[Docket No. FAA-2013-0349; Directorate Identifier 2012-SW-058-AD]
RIN 2120-AA64

Airworthiness Directives; Bell Helicopter Textron Canada Inc. 
Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bell Helicopter Textron Canada Inc. (BHT) Model 206A, 206B, and 
206L helicopters. This proposed AD would require replacing certain 
part-numbered engine auto-relight kit control boxes. This proposed AD 
is prompted by a design review that revealed the control box chipset 
did not meet the required temperature range requirements, which could 
cause the control box to malfunction, disabling the engine auto-relight 
system. This condition could result in increased pilot workload during 
a power loss emergency and subsequent loss of control of the aircraft.

DATES: We must receive comments on this proposed AD by June 21, 2013.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your 
comments electronically.
     Fax: 202-493-2251.
     Mail: Send comments to the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590-0001.

Discussion

    Transport Canada (TC), which is the aviation authority for Canada, 
has issued TC AD No. CF-2012-19, dated June 12, 2012 (CF-2012-19), to 
correct an unsafe condition for certain serial numbered BHT Model 206A, 
206B, and 206L helicopters with an engine auto-relight kit control box 
assembly (control box assembly) part number 206-375-017-101 or 206-375-
017-103 installed. TC advises that these control box assemblies have a 
manufacturing defect which could disable the auto-relight system in the 
event of an engine flameout, subsequently requiring the pilot to re-
start the engine manually. This condition could result in increased 
pilot workload during a power loss emergency in-flight and subsequent 
loss of control of the helicopter. CF-2012-19 specifies replacing the 
affected control boxes within 4 months to correct the 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, TC, 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

    BHT has issued Alert Service Bulletin (ASB) No. 206-11-127 for 
Model 206A and 206B helicopters and ASB No. 206L-11-167 for Model 206L 
helicopters, both dated May 2, 2011. Both ASBs specify replacing the 
affected control box assembly with an upgraded control box assembly.

Proposed AD Requirements

    This proposed AD would require replacing the control box assembly 
within 4 months.

Costs of Compliance

    We estimate that this proposed AD would affect 1,357 helicopters of 
U.S. Registry. We estimate that operators may incur the following costs 
in order to comply with this AD. If installed, replacing the control 
box assembly would require about 2 work-hours at an average labor rate 
of $85 per hour and required parts would cost about $18,974, for a cost 
per helicopter of $19,144.
    According to BHT's service information, some of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected individuals. We do not control warranty coverage by 
BHT. 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 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:

[[Page 23690]]

PART 39--AIRWORTHINESS DIRECTIVES

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

Bell Helicopter Textron Canada Inc (BHT): Docket No. FAA-2013-0349; 
Directorate Identifier 2012-SW-058-AD.

(a) Applicability

    This AD applies to the following helicopters, certificated in 
any category:
    (1) BHT Model 206A and 206B helicopters, all serial numbers (S/

installed.

(b) Unsafe Condition

    This AD defines the unsafe condition as an inoperative control 
box assembly. This condition could result in a disabled auto-relight 
system, failure of the engine to relight after a flame-out, 
increased pilot workload during a power loss emergency, and 
subsequent loss of control of the helicopter.

(c) Reserved

(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.

    (1) For Model 206A and 206B helicopters, replace control box 
assembly P/N 206-375-017-101 with a control box assembly P/N 206-
375-017-105.
