B1, B2, B3, C, D, and D1 helicopters that 

do not have a redesigned hold-down 

strap. AD 2014–02–05 corresponds with 

EASA AD 2009–0019, dated February 3, 

2009. 

Withdrawal of the NPRM constitutes 

only such action and does not preclude 

the FAA from further rulemaking on 

this issue, nor does it commit the FAA 

to any course of action in the future. 

Request To Revise the Applicability of 

the NPRM 

The European Aviation Safety Agency 

(now European Union Aviation Safety 

Agency (EASA) and American 

Eurocopter, in consultation with 

Eurocopter, requested that the 

applicability of the NPRM be limited to 

helicopters modified by a Geneva center 

console supplemental type certificate 

(STC). 

The FAA acknowledges these 

comments to the NPRM. However, the 

FAA considers the requested change to 

the NPRM moot by this withdrawal. 

FAA’s Conclusions 

Upon further consideration, the FAA 

has determined that the NPRM does not 

adequately address the identified unsafe 

condition and is unnecessary due to 

other rulemaking. Accordingly, the 

NPRM is withdrawn. 

Regulatory Findings 

Since this action only withdraws an 

NPRM, it is neither a proposed nor a 

final rule. This action therefore is not 

covered under Executive Order 12866, 

the Regulatory Flexibility Act, or DOT 

Regulatory Policies and Procedures (44 

FR 11034, February 26, 1979).

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 Airbus SAS Model A321–211, 

–231, and –232 airplanes. This proposed 

AD was prompted by a report of false 

drill starts found around the latch hook 

mounting holes of certain door frames of 

the fuselage due to erroneous 

manufacturing processes. This proposed 

AD would require a one-time inspection 

of the area around the latch hook 

mounting holes of the forward and aft 

door frames to detect damage from false 

drill starts, and repair if necessary, 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 April 22, 2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

Background 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0222, dated October 14, 2020 

(EASA AD 2020–0222) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for certain Airbus SAS Model A321– 

211, –231, and –232 airplanes. 

This proposed AD was prompted by 

a report of false drill starts found around 

the latch hook mounting holes of certain 

door frames of the fuselage due to 

erroneous manufacturing processes. 

These false drill starts were found 

around the latch hook mounting holes 

on frames 16 and 66 of the left- and 

right-hand sides of forward and aft 

passenger doors 1 and 4. 

The FAA is proposing this AD to 

address damage from false drill starts, 

which could result in reduced structural 

integrity of the airplane. See the MCAI 

for additional background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2020–0222 describes 

procedures for a one-time detailed 

inspection of the area around the latch 

hook mounting holes of the forward and 

aft door frames to detect damage from 

false drill starts, and repair of any 

damage found. 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 and Requirements 

of This Proposed AD 

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 the State 

of Design Authority, the FAA has been 

notified of the unsafe condition 

described in the MCAI referenced 

above. The FAA is proposing this AD 

because the FAA evaluated all the 

relevant information and determined 

the unsafe condition described 

previously is likely to exist or develop 

in other products of the same type 

design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

EASA AD 2020–0222 described 

previously, as incorporated by 

reference, except for any differences 

identified as exceptions in the 

regulatory text of this AD. 

Clarification of Compliance Times to 

Certain Proposed AD Requirements 

Although EASA AD 2020–0222 does 

not specifically state compliance times 

for the corrective actions required by 

paragraph (2) of EASA AD 2020–0222, 

paragraph (2) of EASA AD 2020–0222 

does specify to accomplish applicable 

corrective actions within the 

compliance time as specified in Airbus 

Service Bulletin A320–53–1473, dated 

December 20, 2019. Airbus Service 

Bulletin A320–53–1473, dated 

December 20, 2019, specifies the 

compliance times for these actions are 

before further flight. Therefore, 

paragraph (g) of this proposed AD 

would require the corrective actions to 

be done before further flight. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA initially worked with 

Airbus and EASA to develop a process 

to use certain EASA ADs as the primary 

source of information for compliance 

with requirements for corresponding 

FAA ADs. The FAA has since 

coordinated with other manufacturers 

and civil aviation authorities (CAAs) to 

use this process. As a result, EASA AD 

2020–0222 will be incorporated by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2020–0222 

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 

the EASA AD 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 the EASA AD. Service 

information specified in EASA AD 

2020–0222 that is required for 

compliance with EASA AD 2020–0222 

will be available on the internet at 

https://www.regulations.gov by 

searching for and locating Docket No. 

FAA–2021–0128 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 21 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 

14 work-hours × $85 per hour = $1,190 ..................................................................................... $0 $1,190 $24,990 

* Table does not include estimated costs for reporting. 

The FAA estimates that it would take 

about 1 work-hour per product to 

comply with the proposed reporting 

requirement in this proposed AD. The 

average labor rate is $85 per hour. Based 

on these figures, the FAA estimates the 

cost of reporting the inspection results 

on U.S. operators to be $1,785, or $85 

per product. 

The FAA estimates the following 

costs to do any necessary on-condition 

repairs 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 repairs: 


jbell on DSKJLSW7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Proposed Rules 13231 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per 

product 

Up to 42 work-hours × $85 per hour = $3,570 (per door) ...................................................................................... * $0 Up to $3,570. 

* The FAA has received no definitive data on which to base the parts cost estimates for the on-condition repairs specified in this proposed AD. 

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 

operators. The FAA does not control 

warranty coverage for affected operators. 

As a result, the FAA has included all 

known costs in the cost estimate. 

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 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 current valid 

OMB control number. The control 

number for the collection of information 

required by this proposed AD is 2120– 

0056. The paperwork cost associated 

with this proposed AD has been 

detailed in the Costs of Compliance 

section of this document and includes 

time for reviewing instructions, as well 

as completing and reviewing the 

collection of information. Therefore, all 

reporting associated with this proposed 

AD is mandatory. Comments concerning 

the accuracy of this burden and 

suggestions for reducing the burden 

should be directed to Information 

Collection Clearance Officer, Federal 

Aviation Administration, 10101 

Hillwood Parkway, Fort Worth, TX 

76177–1524. 

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.

Organization Approval (DOA). If approved by 

the DOA, the approval must include the 

DOA-authorized signature. 

(3) Required for Compliance (RC): Except 

as required by paragraph (i)(2) of this AD, if 

any service information contains procedures 

or tests that are identified as RC, those 

procedures and tests must be done to comply 

with this AD; any procedures or tests that are 

not identified as RC are recommended. Those 

procedures and tests that are not identified 

as RC may be deviated from using accepted 

methods in accordance with the operator’s 

maintenance or inspection program without 

obtaining approval of an AMOC, provided 

the procedures and tests identified as RC can 

be done and the airplane can be put back in 

an airworthy condition. Any substitutions or 

changes to procedures or tests identified as 

RC require approval of an AMOC. 

(4) Paperwork Reduction Act Burden 

Statement: 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

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede airworthiness directive (AD) 

2015–25–04 for Agusta S.p.A (now 

Leonardo S.p.a.) Model A109A and 

A109A II helicopters. AD 2015–25–04 

requires inspecting the slider assembly 

pitch control (slider) for play and 

replacing the slider if the play exceeds 

certain limits. Since the FAA issued AD 

2015–25–04, further investigation 

determined the play was caused by a 

manufacturing issue. This proposed AD 

would retain certain requirements of AD 

2015–25–04, require replacing certain 

part-numbered sliders as a terminating 

action for the inspections, and prohibit 

installing the affected part on any 

helicopter. The actions of this proposed 

AD are intended to address an unsafe 

condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by April 22, 2021. 

ADDRESSES: You may send comments by
