Airworthiness Directives; Bell Textron 

Canada Limited Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2021–26–08, which applies to certain 

Bell Textron Canada Limited Model 

206, 206A, 206A–1, 206B, 206B–1, 

206L, 206L–1, 206L–3, and 206L–4 

helicopters. AD 2021–26–08 requires 

removing certain nuts from service; 

installing newly designed nuts; 

applying a specific torque, and a torque 

stripe to each newly installed nut; after 

the installation of each newly designed 

nut, inspecting the torque; and 

depending on the inspection results, 

either applying a torque stripe, or 

performing further inspections and 

removing certain parts from service. AD 

2021–26–08 also prohibits installing any 

affected nut on any tail rotor drive shaft 

(TRDS) disc pack (Thomas) coupling. 

Since the FAA issued AD 2021–26–089, 

the FAA determined certain torque 

values and part numbers (P/Ns) need to 

be revised. This proposed AD would 

require removing certain nuts from 

service; installing newly designed nuts; 

applying torque and a torque stripe; and 


jspears on DSK121TN23PROD with PROPOSALS1
39016 Federal Register / Vol. 87, No. 125 / Thursday, June 30, 2022 / Proposed Rules 

additional corrective actions if 

necessary. This proposed AD would 

also prohibit installing any affected nut 

on any TRDS Thomas coupling, as 

specified in a Transport Canada 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 August 15, 

2022. 

ADDRESSES: You may send comments,

Background 

The FAA issued AD 2021–26–08, 

Amendment 39–21867 (86 FR 72833, 

December 23, 2021) (AD 2021–26–08) 

for Bell Textron Canada Limited Model 

206, 206A, 206A–1, 206B, 206B–1, 

206L, 206L–1, 206L–3, and 206L–4 

helicopters, with nut P/N MS21042L4 or 

P/N MS21042L5 installed on the TRDS 

Thomas couplings. AD 2021–26–08 

requires removing certain nuts from 

service, installing newly designed nuts, 

and applying a specific torque and a 

torque stripe to each newly installed 

nut. AD 2021–26–08 also requires, after 

the installation of each newly designed 

nut, inspecting the torque and, 

depending on the inspection results, 

either applying a torque stripe or 

performing further inspections and 

removing certain parts from service. 

Finally, AD 2021–26–08 prohibits 

installing any affected nut on any TRDS 

Thomas coupling. The FAA issued AD 

2021–26–08 to prevent failure or loss of 

a nut on any TRDS Thomas coupling. 

AD 2021–26–08 was prompted by 

Transport Canada AD CF–2020–15, 

dated May 13, 2020 (Transport Canada 

AD CF–2020–15). Transport Canada, 

which is the aviation authority for 

Canada, issued Transport Canada AD 

CF–2020–15 to correct an unsafe 

condition for Bell Textron Canada 

Limited Model 206, 206A, 206A–1, 

206B, 206B–1, 206L, 206L–1, 206L–3, 

and 206L–4 helicopters, all serial 

numbers. Transport Canada AD CF– 

2020–15 specifies for certain model 

helicopters, newly designed nuts cannot 

be installed because Supplemental Type 

Certificate (STC) SH2750NM and 

Transport Canada STC SH99–202 install 

a pulley at the Thomas coupling 

location causing insufficient clearance. 

Transport Canada advises, for certain 

model helicopters with STC SH2750NM 

or Transport Canada STC SH99–202 

installed, different part-numbered nuts 

may be installed and are now required 

to be replaced with a new partnumbered nut that is not vulnerable to 

the unsafe condition.

Federal Register / Vol. 87, No. 125 / Thursday, June 30, 2022 / Proposed Rules 39017 

Actions Since AD 2021–26–08 Was 

Issued 

Since the FAA issued AD 2021–26– 

08, the FAA determined that certain P/ 

Ns and certain torque values in 

paragraph (g) of AD 2021–26–08 need to 

be revised. The FAA advises that the 

50–70 in lb torque values are only 

applicable to certain bolts and nuts, and 

a 150–180 in lb torque value is required 

for other bolts and nuts that are required 

to be installed by this proposed AD. The 

FAA also advises that certain partnumbered nuts that are required to be 

installed according to AD 2021–26–08 

need to be removed from service and 

replaced due to a certain pulley 

configuration. 

This proposed AD was prompted by 

reports of cracked or missing nuts 

installed on the TRDS Thomas 

couplings. The FAA is proposing this 

AD to prevent failure or loss of a nut on 

the TRDS Thomas couplings, which if 

not addressed could result in loss of the 

tail rotor and subsequent loss of control 

of the helicopter. See Transport Canada 

AD CF–2020–15 for additional 

background information. 

Related Service Information Under 1 

CFR Part 51 

Transport Canada AD CF–2020–15 

requires the replacement of certain partnumbered nuts with newly designed 

nuts at each TRDS Thomas coupling 

and prohibits installing any affected nut 

on any TRDS Thomas coupling. The 

replacement includes applying torque, 

and a torque stripe. 

The FAA reviewed Air Comm 

Corporation Service Bulletin SB 206EC– 

092619, Revision NC, dated September 

26, 2019, which also specifies 

procedures for replacing the affected 

nuts with the newly designed corrosionresistant nuts, but explains that affected 

helicopters equipped with Air Comm 

Corporation air conditioning systems 

installed under STC SH2750NM use the 

affected nut to attach a pulley onto the 

TRDS, which causes clearance issues for 

the nuts to be installed at the coupling. 

Therefore, this service bulletin specifies 

replacing the nut with a lower profile 

nut. 

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. 

Other Related Service Information 

The FAA also reviewed Bell Alert 

Service Bulletin (ASB) 206–19–136, 

dated August 27, 2019, for FAAcertificated Model 206, 206A-series, and 

206B-series helicopters, and non FAAcertificated Model TH–67 helicopters; 

and Bell ASB 206L–19–181, dated 

August 27, 2019, and Revision A, dated 

August 29, 2019, for Model 206L, 206L– 

1, 206L–3, and 206L–4 helicopters. This 

service information specifies procedures 

for replacing the affected nuts with the 

newly designed corrosion-resistant nuts. 

Revision A of Bell ASB 206L–19–181 

corrects a typographical error. 

Additionally, the FAA reviewed Bell 

Service Instruction BHT–206–SI–2052, 

Revision 1, dated October 14, 2010. This 

service information specifies procedures 

to upgrade Model 206L–1 and 206L–3 

helicopters to allow operations at an 

increased internal gross weight. 

Differences Between This Proposed AD 

and Transport Canada AD CF–2020–15 

Transport Canada AD CF–2020–15 

requires compliance with certain 

actions within 600 hours air time or 

within the next 24 months, whichever 

occurs first, whereas this proposed AD 

would require compliance within 600 

hours time-in-service only. Service 

information referenced in Transport 

Canada AD CF–2020–15 specifies if any 

P/N MS21042L4 nuts are found loose or 

damaged, reporting the location and 

providing the information to Bell, 

whereas this proposed AD would 

require if any P/N MS21042L4 nuts are 

found loose or damaged, inspecting 

each TRDS Thomas coupling, including 

each bolt, nut, and washer, for any 

elongated holes, fretting on the 

fasteners, and damaged fasteners, and 

depending on the results of the 

inspection, removing from service each 

affected part and replacing it with an 

airworthy part. 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of Canada and 

are approved for operation in the United 

States. Pursuant to the FAA’s bilateral 

agreement with Canada, Transport 

Canada, its technical representative, has 

notified the FAA of the unsafe condition 

described in its AD. The FAA is 

proposing this AD after evaluating all 

known relevant information and 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other helicopters of these 

same type designs. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

Transport Canada AD CF–2020–15, 

described previously, as incorporated by 

reference, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD and 

except as discussed under ‘‘Differences 

Between this Proposed AD and 

Transport Canada AD CF–2020–15.’’ 

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 Transport Canada AD CF– 

2020–15 by reference in the FAA final 

rule. This proposed AD would, 

therefore, require compliance with 

Transport Canada AD CF–2020–15 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 Transport Canada 

AD CF–2020–15 does not mean that 

operators need comply only with that 

section. For example, where the AD 

requirement refers to ‘‘corrective 

actions,’’ compliance with this AD 

requirement is not limited to the section 

titled ‘‘Corrective Actions’’ in Transport 

Canada AD CF–2020–15. Service 

information referenced in Transport 

Canada AD CF–2020–15 for compliance 

will be available at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0807 after the FAA final rule is 

published. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 1,359 

helicopters of U.S. Registry. Labor rates 

are estimated at $85 per work-hour. 

Based on these numbers, the FAA 

estimates the following costs to comply 

with this proposed AD. 

Replacing each affected nut with the 

newly designed nut and applying torque 

and a torque stripe would take about 4 

work-hours, and parts would cost about 

$75 for an estimated cost of $415 per 

nut replacement and $563,985 per nut 

replacement for the U.S. fleet. 

In addition, the costs of the actions 

that are part of the required replacement 

are as follows: 

If required due to loose or damaged 

nuts found, inspecting each TRDS 

Thomas coupling, and each bolt, nut, 

and washer for elongated holes and 

fretting on the fasteners would take 

about 0.5 work-hour for an estimated 

cost of $43 per inspection. 


jspears on DSK121TN23PROD with PROPOSALS1
39018 Federal Register / Vol. 87, No. 125 / Thursday, June 30, 2022 / Proposed Rules 

If required, replacing each TRDS 

Thomas coupling would take about 4 

work-hours, and parts would cost about 

$4,000 for an estimated cost of $4,340 

per TRDS Thomas coupling 

replacement. 

If required, replacing a bolt or washer 

would take a minimal amount of time 

and parts would cost a nominal amount. 

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,

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Airbus Helicopters Model AS355E, 

AS355F, AS355F1, AS355F2, AS355N, 

and AS355NP helicopters. This 

proposed AD was prompted by the 

identification of certain parts needing 

maintenance actions, including life 

limits and maintenance tasks. This 

proposed AD would require 

incorporating into maintenance records 

requirements (airworthiness 

limitations), as specified in a European
