We are adopting a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 430 helicopters to require inspecting the tail rotor control tube assembly (control tube) and either repairing or replacing the control tube. This AD was prompted by two reports of failure of the control tube bonded clevis. The actions of this AD are intended to prevent failure of a control tube bonded clevis, which could lead to failure of the control tube and subsequent loss of helicopter control.

Airworthiness Directives; Bell Helicopter Textron Canada

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for Bell 
Helicopter Textron Canada (BHTC) Model 430 helicopters to require 
inspecting the tail rotor control tube assembly (control tube) and 
either repairing or replacing the control tube. This AD was prompted by 
two reports of failure of the control tube bonded clevis. The actions 
of this AD are intended to prevent failure of a control tube bonded 
clevis, which could lead to failure of the control tube and subsequent 
loss of helicopter control.

DATES: This AD is effective August 11, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 11, 
2015.

SUPPLEMENTARY INFORMATION:

Discussion

    On July 30, 2014, at 79 FR 44147, the Federal Register published 
our notice of proposed rulemaking (NPRM), which proposed to amend 14 
CFR part 39 by adding an AD that would apply to BHTC Model 430 
Helicopters, serial number 49001 through 49121, with control tube part 
number (P/N) 430-001-007-101 installed. The NPRM proposed to require 
inspecting the control tube and either repairing or replacing it. The 
proposed requirements were intended to prevent failure of a control 
tube bonded clevis, which could lead to failure of the control tube and 
subsequent loss of helicopter control.
    The NPRM was prompted by Canadian AD No. CF-2013-30, dated October 
7, 2013, issued by TCCA, which is the aviation authority for Canada, to 
correct an unsafe condition for BHTC Model 430 helicopters with control 
tube P/N 430-001-007-101. TCCA advises of two failures of the control 
tube bonded clevis caused by cracking from control tube oscillation. 
TCCA states that this situation, if not corrected, could result in the 
loss of control of the helicopter. TCCA AD No. CF-2013-30 consequently 
requires a one-time inspection of the control tube for damage and 
contacting BHTC for evaluation of the control tube if the damage 
exceeds allowable limits. If the tube is not damaged, the damage is 
within allowable limits, or BHTC Engineering determines the control 
tube can be returned to service, TCCA AD No. CF-2013-30 requires 
modifying the tube according to BHTC's service information. TCCA AD No. 
CF-2013-30 also requires replacing control tubes, P/N 430-001-007-101, 
with control tube, P/N 430-001-007-105, no later than 12 months from 
the effective date of its AD.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we received no comments on the NPRM (79 FR 44147, July 30, 
2014).

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 
our bilateral agreement with Canada, TCCA, its technical 
representative, has notified us of the unsafe condition described in 
the TCCA AD. We are issuing this AD because we evaluated all 
information provided by TCCA and determined the unsafe condition exists 
and is likely to exist or develop on other helicopters of these same 
type designs and that air safety and the public interest require 
adopting the AD requirements as proposed.

Differences Between This AD and the TCCA AD

    The TCCA AD requires submitting sketches of a control tube damaged 
beyond defined limits to BHTC for evaluation. BHTC then determines if 
the control tube can be returned to service. We make no such 
requirement in this AD.

Related Service Information Under 1 CFR Part 51

    Bell Helicopter Alert Service Bulletin (ASB) No. 430-13-51, dated 
September 3, 2013, states that BHTC received two reports of control 
tube, P/N 430-001-007-101, failing because the clevis failed due to 
fatigue caused by control tube oscillation. ASB No. 430-13-51 specifies 
a one-time inspection of control tube assembly, P/N 430-001-007-101, to 
verify if the tube has chaffing damage and indicated that a

[[Page 38614]]

mandatory replacement would follow when sufficient parts became 
available. 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 of this 
AD.

Other Related Service Information

    We reviewed Bell Helicopter Technical Bulletin 430-04-35, Revision 
B, dated March 20, 2009, which recommends that control tube, P/N 430-
001-007-101, be replaced with control tube, P/N 430-001-007-105, if 
damage exists. On June 12, 2014, Bell issued Revision A to ASB No. 430-
13-51, which set a compliance date of September 30, 2014, to remove 
control tube, P/N 430-001-007-101.

Costs of Compliance

    We estimate that this AD affects 5 helicopters of U.S. Registry and 
that labor costs average $85 a work hour. Based on these estimates, we 
expect the following costs:
     The cost of inspecting the control tube is minimal.
     Repairing the control tube requires 2 work-hours for a 
labor cost of $170.
     Replacing control tube, P/N 430-001-007-101, with control 
tube, P/N 430-001-007-105, requires 3 work-hours for a labor cost of 
$255. Parts cost $3,974 for a total cost per helicopter of $4,229.
    According to manufacturer's service information, some of the costs 
of this AD may be covered under warranty, thereby reducing the cost 
impact on affected individuals. We do not control warranty coverage by 
the manufacturer. Accordingly, we have included all costs in our cost 
estimate.

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.
    We are 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) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979);
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction; and
    (4) 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
