Airworthiness Directives; Bell 

Helicopter Textron Canada, Limited, 

Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for Bell 

Helicopter Textron Canada (Bell) Model 

206, 206A, 206A–1, 206B, 206B–1, 

206L, 206L–1, 206L–3, and 206L–4 

helicopters, with Aviation Specialties 

Unlimited, Inc. (ASU), Night Vision 

Imaging System (NVIS) lighting 

modified by Supplemental Type 

Certificate SR01383SE (STC). This AD 

requires determining the date of STC 

installation, determining if the aircraft 

has an unfiltered turbine outlet 

temperature (TOT) internal overtemperature warning light, and based on 

those findings, installing an NVIS filter. 

This AD was prompted by the finding 

that an unfiltered TOT indicator overtemperature warning light, when 

illuminated, created glare and 

reflections that could degrade the pilot’s 

view while using night vision goggles 

thereby creating an unsafe condition. 

The actions of this AD are intended to 

modify any unfiltered TOT indicator 

unit over-temperature warning light by 

installing a filter to prevent degradation 

of the pilot’s vision while using night 

vision goggles and to prevent 

subsequent loss of control of the 

helicopter. 

DATES: This AD is effective July 24, 

2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

On February 3, 2012, at 77 FR 5423, 

the Federal Register published our 

notice of proposed rulemaking (NPRM), 

which proposed to amend 14 CFR part 

39 to include an AD that would apply 

to Bell Model 206, 206A, 206A–1, 206B, 

206B–1, 206L, 206L–1, 206L–3, and 

206L–4 helicopters, modified with ASU 

NVIS lighting installed per STC 

SR01383SE. That NPRM proposed to 

require, within 30 days or 50 hours 

time-in-service, whichever occurs first, 

determining the date of the STC 

installation. If the date is on or before 

April 6, 2011, or is undocumented, the 

NPRM proposed to require determining 

if the TOT indicator unit has an internal 

over-temperature warning light. If the 

unit has an unfiltered internal overtemperature warning light, the NPRM 

proposed to require installing an NVIS 

filter, part number (P/N) ASU– 

TOTGAG–1. The proposed requirements 

were intended to modify any unfiltered 

TOT indicator unit over-temperature 

warning light by installing a filter to 

prevent degradation of the pilot’s vision 

while using night vision goggles and to 

prevent subsequent loss of control of the 

helicopter. 

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 

We have reviewed the relevant 

information and determined that an 

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 except for an editorial change. 

We have revised the ‘‘Differences 

Between This Proposed AD and the 

Service Information’’ section to include 

a statement about this AD applying to 

Model 206A–1 helicopters, whereas the 

service information does not. This 

change is consistent with the intent of 

the proposal and will not increase the 

economic burden on any operator nor 

increase the scope of the AD. 

Related Service Information 

We reviewed ASU Alert Service 

Bulletin No. ASU 206–2010–11–1, dated 

November 4, 2010 (ASB) for the Bell 

Helicopter Textron 206 series 

helicopters. The ASB states to visually 

inspect each helicopter to determine if 

the TOT indicator/gauge has an internal 

over-temperature warning light 

installed. If the over-temperature 

warning light is internal, the ASB 

specifies notifying ASU. ASU states it 

will immediately ship an NVIS filter, 

P/N ASU–TOTGAG–1. 

Differences Between This AD and the 

Service Information 

This AD does not apply to helicopters 

modified by the STC after April 6, 2011, 

because a new design was approved for 

the STC on April 6, 2011, and contained 

instructions to install the NVIS overtemperature indicator light filter. This 

AD applies to Model 206A–1 

helicopters, whereas the service 

information does not. This AD does not 

require you to notify ASU.

Costs of Compliance 

We estimate that this AD will affect 

34 helicopters of U.S. Registry. 

We estimate that operators may incur 

the following costs in order to comply 

with this AD: Determining the date, 

inspecting for an unfiltered, overtemperature TOT indicator light in the 

cockpit, and installing a filter will take 

about 1.8 work-hours at $85 per workhour. A filter will cost about $300. The 

total cost will be $15,402 assuming the 

filter will be installed on the entire 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.
