Airworthiness Directives; Bombardier, 

Inc., Airplanes 

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 CL–600–2C10 

(Regional Jet Series 700, 701, & 702), 

Model CL–600–2D15 (Regional Jet 

Series 705), Model CL–600–2D24 

(Regional Jet Series 900), and Model 

CL–600–2E25 (Regional Jet Series 1000) 

airplanes. This proposed AD was 

prompted by a report of a smoke-incabin event due to a non-sustaining 

electrical fire. This proposed AD would 

require installation of protective sleeves 

on the bonding jumper wires of affected 

galleys and lavatories. We are proposing 

this AD to address the unsafe condition 

on these products. 

DATES: We must receive comments on 

this proposed AD by October 30, 2017.

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian AD 

CF–2016–20R1, dated February 3, 2017 

(referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or ‘‘the MCAI’’), to correct an unsafe 

condition for certain Bombardier, Inc., 

Model CL–600–2C10 (Regional Jet 

Series 700, 701, & 702), Model CL–600– 

2D15 (Regional Jet Series 705), Model 

CL–600–2D24 (Regional Jet Series 900), 

and Model CL–600–2E25 (Regional Jet 

Series 1000) airplanes. The MCAI states: 

A CRJ900 aeroplane reported a smoke in 

cabin event due to a non-sustaining electrical 

fire. The source of smoke was traced to a 

burnt heated water supply line behind the #2 

Galley. The surrounding insulation was also 

found burnt. 

The root cause of this electrical fire was an 

electrical short between an un-insulated 

bonding jumper and a terminal block 

carrying 115 volts AC. The circuit resistance 

was high enough and the circuit breakers that 

protect the wiring did not trip open. 

Electrical short of a bonding jumper may 

result in in-flight smoke or fire events as well 

as failure of avionics equipment due to 

possible water spray or leakage from a 

damaged water supply line. The likelihood of 

this happening is increased by the removal 

and installation of the galley or lavatory 

during maintenance, allowing the bonding 

jumper to become wedged under the terminal 

block. 

* * * * * 

Revision 1 of this [Canadian] AD is issued 

to mandate [the installation of protective 

sleeves on the galley and lavatory bonding 

jumper wires in accordance with] 

Bombardier Service Bulletin (SB) 670BA–25– 

101 Revision B dated 12 January 

2017. * * * 

You may examine the MCAI in the

Related Service Information Under 1 

CFR Part 51 

Bombardier, Inc., has issued 

Bombardier Service Bulletin 670BA–25– 

101, Revision B, dated January 12, 2017. 

The service information describes 

procedures for installation of protective 

sleeves on the bonding jumper wires of 

affected galleys and lavatories. This 

service information is reasonably 

available because the interested parties 


jstallworth on DSKBBY8HB2PROD with PROPOSALS
42954 Federal Register / Vol. 82, No. 176 / Wednesday, September 13, 2017 / Proposed Rules 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section. 

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 these same 

type designs. 

Costs of Compliance 

We estimate that this proposed AD 

affects 544 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 

Install protective sleeves ................ 10 work-hours × $85 per hour = 

$850.

Negligible ....................................... $850 $462,400 

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. 

This proposed AD is issued in 

accordance with authority delegated by 

the Executive Director, Aircraft 

Certification Service, as authorized by 

FAA Order 8000.51C. In accordance 

with that order, issuance of ADs is 

normally a function of the Compliance 

and Airworthiness Division, but during 

this transition period, the Executive 

Director has delegated the authority to 

issue ADs applicable to transport 

category airplanes to the Director of the 

System Oversight Division. 

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. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:
