Airworthiness Directives; Bell Textron Canada Limited Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bell Textron Canada Limited Model 429 helicopters. This AD was 
prompted by reports of failed rivets between the tailboom skin and the 
tail rotor (TR) gearbox support assembly. This AD requires visually 
inspecting the external surface of the TR gearbox support assembly, 
borescope inspecting or visually inspecting the inside of the tailboom 
for certain conditions, and performing a tactile inspection. Depending 
on the results of the inspections, this AD requires removing certain 
rivets from service or repairing gaps in accordance with an approved 
method. This AD also requires repeating these inspections within 
certain intervals. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective November 28, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain document listed in this AD as of November 28, 
2022.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to Bell Textron Canada 
Limited Model 429 helicopters, serial numbers (S/N) 57001 and 
subsequent. The NPRM published in the Federal Register on December 23, 
2021 (86 FR 72891). In the NPRM, the FAA proposed to require visually 
inspecting the external surface of the TR gearbox support assembly, 
borescope inspecting or visually inspecting the inside of the tailboom 
for certain conditions, and performing a tactile inspection. Depending 
on the results of the inspections, the NPRM proposed to require 
removing certain rivets from service or repairing gaps in accordance 
with FAA-approved methods. The NPRM also proposed to require repeating 
these inspections within certain intervals.

[[Page 64153]]

    The NPRM was prompted by Transport Canada AD CF-2021-15, dated 
April 14, 2021 (Transport Canada AD CF-2021-15), issued by Transport 
Canada, which is the aviation authority for Canada, to correct an 
unsafe condition for Bell Textron Canada Limited Model 429 helicopters, 
S/N 57001 and subsequent. Transport Canada advises of multiple in-
service reports of failed rivets at the joint between the tailboom skin 
and the TR gearbox support assembly part number (P/N) 429-034-701-101 
or P/N 429-035-705-101. Transport Canada states that in-service reports 
also revealed a quality escape resulted in a gapping condition between 
the tailboom skin and the TR gearbox support fitting at some locations 
around the joint, and that rivets of inadequate grip length have been 
installed at the affected joint. This condition, if not addressed, 
could result in progressive deterioration of the joint structural 
integrity, detachment of the TR gearbox support assembly and loss of 
control of the helicopter.
    Accordingly, Transport Canada AD CF-2021-15 requires, for certain 
serial-numbered helicopters, an initial visual inspection of the rivets 
at the TR gearbox support assembly for signs of failed rivets or 
inadequate grip length. Transport Canada AD CF-2021-15 also requires, 
for all serial-numbered helicopters defined in the applicability, 
repeating the initial visual inspection at intervals not to exceed 400 
hours air time or 12 months, whichever occurs first. Transport Canada 
AD CF-2021-15 also requires repair or replacement of affected parts if 
discrepancies are found. Transport Canada considers its AD an interim 
action and states that further AD action may follow.
    After the FAA issued the NPRM, the FAA issued a supplemental notice 
of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD 
that would apply to Bell Textron Canada Limited Model 429 helicopters, 
S/N 57001 and subsequent. The SNPRM published in the Federal Register 
on April 22, 2022 (87 FR 24077). The SNPRM proposed to require visually 
inspecting the external surface of the TR gearbox support assembly, 
borescope inspecting or visually inspecting the inside of the tailboom 
for certain conditions, and performing a tactile inspection. Depending 
on the results of the inspections, the SNPRM proposed to require 
removing certain rivets from service or repairing gaps in accordance 
with FAA-approved methods. The SNPRM also proposed to require repeating 
these inspections within certain intervals.
    The SNPRM was prompted by the FAA's determination that due to 
thermal cycling, the compliance times in the NPRM should be revised to 
include calendar compliance times. According to Bell, thermal cycling 
is independent of flight hours (FH) and can occur when an aircraft is 
stationary and is also a significant contributor to the unsafe 
condition. Accordingly, the FAA determined the proposed paragraph (g) 
of the NPRM had to be revised by including calendar compliance times. 
Also, after the NPRM was issued, the FAA determined the proposed 
paragraph (g)(1)(iii) of the NPRM had to be revised by deleting the 
word ``not'' when referring to whether or not a rivet comes out when 
pulled with pliers or when pulled by hand. This wording was incorrect 
and the correct wording should only state ``does.'' Accordingly, these 
changes were included in the SNPRM.

Discussion of Final Airworthiness Directive

Comments

    The FAA received one comment from Air Methods. The following 
presents the comment received on the SNPRM and the FAA's response.

Request for More Information

    The commenter stated Transport Canada AD CF-2021-15 requires 
replacing any rivets and repairing any gaps that exceed 0.005 in (0.127 
mm) in accordance with an approved Bell structural repair scheme, 
whereas the proposed AD would require removing the rivets from service 
and repairing gaps in accordance with an FAA-approved method instead. 
The commenter stated that Bell does not normally provide FAA-approved 
documentation and requested that the FAA clarify whether the FAA is 
mandating receiving both a Bell Canada approval document and a separate 
8110 from the FAA.
    The FAA has revised paragraphs (g)(1)(i)(B) and (g)(1)(ii)(A)(2) of 
this final rule from ``repair the gaps in accordance with an FAA-
approved method'' to ``repairing any gaps in accordance with a method 
approved by the Manager, General Aviation & Rotorcraft Section, 
International Validation Branch, FAA; or Transport Canada; or Bell 
Textron Canada Limited's Transport Canada Design Approval Organization 
(DAO). If approved by the DAO, the approval must include the DAO-
authorized signature.'' The FAA also revised the Costs of Compliance 
section of this final rule to reflect these changes. These revisions 
clarify that operators are not limited to a single method of repair in 
order for a helicopter to be approved for return to service.

Additional Changes Since the SNPRM was Issued

    Since the FAA issued the SNPRM, the FAA has revised paragraphs 
(g)(1)(i)(A) and (B) of this final rule by adding the words ``replace 
the rivets removed from service by paragraph (g)(1)(i) of this AD with 
airworthy rivets.'' The FAA determined this revision clarifies which 
rivets should be replaced and that an airworthy rivet must be installed 
when these rivets are removed from service.
    The FAA has also revised paragraphs (g)(1)(i) and (g)(1)(ii)(A) and 
(B) of this final rule by adding the words ``remove these rivets from 
service.'' The FAA determined this revision clarifies which rivets 
should be removed from service. Additionally, the FAA revised this 
final rule by adding paragraphs (g)(1)(ii)(A)(1) and (2) to this final 
rule, which describe the corrective actions that are required as a 
result of paragraph (g)(1)(ii)(A). The FAA determined this revision was 
necessary to clarify which rivets should be removed from service and 
replaced after the gap measurements.
    The FAA has also revised paragraph (g)(1)(ii)(B) of this final rule 
by adding the words ``replace them with airworthy rivets.'' The FAA 
determined this revision clarifies that an airworthy rivet must be 
installed to replace the rivet(s) that were removed from service.
    Additionally, the FAA revised the corrective action for any gaps 
that equal 0.005 in (0.127 mm). In the SNPRM, the FAA proposed 
repairing those gaps in accordance with an FAA-approved method and 
removing the rivets from service. In this final rule, the FAA requires 
removing certain rivets from service and replacing them with airworthy 
rivets for that condition instead.
    Finally, the FAA revised paragraph (g)(1)(iii) of this final rule 
by adding the words ``remove any rivet from service that comes out when 
pulled with pliers or when pulled by hand and replace with an airworthy 
rivet.'' The FAA determined this revision was necessary to clarify 
which rivets should be removed from service if corrective action is 
needed as a result of the tactile inspection and that an airworthy 
rivet must be installed to replace the rivet that was removed from 
service.

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

[[Page 64154]]

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 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. Except for minor editorial changes and any other 
changes described previously, this AD is adopted as proposed in the 
SNPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Bell Alert Service Bulletin (ASB) 429-19-47, 
Revision B, dated January 27, 2021. This service information specifies 
procedures for an initial and repetitive general visual inspections and 
detailed inspections of the affected rivets at the joint between the 
tailboom skin and the TR gearbox support assembly. This service 
information also specifies procedures for replacing the affected rivets 
and repairing the gaps in accordance with an approved Bell structural 
repair scheme.
    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 also reviewed Bell ASB 429-19-47, dated August 28, 2019 
(ASB 429-19-47), and Bell ASB 429-19-47, Revision A, dated November 2, 
2020 (ASB 429-19-47 Rev A). ASB 429-19-47 specifies the same general 
visual inspection as ASB 429-19-47 Rev A however, ASB 429-19-47 Rev A 
introduces a repetitive inspection and specifies corrective actions if 
any discrepant rivets are found. ASB 429-19-47 Rev A specifies the same 
procedures for the initial and repetitive general visual inspections 
and detailed inspections as ASB 429-19-47 Rev B however, ASB 429-19-47 
Rev B revises the compliance section, description section, and 
materials section, and also the accomplishment instructions.

Interim Action

    The FAA considers this AD to be an interim action. Once final 
action has been identified, the FAA might consider further rulemaking.

Differences Between This AD and the Transport Canada AD

    If there are any gaps that exceed 0.005 in (0.127 mm), Transport 
Canada AD CF-2021-15 requires replacing the rivets, repairing the gaps 
in accordance with an approved Bell structural repair scheme, and 
submitting certain information to the manufacturer. Whereas, if there 
are any gaps that exceed 0.005 in (0.127 mm), this AD requires removing 
the rivets from service and replacing the rivets with airworthy rivets. 
This AD also requires repairing those gaps in accordance with a method 
approved by the Manager, General Aviation & Rotorcraft Section, 
International Validation Branch, FAA; or Transport Canada; or Bell 
Textron Canada Limited's Transport Canada DAO instead. If there are any 
gaps that are 0.005 in (0.127 mm) or less, Transport Canada AD CF-2021-
15 requires replacing the rivets, whereas this AD requires removing the 
rivets from service and replacing them with airworthy rivets.

Costs of Compliance

    The FAA estimates that this AD affects 120 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.
    Visually inspecting the surface of the TR gearbox support assembly 
takes about 0.5 work-hour for an estimated cost of $43 per helicopter 
per inspection and $5,160 for the U.S. fleet per inspection.
    If required, replacing an affected rivet takes about 1 work-hour 
and parts cost about $110 per rivet for an estimated cost of $195 per 
rivet replacement.
    If required, measuring gaps takes about 0.5 work-hour for an 
estimated cost of $43 per helicopter.
    If required, repairing a gap in accordance with an FAA-approved 
method takes up to about 1 work-hour for an estimated cost of up to $85 
per repair. The FAA has no way to determine the cost estimate of 
repairing a gap using a method approved by Transport Canada, or Bell 
Textron Canada Limited's Transport Canada DAO.
    Visually inspecting or borescope inspecting the inside of the 
tailboom takes about 0.5 work-hour for an estimated cost of $43 per 
helicopter per inspection and $5,160 for the U.S. fleet per inspection.
    Performing a tactile inspection takes about 0.5 work-hour for an 
estimated cost of $43 per helicopter per inspection and $5,160 for the 
U.S. fleet per inspection.

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.
