Airworthiness Directives; Bell Helicopter Textron Canada Limited Helicopters, 4685-4686 [2019-02626]

Download as PDF Federal Register / Vol. 84, No. 33 / Tuesday, February 19, 2019 / Rules and Regulations hazards and accidents that were considered in the environmental assessment for this direct final rule. Further, the safety evaluation report for the Holtec International HI–STORM 100 Cask System (ADAMS Accession No. ML003711865; May 4, 2000) identified all accident-level events and conditions, which are Design Events III and IV as defined in American National Standard Institute/American Nuclear Society 57.9–1984. These include natural phenomena and human-induced lowprobability events such as those listed in Comment 2. The NRC determined in the May 4, 2000, safety evaluation report that all potential safety consequences were considered. This direct final rule makes changes to the technical specifications of Certificate of Compliance No. 1014 for the HI–STORM 100 Cask System. However, this direct final rule makes limited and routine changes; it does not involve significant changes to the design or the fabrication of the cask system. The second comment does not raise specific safety concerns regarding the changes made in this direct final rule. The second comment did not propose a specific change or an addition that could be incorporated into this direct final rule and did not raise a relevant issue not previously addressed by the NRC. Accordingly, the second comment does not meet the criteria of a significant adverse comment. Because no significant adverse comments were received, this direct final rule will become effective as scheduled. Dated at Rockville, Maryland, this 12th day of February 2019.

SUPPLEMENTARY INFORMATION: Discussion On July 19, 2018, at 83 FR 34074, 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 Bell Model 429 helicopters with a NLG assembly part number (P/N) 429–336– 100–101 installed. The NPRM proposed to revise the life limit for the NLG assembly. The proposed requirements were intended to prevent fatigue failure of an NLG assembly, which could result PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 4685 in subsequent damage to and loss of control of the helicopter. The NPRM was prompted by Canadian AD No. CF–2016–07, dated March 4, 2016, to correct an unsafe condition for Bell Model 429 helicopters with wheeled landing gear. Transport Canada, which is the aviation authority for Canada, issued its AD after Bell replaced the airworthiness limitations for the NLG main fitting to bell crank bolt P/N M084–20H125–101 and NLG main fitting P/N M084–20H011–107 with an airworthiness limitation for the next higher assembly, NLG assembly P/ N 429–336–100–101. According to Transport Canada, the NLG assembly’s life limit is reduced to 50,000 retirement index number (RIN) or 4,500 hours time-in-service. Transport Canada advises that failure to replace components prior to established airworthiness limitations could result in an unsafe condition. Comments We gave the public the opportunity to participate in developing this AD, but we received no comments on the NPRM. 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, Transport Canada, its technical representative, has notified us of the unsafe condition described in the Transport Canada AD. We are issuing this AD because we evaluated all information provided by Transport Canada 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 Transport Canada AD The Transport Canada AD applies to certain serial-numbered helicopters, whereas this AD applies to all Bell Model 429 helicopters with the affected NLG assembly installed. Related Service Information We reviewed Bell Alert Service Bulletin No. 429–15–24, Revision A, dated September 23, 2015, which specifies updating the Bell 429 maintenance manual with Revision 24 to incorporate the revised airworthiness limitations for the NLG assembly, NLG main fitting to bellcrank bolt, and the NLG main fitting.

SUPPLEMENTARY INFORMATION:

Discussion

    On July 19, 2018, at 83 FR 34074, 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 Bell Model 429 
helicopters with a NLG assembly part number (P/N) 429-336-100-101 
installed. The NPRM proposed to revise the life limit for the NLG 
assembly. The proposed requirements were intended to prevent fatigue 
failure of an NLG assembly, which could result in subsequent damage to 
and loss of control of the helicopter.
    The NPRM was prompted by Canadian AD No. CF-2016-07, dated March 4, 
2016, to correct an unsafe condition for Bell Model 429 helicopters 
with wheeled landing gear. Transport Canada, which is the aviation 
authority for Canada, issued its AD after Bell replaced the 
airworthiness limitations for the NLG main fitting to bell crank bolt 
P/N M084-20H125-101 and NLG main fitting P/N M084-20H011-107 with an 
airworthiness limitation for the next higher assembly, NLG assembly P/N 
429-336-100-101. According to Transport Canada, the NLG assembly's life 
limit is reduced to 50,000 retirement index number (RIN) or 4,500 hours 
time-in-service. Transport Canada advises that failure to replace 
components prior to established airworthiness limitations could result 
in an unsafe condition.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we received no comments on the NPRM.

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, Transport Canada, its technical 
representative, has notified us of the unsafe condition described in 
the Transport Canada AD. We are issuing this AD because we evaluated 
all information provided by Transport Canada 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 Transport Canada AD

    The Transport Canada AD applies to certain serial-numbered 
helicopters, whereas this AD applies to all Bell Model 429 helicopters 
with the affected NLG assembly installed.

Related Service Information

    We reviewed Bell Alert Service Bulletin No. 429-15-24, Revision A, 
dated September 23, 2015, which specifies updating the Bell 429 
maintenance manual with Revision 24 to incorporate the revised 
airworthiness limitations for the NLG assembly, NLG main fitting to 
bellcrank bolt, and the NLG main fitting.

[[Page 4686]]

Costs of Compliance

    We estimate that this AD affects less than 75 helicopters of U.S. 
Registry (as this AD does not apply to Bell Model 429 helicopters with 
skid landing gear). At an average labor rate of $85 per hour, replacing 
a NLG assembly requires 10 work-hours, and required parts cost 
$104,648, for a cost of $105,498 per helicopter and up to $7,912,350 
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.
    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.
