ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Canada Limited Partnership 

Model BD–500–1A10 and BD–500– 

1A11 airplanes. This AD was prompted 

by multiple occurrences of pilot and copilot seats locking in a fore-aft position 

due to the seat fore-aft adjustment 

mechanism disconnecting, caused by a 

broken cotter pin in the seat base egress 

linkage. This AD requires modifying the 

pilot and co-pilot seats by replacing the 

hardware of the seat base egress linkage, 

as specified in a Transport Canada 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 January 13, 

2025. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of January 13, 2025.

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 Limited 

Partnership Model BD–500–1A10 and 

BD–500–1A11 airplanes. The NPRM 

published in the Federal Register on 

March 21, 2024 (89 FR 20144). The 

NPRM was prompted by AD CF–2023– 

40, dated June 13, 2023, issued by 

Transport Canada, which is the aviation 

authority for Canada (Transport Canada 

AD CF–2023–40) (also referred to as the 

MCAI). The MCAI states that there have 

been in-service occurrences of pilot and 

co-pilot seats becoming locked in a foreaft position due to disconnection of the 

seat fore-aft adjustment mechanism 

caused by a broken cotter pin in the seat 

base egress linkage. 

In the NPRM, the FAA proposed to 

require modifying the pilot and co-pilot 

seats by replacing the hardware of the 

seat base egress, as specified in 

Transport Canada AD CF–2023–40. The 

FAA is issuing this AD to address the 

disconnection of the seat fore-aft 

adjustment mechanism caused by a 

broken cotter pin in the seat base egress 

linkage. The unsafe condition, if not 

addressed, could result in a significant 

increase in crew workload for continued 

safe flight and landing. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–0468. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

two commenters, including Collins 

Aerospace and Delta Airlines (Delta). 

The following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Request for Later-Approved Service 

Information 

Collins Aerospace and Delta 

requested that the FAA edit paragraph 

(h)(3) of the proposed AD so that it 

would allow the use of later service 

information. Paragraph (h)(3) of the 

proposed AD would mandate Goodrich 

Interiors Service Bulletin 1430–25–003, 

Revision C, dated November 22, 2022. 

The FAA disagrees with the request. 

Transport Canada AD CF–2023–40, 

dated June 13, 2023, refers to ‘‘Airbus 

Canada Service Bulletin (SB) BD500– 

251006, Issue 001, dated 05 April 2023, 

or later revisions approved by the Chief, 

Continuing Airworthiness, Transport 

Canada,’’ but does not specifically allow 

later-approved revisions of any service 

information cited in that Airbus Canada 

service bulletin. The FAA has not 

changed this AD as a result of this 

comment. 

Request for Clarification of Paragraph 

(h)(3) of Proposed AD 

Delta requested clarification of the 

wording in (h)(3) of the proposed AD 


ddrumheller on DSK120RN23PROD with RULES1
97498 Federal Register / Vol. 89, No. 236 / Monday, December 9, 2024 / Rules and Regulations 

where it is specified to ‘‘Do Goodrich 

Interiors Service Bulletin 1430–25–003’’ 

and to update paragraph (h)(3) of the 

proposed AD to include either ‘‘refer to’’ 

or ‘‘in accordance with.’’ The 

commenter would like clarification 

whether the verb ‘‘do’’ implies ‘‘refer 

to’’ or ‘‘in accordance with.’’ 

Conditional on the FAA’s concurrence 

with this request, Delta also requested 

an additional similar exception be 

included in paragraph (h) of the 

proposed AD to allow accomplishment 

of the operational test specified in 

Goodrich Interiors Service Bulletin 

1430–25–003 instructions for the 

Function Check under Section 3.F. 

using the A220 AMP Task BD500–A– 

J25–11–00–01AAA–320A–A in lieu of 

CMM 25–11–20. 

The FAA disagrees with changing 

paragraph (h)(3) of this AD to include 

‘‘refer to’’ or ‘‘in accordance with.’’ To 

clarify, this AD and the service 

information use the word ‘‘do’’ to 

communicate what operators need to 

accomplish, and therefore indicates a 

required action. 

Request for Additional Exception 

Delta requested the addition of the 

following paragraph: ‘‘(h)(4) As the 

Goodrich Interiors Service Bulletin 

1430–25–003 have instructions of 

removal and installation of the affected 

seats from the seat tracks, this AD 

allows the seat removal and installation 

procedures using the AMP procedures 

as listed in the procedure of Service 

Bulletin BD500–251006 Issue No. 001, 

dated 05 April 2023, or later revisions 

approved by the Chief, Continuing 

Airworthiness, Transport Canada.’’ 

Airbus SB BD500–251006 Issue 001 

Procedures section and Goodrich 

Interiors SB 1430–25–003 

Accomplishment Instructions section 

both state that the pilot seats need to be 

removed, so the commenter is 

concerned with confusion due to both 

service bulletins giving instructions to 

perform the same tasks. 

The FAA agrees that the repetition of 

steps in the Airbus and Goodrich 

Interiors SB could lead to confusion if 

operators are trying to follow SB steps. 

The AD should clarify what procedures 

the operators should follow because 

operators may not know whether they 

are in compliance with this AD if there 

are steps that cannot be accomplished. 

The FAA has added paragraph (h)(4) to 

this AD to allow the use of only Airbus 

SB BD500–251006, Issue 001, dated 

April 5, 2023, for seat removal and 

installation procedures. 

Conclusion 

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 

reviewed the relevant data, considered 

the comments received, and determined 

that air safety requires adopting this AD 

as proposed. Accordingly, the FAA is 

issuing this AD to address the unsafe 

condition on this product. 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. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

Transport Canada AD CF–2023–40 

specifies procedures for modifying the 

pilot and co-pilot seats by replacing the 

hardware of the seat base egress linkage. 

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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 23 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Up to 2 work-hours × $85 per hour = $170 ............................................................... Up to $200 .......... Up to $370 .......... Up to $8,510. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected operators. 

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.

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2022–24– 

05, which applied to all Airbus SAS 

Model A318, A319, A320, and A321 

series airplanes. AD 2022–24–05 

required repetitive inspections of 

certain galleys for corrosion of trolley 

retainer aluminum blocks and 

delamination of the upper panel of the 

trolley compartment, and applicable 

corrective action. This AD was 

prompted by the list of affected galleys 

being revised, and a new modification 

that was developed to restore the design 

integrity of the affected galleys. This AD 

continues to require the actions in AD 

2022–24–05, provides optional 

terminating action for the repetitive 

inspections, revises the list of affected 

parts, and prohibits the installation of 

affected parts under certain conditions; 

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 January 13, 

2025.
