SUPPLEMENTARY INFORMATION: 

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada AD CF-2022-68, dated December 15, 2022 
(Transport Canada AD CF-2022-68), following issuance of National 
Transportation Safety Board (NTSB) Aviation Accident Preliminary Report 
Number ANC22FA041, to correct an unsafe condition for certain serial-
numbered Bell Textron Canada Limited Model 407 helicopters.
    This AD was prompted by an accident. The FAA is issuing this AD to 
address failure of the tailboom attachment hardware. See Transport 
Canada AD CF-2022-68 for additional background information.

Related Service Information Under 1 CFR Part 51

    Transport Canada AD CF-2022-68 requires checking (inspecting) the 
torque on the tailboom attachment nuts and depending on the results, 
replacing parts with new parts and stabilizing the torque. Transport 
Canada AD CF-2022-68 also requires a detailed visual inspection of the 
existing sealant application of the aft fuselage attachment fittings 
and depending on the results, removing the sealant, accomplishing a 
detailed visual inspection of the tailboom attachment structure 
(fittings, aft frames, aft fuselage bulkhead, aft section of the canted 
web, tailboom canted bulkhead, and upper and lower tailboom longerons), 
repair, and reapplying sealant. If the detailed visual inspection of 
the tailboom attachment structure was not required as a result of the 
existing sealant application inspection, Transport Canada AD CF-2022-68 
also requires accomplishing the detailed visual inspection of the 
tailboom attachment structure and depending on the results, repair. 
Transport Canada AD CF-2022-68 prohibits installing a tailboom until 
inspection of the security of the shims on the forward face of the 
tailboom bulkhead and elongation of the four bolt holes in the tailboom 
and fuselage fittings, and any repair, is accomplished. Lastly, 
Transport Canada AD CF-2022-68 requires reporting information to Bell.
    This material 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 also reviewed Bell Alert Service Bulletin 407-22-128, dated 
December 8, 2022. This service information specifies procedures for 
checking (inspecting) the torque of the aft fuselage attachment nuts 
and depending on the results, replacing parts with new parts, retaining 
the removed parts for further investigation by Bell, stabilizing the 
torque, applying corrosion preventive compound, and recording 
information. This service information also specifies, using a powerful 
light and mirror, inspecting the existing sealant application of the 
aft fuselage attachment fittings and depending on the results, removing 
the sealant, accomplishing a detailed visual inspection of the tailboom 
attachment structure (fittings, the aft frames, aft fuselage bulkhead, 
aft section of the canted web, the tailboom canted bulkhead, and upper 
and lower longerons), repair, reapplying sealant, and recording 
information. For tailbooms that are not installed on a helicopter, this 
service information specifies procedures for ensuring that the four 
shims are securely bonded in position on the forward face of the 
tailboom bulkhead, examining the four bolt holes in the tailboom and 
fuselage fittings for elongation, discarding certain removed parts, 
examining certain other parts, replacing parts, and recording 
information. Lastly, this service information specifies procedures for 
reporting the previously recorded information to Bell.

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 issuing this AD after evaluating all 
pertinent information and determining that the unsafe condition exists 
and is likely to

[[Page 79796]]

exist or develop on other helicopters of the same type design.

Requirements of This AD

    This AD requires accomplishing the actions specified in Transport 
Canada AD CF-2022-68, described previously, as IBRed, except for any 
differences identified as exceptions in the regulatory text of this AD 
and except as discussed under ``Differences Between this AD and the 
Transport Canada AD.''

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, 
Transport Canada AD CF-2022-68 is IBRed in this FAA final rule. This 
AD, therefore, requires compliance with Transport Canada AD CF-2022-68 
in its entirety through that incorporation, except for any differences 
identified as exceptions in the regulatory text of this AD. Using 
common terms that are the same as the heading of a particular section 
in Transport Canada AD CF-2022-68 does not mean that operators need 
comply only with that section. For example, where the AD requirement 
refers to ``all required actions and compliance times,'' compliance 
with this AD requirement is not limited to the section titled 
``Corrective Actions'' in Transport Canada AD CF-2022-68. Service 
information referenced in Transport Canada AD CF-2022-68 for compliance 
will be available at regulations.gov under Docket No. FAA-2022-1658 
after this final rule is published.

Differences Between This AD and the Transport Canada AD

    Transport Canada AD CF-2022-68 requires torque checks, whereas this 
AD requires torque inspections because those actions must be 
accomplished by a mechanic that meets the requirements of 14 CFR part 
65 subpart D. Transport Canada AD CF-2022-68 requires retaining removed 
parts for further investigation by Bell, whereas this AD does not 
include that requirement. However, operators may choose to retain the 
parts for further investigation by Bell as this AD does not prohibit an 
operator from doing so. Transport Canada AD CF-2022-68 does not specify 
the compliance time to accomplish the repetitive (stabilization) torque 
checks (inspections) in its AD, whereas this AD does. Transport Canada 
AD CF-2022-68 requires contacting Bell Product Support Engineering for 
a repair or instructions to rectify any defect, whereas this AD 
requires a repair done in accordance with a certain approval. Lastly, 
Transport Canada AD CF-2022-68 specifies to report inspection results 
within 30 days, whereas this AD requires reporting inspection results 
within 10 days instead.

Interim Action

    The FAA considers this AD interim action. If final action is later 
identified, the FAA might consider further rulemaking then.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies foregoing notice and comment prior to adoption of this rule 
because the tailboom attachment hardware was involved in an accident 
where the tailboom attachment hardware failed during flight, resulting 
in the tailboom separating from the helicopter and loss of control of 
the helicopter. Failure of the tailboom attachment hardware could occur 
during any phase of flight without any previous indication. As the FAA 
has no information pertaining to the extent of this condition of the 
tailboom attachment hardware that may currently exist in helicopters or 
how quickly the condition may propagate to failure, the compliance time 
to complete the required inspections is within 25 hours time-in-service 
or 30 days, whichever occurs first, which is shorter than the time 
necessary for the public to comment and for publication of the final 
rule. Accordingly, notice and opportunity for prior public comment are 
impracticable and contrary to the public interest pursuant to 5 U.S.C. 
553(b)(3)(B).
    In addition, the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) for making this amendment effective in less than 30 days, 
for the same reasons the FAA found good cause to forego notice and 
comment.

Comments Invited

    The FAA invites you to send any written data, views, or arguments 
about this final rule. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2022-1658; Project Identifier MCAI-
2022-01597-R'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the final rule, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this final rule because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this final rule.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this AD, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this AD. Submissions containing CBI should be sent to Kristi 
Bradley, Program Manager, COS Program Management Section, Operational 
Safety Branch, Compliance & Airworthiness Division, FAA, 10101 Hillwood 
Pkwy., Fort Worth, TX 76177; telephone (817) 222-5110; email 
[email protected]. Any commentary that the FAA receives that is 
not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

[[Page 79797]]

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because the FAA has determined 
that it has good cause to adopt this rule without prior notice and 
comment, RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 839 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.
    Torque inspecting the tailboom attachment hardware, and visually 
inspecting the sealant and the tailboom attachment structure takes 
about 2 work-hours for an estimated cost of $170 per helicopter and 
$142,630 for the U.S. fleet. If required, replacing a bolt and nut set 
takes about 2 work-hours and parts cost about $170 for an estimated 
cost of $340 per replacement. Stabilizing the torque takes about 1 
work-hour for an estimated cost of $85 per instance. The FAA has no 
data to determine the costs to accomplish approved repairs. Reporting 
information takes about 1 work-hour for an estimated cost of $85 per 
helicopter and $71,315 for the U.S. fleet.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a currently valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to be 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866, and
    (2) Will not affect intrastate aviation in Alaska.
