AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2019–26–11, which applies to certain 

Airbus SAS Model A319–112, –115, and 

–132; A320–214, –216, –232, –233, 

–251N, and –271N; and A321–211, 

–231, –232, –251N, and –253N 

airplanes; and AD 2021–23–15, which 

applies to certain Airbus SAS Model 

A319–111, –112, –113, –114, –115, 

–131, –132, and –133; A320–211, –212, 

–214, –216, –231, –232, and –233; and 

A321–111, –112, –131, –211, –212, 

–213, –231, and –232 airplanes. AD 

2019–26–11 requires replacing the 

affected bumpers with serviceable 

bumpers. AD 2021–23–15 requires 

modifying the waste compartment door 

of each affected galley. Since the FAA 

issued AD 2019–26–11 and AD 2021– 

23–15, it was determined that additional 

airplanes are subject to the unsafe 

conditions described in those ADs. This 

proposed AD would continue to require 

the actions in AD 2019–26–11 and AD 

2021–23–15, and would add airplanes 

to the applicability, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is proposed for 

incorporation by reference. 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 August 5, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Background 

The FAA issued AD 2019–26–11, 

Amendment 39–21022 (85 FR 6755, 

February 6, 2020) (AD 2019–26–11), 

which applies to certain Airbus SAS 

Model A319–112, A319–115, A319–132, 

A320–214, A320–216, A320–232, A320– 

233, A320–251N, A320–271N, A321– 


jspears on DSK121TN23PROD with PROPOSALS1
Federal Register / Vol. 87, No. 118 / Tuesday, June 21, 2022 / Proposed Rules 36779 

211, A321–231, A321–232, A321–251N, 

and A321–253N airplanes. AD 2019– 

26–11 requires replacing affected 

container/galley end stop bumpers with 

serviceable bumpers. The FAA issued 

AD 2019–26–11 to address deformed 

end stops, which could break or lose 

their function to maintain the container/ 

galley in position on the airplane. This 

condition, if not corrected, could lead to 

container/galley detachment under 

certain forward loading conditions, 

possibly resulting in injury to airplane 

occupants. 

The FAA also issued AD 2021–23–15, 

Amendment 39–21813 (86 FR 68894, 

December 6, 2021) (AD 2021–23–15), 

which applies to certain Airbus SAS 

Model A319–111, –112, –113, –114, 

–115, –131, –132, and –133 airplanes; 

Model A320–211, –212, –214, –216, 

–231, –232, and –233 airplanes; and 

Model A321–111, –112, –131, –211, 

–212, –213, –231, and –232 airplanes. 

AD 2021–23–15 requires modifying the 

waste compartment door of each 

affected galley. The FAA issued AD 

2021–23–15 to address failure of the 

galley door and release of trolleys 

during a rejected take-off or an 

emergency landing, which could result 

in injury to occupants and damage to 

the airplane. 

Actions Since AD 2019–26–11 and AD 

2021–23–15 Were Issued 

Since the FAA issued AD 2019–26–11 

and AD 2021–23–15, it was determined 

that additional airplanes are subject to 

the unsafe conditions addressed by AD 

2019–26–11 and AD 2021–23–15. 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2022–0026, 

dated February 16, 2022 (EASA AD 

2022–0026) (also referred to as the 

MCAI), to correct an unsafe condition 

for certain Airbus SAS Model A319– 

111, A319–112, A319–113, A319–114, 

A319–115, A319–131, A319–132, A319– 

133, A320–211, A320–212, A320–214, 

A320–215, A320–216, A320–231, A320– 

232, A320–233, A320–251N, A320– 

271N, A321–111, A321–112, A321–131, 

A321–211, A321–212, A321–213, A321– 

231, A321–232, A321–251N and A321– 

253N airplanes. Model A320–215 

airplanes are not certificated by the FAA 

and are not included on the U.S. type 

certificate data sheet; this AD therefore 

does not include those airplanes in the 

applicability. 

This proposed AD was prompted by 

a report that during re-engineering of 

galley G5, a 9G forward full scale 

qualification test was performed, and 

the door of the waste compartment 

opened before the required load was 

reached, and by reports of finding 

container/galley end stop bumpers 

damaged in service. This proposed AD 

was also prompted by the determination 

that additional airplanes are subject to 

the unsafe condition. The FAA is 

proposing this AD to address potential 

failure of the galley door and release of 

waste bins during a rejected take-off or 

an emergency landing, and potential 

container detachment from the galley 

under certain forward loading 

conditions, possibly resulting in damage 

to the airplane and injury to occupants. 

See the MCAI for additional background 

information. 

Explanation of Retained Requirements 

Although this proposed AD does not 

explicitly restate the requirements of AD 

2019–26–11 and AD 2021–23–15, this 

proposed AD would retain all of the 

requirements of AD 2019–26–11 and AD 

2021–23–15. Those requirements are 

referenced in EASA AD 2022–0026, 

which, in turn, is referenced in 

paragraph (g) of this proposed AD. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2022–0026 specifies 

procedures for modifying the affected 

galleys by replacing the affected 

bumpers with serviceable bumpers; for 

modifying the waste compartment door 

of each affected galley by installing a 

door catch bracket and a new striker, 

and for re-identifying the affected 

galleys. 

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 

These products have been approved 

by the aviation authority of another 

country and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the State 

of Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI and service information 

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 these same type designs. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

EASA AD 2022–0026 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 2022–0026 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2022–0026 

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 2022–0026 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 2022–0026. 

Service information required by EASA 

AD 2022–0026 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2022–0689 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 1,507 airplanes of U.S. 

registry. The FAA estimates the 

following costs to comply with this 

proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Retained actions from AD 2019–26–11 

(274 airplanes).

Up to 54 work-hours × $85 per hour = Up 

to $4,590.

$0 Up to $4,590 ..... Up to $1,257,660.

ESTIMATED COSTS FOR REQUIRED ACTIONS—Continued 

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Retained actions from AD 2021–23–15 

(141 airplanes).

New proposed actions (Up to 1,092 airplanes).Up to 59 work-hours × $85 per hour = Up 

to $5,105.

0 Up to $5,105 ..... Up to $5,476,380. 

According to the manufacturer, some 

or all of the costs of this proposed AD 

may be covered under warranty, thereby 

reducing the cost impact on affected 

individuals. The FAA does not control 

warranty coverage for affected 

individuals. As a result, the FAA has 

included all known costs in the cost 

estimate. 

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 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference,

Airworthiness Directives; General 

Electric Company Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

General Electric Company (GE) CT7–8A 

model turboshaft engines. This 

proposed AD was prompted by the 

manufacturer revising the airworthiness 

limitations section (ALS) of the existing 

engine maintenance manual (EMM) to 

incorporate reduced life limits for 

certain stage 1 turbine aft cooling plates, 

stage 2 turbine forward cooling plates, 

turbine interstage seals, and stage 4 

turbine disks. This proposed AD would 

require revising the ALS of the existing 

EMM and the operator’s existing 

approved maintenance or inspection 

program, as applicable, to incorporate 

reduced life limits for these parts. 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 August 5, 2022.
