ACTION: Final rule. AGENCY: The FAA is superseding Airworthiness Directive (AD) 2021–06– 06, which applied to certain Bell Textron Canada Limited Model 505 helicopters. AD 2021–06–06 required 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 AD retains certain requirements of AD 2021–06–06, requires modifying your helicopter to include the improved pilot collective stick tube and adds a terminating action for the repetitive FPIs. This AD also prohibits installing any pilot collective stick and grip assembly unless certain requirements of this AD are met. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective April 4, 2022. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 4, 2022. The Director of the Federal Register approved the incorporation by reference of certain other publications listed in this AD as of March 31, 2021 (86 FR 14366, March 16, 2021).

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede 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. The NPRM published in the Federal Register on September 14, 2021 (86 FR 51035). In the NPRM, the FAA proposed to retain some of the requirements of AD 2021–06–06, including, 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 pilot in command (PIC) to occupy the left crew seat for dual pilot operations, and depending on configuration, prohibit the use of SPLIT–COM mode. The NPRM also proposed to require, before further flight, and thereafter at intervals E:\FR\FM\28FER1.SGM 28FER1 khammond on DSKJM1Z7X2PROD with RULES Federal Register / Vol. 87, No. 39 / Monday, February 28, 2022 / Rules and Regulations not to exceed 25 hours time-in-service (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. The NPRM proposed to require, within 12 months, 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, the NPRM would consider certain proposed actions to be a terminating action for other actions proposed in the NPRM. The NPRM also proposed to prohibit installing any pilot collective stick and grip assembly unless certain proposed actions were accomplished. Finally, the NPRM proposed to require revising the Limitations section of the existing RFM for your helicopter; the 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. The NPRM was prompted by Transport Canada AD CF–2021–05R3, dated March 19, 2021 (Transport Canada AD CF–2021–05R3), 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 through 65347. Transport Canada advises that the pilot collective stick and grip assembly has been redesigned to address the root cause of the cracking. Accordingly, Transport Canada AD CF–2021–05R3 retains the requirements of Transport Canada Emergency AD CF–2021–05R2, dated March 4, 2021 (Transport Canada Emergency AD CF–2021–05R2), which prompted AD 2021–06–06, 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. Therefore, the FAA determined that it is necessary to supersede AD 2021–06– 06 and the required actions as proposed VerDate Sep<11>2014 16:12 Feb 25, 2022 Jkt 256001 10951 in the NPRM include a terminating action for the repetitive FPI inspections. Request for Changes to the Credit for Previous Actions Discussion of Final Airworthiness Directive Bell requested that the FAA allow credit for the required actions through an approved AMOC and service information. Bell stated that the FAA approved an AMOC to AD 2021–06–06 on March 26, 2021, which allowed operators to implement a terminating action based on the instructions contained in Bell Alert Service Bulletin 505–21–20, Revision C, dated March 11, 2021 (ASB 505–21–20 Rev C). Bell requested that the approved AMOC and ASB 505–21–20 Rev C be included in the Credit for Previous Actions paragraph. The FAA agrees with the request to allow credit; however, the FAA disagrees with putting this information in the Credit for Previous Actions paragraph. The FAA agrees that the previously approved AMOC to AD 2021–06–06 continues to be valid to address the unsafe condition. Accordingly, the FAA has revised the AMOC paragraph in this final rule by adding paragraph (j)(3), which states ‘‘AMOCs approved previously for AD 2021–06–06 are approved as AMOCs for the corresponding requirements in paragraph (g) of this AD.’’ Additionally, the purpose of the Credit for Previous Actions paragraph is to allow credit for required actions accomplished previously in accordance with previous revision(s) of service information. Since ASB 505–21–20 Rev C is required to accomplish certain actions in paragraph (g) of this AD, previous accomplishment of those actions in ASB 505–21–20 Rev C could be considered accomplished by paragraph (f) of this AD. Comments The FAA received comments from one commenter; Bell. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request for Changes to the Required Actions Bell requested that the FAA revise the life limit of pilot collective stick tube part number (P/N) M207–20M301–043. Bell stated that 300 total hours TIS was only an interim life limit and after the completion of fatigue testing, the life limit of 6,250 total hours TIS has been approved by Transport Canada. Specifically, Bell requested that the FAA change the required action to, ‘‘Replace the pilot collective stick tube P/N M207–20M301–043 at or before reaching its Life Limit as defined in Table 1 of the Maintenance Planning Information (MPI) Chapter 4 Airworthiness Limitations Schedule (ALS), BHT–505–MPI Chapter 4 Issue 09, dated 12 March 2021, or later revisions of the ALS approved by Transport Canada.’’ The FAA partially agrees. The FAA disagrees with changing the action from removing the pilot collective stick tube from service to ‘‘replace the pilot collective stick tube’’ because this is a life limit and, once the life limit is reached, the part must be removed from service and never installed on any aircraft again. Additionally, due to eligibility requirements in 1 CFR part 51, the FAA cannot mandate use of ‘‘later revisions’’ of service information directly in an AD. However, the FAA agrees with the life limit threshold increasing from 300 total hours TIS to 6,250 total hours TIS and, accordingly has changed that life limit in this final rule. Bell requested that the FAA revise paragraph (g)(6) of the Required Actions that states relief under any Master Minimum Equipment List or Minimum Equipment List for the Audio Panel is prohibited when the aircraft is operated with a single pilot. Bell stated that this restriction is only applicable when operated from the left hand seat, and the aircraft must be flown from the right hand seat when SPLIT–COM mode is enabled. Bell further stated this is consistent with the limitations of the flight manual. The FAA agrees and has revised the required actions in this final rule accordingly. PO 00000 Frm 00027 Fmt 4700 Sfmt 4700 Other Changes Between the NPRM and This Final Rule In this final rule, the FAA has changed the effective date of paragraph (g)(1) from ‘‘after the effective date of this AD’’ to ‘‘from March 31, 2021 (the effective date of AD 2021–06–06),’’ because this paragraph carries-over identical required actions from paragraph (g)(1) of AD 2021–06–06. Conclusion These helicopter 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 reviewed the relevant data, considered the comments received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is E:\FR\FM\28FER1.SGM 28FER1 khammond on DSKJM1Z7X2PROD with RULES 10952 Federal Register / Vol. 87, No. 39 / Monday, February 28, 2022 / Rules and Regulations issuing this AD to address the unsafe condition on these helicopters. Except for minor editorial changes, and any other changes described previously, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. specifies a one-time inspection for cracks of the pilot collective stick and grip assembly. ASB 505–21–20 Rev A removes the visual inspection and adds a repetitive FPI. ASB 505–21–20 Rev B adds the RFM temporary revision and clarifies the compliance time of the repetitive FPI. Related Service Information Under 1 CFR Part 51 The FAA reviewed ASB 505–21–20 Rev C, which provides instructions for an initial and repetitive FPIs for cracks in the pilot collective stick and grip assembly 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 (TR) 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 repetitive FPI of the right crew seat pilot collective stick and grip assembly is no longer required provided that the helicopter is only operated single PIC from the left crew seat. ASB 505–21–20 Rev C also introduces procedures to install an improved pilot collective stick tube assembly, along with its initial life limit, and which is also terminating action for the repetitive FPIs and temporary RFM revision. 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 provided 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. Differences Between This AD and Transport Canada AD CF–2021–05R3 This AD 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 from the left seat, 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 AD requires repetitive 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 does 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 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. This AD prohibits installing any pilot collective stick and grip assembly on any helicopter unless the actions required by paragraphs (g)(2) and (3) of this AD have been accomplished, whereas Transport Canada AD CF– 2021–05R3 does not. Other Related Service Information The FAA reviewed Bell ASB 505–21– 20, dated February 20, 2021 (ASB 505– 21–20), Bell ASB 505–21–20, Revision A, dated February 26, 2021 (ASB 505– 21–20 Rev A), and Bell ASB 505–21–20, Revision B, dated March 3, 2021 (ASB 505–21–20 Rev B). ASB 505–21–20 VerDate Sep<11>2014 16:12 Feb 25, 2022 Jkt 256001 Costs of Compliance The FAA estimates that this AD affects 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 AD. Revising the existing RFM for your helicopter takes about 0.5 work-hour for an estimated cost of $43 per helicopter and up to $4,214 for the U.S. fleet. Removing, cleaning, and performing an FPI of the pilot collective stick and grip assembly takes about 3 work-hours for an estimated cost of $255 per helicopter and up to $24,990 for the U.S. fleet per inspection cycle. Installing an improved pilot collective stick tube takes about 5 work-hours and PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 parts cost about $1,256 for an estimated cost of $1,681 per helicopter and up to $164,738 for the U.S. fleet per replacement cycle. The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this 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 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. For the reasons discussed above, I certify that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) Will 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, Safety. The Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: E:\FR\FM\28FER1.SGM 28FER1 Federal Register / Vol. 87, No. 39 / Monday, February 28, 2022 / Rules and Regulations PART 39—AIRWORTHINESS DIRECTIVES 1.

SUPPLEMENTARY INFORMATION: Background The TCCA, which is the aviation authority for Canada, has issued TCCA AD CF–2021–25, dated July 22, 2021 (TCCA AD CF–2021–25) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus Canada Limited Partnership Model BD–500– 1A10 and BD–500–1A11 airplanes. PO 00000 Frm 00030 Fmt 4700 Sfmt 4700 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 Canada Limited Partnership Model BD–500–1A10 and BD–500–1A11 airplanes. The NPRM published in the Federal Register on December 17, 2021 (86 FR 71589). The NPRM was prompted by a report that some tie-rod assemblies may have been overtightened during the installation of interior monuments (such as galleys, lavatories, and forward stowage or wardrobes). The NPRM proposed to require adjusting the tie-rod assemblies, as specified in TCCA AD CF–2021–25. The FAA is issuing this AD to address overtightened (pre-loaded) tie-rods that induce unwanted stress in a monument and may cause the monument to become unconstrained in an emergency landing, potentially blocking exits or injuring occupants. See the MCAI for additional background information. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. Conclusion The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Except for minor editorial changes, this AD is adopted as proposed in the NPRM.

Airworthiness Directives; Bell Textron Canada Limited Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-06-
06, which applied to certain Bell Textron Canada Limited Model 505 
helicopters. AD 2021-06-06 required 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 AD retains certain 
requirements of AD 2021-06-06, requires modifying your helicopter to 
include the improved pilot collective stick tube and adds a terminating 
action for the repetitive FPIs. This AD also prohibits installing any 
pilot collective stick and grip assembly unless certain requirements of 
this AD are met. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective April 4, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 4,

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede 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. The 
NPRM published in the Federal Register on September 14, 2021 (86 FR 
51035). In the NPRM, the FAA proposed to retain some of the 
requirements of AD 2021-06-06, including, 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 pilot in command (PIC) to occupy the left crew seat 
for dual pilot operations, and depending on configuration, prohibit the 
use of SPLIT-COM mode. The NPRM also proposed to require, before 
further flight, and thereafter at intervals

[[Page 10951]]

not to exceed 25 hours time-in-service (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. The NPRM proposed to require, within 12 months, 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, the NPRM would consider certain proposed actions to 
be a terminating action for other actions proposed in the NPRM. The 
NPRM also proposed to prohibit installing any pilot collective stick 
and grip assembly unless certain proposed actions were accomplished. 
Finally, the NPRM proposed to require revising the Limitations section 
of the existing RFM for your helicopter; the 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.
    The NPRM was prompted by Transport Canada AD CF-2021-05R3, dated 
March 19, 2021 (Transport Canada AD CF-2021-05R3), 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 through 65347. Transport Canada advises that the pilot 
collective stick and grip assembly has been redesigned to address the 
root cause of the cracking. Accordingly, Transport Canada AD CF-2021-
05R3 retains the requirements of Transport Canada Emergency AD CF-2021-
05R2, dated March 4, 2021 (Transport Canada Emergency AD CF-2021-05R2), 
which prompted AD 2021-06-06, 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.
    Therefore, the FAA determined that it is necessary to supersede AD 
2021-06-06 and the required actions as proposed in the NPRM include a 
terminating action for the repetitive FPI inspections.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from one commenter; Bell. The following 
presents the comments received on the NPRM and the FAA's response to 
each comment.

Request for Changes to the Required Actions

    Bell requested that the FAA revise the life limit of pilot 
collective stick tube part number (P/N) M207-20M301-043. Bell stated 
that 300 total hours TIS was only an interim life limit and after the 
completion of fatigue testing, the life limit of 6,250 total hours TIS 
has been approved by Transport Canada. Specifically, Bell requested 
that the FAA change the required action to, ``Replace the pilot 
collective stick tube P/N M207-20M301-043 at or before reaching its 
Life Limit as defined in Table 1 of the Maintenance Planning 
Information (MPI) Chapter 4 Airworthiness Limitations Schedule (ALS), 
BHT-505-MPI Chapter 4 Issue 09, dated 12 March 2021, or later revisions 
of the ALS approved by Transport Canada.''
    The FAA partially agrees. The FAA disagrees with changing the 
action from removing the pilot collective stick tube from service to 
``replace the pilot collective stick tube'' because this is a life 
limit and, once the life limit is reached, the part must be removed 
from service and never installed on any aircraft again. Additionally, 
due to eligibility requirements in 1 CFR part 51, the FAA cannot 
mandate use of ``later revisions'' of service information directly in 
an AD. However, the FAA agrees with the life limit threshold increasing 
from 300 total hours TIS to 6,250 total hours TIS and, accordingly has 
changed that life limit in this final rule.
    Bell requested that the FAA revise paragraph (g)(6) of the Required 
Actions that states relief under any Master Minimum Equipment List or 
Minimum Equipment List for the Audio Panel is prohibited when the 
aircraft is operated with a single pilot. Bell stated that this 
restriction is only applicable when operated from the left hand seat, 
and the aircraft must be flown from the right hand seat when SPLIT-COM 
mode is enabled. Bell further stated this is consistent with the 
limitations of the flight manual.
    The FAA agrees and has revised the required actions in this final 
rule accordingly.

Request for Changes to the Credit for Previous Actions

    Bell requested that the FAA allow credit for the required actions 
through an approved AMOC and service information. Bell stated that the 
FAA approved an AMOC to AD 2021-06-06 on March 26, 2021, which allowed 
operators to implement a terminating action based on the instructions 
contained in Bell Alert Service Bulletin 505-21-20, Revision C, dated 
March 11, 2021 (ASB 505-21-20 Rev C). Bell requested that the approved 
AMOC and ASB 505-21-20 Rev C be included in the Credit for Previous 
Actions paragraph.
    The FAA agrees with the request to allow credit; however, the FAA 
disagrees with putting this information in the Credit for Previous 
Actions paragraph. The FAA agrees that the previously approved AMOC to 
AD 2021-06-06 continues to be valid to address the unsafe condition. 
Accordingly, the FAA has revised the AMOC paragraph in this final rule 
by adding paragraph (j)(3), which states ``AMOCs approved previously 
for AD 2021-06-06 are approved as AMOCs for the corresponding 
requirements in paragraph (g) of this AD.'' Additionally, the purpose 
of the Credit for Previous Actions paragraph is to allow credit for 
required actions accomplished previously in accordance with previous 
revision(s) of service information. Since ASB 505-21-20 Rev C is 
required to accomplish certain actions in paragraph (g) of this AD, 
previous accomplishment of those actions in ASB 505-21-20 Rev C could 
be considered accomplished by paragraph (f) of this AD.

Other Changes Between the NPRM and This Final Rule

    In this final rule, the FAA has changed the effective date of 
paragraph (g)(1) from ``after the effective date of this AD'' to ``from 
March 31, 2021 (the effective date of AD 2021-06-06),'' because this 
paragraph carries-over identical required actions from paragraph (g)(1) 
of AD 2021-06-06.

Conclusion

    These helicopter 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 reviewed the relevant data, considered the 
comments received, and determined that air safety requires adopting 
this AD as proposed. Accordingly, the FAA is

[[Page 10952]]

issuing this AD to address the unsafe condition on these helicopters. 
Except for minor editorial changes, and any other changes described 
previously, this AD is adopted as proposed in the NPRM. None of the 
changes will increase the economic burden on any operator.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed ASB 505-21-20 Rev C, which provides instructions 
for an initial and repetitive FPIs for cracks in the pilot collective 
stick and grip assembly 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 (TR) 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 
repetitive FPI of the right crew seat pilot collective stick and grip 
assembly is no longer required provided that the helicopter is only 
operated single PIC from the left crew seat. ASB 505-21-20 Rev C also 
introduces procedures to install an improved pilot collective stick 
tube assembly, along with its initial life limit, and which is also 
terminating action for the repetitive FPIs and temporary RFM revision.
    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 
provided 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.

Other Related Service Information

    The FAA reviewed Bell ASB 505-21-20, dated February 20, 2021 (ASB 
505-21-20), Bell ASB 505-21-20, Revision A, dated February 26, 2021 
(ASB 505-21-20 Rev A), and Bell ASB 505-21-20, Revision B, dated March 
3, 2021 (ASB 505-21-20 Rev B). ASB 505-21-20 specifies a one-time 
inspection for cracks of the pilot collective stick and grip assembly. 
ASB 505-21-20 Rev A removes the visual inspection and adds a repetitive 
FPI. ASB 505-21-20 Rev B adds the RFM temporary revision and clarifies 
the compliance time of the repetitive FPI.

Differences Between This AD and Transport Canada AD CF-2021-05R3

    This AD 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 from the left seat, 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 AD requires repetitive 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 does 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 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.
    This AD prohibits installing any pilot collective stick and grip 
assembly on any helicopter unless the actions required by paragraphs 
(g)(2) and (3) of this AD have been accomplished, whereas Transport 
Canada AD CF-2021-05R3 does not.

Costs of Compliance

    The FAA estimates that this AD affects 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 AD.
    Revising the existing RFM for your helicopter takes about 0.5 work-
hour for an estimated cost of $43 per helicopter and up to $4,214 for 
the U.S. fleet.
    Removing, cleaning, and performing an FPI of the pilot collective 
stick and grip assembly takes about 3 work-hours for an estimated cost 
of $255 per helicopter and up to $24,990 for the U.S. fleet per 
inspection cycle.
    Installing an improved pilot collective stick tube takes about 5 
work-hours and parts cost about $1,256 for an estimated cost of $1,681 
per helicopter and up to $164,738 for the U.S. fleet per replacement 
cycle.
    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this 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

    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.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
