Airworthiness Directives; Airbus 

Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Airbus Helicopters Model AS355E, 

AS355F, AS355F1, AS355F2, AS355N 

and AS355NP helicopters; and certain 

Model AS350B3 helicopters. This AD 

was prompted by a report that, during 

an unscheduled post-flight inspection of 

the tail cone area, a crack was found in 

the spar of the upper part of the vertical 

fin and fractures were found in the two 

front attachment screws. This AD 

requires repetitive visual inspections of 

the right-hand side of the vertical fin 

spar for discrepancies (cracking), and 

corrective action if necessary, 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 becomes effective 

March 23, 2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 23, 2021. 

The FAA must receive comments on 

this AD by April 22, 2021.

SUPPLEMENTARY INFORMATION: 

Discussion 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0186, dated August 20, 2020 

(EASA AD 2020–0186) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for all Airbus Helicopters Model 

AS355E, AS355F, AS355F1, AS355F2, 

AS355N and AS355NP helicopters; and 

certain Model AS350B3 helicopters. 

This AD was prompted by a report 

that, during an unscheduled post-flight 

inspection of the tail cone area of an 

Airbus Helicopters Model AS355NP 

helicopter, a crack was found in the spar 

of the upper part of the vertical fin and 

fractures were found in the two front 

attachment screws. Airbus Helicopters 

Model AS350B3 helicopters have a 

similar vertical fin configuration and are 

subject to comparable load levels as the 

affected Model AS355NP helicopter, 

therefore, this model may be subject to 

the same unsafe condition revealed on 

the Model AS355NP helicopter. The 

FAA is issuing this AD to address 


jbell on DSKJLSW7X2PROD with RULES
13166 Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Rules and Regulations 

cracking in the spar of the upper part of 

the vertical fin and fractures in the front 

attachment screws. This condition 

could lead to in-flight separation of the 

upper part of the vertical fin, resulting 

in loss of control of the helicopter. See 

the MCAI for additional background 

information. 

Related IBR Material Under 1 CFR Part 

51 

EASA AD 2020–0186 describes 

procedures for, among other actions, 

repetitive visual inspections of the righthand side of the vertical fin spar for 

cracking and corrective action. The 

corrective action includes repair. EASA 

AD 2020–0186 also describes 

procedures for an optional modification, 

which terminates the repetitive 

inspections. 

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, the FAA has been 

notified of the unsafe condition 

described in the MCAI referenced 

above. The FAA is issuing this AD after 

evaluating all pertinent information and 

determining that the unsafe condition 

exists and is likely to exist or develop 

on other products of these same type 

designs. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in EASA AD 2020– 

0186, described previously, as 

incorporated by reference, except for 

any differences identified as exceptions 

in the regulatory text of this AD and 

except as discussed under ‘‘Differences 

Between this AD and the MCAI.’’ 

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 

2020–0186 will be incorporated by 

reference in the FAA final rule. This AD 

would, therefore, require compliance 

with EASA AD 2020–0186 in its 

entirety, through that incorporation, 

except for any differences identified as 

exceptions in the regulatory text of this 

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 

2020–0186 that is required for 

compliance with EASA AD 2020–0186 

is available on the internet at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

0094. 

Differences Between This AD and the 

MCAI 

Paragraph (2) of EASA AD 2020–0186 

specifies doing repetitive cleaning and 

detailed inspections of the vertical fin 

spar and vertical fin upper attachments. 

The actions specified in paragraph (2) of 

EASA AD 2020–0186 are not required 

by this AD because the planned 

compliance time for those actions 

would allow enough time to provide 

notice and opportunity for prior public 

comment on the merits of those actions. 

The FAA is considering additional 

rulemaking to address the actions 

specified in paragraph (2) of EASA AD 

2020–0186. 

FAA’s Justification and Determination 

of the Effective Date 

Section 553(b)(3)(B) of the 

Administrative Procedure Act (5 U.S.C.) 

authorizes agencies to dispense with 

notice and comment procedures for 

rules when the agency, for ‘‘good cause’’ 

finds that those procedures are 

‘‘impracticable, unnecessary, or contrary 

to the public interest.’’ Under this 

section, an agency, upon finding good 

cause, may issue a final rule without 

seeking comment prior to the 

rulemaking. 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies waiving notice 

and comment prior to adoption of this 

rule because cracking in the spar of the 

upper part of the vertical fin and 

fractures in the front attachment screws 

could lead to in-flight separation of the 

upper part of the vertical fin, resulting 

in loss of control of the helicopter. In 

addition, the initial inspection is 

required within 55 hours time-inservice, a time period of less than 3 

months based on the average flight-hour 

utilization rate of these helicopters. 

Therefore, notice and opportunity for 

prior public comment are impracticable 

and contrary to public interest pursuant 

to 5 U.S.C. 553(b)(3)(B). In addition, the 

FAA finds that good cause exists 

pursuant to 5 U.S.C. 553(d) for making 

this amendment effective in less than 30 

days. 

Comments Invited 

The FAA invites you to send any 

written relevant data, views, or 

arguments about this AD. Send your 

comments to an address listed under 

ADDRESSES. Include ‘‘Docket No. FAA– 

2021–0094; Project Identifier MCAI– 

2021–00100–R’’ at the beginning of your 

comments. The most helpful comments 

reference a specific portion of the AD, 

explain the reason for any 

recommended change, and include 

supporting data. The FAA will consider 

all comments received by the closing 

date and may amend this AD because of 

those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to https://

www.regulations.gov, including any 

personal information you provide. The 

agency will also post a report 

summarizing each substantive verbal 

contact received about this AD. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this AD contain 

commercial or financial information 

that is customarily treated as private, 

that you actually treat as private, and 

that is relevant or responsive to this AD, 

it is important that you clearly designate 

the submitted comments as CBI. Please 

mark each page of your submission 

containing CBI as ‘‘PROPIN.’’ The FAA 

will treat such marked submissions as 

confidential under the FOIA, and they 

will not be placed in the public docket 

of this AD. Submissions containing CBI 

should be sent to Kathleen Arrigotti, 

Aviation Safety Engineer, Large Aircraft 

Section, International Validation 

Branch, FAA, 2200 South 216th St., Des 

Moines, WA 98198; phone and fax: 206– 

231–3218; email: kathleen.arrigotti@

faa.gov. Any commentary that the FAA 

receives that is not specifically 


jbell on DSKJLSW7X2PROD with RULES
Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Rules and Regulations 13167 

designated as CBI will be placed in the 

public docket for this rulemaking. 

Regulatory Flexibility Act (RFA) 

The requirements of the RFA do not 

apply when an agency finds good cause 

pursuant to 5 U.S.C. 553 to adopt a rule 

without prior notice and comment. 

Because the FAA has determined that it 

has good cause to adopt this rule 

without notice and comment, RFA 

analysis is not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 650 helicopters 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 

7 work-hour × $85 per hour = $595 ............................................................................................ $0 $595 $386,750

ESTIMATED COSTS FOR OPTIONAL ACTIONS

Labor cost Parts cost Cost per 

product 

8 work-hours × $85 per hour = $680 ...................................................................................................................... $7,300 $7,980 

The FAA estimates the following 

costs to do any necessary on-condition 

action that would be required based on 

the results of any required or optional 

actions. The FAA has no way of 

determining the number of helicopters 

that might need this on-condition 

action: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement ................................................................. 4 work-hours × $85 per hour = $340 ........................... $17,052 $17,392 

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 AD 

would not have federalism implications 

under Executive Order 13132. This 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 regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

The Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

2021–04–15 Airbus Helicopters: 

Amendment 39–21437; Docket No. 

FAA–2021–0094; Project Identifier 

MCAI–2021–00100–R. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective March 23, 2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Airbus Helicopters 

specified in paragraph (c)(1) and (2) of this 

AD, certificated in any category. 

(1) Model AS355E, AS355F, AS355F1, 

AS355F2, AS355N, and AS355NP 

helicopters, all serial numbers. 

(2) Model AS350B3 helicopters, all serial 

numbers except those that have embodied 

Modification 07.3148 in production, or 

Eurocopter AS350 Service Bulletin 55.00.14 

(any revision) in service. 

(d) Subject 

Joint Aircraft System Component (JASC) 

Code 5531, Vertical Stabilizer, Spar/Rib. 

(e) Reason 

This AD was prompted by a report that, 

during an unscheduled post-flight inspection 

of the tail cone area of an Airbus Helicopters 

Model AS355NP helicopter, a crack was 

found in the spar of the upper fin and 

fractures were found in the two front 

attachment screws. The FAA is issuing this 

AD to address cracking in the spar of the 

upper part of the vertical fin and fractures in 

the front attachment screws. This condition 

could lead to in-flight separation of the upper 

part of the vertical fin, resulting in loss of 

control of the helicopter.

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

2020–0186 does not apply to this AD. 

(3) The actions specified in paragraph (2) 

of EASA AD 2020–0186 are not required by 

this AD. 

(4) Where paragraph (3) of EASA AD 2020– 

0186 specifies to contact the manufacturer for 

approved repair instructions, for this AD, if 

any cracking is detected during any 

inspection, repair before further flight using 

a method approved by the Manager, 

International Validation Branch, FAA. For a 

repair method to be approved by the 

Manager, International Validation Branch, as 

required by this paragraph, the Manager’s 

approval letter must specifically refer to this 

AD. 

(5) Where EASA AD 2020–0186 refers to 

flight hours (FH), this AD requires using 

hours time-in-service. 

(6) Where the service information referred 

to in EASA AD 2020–0186 specifies to 

perform a visual inspection and ‘‘if in doubt’’ 

remove the rear and the tail rotor gear box 

(TGB) fairings to perform a detailed 

inspection and ‘‘carry out’’ a dye-penetrant 

inspection, those actions are required by this 

AD if any crack indication (e.g., paint chips, 

dents, or swelling) is found during any 

inspection done without removing the rear 

and the TGB fairings. 

(7) Although the service information 

referenced in EASA AD 2020–0186 specifies 

to scrap certain parts, this AD requires 

removing those parts from service instead.

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of the airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it would 

modify the VOR Federal airway route 

structure in the eastern United States to 

maintain the efficient flow of air traffic.
