AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Hawker Beechcraft Corporation (Type 

Certificate previously held by Raytheon 

Aircraft Company; Beech Aircraft 

Corporation) Model 400A airplanes. 

This proposed AD was prompted by a 

report that the wiring for the 5-volt 

direct current (DC) system is undersized 

and does not have adequate circuit 

protection for the smaller gauge wire. 

This proposed AD would require 

installing an in-line fuse in the 5-volt 

DC system for each of the five 

instrument lighting control power 

supplies. We are proposing this AD to 

prevent failure of the wiring, which 

could result in smoke in the cockpit, 

loss of cockpit lighting, and potential 

damage to surrounding wiring for other 

cockpit equipment such as the stick 

shaker function or angle-of-attack 

indicators. 

DATES: We must receive comments on 

this proposed AD by December 20, 

2012. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2012–1111; Directorate Identifier 2012– 

NM–114–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We received a report that the wiring 

for the 5-volt DC system is undersized 

and does not have adequate circuit 

protection for the smaller gauge wire. 

The wire is adequate for normal 

electrical loads, but it cannot safely 

handle the power supply’s maximum 

current. This condition, if not corrected, 

could result in failure of the wiring, 

which could result in smoke in the 

cockpit, loss of cockpit lighting, and 

potential damage to surrounding wiring 

for other cockpit equipment such as the 

stick shaker function or angle-of-attack 

indicators. 

Relevant Service Information 

We reviewed Hawker Beechcraft 

Mandatory Service Bulletin SB 33–4002, 

dated October 2010. The service 

information describes procedures for 

installing an in-line fuse in the 5-volt 

DC system for each of the five 

instrument lighting control power 

supplies. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously. 

Clarification of Service Bulletin Note 

The Hawker Beechcraft Mandatory 

Service Bulletin SB 33–4002, dated 

October 2010, includes a note in the 

Accomplishment Instructions to inform 

operators to contact Hawker Beechcraft 

‘‘should any difficulty be encountered’’ 

WREIER-AVILES on DSK5TPTVN1PROD with PROPOSALS

66412 Federal Register / Vol. 77, No. 214 / Monday, November 5, 2012 / Proposed Rules 

in accomplishing the service bulletin. 

We have included a statement in 

paragraph (g) of this proposed AD to 

clarify that any deviation from the 

instructions provided in that service 

bulletin must be approved as an 

alternative method of compliance under 

paragraph (i) of this proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

affects 421 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 

Installation ............................................................. 10 work-hours × $85 per hour = $850 ................. $285 $1,135 $477,835 

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 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety.

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–8–400 

series airplanes. This proposed AD was 

prompted by reports of chafing found on 

the main landing gear (MLG) yoke. The 

chafing was attributed to contact 

between the nacelle fire detection wires 

and the MLG yoke. This proposed AD 

would require inspections of the nacelle 

fire detection wires and the MLG yoke 

for damage; replacing nacelle fire 

detection wires, if necessary; repairing 

the MLG yoke, if necessary; and 

installing new brackets and associated 

hardware to secure the fire detection 

wires. We are proposing this AD to 

prevent chafing between the nacelle fire 

detection wires and the MLG yoke. 

Chafing could lead to cracking and 

subsequent failure of the MLG yoke, 

which could adversely affect the safe 

landing of the airplane. In addition, 

chafing of the nacelle fire detection 

wires could cause them to fail and 

prevent the detection of a fire in the 

nacelle assembly. 

DATES: We must receive comments on 

this proposed AD by December 20, 

2012.

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2012–15, 

dated April 30, 2012 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

There have been two (2) in-service reports 

of chafing found on the main landing gear 

(MLG) yoke. The chafing was attributed to 

contact between the nacelle fire detection 

wire and the MLG yoke. This chafing may 

lead to cracking and subsequent failure of the 

MLG yoke. 

Failure of the MLG yoke could adversely 

affect the safe landing of the aeroplane. In 

addition, failure of the fire detection wire 

could prevent the detection of a fire in the 

nacelle assembly. 

This [Canadian] Airworthiness Directive 

(AD) mandates the [detailed] inspection of 

the nacelle fire detection wires and [detailed 

inspection of the] MLG yoke for damage 

[chafing, nicks, cracking] and the installation 

of new brackets to secure the fire detection 

wire to prevent chafing against the MLG yoke 

[and corrective actions if necessary]. 

Corrective actions include replacing 

damaged wires with new wires and 

repairing the MLG yoke. You may 

obtain further information by examining 

the MCAI in the AD docket.
