SUPPLEMENTARY INFORMATION: 

Discussion

    On March 7, 2017, at 82 FR 12753, 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. The NPRM proposed to require reducing the life limit of 
certain landing gear parts by requiring the removal from service of any 
part that has reached or exceeded its new life limit before further 
flight. The proposed requirements were intended to prevent failure of a 
landing gear part, failure of a landing gear skid, and subsequent loss 
of control of the helicopter during takeoff or landing.
    The NPRM was prompted by AD No. CF-2014-28, dated August 19, 2014, 
issued by Transport Canada, which is the aviation authority for Canada, 
to correct an unsafe condition for Bell Model 429 helicopters, serial 
numbers 57001 and subsequent. Transport Canada advises that Bell has 
reduced the life limits of several landing gear components and 
accordingly revised the airworthiness limitations schedule for Model 
429 helicopters. The reduced life limits resulted from a stress 
analysis completed by Bell after the introduction of the Model 429 
helicopter to service. While the reduced life limits were originally 
published in Revision 9 of the Bell Model 429 maintenance manual, 
Transport Canada AD No. CF-2014-28 requires inserting the new 
airworthiness limitations schedule in Revision 10 of the Bell Model 429 
maintenance manual. Transport Canada states that failure to replace 
those components prior to the established airworthiness life could 
result in an unsafe condition.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we did not receive any 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 
its 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 the same type 
design and that air safety and the public interest require adopting the 
AD requirements as proposed.

Related Service Information

    We reviewed Bell Model 429 Maintenance Manual BHT-429-MM-1, Chapter 
4, Airworthiness Limitations Schedule, Revision 9, dated January 6, 
2012, which specifies airworthiness life limits and inspection 
intervals for parts installed on Model 429 helicopters. Revision 9 
reduced the life limits for the skid tube assemblies, forward crosstube 
assembly, and aft crosstube assembly.

Costs of Compliance

    We estimate that this AD affects 71 helicopters of U.S. Registry. 
We estimate that operators may incur the following costs in order to 
comply with this AD. Labor costs are estimated at $85 per work-hour. 
Calculating the life limit will take about 0.25 work-hour for an 
estimated cost of $21 per helicopter and $1,491 for the U.S. fleet. 
Replacing a skid tube assembly will take about 2 work-hours and parts 
will cost about $7,050 for an estimated replacement cost of $7,220. 
Replacing a forward cross tube assembly will take about 1.5 work-hours 
and parts will cost about $5,880 for an estimated replacement cost of 
$6,008. Replacing an aft tube assembly will take about 1.5 work-hours 
and parts will cost $6,710 for an estimated replacement cost of $6,838.

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.
