AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc., Model DHC–8–102, 

–103, and –106 airplanes; and DHC–8– 

200 and DHC–8–300 series airplanes. 

This proposed AD was prompted by a 

report of a beta warning horn (BWH) 

system failing to activate when the beta 

mode was triggered. This proposed AD 

would require modifying the BWH 

microswitch installation. We are 

proposing this AD to prevent the 

inadvertent activation of ground beta 

mode during flight, which could lead to 

engine overspeed, engine damage or 

failure, and consequent reduced 

controllability of the airplane.

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2012–01R1, 

dated March 6, 2013 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

* * * * * 

During an on-ground Beta Warning Horn 

(BWH) system check conducted in the wake 

of an in-flight Beta range operation incident 

on a DHC–8 Series 200 aeroplane, it was 

discovered that the BWH system failed to 

activate when the Beta mode was triggered. 

An investigation by Bombardier had 

determined that the deformation of the 

flexible center console cover could cause the 

BWH system triggering microswitch to 

malfunction, resulting in dormant failure of 

the BWH system. To mitigate the safety risk 

by minimizing the risk exposure period, 

[TCCA] * * * mandate[d] a 50 hours 

periodic operational test of the BWH system 

functionality. 

To address the root cause of the subject 

problem, Bombardier has issued Service 

Bulletin (SB) 8–76–33 that modifies the BWH 

microswitch installation by replacing the 

BWH microswitch attachment bracket with a 

new, more robust bracket that is not affected 

by deformation of the center console cover. 

[TCCA] AD CF–2012–01 is therefore revised 

to mandate compliance with SB 8–76–33 as 

terminating action for the 50 hours periodic 

operational test requirement. 

The unsafe condition is the inadvertent 

activation of ground beta mode during 

flight, which could lead to engine 

overspeed, engine damage or failure, 

and consequent reduced controllability 

of the airplane. You may examine the 

MCAI in the AD docket on the Internet 

at http://www.regulations.gov by 

searching for and locating it in Docket 

No. FAA–2013–1025. 

Relevant Service Information 

Bombardier, Inc., has issued Service 

Bulletin 8–76–33, dated December 13, 

2012. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

Although the MCAI includes an 

operational test of the BWH system, this 

proposed AD does not require that 

action. Once the actions required by this 

AD are done, the modification of the 

BWH microswitch installation 

adequately addresses the identified 

unsafe condition. Also, AD 2005–13–35, 

Amendment 39–14172 (70 FR 48854, 

August 22, 2005), for all Bombardier, 

Inc., Model DHC–8–100, DHC–8–200, 

and DHC–8–300 series airplanes, 

includes a requirement for certain 

airplanes to perform operational checks 

of the beta lockout system. This 

difference has been coordinated with 

TCCA. 

Costs of Compliance 

We estimate that this proposed AD 

affects 94 airplanes of U.S. registry. We 

estimate the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Modification ............................. 7 work-hours × $85 per hour = $595 ..................................... $117 $712 $66,928 

According to the manufacturer, 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 for affected individuals. As a 

result, 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 


emcdonald on DSK67QTVN1PROD with PROPOSALS
Federal Register / Vol. 78, No. 238 / Wednesday, December 11, 2013 / Proposed Rules 75293 

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 above, 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; 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.
