Airworthiness Directives; Airbus 

Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Helicopters Model AS350B, 

AS350BA, AS350B1, AS350B2, 

AS350B3, AS350D, AS355E, AS355F, 

AS355F1, AS355F2, AS355N, and 

AS355NP helicopters. This AD was 

prompted by a report of reduced yaw 

control, during an approach for landing, 

that resulted from rupture of the tail 

rotor gearbox (TGB) actuating rod and 

uncoupling of the steel sleeve from 

inside the external aluminum tube. This 

AD requires dye penetrant inspecting 

certain TGB actuating rods for a crack, 

and depending on the inspection 

results, replacing the TGB actuating rod, 

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 is effective October 6, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of October 6, 2021.

SUPPLEMENTARY INFORMATION: 

Background 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2019–0060, dated March 20, 2019 

(EASA AD 2019–0060) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for all Airbus Helicopters Model AS350 

B, AS350 BA, AS350 BB, AS350 B1, 

AS350 B2, AS350 B3, AS350 D, AS355 

E, AS355 F, AS355 F1, AS355 F2, 

AS355 N and AS355 NP helicopters. 

Model AS350 BB helicopters 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 helicopters in the 

applicability. Although EASA AD 2019– 

0060 applies to all helicopters identified 

in EASA AD 2019–0060, this AD 

applies to helicopters with an affected 

part installed instead. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Airbus Helicopters 

Model AS350B, AS350BA, AS350B1, 

AS350B2, AS350B3, AS350D, AS355E, 

AS355F, AS355F1, AS355F2, AS355N, 

and AS355NP helicopters. The NPRM 

published in the Federal Register on 

May 18, 2021 (86 FR 26857). The NPRM 

was prompted by a report of reduced 

yaw control, during an approach for 

landing, that resulted from rupture of 

the TGB actuating rod and uncoupling 

of the steel sleeve from inside the 

external aluminum tube. The NPRM 

proposed to require dye penetrant 

inspecting certain TGB actuating rods 

for a crack, and depending on the 

inspection results, replacing the TGB 

actuating rod, as specified in an EASA 

AD. 

The FAA is issuing this AD to address 

failure of a TGB actuating rod, which 

could result in loss of yaw control of the 

helicopter. See the MCAI for additional 

background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The following presents 

the comment received on the NPRM and 

the FAA’s response to the comment. 

Request To Not Refer to Other Sources 

for Approved Data 

A commenter requested that the 

proposed AD not reference a European 

AD or service bulletin as approved data. 

The commenter stated the proposed AD 

should contain all the data required to 

perform the inspection in its entirety so 

that an inspector does not have to 

research data from other sources. 

The FAA does not agree with the 

commenter because the approved data is 

available to inspectors. EASA AD 2019– 

0060 is incorporated by reference. 

Incorporation by reference (IBR) allows 

Federal agencies to comply with the 

requirement to publish rules in the 

Federal Register by referring to 

materials already published elsewhere. 

The legal effect of IBR is that the 

material is treated as if it were 

published in the Federal Register. This 

material, like any other properly issued 

rule, has the force and effect of law. 

Congress authorized IBR in the Freedom 

of Information Act (5 U.S.C. 552), in 

part, to reduce the volume of material 

published in the Federal Register and 

the Code of Federal Regulations (CFR). 

After an FAA final rule is published, 

the required service information is then 

posted to https://www.regulations.gov. 

EASA AD 2019–0060 and the service 

information specified in EASA AD 

2019–0060 that is required for 

compliance with EASA AD 2019–0060 

can be found on the internet at https:// 

www.regulations.gov by searching for 

and locating Docket No. FAA 2021– 

0369. The FAA has not changed this AD 

in this regard. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting this 

final rule as proposed, except for minor 

editorial changes. The FAA has 

determined that these minor changes: 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 86, No. 167 / Wednesday, September 1, 2021 / Rules and Regulations 48903 

• Are consistent with the intent that 

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2019–0060 describes 

procedures for dye penetrant inspecting 

certain TGB actuating rods for a crack, 

and depending on the inspection 

results, replacing the TGB actuating rod. 

EASA AD 2019–0060 also describes 

procedures for marking each TGB 

actuating rod, reporting information, 

and for certain helicopters, ensuring the 

correct interface between certain TGB 

actuating rods and bearings. 

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. 

Differences Between This AD and the 

MCAI 

EASA AD 2019–0060 specifies 

‘‘AS350 SB [service bulletin] No. 67.10 

Revision 1’’ and ‘‘AS355 SB No. 67.09 

Revision 2’’ as Airbus Helicopters (AH) 

service bulletins; however this AD 

identifies those service bulletins as 

Aerospatiale service bulletins. 

EASA AD 2019–0060 specifies the 

date for ‘‘AS355 SB No. 67.09 Revision 

2,’’ as ‘‘March 28, 1989;’’ however, this 

AD identifies the date as ‘‘October 

1989.’’ 

Part Marking Clarification 

Where paragraph (2) of EASA AD 

2019–0060 specifies ‘‘mark each 

affected part (all rods, regardless of the 

status with respect to the dye penetrant 

inspection),’’ this AD requires marking 

TGB actuating rods identified in 

paragraphs (c)(1) through (9) of this AD 

regardless of their manufacturing date. 

The manufacturing dates in Table 1 of 

EASA AD 2019–0060 are used only to 

indicate the parts on which the dye 

penetrant inspection specified in 

paragraph (1) of EASA AD 2019–0060 is 

done; the manufacturing dates do not 

impact the parts on which the marking 

specified in paragraph (2) of EASA AD 

2019–006 must be done. 

Interim Action 

The FAA considers this AD interim 

action. If final action is later identified, 

the FAA might consider further 

rulemaking then. 

Costs of Compliance 

The FAA estimates that this AD 

affects 950 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 

6 work-hours × $85 per hour = $510 .......................................................................................... $0 $510 $484,500 

* Table does not include estimated costs for reporting. 

The FAA estimates that it would take 

about 1 hour per product to comply 

with the reporting requirement in this 

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 $80,750, or $85 per product. 

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 helicopters that might need 

these on-condition actions: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per 

product 

Up to 16 work-hours × $85 per hour = $1,360 .................................................................................................... $2,590 Up to $3,950 

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 AD is 2120–0056. The 

paperwork cost associated with this 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 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 Pkwy., 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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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.

History 

The FAA published a notice of 

proposed rulemaking in the Federal 

Register (86 FR 24797; May 10, 2021) 

for Docket No. FAA–2021–0235 to 

revoke the Class E Surface Airspace at 

the St. Clair County International 

Airport, Port Huron, MI. Interested 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on the proposal to the 

FAA. No comments were received. 

Class E airspace designations are 

published in paragraph 6005 of FAA 

Order 7400.11E, dated July 21, 2020, 

and effective September 15, 2020, which 

is incorporated by reference in 14 CFR 

71.1. The Class E airspace designations 

listed in this document will be 

published subsequently in the Order. 

Availability and Summary of 

Documents for Incorporation by 

Reference 

This document amends FAA Order 

7400.11E, Airspace Designations and 

Reporting Points, dated July 21, 2020, 

and effective September 15, 2020. FAA 

Order 7400.11E is publicly available as 

listed in the ADDRESSES section of this 

document. FAA Order 7400.11E lists 

Class A, B, C, D, and E airspace areas, 

air traffic service routes, and reporting 

points. 

The Rule 

This amendment to 14 CFR part 71 

revokes the Class E surface airspace at 

St. Clair County International Airport, 

Port Huron, MI, as it is no longer 

needed. 

This action is the result of an airspace 

review caused by the decommissioning 

of the RCO, which provides navigation 

information for the instrument 

procedures this airport. 

FAA Order 7400.11, Airspace 

Designations and Reporting Points, is 

published yearly and effective on 

September 15. 

Regulatory Notices and Analyses 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current, is non-controversial and 

unlikely to result in adverse or negative 

comments. It, therefore: (1) Is not a 

‘‘significant regulatory action’’ under 

Executive Order 12866; (2) is not a 

‘‘significant rule’’ under DOT 

Regulatory Policies and Procedures (44 

FR 11034; February 26, 1979); and (3) 

does not warrant preparation of a 

regulatory evaluation as the anticipated 

impact is so minimal. Since this is a 

routine matter that only affects air traffic 

procedures and air navigation, it is 

certified that this rule, when 

promulgated, does not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act. 

Environmental Review 

The FAA has determined that this 

action qualifies for categorical exclusion 

under the National Environmental 

Policy Act in accordance with FAA 

Order 1050.1F, ‘‘Environmental 

Impacts: Policies and Procedures,’’ 

paragraph 5–6.5.a. This airspace action 

is not expected to cause any potentially 

significant environmental impacts, and 

no extraordinary circumstances exist 

that warrant preparation of an 

environmental assessment.
