AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2021–04–21, which applies to certain 

Airbus Helicopters Model EC120B 

helicopters. AD 2021–04–21 requires an 

inspection of the attachment bolts of the 

main rotor (MR) hub scissors assembly 

for discrepancies and repair if 

necessary; part marking of the 

attachment bolts of the MR hub scissors 

assembly; and repetitive inspections of 

the part marking of the attachment bolts, 

and repair if necessary. Since the FAA 

issued AD 2021–04–21, the FAA has 

determined that additional part marking 

of the washer, scissor branch, and mast 

ring of the corresponding nut side, and 

repetitive inspections of the additional 

part markings are necessary. This 

proposed AD would continue to require 

the actions in AD 2021–04–21; and also 

would require part marking of the 

washer, scissor branch, and mast ring of 

the corresponding nut side, and 

repetitive inspections of the additional 

part markings and repair if necessary; as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

proposed for incorporation by reference 

(IBR). 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 November 8, 

2021. 

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 2021–04–21, 

Amendment 39–21443 (86 FR 17278, 

April 2, 2021) (AD 2021–04–21), which 

applies to certain Airbus Helicopters 

Model EC120B helicopters. AD 2021– 

04–21 requires an inspection of the 

attachment bolts of the MR hub scissors 


lotter on DSK11XQN23PROD with PROPOSALS1
52860 Federal Register / Vol. 86, No. 182 / Thursday, September 23, 2021 / Proposed Rules 

assembly for discrepancies and repair if 

necessary; part marking of the 

attachment bolts of the MR hub scissors 

assembly; and repetitive inspections of 

the part marking of the attachment bolts, 

and repair if necessary. The FAA issued 

AD 2021–04–21 to address broken and 

bent attachment bolts of the MR hub 

scissors assembly, which could lead to 

detachment of a MR hub scissors 

attachment bolt, possibly resulting in 

complete loss of control of the 

helicopter. 

Actions Since AD 2021–04–21 Was 

Issued 

Since the FAA issued AD 2021–04– 

21, the FAA has determined that 

additional part marking of the washer, 

scissor branch, and mast ring of the 

corresponding nut side, and repetitive 

inspections of the additional part 

markings are necessary to detect 

rotation of the attachment bolts of the 

MR hub scissors assembly. 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2021–0046, dated February 12, 2021 

(EASA AD 2021–0046) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for all Airbus Helicopters Model 

EC120B helicopters. Although EASA 

AD 2021–0046 applies to all Model 

EC120B helicopters, this proposed AD 

would apply to helicopters with an 

affected part installed instead. 

This proposed AD was prompted by 

a report of broken and bent attachment 

bolts of the MR hub scissors assembly 

and a determination that additional part 

markings of the washer, scissor branch, 

and mast ring of the corresponding nut 

side, and repetitive inspections of the 

additional part markings are necessary. 

The FAA is proposing this AD to 

address broken and bent attachment 

bolts of the MR hub scissors assembly, 

which could lead to detachment of a MR 

hub scissors attachment bolt, possibly 

resulting in complete loss of control of 

the helicopter. See the MCAI for 

additional background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0046 specifies 

procedures for an inspection of the 

attachment bolts of the MR hub scissors 

assembly for discrepancies 

(discrepancies include corrosion, 

fretting, wear, cracking, bolt play, and 

bolt tightening torque) and repair if 

necessary; part marking of the washer, 

scissor branch, and mast ring of the 

attachment bolts and corresponding nut 

side of the MR hub scissors assembly; 

and repetitive inspections, after part 

marking, for discrepancies, and repair if 

necessary. The inspections of the 

attachment bolts of the MR hub 

assembly include checking the play and 

torque of the scissors attachment bolts 

and making sure that there are no hard 

spots in the scissors link hinge. 

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 

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 

after evaluating all the relevant 

information and determining the unsafe 

condition described previously is likely 

to exist or develop in other products of 

the same type design. 

Explanation of Retained Requirements 

Although this proposed AD does not 

explicitly restate the requirements of AD 

2021–04–21, this proposed AD would 

retain all of the requirements of AD 

2021–04–21. Those requirements are 

referenced in EASA AD 2021–0046, 

which, in turn, is referenced in 

paragraph (g) of this proposed AD. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

EASA AD 2021–0046 described 

previously, as incorporated by 

reference, except for any differences 

identified as exceptions in the 

regulatory text of this AD. 

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 to use this 

process. As a result, EASA AD 2021– 

0046 will be incorporated by reference 

in the FAA final rule. This proposed AD 

would, therefore, require compliance 

with EASA AD 2021–0046 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 

2021–0046 that is required for 

compliance with EASA AD 2021–0046 

will be available on the internet at 

https://www.regulations.gov by 

searching for and locating Docket No. 

FAA–2021–0829 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 89 helicopters 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 

Inspection for discrepancies (retained actions 

from AD 2021–04–21).

lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 86, No. 182 / Thursday, September 23, 2021 / Proposed Rules 52861 

The FAA estimates that it would take 

about 1 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 on U.S. operators to be 

$7,565, 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: 

ON-CONDITION COSTS

product 

Repair of the attachment bolts ..................................... 4 work-hours × $85 per hour = $340 ........................... $40 $380 

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 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 

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,

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 

expand the availability of RNAV routing 

in Alaska and improve the efficient flow 

of air traffic within the National 

Airspace System (NAS) by lessening the 

dependency on ground based 

navigation.
