We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron Canada Limited (Bell) Model 429 helicopters. This proposed AD would reduce the life limit of certain landing gear parts and is prompted by a stress analysis. The proposed actions are intended to address an unsafe condition on these products.

Discussion

    Transport Canada, which is the aviation authority for Canada, has 
issued AD No. CF-2014-28, dated August 19, 2014, 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.

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 products of the same type design.

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.

Proposed AD Requirements

    This proposed AD would reduce the life limit of certain landing 
gear parts by requiring the removal from service of

[[Page 12754]]

any part that has reached or exceeded its new life limit before further 
flight.

Costs of Compliance

    We estimate that this proposed AD would affect 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 would 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 would take about 2 work-hours and 
parts would cost about $7,050 for an estimated replacement cost of 
$7,220. Replacing a forward cross tube assembly would take about 1.5 
work-hours and parts would cost about $5,880 for an estimated 
replacement cost of $6,008. Replacing an aft tube assembly would take 
about 1.5 work-hours and parts would 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 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bell Helicopter Textron Canada Limited: Docket No. FAA-2017-0174; 
Directorate Identifier 2014-SW-059-AD.

(a) Applicability

    This AD applies to Bell Helicopter Textron Canada Limited Model 
429 helicopters, certificated in any category.

(b) Unsafe Condition

    This AD defines the unsafe condition as a landing gear part 
remaining in service beyond its fatigue life. This condition could 
result in failure of a landing gear part, failure of a landing gear 
skid, and subsequent loss of control of the helicopter during 
takeoff or landing.

(c) Comments Due Date

    We must receive comments by May 8, 2017.

(d) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(e) Required Actions

    Before further flight, determine the accumulated retirement 
index number (RIN) for each part and remove it from service if it 
has reached or exceeded its life limit as follows. Thereafter, 
remove each part from service on or before reaching its life limit. 
For purposes of this AD, a run-on landing is defined as a landing 
with forward ground travel of the helicopter greater than 3 feet 
(0.91 m) with weight on skids.
    (1) For Skid Tube Assembly part number (P/N) 429-700-101, 429-
700-102, and 429-030-586-107: 16,000 RIN. Count 1 RIN for each 
landing; count 81 RIN for each run-on landing; and count 117 RIN for 
each autorotation landing.
    (2) For Forward Crosstube Assembly P/N 429-712-101: 10,000 RIN. 
Count 1 RIN for each landing; count 50 RIN for each run-on landing; 
and count 118 RIN for each autorotation landing.
    (3) Aft Crosstube Assembly P/N 429-723-108: 30,000 RIN. Count 1 
RIN for each landing; count 32 RIN for each run-on landing; and 
count 186 RIN for each autorotation landing.

(f) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Safety Management Group, FAA, may approve AMOCs 
for this AD. Send your proposal to: Matt Fuller, Senior Aviation 
Safety Engineer, Safety Management Group, Rotorcraft Directorate, 
FAA, 10101 Hillwood Pkwy., Fort Worth, TX 76177; telephone (817) 
222-5110; email [email protected].
    (2) For operations conducted under a 14 CFR part 119 operating 
certificate or under 14 CFR part 91, subpart K, we suggest that you 
notify your principal inspector, or lacking a principal inspector, 
the manager of the local flight standards district office or 
certificate holding district office before operating any aircraft 
complying with this AD through an AMOC.
