AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain ATR—GIE Avions de Transport 

Re ́gional Model ATR42–500 and 

ATR72–212A airplanes. This proposed 

AD was prompted by a report of the 

possible use of improper material 

during the manufacturing of vertical 

stabilizer to horizontal stabilizer 

junction fittings. This proposed AD 

would require inspections of affected 

parts, applicable repairs, and eventual 

replacement of certain affected parts, 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 December 16, 

2024.

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2024–0171, 

dated August 27, 2024 (EASA AD 2024– 

0171) (also referred to as the MCAI), to 

correct an unsafe condition for certain 

ATR—GIE Avions de Transport 

Re ́gional Model ATR42–500 and 

ATR72–212A airplanes. The MCAI 

states that a report was received of the 

possible use of improper material 

during the manufacturing of vertical 

stabilizer to horizontal stabilizer 

junction fittings. Subsequent review 

identified the population of affected 

parts and the airplanes equipped with 

those affected parts. Vertical stabilizer 

to horizontal stabilizer junction fittings 

manufactured with improper material, if 

not addressed, could reduce the 

structural integrity of the airplane. 

The FAA is proposing this AD to 

address the unsafe condition on these 

products.

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–2416. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

EASA AD 2024–0171 specifies 

procedures for a special detailed 

inspection (SDI) (conductivity 

measurement, hardness test, and X-ray 

fluorescence (XRF) inspection) to 

determine the material tolerance of 

affected vertical to horizontal stabilizer 

junction fittings installed on group 1 or 

2 airplanes; repair of parts not within 

the tolerances of material AL7075–T73 

(except those within the tolerances of 

material AL7050–T7452); repetitive 

detailed visual inspections for any 

damage (including corrosion and dents) 

of each affected part that is within the 

tolerances of material AL7050–T7452 or 

is installed on a group 3 airplane; repair 

of damaged parts; and eventual 

replacement of any affected part that is 

within the tolerances of material 

AL7050–T7452 or installed on a group 

3 airplane. EASA AD 2024–0171 also 

specifies reporting the inspection results 

of the SDI to ATR. 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 require 

accomplishing the actions specified in 

EASA AD 2024–0171 described 

previously, except for any differences 

identified as exceptions in the 

regulatory text of this proposed 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, the FAA proposes to 

incorporate EASA AD 2024–0171 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2024–0171 

in its 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 2024–0171 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 2024–0171. 

Material required by EASA AD 2024– 

0171 for compliance will be available at 

regulations.gov under Docket No. FAA– 

2024–2416 after the FAA final rule is 

published. 

Interim Action 

The FAA considers that this proposed 

AD would be an interim action. The 

inspection reports specified in this 

proposed AD will provide the 

manufacturer additional data for 

determining the extent of the improper 

material usage, and to determine if 

further action is needed to address the 

unsafe condition. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 36 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Up to 26 work-hours × $85 per hour = $2,210 ................................................................ $0 Up to $2,210 ....... Up to $79,560. 

The FAA estimates the following 

costs to do any necessary on-condition 

actions 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 these 

on-condition actions: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per 

product 

Up to 523 work-hours × $85 per hour = $44,455 ................................................................................................... $6,340 $50,795 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition repairs specified in 

this proposed AD. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

operators. 

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to a penalty for failure to comply with 

a collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a currently valid 

OMB Control Number. The OMB 

Control Number for this information 

collection is 2120–0056. Public 

reporting for this collection of 

information is estimated to take 

approximately 1 hour per response, 

including the time for reviewing

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

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain ATR—GIE Avions de Transport 

Re ́gional Model ATR42 and ATR72 

airplanes. This proposed AD was 

prompted by a report that a flight deck 

emergency escape hatch was difficult to 

open due to the hose ends being 

connected to the hatch with incorrect 

parts, which could affect drainage of the 

hatch. This proposed AD would 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 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 December 16, 

2024. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following
