Airworthiness Directives; Bell Textron Canada Limited (Type
Certificate Previously Held by Bell Helicopter Textron Canada Limited)
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Bell Helicopter Textron Canada Limited (now Bell Textron Canada
Limited) Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4
helicopters. This AD was prompted by a report that a certain tail rotor
disc assembly, sold as an alternate part, does not conform to the
approved configuration. This AD requires determining if an affected
part is installed (by doing a maintenance records check or inspection),
and if an affected part is found, replacement with a non-affected part.
The FAA is issuing this AD to address the unsafe condition on these
products.
DATES: This AD is effective August 27, 2021.
The Director of the Federal Register approved the incorporation by
reference of certain documents listed in this AD as of August 27, 2021.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a supplemental notice of proposed rulemaking (SNPRM)
to amend 14 CFR part 39 by adding an AD that would apply to certain
Bell Textron Canada Limited Model 206A, 206B, 206L, 206L-1, 206L-3, and
206L-4 helicopters. The SNPRM published in the Federal Register on May
7, 2021 (86 FR 24560). The SNPRM proposed to require determining if an
affected part is installed (by doing a maintenance records check or
inspection), and if an affected part is found, replacement with a non-
affected part. The SNPRM also revised the format, rearranged certain
paragraphs, converted a certain table to paragraph format, and removed
certain language. The SNPRM was prompted by a significant amount of
time elapsing since the notice of proposed rulemaking (NPRM) (75 FR
52914, August 30, 2010) was issued, requiring the FAA to reopen the
comment period to allow the public a chance to comment on the proposed
actions.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, issued Canadian AD CF-2010-07, dated February 24,
2010 (Canadian AD CF-2010-07), to correct an unsafe condition for
certain Bell Helicopter Textron Canada Limited (now Bell Textron Canada
Limited) Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4
helicopters. TCCA advises that a certain tail rotor disc assembly, sold
through Bell Helicopter Spares beginning March 2009, as an alternate,
does not conform to the approved configuration. TCCA stated operating a
helicopter with the affected tail rotor disc assembly could result in
loss of control of the helicopter.
Accordingly, the Canadian AD requires determining if an affected
part is installed, and if an affected part is found, replacement with a
non-affected part.
Discussion of Final Airworthiness Directive Comments
The FAA received a comment from one commenter, Bell Textron Canada
Limited. The following presents the comment received on the SNPRM and
the FAA's response to the comment.
Request To Add a Statement for Operators That Already Complied With the
Actions
Bell Textron Canada Limited requested that the FAA add a statement
to the effect that if the actions in Bell Helicopter Alert Service
Bulletin 206-09-123, Revision A, dated June 10, 2009; or Bell
Helicopter Alert Service Bulletin 206L-09-157, Revision A, dated June
10, 2009; have already been accomplished then the intent of the AD is
met and no further action is required. The commenter stated that many
operators will have already complied with the intent of the proposed AD
since the service information was released in 2009.
The FAA acknowledges the commenter's request and agrees to clarify.
Paragraph (g) of this AD requires accomplishing actions using Bell
Helicopter Alert Service Bulletin 206-09-123, Revision A, dated June
10, 2009; or Bell Helicopter Alert Service Bulletin 206L-09-157,
Revision A, dated June 10, 2009. Paragraph (f) of this AD states to
accomplish the required actions within the compliance times specified,
"unless already done." Therefore, if operators have accomplished the
actions required for compliance with this AD before the effective date
of this AD, no further action is necessary. The FAA has not revised
this AD in this regard.
Conclusion
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, TCCA, its technical representative,
has notified the FAA of the unsafe condition described in its AD. The
FAA reviewed the relevant data, considered the comment received, and
determined that air safety requires adopting this AD as proposed.
Accordingly, the FAA is issuing this AD to address the unsafe condition
on these helicopters.
Related Service Information Under 1 CFR Part 51
The FAA reviewed the following service information. This service
information specifies procedures to determine if an affected part is
installed, and if an affected part is found, replacement with a non-
affected part. These documents are distinct since they apply to
different helicopter models.
Bell Helicopter Alert Service Bulletin 206-09-123,
Revision A, dated June 10, 2009.
Bell Helicopter Alert Service Bulletin 206L-09-157,
Revision A, dated June 10, 2009.
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.
Costs of Compliance
The FAA estimates that this AD affects 1,493 helicopters of U.S.
registry. The FAA estimates the following costs to comply with this AD:

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 helicopters 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.
