Airworthiness Directives; Airbus SAS 

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 Airbus SAS Model A318 series 

airplanes; 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. 

This proposed AD was prompted by 

reports that during inspections 

accomplished in accordance with 

certain airworthiness limitation items 

(ALIs), cracks were detected in double 

joggle areas at frame (FR) 16 and FR20, 

right hand and left hand sides. This 

proposed AD would require repetitive 

special detailed inspections of certain 

areas and applicable on-condition 

actions, as specified in a European 

Union Aviation Safety Agency (EASA) 

AD. 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 March 25, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0227, 

dated October 11, 2021 (EASA AD 

2021–0227) (also referred to as the 

MCAI), to correct an unsafe condition 

for certain Airbus SAS Model A318 

series airplanes; 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. 

This proposed AD was prompted by 

reports that during inspections 

accomplished in accordance with ALI 

tasks 531153 and 531155, cracks were 

detected in the double joggle areas at 

FR16 and FR20, right hand and left 

hand sides. The FAA is proposing this 


khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 87, No. 26 / Tuesday, February 8, 2022 / Proposed Rules 7063 

AD to address cracks in these areas, 

which, if not detected and corrected, 

could reduce the structural integrity of 

the fuselage. See the MCAI for 

additional background information. 

Other Relevant Rulemaking 

AD 2020–20–05, Amendment 39– 

21261 (85 FR 65197, October 15, 2020) 

(AD 2020–20–05) applies to Model 

A318–111, –112, –121, and –122 

airplanes; Model A319–111, –112, –113, 

–114, –115, –131, –132, –133, –151N, 

and –153N airplanes; Model A320–211, 

–212, –214, –216, –231, –232, –233, 

–251N, –252N, –253N, –271N, –272N, 

and –273N airplanes; and Model A321–

–253N, –253NX, –271N, –271NX, 

–272N, and –272NX airplanes. AD 

2020–20–05 requires incorporating new 

or more restrictive airworthiness 

limitations. Accomplishment of the 

proposed actions would terminate ALI 

Tasks 531153–02–1, 531153–02–2, 

531155–02–1 and 531155–02–2, as 

required by paragraph (i) of AD 2020– 

20–05 for Model A318 series airplanes; 

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 

only. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0227 specifies 

procedures for repetitive special 

detailed inspections (rototest 

inspections) of double joggle areas at 

FR16 and FR20, right hand and left 

hand sides for cracking, applicable oncondition actions (repair) and an 

optional modification of the double 

joggle area, which terminates the 

repetitive inspections. The modification 

includes a rotating probe inspection of 

certain fastener holes for cracks, a check 

of the fastener holes for a minimum 

diameter, and applicable on-condition 

actions (repair and oversizing holes). 

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 is 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 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 2021–0227 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 2021–0227 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2021–0227 

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 2021–0227 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 2021–0227. 

Service information required by EASA 

AD 2021–0227 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2022–0091 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this proposed 

AD would affect 1,549 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 55 work-hours × $85 per hour = $4,675 ........................ $0 Up to $4,675 ........................... Up to $7,241,575. 

ESTIMATED COSTS FOR OPTIONAL ACTIONS

Labor cost Parts cost Cost per 

product 

60 work-hours × $85 per hour = $5,100 ................................................................................................................. $1,624 $6,724 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition repairs specified in 

this proposed 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. 


khammond on DSKJM1Z7X2PROD with PROPOSALS
7064 Federal Register / Vol. 87, No. 26 / Tuesday, February 8, 2022 / Proposed Rules 

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, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:

reduce the structural integrity of the fuselage. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, EASA AD 2021–0227. 

(h) Exceptions to EASA AD 2021–0227 

(1) Where EASA AD 2021–0227 refers to its 

effective date, this AD requires using the 

effective date of this AD. 

(2) The ‘‘Remarks’’ section of EASA AD 

2021–0227 does not apply to this AD. 

(3) Where paragraph (2) of EASA AD 2021– 

0227 specifies to ‘‘contact Airbus for 

approved repair instructions and, within the 

compliance time specified therein, 

accomplish those instructions accordingly’’ if 

any cracks are detected, for this AD if any 

cracking is detected, the cracking must be 

repaired before further flight using a method 

approved by Airbus SAS’s EASA Design 

Organization Approval (DOA). If approved by 

the DOA, the approval must include the 

DOA-authorized signature. 

(4) Where paragraphs (3) and (4) of EASA 

AD 2021–0227 specify ‘‘Airbus approved 

repair instructions,’’ or ‘‘post-repair 

inspection instructions approved by Airbus,’’ 

for this AD, to be acceptable for credit, the 

repair instructions must be approved by 

Airbus SAS’s EASA Design Organization 

Approval (DOA). If approved by the DOA, 

the approval must include the DOAauthorized signature. 

(i) No Reporting Requirement 

Although the service information 

referenced in EASA AD 2021–0227 specifies 

to submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

(j) Terminating Action for Certain 

Requirements in AD 2020–20–05 

Accomplishing the initial inspections 

required by this AD terminates ALI Tasks 

531153–02–1, 531153–02–2, 531155–02–1 

and 531155–02–2, as required by paragraph

Airworthiness Directives; Viking Air 

Limited (Type Certificate Previously 

Held by Bombardier Inc. and de 

Havilland, Inc.) Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

64–09–03, which applies to all de 

Havilland (type certificate now held by 

Viking Air Limited) Model DHC–2 

‘‘Beaver’’ airplanes. AD 64–09–03 

requires inspecting the aileron mass 

balance weight arms for cracks and 

corrosion and replacing any damaged 

part. Since the FAA issued AD 64–09– 

03, Transport Canada superseded its 

mandatory continuing airworthiness 

information (MCAI) to correct an unsafe 

condition on these products. This 

proposed AD would require establishing 

a corrosion prevention and control 

program to identify and correct 

corrosion. This proposed AD would also 

require completing all of the initial tasks 

identified in the program and reporting 

corrosion findings to Viking. The 

proposed corrosion prevention and 

control program would include the 

inspection of the aileron balance weight 

arms required by AD 64–09–03. 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 March 25, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

https://www.regulations.gov. Follow the 

instructions for submitting comments.

Background 

The FAA issued AD 64–09–03, 

Amendment 718 (29 FR 5390; April 22, 

1964) (AD 64–09–03) for all de 

Havilland (type certificate now held by 

Viking Air Limited) Model DHC–2 

‘‘Beaver’’ airplanes. AD 64–09–03 

requires repetitively inspecting the 

aileron mass balance weight arms for 

cracks and corrosion and replacing any 

damaged part. AD 64–09–03 resulted 

from cracks and corrosion found on 

aileron mass balance weight arm part 

numbers (P/Ns) C2WA151, C2WA152, 

C2WA127, and C2WA128. 

Actions Since AD 64–09–03 Was Issued 

Since the FAA issued AD 64–09–03, 

the type certificate holder for Model 

DHC–2 airplanes changed from de 

Havilland to Viking Air Limited. 

Transport Canada, which is the aviation 

authority for Canada, superseded its 

prior ADs on this unsafe condition and 

issued AD CF–2019–25, dated July 5, 

2019 (referred to after this as ‘‘the 

MCAI’’), to correct an unsafe condition 

for all serial-numbered Viking Air 

Limited Model DHC–2 Mk. I, DHC–2 

Mk. II, and DHC–2 Mk. III airplanes. 

The MCAI states: 

Service experience indicates that aging 

aircraft are more likely to be affected by 

corrosion. Viking Air Limited (Viking), as 

Type Certificate holder for DHC–2, has 

developed a supplementary inspection and 

corrosion control program which identifies 

specific area that must be inspected to ensure 

the corrosion-related degradation does not
