Federal Register / Vol. 86, No. 175 / Tuesday, September 14, 2021 / Proposed Rules 51035 

originated by an aviation authority of another 

country to identify and address an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as a nonconfirming dump switch ejecting from its 

slot. The FAA is issuing this AD to prevent 

dump switches ejecting from their slots, 

which, in case of smoke/fumes in the cabin, 

could prevent evacuation of the smoke/ 

fumes. The unsafe condition, if not 

addressed, could result in excessive flight 

crew workload and injury to airplane 

occupants. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

Within 12 months after the effective date 

of this AD, inspect each dump switch part 

number (P/N) 7388475012 to determine if a 

seal is installed, as depicted in Figure 3 of 

Daher Aerospace Service Bulletin SB 70– 

271–21, Revision 1, dated November 2019. 

(1) If a seal is installed, no further action 

is required by this paragraph. 

(2) If a seal is not installed, within 12 

months after the effective date of this AD, 

modify the dump switch in accordance with 

steps 2) through 5) of the Description of 

Accomplishment Instructions in Daher 

Aerospace Service Bulletin SB 70–271–21, 

Revision 1, dated November 2019. 

(h) Parts Installation Provision 

As of the effective date of this AD, do not 

install a dump switch P/N 7388475012 on 

any airplane unless the switch has been 

modified as described in Daher Aerospace 

Service Bulletin SB 70–271–21, Revision 1, 

dated November 2019. Removal of a dump 

switch from an airplane and re-installation of 

that dump switch on the same airplane 

within the same maintenance visit is not an 

installation for purposes of this paragraph. 

(i) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, General Aviation & 

Rotorcraft Section, International Validation 

Branch, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19. In 

accordance with 14 CFR 39.19, send your 

request to your principal inspector or local 

Flight Standards District Office, as 

appropriate. If sending information directly 

to the manager of the International Validation 

Branch, send it to the attention of the person 

identified in paragraph (j)(1) of this AD or 

email: 9-AVS-AIR-730-AMOC@faa.gov. 

(2) Before using any approved AMOC, 

notify your appropriate principal inspector, 

or lacking a principal inspector, the manager 

of the local flight standards district office/

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2021–06–06, which applies to certain 

Bell Textron Canada Limited Model 505 

helicopters. AD 2021–06–06 requires 

repetitive fluorescent penetrant 

inspections (FPIs) of the pilot collective 

stick and grip assembly and revising the 

existing Rotorcraft Flight Manual (RFM) 

for your helicopter. Since the FAA 

issued AD 2021–06–06, the pilot 

collective stick and grip assembly has 

been redesigned. This proposed AD 

would retain certain requirements of AD 

2021–06–06, require modifying your 

helicopter to include the improved pilot 

collective stick tube and would add a 

terminating action for the repetitive 

FPIs. This proposed AD would also 

prohibit installing any pilot collective 

stick and grip assembly unless certain 

requirements of this proposed AD were 

met. 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 October 29, 

2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Background 

The FAA issued AD 2021–06–06, 

Amendment 39–21473 (86 FR 14366, 

March 16, 2021) (AD 2021–06–06), for 

Bell Textron Canada Limited Model 505 

helicopters, serial number (S/N) 65011 

and subsequent. AD 2021–06–06 

requires, before further flight, revising 

the Limitations section of the existing 

RFM for your helicopter to prohibit 

single pilot operations from the right 

crew seat, require the pilot in command 

to occupy the left crew seat for dual 

pilot operations, and depending on 

configuration, prohibit the use of SPLITCOM mode. AD 2021–06–06 also 

requires, before further flight and 

thereafter at intervals not to exceed 25 

hours time-in-service (TIS), removing 

and cleaning the pilot collective stick 

and grip assembly and performing an 

FPI for a crack as specified in the 

manufacturers service information. AD 

2021–06–06 also requires removing any 

cracked pilot collective stick and grip 

assembly from service before further 

flight, and within 10 days after the 

discovery of any crack, reporting certain 

information to Bell Product Support 

Engineering. AD 2021–06–06 also 

prohibits installing any pilot collective 

stick and grip assembly on any 

helicopter unless it has successfully 

passed the FPI requirements of AD 

2021–06–06. Lastly, AD 2021–06–06 

prohibits relief under any Master 

Minimum Equipment List or Minimum 

Equipment List for the Audio Panel 

when the aircraft is operated with a 

single pilot. 

AD 2021–06–06 was prompted by 

Canadian Emergency AD CF–2021– 

05R2, dated March 4, 2021 (Transport 

Canada Emergency AD CF–2021–05R2), 

issued by Transport Canada, which is 

the aviation authority for Canada, to 

correct an unsafe condition for Bell 

Textron Canada Limited Model 505 

helicopters, S/Ns 65011 and subsequent. 

Transport Canada advised that FPIs 

findings showed that cracking of the 

pilot collective stick and grip assembly 

could occur at very low flight hours. 

Transport Canada also specified that 

Bell Textron Canada Limited revised its 

service information to introduce a 

temporary revision to the RFM 

prohibiting single pilot operations from 

the right crew seat. This condition, if 

not addressed, could result in failure of 

the pilot collective stick and grip 

assembly and subsequent loss of control 

of the helicopter. 

Accordingly, Transport Canada 

Emergency AD CF–2021–05R2 

prohibited single pilot operations from 

the right crew seat in accordance with 

the manufacturers service information. 

Transport Canada considered its AD an 

interim action and stated that further 

AD action may follow. 

Actions Since AD 2021–06–06 Was 

Issued 

Since the FAA issued AD 2021–06– 

06, Transport Canada issued AD CF– 

2021–05R3, dated March 19, 2021 

(Transport Canada AD CF–2021–05R3), 

which supersedes Transport Canada 

Emergency AD CF–2021–05R2. 

Transport Canada advises that since 

Transport Canada Emergency AD CF– 

2021–05R2 was issued, the pilot 

collective stick and grip assembly has 

been redesigned to address the root 

cause of the cracking. Accordingly, 

Transport Canada AD CF–2021–05–R3 

retains the requirements of Transport 

Canada Emergency AD CF–2021–05R2 

and requires installing the newly 

designed pilot collective stick and grip 

assembly, which is a terminating action 

for the requirements of Transport 

Canada Emergency AD CF–2021–05R2. 

Transport Canada AD CF–2021–05R3 

also revises the applicability to include 

only helicopters that have not 

incorporated the redesigned pilot 

collective stick and grip assembly 

during production. 

Finally, the FAA received one 

comment on AD 2021–06–06 from one 

commenter. Advanced Helicopter 

Services requested additional 

information about AD 2021–06–06, 

specifically whether performing certain 

actions specified in Bell Alert Service 

Bulletin 505–21–20, Revision C, dated 

March 11, 2021 (ASB 505–21–20 Rev C) 

would be considered a terminating 

action for the inspections required by 

AD 2021–06–06. 

The FAA has determined that it is 

necessary to supersede AD 2021–06–06. 

The proposed required actions, 

including required actions performed in 

accordance with portions of ASB 505– 

21–20 Rev C, would include a 

terminating action for the repetitive FPI 

inspections. 

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 the same 

type design. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed ASB 505–21–20 

Rev C, which provides instructions for 

an initial and recurring FPIs for cracks 

in the pilot collective stick and grip 

assembly part number (P/N) M207– 

20M478–041/–043/–047 on Bell Textron 

Canada Limited Model 505 helicopters, 

serial numbers 65011 through 65347. 

ASB 505–21–20 Rev C also specifies 

inserting a temporary revision into the 

RFM that prohibits single pilot 

operations from the right crew seat until 

further notice, and specifies that if the 

right crew seat pilot collective stick and 

grip assembly was previously confirmed 

serviceable following an FPI then the 25 

flight hour recurring FPI of the right 

crew seat pilot collective stick and grip 

assembly is no longer required provided 

that the helicopter is only operated 


tkelley on DSK125TN23PROD with PROPOSALS
Federal Register / Vol. 86, No. 175 / Tuesday, September 14, 2021 / Proposed Rules 51037 

single pilot in command (PIC) from the 

left crew seat. 

The FAA also reviewed Bell 505 RFM 

TR for Pilot Collective (ASB 505–21– 

20), BHT–505–FM–1, Temporary 

Revision (TR–6) (BHT–505–FM–1, TR– 

6) and Bell 505 RFM TR for Pilot 

Collective (ASB 505–21–20), BHT–505– 

FM–2, Temporary Revision (TR–1), each 

dated March 3, 2021. These temporary 

revisions specify changes to Section 1 of 

the RFM Limitations Section that the 

minimum flight crew consists of one 

pilot that shall operate from the left 

crew seat and that dual operation is 

approved provide that the PIC occupies 

the left crew seat. BHT–505–FM–1, TR– 

6 also prohibits use of SPLIT–COM 

mode. 

This service information 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. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would retain 

certain requirements from AD 2021–06– 

06. This proposed AD would require, 

before further flight, revising Section 1, 

the Limitations section of the existing 

RFM for your helicopter to prohibit 

single pilot operations from the right 

crew seat, require the PIC to occupy the 

left crew seat for dual pilot operations, 

and depending on configuration, 

prohibit the use of SPLIT-COM mode. 

This proposed AD would also require, 

before further flight after the effective 

date of this AD, and thereafter at 

intervals not to exceed 25 hours TIS, 

removing the pilot collective stick and 

grip assembly and performing an FPI for 

a crack and depending on the inspection 

results, removing a certain part from 

service. This proposed AD would also 

require within 12 months after the 

effective date of this AD, removing a 

certain part-numbered pilot collective 

stick tube from service and installing an 

improved pilot collective stick tube in 

accordance with the manufacturers 

service information and thereafter, 

removing a certain part-numbered pilot 

collective stick tube from service before 

it accumulates 300 total hours TIS. 

Additionally, this proposed AD would 

consider certain proposed actions to be 

a terminating action for other proposed 

actions. This proposed AD would also 

prohibit installing any pilot collective 

stick and grip assembly unless certain 

proposed actions are accomplished. 

This proposed AD would require 

revising the Limitations section of the 

existing RFM for your helicopter. An 

owner/operator (pilot) may incorporate 

the RFM revisions, and the owner/ 

operator must enter compliance with 

the applicable paragraphs of the AD into 

the aircraft records in accordance with 

14 CFR 43.9(a)(1) through (4) and 14 

CFR 91.417(a)(2)(v). This is an 

exception to the FAA’s standard 

maintenance regulations. 

Differences Between This Proposed AD 

and the Transport Canada AD 

This proposed AD would prohibit 

relief under any Master Minimum 

Equipment List or Minimum Equipment 

List for the Audio Panel when the 

aircraft is operated with a single pilot, 

whereas Transport Canada AD CF– 

2021–05R3 does not. Transport Canada 

AD CF–2021–05R3 requires the 

repetitive FPIs if the aircraft is not flown 

solely from the left crew seat whereas 

this proposed AD requires FPIs 

regardless. 

Transport Canada AD CF–2021–05R3 

requires operators to ‘‘advise all flight 

crews’’ of changes to the RFM, and 

thereafter to ‘‘operate the helicopter 

accordingly.’’ However, this AD would 

not specifically require those actions. 14 

CFR 91.9 requires that no person may 

operate a civil aircraft without 

complying with the operating 

limitations specified in the RFM. 

Therefore, including a requirement in 

this proposed AD to operate the 

helicopter according to the revised RFM 

would be redundant and unnecessary. 

Further, compliance with such a 

requirement in an AD would be 

impracticable to demonstrate or track on 

an ongoing basis; therefore, a 

requirement to operate the helicopter in 

such a manner would be unenforceable. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 98 

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. 

Revising the existing RFM for your 

helicopter would take about 0.5 workhour for an estimated cost of $43 per 

helicopter. 

Removing, cleaning, and performing 

an FPI of the pilot collective stick and 

grip assembly would take about 3 workhours for an estimated cost of $255 per 

helicopter and $24,990 for the U.S. fleet 

per inspection cycle. 

Installing an improved pilot collective 

stick tube would take about 5 workhours and parts would cost about $1,256 

for an estimated cost of $1,681 per 

helicopter. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some of the 

costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

operators. 

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, 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.

addressed, could result in failure of the pilot 

collective stick and grip assembly and 

subsequent loss of control of the helicopter. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

(1) Before further flight after the effective 

date of this AD, revise the Limitations section 

of the existing Rotorcraft Flight Manual 

(RFM) for your helicopter by inserting Bell 

505 RFM Temporary Revision (TR) for Pilot 

Collective (ASB 505–21–20), BHT–505–FM– 

1, Temporary Revision (TR–6) or Bell 505 

RFM TR for Pilot Collective (ASB 505–21– 

20), BHT–505–FM–2, Temporary Revision 

(TR–1), each dated March 3, 2021, as 

applicable to your helicopter. Using a 

different document with information 

identical to the information for the ‘‘Flight 

Crew’’ and ‘‘Configuration,’’ as applicable to 

your helicopter, in the RFM TR specified in 

this paragraph for your helicopter is 

acceptable for compliance with the 

requirements of this paragraph. This action 

may be performed by the owner/operator 

(pilot) holding at least a private pilot 

certificate and must be entered into the 

aircraft records showing compliance with 

this AD in accordance with § 43.9(a)(1) 

through (4) and § 91.417(a)(2)(v). The record 

must be maintained as required by § 91.417, 

§ 121.380, or § 135.439. 

(2) Before further flight after the effective 

date of this AD, and thereafter at intervals not 

to exceed 25 hours time-in-service (TIS): 

(i) Remove the pilot collective stick and 

grip assembly from the jackshaft assembly 

and clean the areas specified in Figure 2 of 

Bell Alert Service Bulletin 505–21–20, 

Revision C, dated March 11, 2021 (ASB 505– 

21–20 Rev C) with a clean cloth C–516C or 

equivalent moistened with dry cleaning 

solvent C–304 or equivalent. 

(ii) Perform a fluorescent penetrant
