Background
Transport Canada, which is the aviation authority for Canada,
issued Transport Canada AD CF-2022-46, dated August 12, 2022 (Transport
Canada AD CF-2022-46), to correct an unsafe condition for Bell Textron
Inc., Model 204B, 205A-1, 205B, 212, 214B, 214B-1, 412, 412 CF, and 412
EP helicopters, which are modified in accordance with Transport Canada
Supplemental Type Certificate (STC) SH01-9 and installed with Dart
Aerospace Ltd. high gear forward crosstube part number (P/N) D212-664-
101 or P/N D212-664-101B. Transport Canada advises of reports of two
in-service failures of Dart Aerospace Ltd. forward crosstube P/N D212-
664-101 on Bell Textron Inc., Model 412 helicopters. Transport Canada
further advises the forward crosstube fractured during landing, and
both failures were due to fatigue damage and involved forward
crosstubes which had accumulated more than 20,000 landings.
Additionally, Transport Canada advises if a forward crosstube fails
without timely mitigating action from the pilot during landing, the
helicopter could contact the ground causing damage to the fuselage and
injury to occupants. Transport Canada advises that Dart Aerospace Ltd.,
issued a revision to the Airworthiness Limitations Section (ALS) of its
Instructions for Continued Airworthiness, which establishes a new lift
limit for forward crosstubes P/N D212-664-101 and P/N D212-664-101B.
Accordingly, Transport Canada AD CF-2022-46 requires incorporating
the newly established airworthiness limitations for forward crosstubes
P/N D212-664-101 and P/N D212-664-101B by amending Chapter 4
Airworthiness Limitations of Dart Aerospace Ltd., ICA-D212-664 by
inserting Revision 12, dated September 30, 2021. Transport Canada AD
CF-2022-46 also requires removing forward crosstubes P/N D212-664-101
and P/N D212-664-101B with more than 20,000 landings from service and
allows the use of superseding or later revisions of the ALS that are
approved by Transport Canada.
FAA STC No. SR01298NY approves the installation of forward
crosstubes P/N D212-664-101 and P/N D212-664-101B on Bell Textron Inc.,
Model 204B, 205A, 205A-1, 205B, 210, 212, 412, 412CF, and 412EP
helicopters; Erickson 214 Holdings, LLC, Model 214B and 214B-1;
Leonardo S.p.a. Model AB412 and AB412 EP helicopters; and restricted
category Model HH-1K, TH-1F, TH-1L, UH-1A, UH-1B, UH-1E, UH-1F, UH-1H,
UH-1L, and UH-1P helicopters. Accordingly, this AD applies to those
model helicopters.
You may examine Transport Canada AD CF-2022-46 in the AD docket at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2022-1402.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Chapter 4--Airworthiness Limitations (04-00-00),
approved March 23, 2022, of Dart Aerospace Ltd., Instructions for
Continued Airworthiness, ICA-D212-664, Crosstube Installation, Revision
12, dated September 30, 2021 (Dart ICA-D212-664 Rev 12). This service
information specifies life limits for various part-numbered crosstubes.
This revision of the service information adds a newly established life
limit for forward crosstubes P/N D212-664-101 and P/N D212-664-101B.
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 ADDRESSES.
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 determining that
the unsafe condition described previously is likely to exist or develop
on other helicopters the same type designs.
AD Requirements
This AD requires determining the total number of landings on
forward crosstubes P/N D212-664-101 and P/N D212-664-101B, and if the
total number of landings cannot be determined, calculating the total
number of landings. For a forward crosstube that has accumulated 20,000
or more total landings or if the total number of landings cannot be
calculated, this AD requires removing the forward crosstube from
service. This AD also requires incorporating requirements
(airworthiness limitations) into existing maintenance records, which
are identified in Dart ICA-D212-664 Rev 12, as described previously.
ADs Mandating Airworthiness Limitations
The FAA has previously mandated airworthiness limitations by
mandating each airworthiness limitation task (e.g., inspections and
replacements (life limits)) as an AD requirement or issuing ADs that
require revising the ALS of the existing maintenance manual or
instructions for continued airworthiness to incorporate new or revised
inspections and life limits. This AD, however, requires operators to
incorporate into maintenance records required by 14 CFR 91.417(a)(2) or
135.439(a)(2), as applicable for your rotorcraft, the requirements
(airworthiness limitations) identified in the ALS service information,
as described previously. The FAA does not intend this as a substantive
change. For these ADs, the ALS requirements for operators are the same
but are complied with differently. Requiring the incorporation of the
new ALS requirements into the existing maintenance records, rather than
requiring individual ALS tasks (e.g., repetitive inspections and
replacements), requires operators to record AD compliance once after
updating the maintenance records, rather than after every time the ALS
task is completed.
Differences Between This AD and the Transport Canada AD
Transport Canada AD CF-2022-46 applies to Bell Textron Inc. Model
204B, 205A-1, 205B, 212, 214B, 214B-1, 412, 412 CF, and 412 EP
helicopters which are modified in accordance with Transport Canada STC
SH01-9 and installed with Dart Aerospace Ltd. high gear forward
crosstube P/N D212-664-101 or P/N D212-664-101B; whereas, this AD
applies to Bell Textron Inc.,
[[Page 66944]]
Model 204B, 205A, 205A-1, 205B, 210, 212, 412, 412CF, and 412EP
helicopters; Erickson 214 Holdings, LLC, Model 214B and 214B-1
helicopters; Leonardo S.p.a. Model AB412 and AB412 EP helicopters; and
all restricted category Model HH-1K, TH-1F, TH-1L, UH-1A, UH-1B, UH-1E,
UH-1F, UH-1H, UH-1L, and UH-1P helicopters, with Dart Aerospace Ltd.
high gear forward crosstube P/N D212-664-101 or P/N D212-664-101B
installed under (FAA) STC No. SR01298NY.
This AD requires determining the total number of landings on an
affected forward crosstube, defines what is considered a ``landing''
for the purposes of this AD, requires a particular method to calculate
the total number of landings if it cannot be determined, and requires
removing an affected forward crosstube for which the total number of
landings cannot be determined from service, whereas, Transport Canada
AD CF-2022-46 does not contain that information or those actions.
Transport Canada AD CF-2022-46 allows the use of superseding or later
revisions of Dart ICA-D212-664 Rev 12 that are approved by Transport
Canada, whereas this AD does not because referring to documents that do
not exist at the time a final rule is published violates Office of the
Federal Register (OFR) regulations regarding approval of materials
``incorporated by reference'' in rules.
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 forward crosstube is a component of a helicopter's landing
gear and is critical to the control of the helicopter during landing.
The FAA also has no information pertaining to the number of forward
crosstubes that have already met or exceeded the newly established life
limit, and fatigue beyond allowable limits of a forward crosstube could
lead to instantaneous failure at any time without any previous
indications. In light of this, the initial actions required by this AD
must be accomplished before further flight. This compliance time 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.
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 up to 594 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.
Determining the total number of landings on an affected forward
crosstube takes about 0.5 work-hour for an estimated cost of $43 per
helicopter and up to $25,542 for the U.S. fleet. Removing an affected
forward crosstube from service and replacing it with an airworthy part
takes about 8 work-hours and parts cost about $6,487 for an estimated
cost of $7,167 per helicopter. Incorporating requirements
(airworthiness limitations) into existing maintenance records takes
about 2 work-hours for an estimated cost of $170 per helicopter and up
to $100,980 for the U.S. fleet.
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, and
(2) Will not affect intrastate aviation in Alaska.

(d) Subject
Joint Aircraft System Component (JASC) Code: 3222, Nose/Tail
Landing Gear Structure/Axle.
(e) Unsafe Condition
This AD was prompted by reports of two in-service failures of
forward crosstubes due to fatigue damage and the issuance of newly
established life limits. The FAA is issuing this AD to prevent
failure of a forward crosstube, which could result in collapse of
the landing gear and subsequent loss of control of the helicopter
during landing.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
(1) Before further flight after the effective date of this AD,
accomplish the actions in paragraph (g)(1)(i) and (ii) of this AD.
(i) Determine the total number of landings on the forward
crosstube. For the purposes of this AD, a landing is counted anytime
a helicopter contacts the ground regardless of the duration of the
landing and regardless of whether the engine is shutdown. If the
total number of landings cannot be determined, calculate the total
number of landings by multiplying the total hours time-in-service on
the forward crosstube by 10.
(ii) For a forward crosstube that has accumulated 20,000 or more
total landings or if the total number of landings of a forward
crosstube cannot be calculated as required in paragraph (g)(1)(i) of
this AD, before further flight, remove the forward crosstube from
service.
(2) Within 30 days after the effective date of this AD,
incorporate into maintenance records required by 14 CFR 91.417(a)(2)
or 135.439(a)(2), as applicable for your helicopter, the
requirements (airworthiness limitations) specified in Chapter 4--
Airworthiness Limitations (04-00-00), approved March 23, 2022, of
Dart Aerospace Ltd., Instructions for Continued Airworthiness, ICA-
D212-664, Crosstube Installation, Revision 12, dated September 30,
2021.
(h) Provisions for Alternative Requirements (Airworthiness Limitations)
After the actions required by this paragraph (g)(2) of this AD
have been done, no alternative actions and associated thresholds and
intervals, including life limits, may be used unless the actions or
intervals are approved as an alternative method of compliance (AMOC)
in accordance with the procedures specified in paragraph (i)(1) of
this AD.
(i) Alternative Methods of Compliance (AMOCs)
(1) The Manager, International Validation Branch, FAA, has the
authority to approve AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19,
send your request to your principal inspector or local Flight
Standards District Office, as appropriate. If sending information
directly to the manager of the International Validation Branch, send
it to the attention of the person identified in paragraph (j) of
this AD. Information may be emailed to: <a href="/cdn-cgi/l/email-protection#e7decaa6b1b4caa6aeb5cad0d4d7caa6aaa8a4a7818686c9808891"><span class="__cf_email__" data-cfemail="f6cfdbb7a0a5dbb7bfa4dbc1c5c6dbb7bbb9b5b6909797d8919980">[email protected]</span></a>.
