Airworthiness Directives; Bombardier,

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), 

CL–600–2D15 (Regional Jet Series 705), 

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

and CL–600–2E25 (Regional Jet Series 

1000) airplanes. This proposed AD was 

prompted by several incidents of 

electrical shorting and sparks caused by 

de-icing fluid leaks between flight deck 

windshields and side windows. This 

proposed AD would require water spray 

tests and general visual inspections for 

water in the flight compartment, and 

water removal and sealant application if 

necessary. We are proposing this AD to 

address the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by January 2, 2018. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2017–28, 

dated August 23, 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), CL–600–2D15 (Regional Jet 

Series 705), CL–600–2D24 (Regional Jet 

Series 900), and CL–600–2E25 (Regional 

Jet Series 1000) airplanes. The MCAI 

states: 

Several incidents of electrical shorting and 

sparks have been reported in the cockpit of 

CL–600–2C10 and CL–600–2D24 aeroplanes. 

De-icing fluid can leak between the 

windshields and side windows, leading to 

possible damage to the cockpit floodlight 

wires and electrical connections. If not 

corrected, this condition may result in a 

flight compartment fire. 

This [Canadian] AD is issued to mandate 

a water spray test and [general visual] 

inspection for evidence of fluid ingress into 

the flight compartment. It also provides 

mandatory instructions for sealant 

application if required. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2017– 

1025. 

Related Service Information Under 1 

CFR Part 51 

Bombardier, Inc., has issued Service 

Bulletin 670BA–56–003, Revision A, 

dated April 13, 2016. This service 

information describes procedures for 

doing water spray tests on the flight 

deck windows, doing general visual 

inspections for water in the flight 

compartment, removing water, and 

applying sealant to the flight deck 

windows. This service information is 

reasonably available because the 

interested parties have access to it 

through their normal course of business 


rmajette on DSKBCKNHB2PROD with PROPOSALS
Federal Register / Vol. 82, No. 221 / Friday, November 17, 2017 / Proposed Rules 54305 

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 543 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 

Spray tests and inspections ............................ 2 work-hours × $85 per hour = $170 ............. $0 $170 $92,310 

We estimate the following costs to do 

any necessary water removal and 

sealant application that would be 

required based on the results of the 

proposed inspection. We have no way of 

determining the number of airplanes 

that might need this water removal and 

sealant application: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Water removal and sealant application ........................ 4 work-hours × $85 per hour = $340 ........................... $308 $648 

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,

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part

issuing this AD to detect and correct de-icing 

fluid entering the flight deck, which could 

damage the flight deck floodlight wires and 

electrical connections, and ultimately could 

lead to a fire in the flight compartment.
