AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2019–22– 

02, which applied to all The Boeing 

Company Model 747–200B, 747–200C, 

747–200F, 747–300, 747–400, 747– 

400D, 747–400F, 747–8F, and 747–8 

series airplanes. AD 2019–22–02 

required identifying the part number, 

and the serial number if applicable, of 

the Captain’s and First Officer’s seats, 

and applicable on-condition actions for 

affected seats. AD 2019–22–02 also 

required a one-time detailed inspection 

and repetitive checks of the horizontal 

movement system (HMS) of the 

Captain’s and First Officer’s seats, and 

applicable on-condition actions. This 

AD was prompted by reports of 

uncommanded fore and aft movement of 

the Captain’s and First Officer’s seats. 

This AD requires the actions in AD 

2019–22–02 and adds an inspection of 

previously omitted part numbers. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective March 19,

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2019–22–02, 

Amendment 39–19781 (84 FR 67854, 

December 12, 2019) (AD 2019–22–02). 

AD 2019–22–02 applied to all The 

Boeing Company Model 747–200B, 747– 

200C, 747–200F, 747–300, 747–400, 

747–400D, 747–400F, 747–8F, and 747– 

8 series airplanes. The NPRM published 

in the Federal Register on September 9, 

2024 (89 FR 73014). The NPRM was 

prompted by reports of uncommanded 

fore and aft movement of the Captain’s 

and First Officer’s seats. In the NPRM, 

the FAA proposed to continue to require 

the actions in AD 2019–22–02 and add 

an inspection of previously omitted part 

numbers. The FAA is issuing this AD to 

address uncommanded fore and aft 

movement of the Captain’s and First 

Officer’s seats. An uncommanded fore 

or aft seat movement during a critical 

part of a flight, such as takeoff or 

landing, could cause a flight control 

obstruction or unintended flight control 

input, which could result in the loss of 

the ability to control the airplane. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

the Air Line Pilots Association, 

International, who supported the NPRM 

without change. 

The FAA received additional 

comments from United Parcel Service 

Co. (UPS). The following presents the 

comments received on the NPRM and 

the FAA’s response to each comment. 

Request To Correct Service Date 

United requested that the date on 

Boeing Special Attention Service 

Bulletin 747–25–3653, Revision 1, be 

corrected to read October 19, 2018. UPS 

commented that table 1 to paragraph (j) 

in the proposed AD lists Boeing Special 

Attention Service Bulletin 747–25– 

3653, Revision 1, with the incorrect date 

of October 18, 2018. 

The FAA agrees that Boeing Service 

Bulletin 747–25–3653, Revision 1, 

called out three times in table 1 to 

paragraph (j) of this AD, should have the 

revision date of October 19, 2018, not 

October 18, 2018. The correct date has 

been reflected in this AD. 

Request To Add Missing Ipeco Service 

Bulletin Issue to Table 1 

UPS requested that all references in 

table 1 to paragraph (j) in the proposed 

AD related to IPECO SB 258–25–08 

should say ‘‘IPECO SB 258–25–08, Issue 

4 or later.’’ UPS noted that in table 1 to 

paragraph (j) in the proposed AD for 

IPECO P/N 3A258–0041–01–1 or 

3A258–0042–01–1, only Issues 5 and 6 

of IPECO SB 258–25–08 are identified 

for installation. Boeing Service Bulletin 

747–25–3644, Revision 1, dated July 17, 

2018, also listed the accomplishment of 

IPECO SB 258–25–08, Issue 4, along 

with Issues 5 and 6. Issues 4, 5, and 6 

of this service bulletin all list the same 

work steps for accomplishment for the 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 90, No. 28 / Wednesday, February 12, 2025 / Rules and Regulations 9383 

IPECO P/N 3A258–0041–01–1 or 

3A258–0042–01–1 seats. 

The FAA agrees with the request and 

has included in this AD Ipeco SB 258– 

25–08, Issue 4, dated April 25, 2014, in 

Table 1 to paragraph (j) of this AD for 

Ipeco P/N 3A258–0041–01–1 or 3A258– 

0042–01–1. 

Request To Clarify Intent of Service 

Bulletin 747–25–3644 

UPS stated that paragraph (j) lacks 

details to ensure the operators 

understand the intent of table 1 to 

paragraph (j) in the proposed AD for 

Service Bulletin 747–25–3644. UPS 

therefore requested that table 1 to 

paragraph (j) in the proposed AD state 

that no further actions are required if 

the operator has completed either action 

in the applicable IPECO service bulletin 

or the performed manual override cable 

maintenance in accordance with the 

component maintenance manual. 

The FAA disagrees to revise 

paragraph (j) of this AD. Boeing SB 747– 

25–3644 Revision 1, dated July 17, 2018, 

states that if the applicable Ipeco P/N 

has a serial number identified by the 

effectivity of the applicable Ipeco 

service bulletin and the manual override 

cable maintenance has been completed 

on the seat in accordance with the Ipeco 

CMM listed in the table, no further 

action is required for this seat. The 

Ipeco service bulletin also state whether 

the Ipeco service bulletin does not apply 

to those seats where maintenance logs 

show that the cables have been 

inspected, replaced, or adjusted per the 

applicable CMM. The FAA has not 

changed this AD as a result of this 

comment. 

Request To Change the Wording in 

Column Headers 

UPS requested that the wording 

‘‘Installation per Boeing Special 

Attention SB’’ and ‘‘Installation per 

IPECO SB’’ for column headers should 

be titled ‘‘Work Accomplished in 

accordance with . . . .’’ UPS stated 

these documents are provided for 

guidance to the operators on how to 

comply with a safety issue. 

The FAA agrees to change the 

headings for the first two columns of 

table 1 to paragraph (j) of this AD to 

‘‘Actions done in accordance with 

Boeing Special Attention Service 

Bulletin’’ and ‘‘Actions done in 

accordance with Ipeco Service 

Bulletin.’’ 

Conclusion 

The FAA reviewed the relevant data, 

considered any 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 these 

products. Except for minor editorial 

changes, and any other changes 

described previously, 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 

The FAA reviewed Boeing Special 

Attention Service Bulletin 747–25– 

3644, Revision 2, dated January 27, 

2023. This material specifies procedures 

for identification of the part number, 

and the serial number if applicable, of 

the Captain’s and First Officer’s seats, 

and applicable on-condition actions. 

On-condition actions include an 

inspection of each seat’s fore and aft and 

vertical manual control levers for 

looseness, installation of serviceable 

seats, and a seat operational test after 

any cable adjustment. This material also 

adds Ipeco seat part numbers 3A258– 

0041–01–1Z and 3A258–0042–01–1Z. 

The FAA also reviewed Boeing 

Special Attention Service Bulletin 747– 

25–3653, Revision 2, dated January 27, 

2023. This material describes 

procedures for a detailed inspection and 

repetitive checks of the HMS (including 

for any Artus part and amendment 

numbers of the horizontal actuator of 

the HMS) for the Captain’s and First 

Officer’s seats for findings (e.g., 

evidence of cracks, scores, corrosion, 

dents, deformation, or visible wear; and 

incorrectly assembled microswitch 

assemblies, actuators, and limit 

switches), and applicable on-condition 

actions. The on-condition actions 

include clearing the seat tracks of 

foreign object debris (FOD), overhauling 

the HMS, and replacing the horizontal 

actuator. This material also describes 

procedures for an optional terminating 

action for the repetitive checks by 

installing a serviceable Captain’s or First 

Officer’s seat. 

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 162 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS PER SEAT

checks specified in this AD. 

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.

Modification of Class D and Class E 

Airspace; Abbotsford Airport, 

Abbotsford, BC 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; correction. 

SUMMARY: The FAA is correcting a final 

rule that published in the Federal 

Register on December 11, 2024. The 

final rule modified administrative 

portions of the Class D and Class E 

airspace legal descriptions for 

Abbotsford Airport, Abbotsford, BC. 

This action corrects errors in the Class 

D airspace legal description. 

DATES: Effective date 0901 UTC, 

February 20, 2025. The Director of the 

Federal Register approves this 

incorporation by reference action under 

1 CFR part 51, subject to the annual

SUPPLEMENTARY INFORMATION: 

History 

The FAA published a final rule in the 

Federal Register (89 FR 99700; 

December 11, 2024) for Docket FAA– 

2024–2440, which modified Class D and 

Class E airspace at Abbotsford Airport, 

Abbotsford, BC. Subsequent to 

publication, the FAA identified that line 

four of the Class D airspace legal 

description contained the incorrect 

geographic location for the Vancouver 

very high frequency omnidirectional 

range/tactical air navigation (VORTAC). 

This action corrects the error by 

removing the reference to the Vancouver 

VORTAC and replacing it with ‘‘Point in 

Space B’’ for description purposes. 

Correction to the Final Rule 

In FR Doc 2024–29085 at 99702, 

published in the Federal Register on 

December 11, 2024, the FAA makes the 

following corrections: 

■ 1. On page 99702, in the first column, 

correct the Class D airspace legal 

description to read as follows: 

ANM WA D Lynden, WA [Corrected] 

Abbotsford Airport, BC 

(Lat. 49°01′31′′ N, long. 122°21′36′′ W) 

Point in Space A 

(Lat. 49°01′31′′ N, long. 122°21′48′′ W) 

Point in Space B

Vancouver International Airport, BC 

(Lat. 49°11′41′′ N, long. 123°11′02′′ W) 

That airspace extending upward from the 

surface to 2,500 feet MSL beginning at lat. 

48°57′59′′ N, long. 122°18′57′′ W, thence 

counterclockwise along the 4-mile radius of 

Point in Space A to lat. 49°00′05′′ N, long. 

122°16′08′′ W, thence west along the U.S./ 

Canadian border to lat. 49°00′05′′ N, long. 

122°45′58′′ W, thence clockwise along the 16- 

mile arc of Point in Space B to lat. 48°57′59′′ 

N, long. 122°47′12′′ W, thence east along lat. 

48°57′59′′ N to the point of beginning, 

excluding the airspace below 1,500 feet MSL 

and west of long. 122°33′50′′ W, the airspace 

within the Vancouver International Airport 

Class C airspace area, and the airspace 

overlying the territory of Canada.
