SUPPLEMENTARY INFORMATION:
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, 206L1, 206L3, and 206L4 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

Canadian AD CF201007, to correct an unsafe condition for certain Bell Helicopter Textron Canada Limited now Bell Textron Canada Limited Model 206A, 206B, 206L, 206L1, 206L3, and 206L4 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 FAAs 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
09123, Revision A, dated June 10, 2009; or Bell Helicopter Alert Service Bulletin 206L09157, 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 commenters request and agrees to clarify. Paragraph g of this AD requires accomplishing actions using Bell Helicopter Alert Service Bulletin 206
09123, Revision A, dated June 10, 2009; or Bell Helicopter Alert Service Bulletin 206L09157, 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
