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 BD–100–1A10 

(Challenger 300) airplanes. This 

proposed AD was prompted by multiple 

reports of erratic electrical status 

indications on the push button 

annunciators and the engine instrument 

and crew alerting system. Certain of 

those reported incidents resulted in the 

airplane experiencing a momentary loss 

of electrical power and loss of flight 

displays. This proposed AD would 

require modification of the direct 

current power centers. We are proposing 

this AD to prevent loss of electrical 

power, which could result in the loss of 

flight displays and reduced 

controllability of the airplane. 

DATES: We must receive comments on 

this proposed AD by November 12, 

2013. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments.

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2013–05, 

dated February 22, 2012 (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: 

There have been multiple in-service 

reports of erratic electrical status indications 

on the Push Button Annunciators (PBA) and 

the Engine Instrument & Crew Alerting 

System (EICAS) while on-ground and during 

flight. Three of those reported incidents 

resulted in the aeroplane experiencing 

momentary loss of electrical power and loss 

of flight displays. 

The investigation revealed that improper 

insertion of a Printed Circuit Board (PCB) in 

a Direct Current Power Center (DCPC) may 

lead to erroneous electrical status indications 

on the PBAs and EICAS. The erroneous 

indications could mislead the pilots into 

turning off active generators and leading to 

partial or complete loss of electrical power. 

Loss of electrical power could result in the 

loss of flight displays and reduced 

controllability of the aeroplane. 

Further investigation determined that the 

design of the existing DCPC covers does not 

ensure that the PCBs will remain inserted 

into the motherboard of the DCPC. 

This [TCCA] AD mandates the 

modification of each DCPC to ensure that 

properly closed covers will retain the PCBs 

within the motherboards. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Bombardier, Inc. has issued 

Bombardier Service Bulletin 100–24–23, 

dated November 26, 2012. 

Zodiac Services has issued the 

following service bulletins. 

• Zodiac Services Service Bulletin 

320GC03Y–24–012, Revision 3, dated 

December 15, 2012. 

• Zodiac Services Service Bulletin 

970GC02Y–24–013, Revision 3, dated 

December 15, 2012. 

• Zodiac Services Service Bulletin 

975GC02Y–24–013, Revision 3, dated 

December 15, 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. 

Costs of Compliance 

We estimate that this proposed AD 

affects 92 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 per modification.

$1,568 $2,163 per modification ................ $198,996 per inspection cycle. 

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, 


TKELLEY on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 78, No. 186 / Wednesday, September 25, 2013 / Proposed Rules 58967 

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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.
