 per hour = $170 ........................... 0 170 

The FAA estimates the following 

costs to do any necessary on-condition 

action that would be required based on 

the results of any required actions. The 

FAA has no way of determining the 

number of aircraft that might need this 

on-condition action: 

ESTIMATED COSTS OF ON-CONDITION ACTION

Action Labor cost Parts cost Cost per product 

Seat rail cover replacement ........... 1 work-hour × $85 per hour = $85 ........................................................ Up to $160 ....... Up to $245 (per 

rail cover). 

Seat replacement ........................... 3 work-hours × $85 per hour = $255 .................................................... Up to $21,600 ... Up to $21,855 

(per seat). 

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, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

22505; Docket No. FAA–2023–1491; 

Project Identifier MCAI–2022–01644–T. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective September 13, 2023. 

(b) Affected ADs 

This AD replaces AD 2022–10–08, 

Amendment 39–22046 (87 FR 31129, May 23, 

2022) (AD 2022–10–08). 

(c) Applicability 

This AD applies to Airbus SAS Model 

A320–214, –251N, and –271N airplanes, 

certificated in any category, as identified in 

European Union Aviation Safety Agency 

(EASA) AD 2021–0166R1, dated December 

22, 2022 (EASA AD 2021–0166R1). 

(d) Subject 

Air Transport Association (ATA) of 

America Code 25, Equipment/Furnishings. 

(e) Unsafe Condition 

This AD was prompted by reports that 

damaged seat rail covers were detected in the 

forward and aft seat fixation area of some 

airplanes during initial delivery. Since AD 

2022–10–08 was issued, it was determined 

that additional passenger seats are affected. 

The FAA is issuing this AD to address 

deformation or compression of the seat rail 

covers caused by improper transportation, 

handling, or installation on the airplane. This 

condition, if not addressed, could lead to seat 

track detachment, possibly resulting in injury 

to passengers. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraphs (h) and 

(i) of this AD: Comply with all required 

actions and compliance times specified in, 

and in accordance with, EASA AD 2021– 

0166R1. 

(h) Exceptions to EASA AD 2021–0166R1 

(1) Where paragraph (1) of EASA AD 2021– 

0166R1 specifies to accomplish a detailed 

inspection of each affected part within 12 

months after July 27, 2021 (the effective date 

of EASA AD 2021–0166, dated July 13, 2021 

(EASA AD 2021–0166)), for this AD do the 

inspection at the applicable compliance time 

specified in paragraph (h)(1)(i) or (ii) of this 

AD. 

(i) For the parts identified in Appendix 1 

of EASA AD 2021–0166, do the inspection 

within 12 months after June 7, 2022 (the 

effective date of AD 2022–10–08). 

(ii) For the parts identified in Appendix 1 

of EASA AD 2021–0166R1, except those 

identified in Appendix 1 of EASA AD 2021– 

0166, do the inspection within 6 months after 

the effective date of this AD. 

(2) Where paragraph (2) of EASA AD 2021– 

0166R1 specifies actions if ‘‘discrepancies are 

detected,’’ for this AD a discrepancy is an 

out-of-tolerance distance between the 

forward and aft attachment screws or a 

damaged (deformed or compressed) seat rail 

cover. 

(3) Where paragraph (3) of EASA AD 2021– 

0166R1 allows deferral of certain actions, for 

this AD replace the text ‘‘in accordance with 

the applicable instructions and limitations of 

Master Minimum Equipment List (MMEL) 

item 25–20–01A’’ with ‘‘in accordance with 

the applicable instructions and limitations of 

FAA MMEL item 25–21–01 or equivalent 

instructions and limitations in the operator’s 

existing FAA-approved minimum equipment 

list (MEL)’’. 

(4) Where paragraph (4) of EASA AD 2021– 

0166R1 refers to its effective date, this AD 

requires using the effective date of this AD. 

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

section of EASA AD 2021–0166R1. 

(i) No Reporting Requirement 

Although the service information 

referenced in EASA AD 2021–0166R1 

specifies to submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

(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 

to the International Validation Branch, send 

it to the attention of the person identified in 

paragraph (k) of this AD. Information may be 

emailed to: 9-AVS-AIR-730-AMOC@faa.gov. 

Before using any approved AMOC, notify 

your appropriate principal inspector, or 

lacking a principal inspector, the manager of 

the responsible Flight Standards Office. 

(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 

procedures and tests must be done to comply 

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.
