Abstract
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.

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.
