We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron Canada Limited (Bell) Model 429 helicopters. This proposed AD would revise the life limit for the nose landing gear (NLG) assembly. This proposed AD is prompted by revised airworthiness limitations determined by Bell. The actions of this proposed AD are intended to prevent an unsafe condition on these helicopters.

Discussion

Transport Canada, which is the aviation authority for Canada, has
issued 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 advises that Bell has replaced the airworthiness
limitations for the NLG main fitting to bell crank bolt part number (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 (TIS). Transport Canada advises that failure to replace
components prior to established airworthiness limitations could result
in an unsafe condition.

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
its AD. We are proposing this AD because we evaluated all known
relevant information and determined that an unsafe condition is likely
to exist or develop on other helicopters of the same type design.

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.

Proposed AD Requirements

This proposed AD would revise the life limit of the NLG assembly by
requiring, before further flight, removing from service any NLG
assembly P/N 429-336-100-101 that has reached or exceeded 4,500 hours
TIS or 50,000 RIN. Thereafter, this proposed AD would require removing
from service each NLG assembly P/N 429-336-100-101 before it
accumulates 4,500 hours TIS or 50,000 RIN, whichever occurs first.

Differences Between This Proposed AD and the Transport Canada AD

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

Costs of Compliance

We estimate that this proposed AD would affect less than 75
helicopters of U.S. Registry (as this proposed AD would not apply to
Bell Model 429 helicopters with skid landing gear). At an average labor
rate of $85 per hour, replacing a NLG assembly would require 10 work-
hours, and required parts would 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 products identified in this
rulemaking action.

Regulatory Findings

We determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the 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 proposed AD and placed it in the AD docket.
