Federal Register / Vol. 90, No. 28 / Wednesday, February 12, 2025 / Rules and Regulations 9379 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

ATR—GIE Avions de Transport 

Re ́gional Model ATR42 and ATR72 

airplanes. This AD was prompted by a 

report that a flight deck emergency 


lotter on DSK11XQN23PROD with RULES1
9380 Federal Register / Vol. 90, No. 28 / Wednesday, February 12, 2025 / Rules and Regulations 

escape hatch was difficult to open due 

to the hose ends being connected to the 

hatch with incorrect parts and/or 

installed collars with a too-small 

diameter that would not permit the 

drain hose to slide inside. This AD 

requires inspection of the flight deck 

emergency escape hatch drain hose for 

discrepancies and applicable corrective 

actions, and prohibits accomplishment 

of maintenance actions using the 

instructions of certain maintenance 

tasks, 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 March 19, 

2025. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 19, 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 ATR—GIE Avions de 

Transport Re ́gional Model ATR42 and 

ATR72 airplanes. The NPRM published 

in the Federal Register on November 1, 

2024 (89 FR 87314). The NPRM was 

prompted by AD 2024–0090, dated 

April 16, 2024, issued by EASA, which 

is the Technical Agent for the Member 

States of the European Union (EASA AD 

2024–0090) (also referred to as the 

MCAI). The MCAI states that following 

a report that a flight deck emergency 

escape hatch was difficult to open, an 

ATR investigation revealed hatch drain 

hose ends connected to the hatch with 

incorrect parts (zip-tie and ty-rap) and 

installed collars with a too-small 

diameter that would not permit the 

drain hose to slide inside. These 

installation nonconformities could 

occur only during maintenance and 

could affect the hatch drainage and 

possibly result in difficulties in 

removing the hatch in case of an 

emergency evacuation. ATR has 

updated the maintenance procedures to 

clarify the correct procedures. 

In the NPRM, the FAA proposed to 

require inspection of the flight deck 

emergency escape hatch drain hose for 

discrepancies and applicable corrective 

actions, and prohibit accomplishment of 

maintenance actions using the 

instructions of certain maintenance 

tasks, as specified in EASA AD 2024– 

0090. The FAA is issuing this AD to 

address these installation 

nonconformities, which could prevent 

flightcrew evacuation from the airplane 

in case of an emergency, possibly 

resulting in personal injury. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–2418. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from Air 

Line Pilots Association, International 

(ALPA) who supported the NPRM 

without change. 

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 comment 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 

EASA AD 2024–0090 specifies 

procedures for inspecting for 

discrepancies of the flight deck 

emergency escape hatch drain hose 

(including checking for the presence of 

a fastening system on the drain hoses at 

the level of the escape hatch drains and 

checking whether a drain hose slides 

freely in the clamp (collar)). 

Discrepancies include any zip-tie/ty-rap 

that is detected and any drain hose that 

does not slide freely in the clamp. 

Corrective actions include removing the 

fastening system and replacing the 

clamp. EASA AD 2024–0090 also 

prohibits accomplishment of 

maintenance actions using the 

instructions of Maintenance Procedure 

(MP) Tasks ATR–A–52–22–XX–00ZZZ– 

520Z–A and ATR–A–52–22–XX– 

00ZZZ–720Z–A issued December 31, 

2023, or earlier. 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 80 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 

0.25 work-hour × $85 per hour = $21.25 .................................................... $0 $21.25 $1,700 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 90, No. 28 / Wednesday, February 12, 2025 / Rules and Regulations 9381 

The FAA estimates the following 

costs to do any replacement 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 replacement: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per product 

0.25 work-hour × $85 per hour = $21.25 ................................................................................ Minimal ........................... $21.25 

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.

discrepancy, as defined in the AOM, is 

detected’’ for this AD replace that text with 

‘‘any fastening system (e.g., zip-tie/ty-rap) is 

detected or any drain hose does not slide 

freely in the clamp (collar).’’ 

(i) No Reporting 

Although the material referenced in EASA 

AD 2024–0090 specifies to submit certain 

information to the manufacturer, this AD 

does not include that requirement.

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
