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 BD–700–1A10 

and BD–700–1A11 airplanes. This 

proposed AD was prompted by reports 

that non-conforming FIREX squib wire 

harness connectors may have been 

installed, which could result in FIREX 

squib wire harness connectors being 

connected to the wrong FIREX bottle 

connectors on affected aircraft. This 

proposed AD would require a visual 

inspection of the connections between 

the FIREX squib wire harness 

connectors and FIREX bottle connectors, 

installation of split ring lanyards on the 

FIREX squib wire harness connectors, 

and corrective actions 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 August 20, 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–2018–08R1, 

dated March 2, 2018 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc., Model BD– 

700–1A10 and BD–700–1A11 airplanes. 

The MCAI states: 

Bombardier, Inc., has been made aware 

that non-conforming squib connector wire 

harnesses may have been installed on one of 

the two engine FIREX bottle installations on 

some of the affected aeroplanes. The subject 

non conformity of squib connector wire 

length can allow cross connection between 

the two squib connectors on one of the 

engine FIREX bottles, preventing proper 

function of the engine FIREX system. 

In the event of an engine fire, this wiring 

discrepancy may potentially misroute the 

supply of fire extinguishing agent to the 

wrong engine, or limit the supply from both 

FIREX bottles to only one engine, [and could 

result in the inability to extinguish an engine 

fire,] hence impacting the operational safety 

of the aeroplane. 

Bombardier, Inc., issued service bulletins 

(SB) 700–26–011, 700–26–5003, 700–26– 

6003, and 700–1A11–26–004, for the affected 

model aeroplanes, to address the potentially 

unsafe condition caused by the nonconforming FIREX bottle squib connector 

wiring. 

The original version of this [Canadian] AD 

was issued to mandate compliance with the 

above-mentioned SBs, as applicable. 

Revision 1 of this [Canadian] AD is issued 

to correct an error in the applicability section 

of the original AD. 

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–2018– 

0585. 

Related Service Information Under 1 

CFR Part 51 

We reviewed the following service 

information: 

• Bombardier Service Bulletin 700– 

1A11–26–004, Revision 01, dated 

February 15, 2018. 

• Bombardier Service Bulletin 700– 

26–011, Revision 01, dated February 15,

This service information describes 

procedures for a visual inspection of the 

connections between the FIREX squib 

wire harness connectors and the FIREX 

bottle connectors to determine whether 

the connectors are installed correctly, 

and installation of split ring lanyards on 

the FIREX squib wire harness 

connectors. This service information 

also describes procedures for reconnecting incorrectly installed 

connectors to the appropriate mating 

connectors and an operational test of the 

fire extinguishing system. These 

documents are distinct since they apply 


daltland on DSKBBV9HB2PROD with PROPOSALS

to different airplane models in different 

configurations. This service information 

is reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section. 

FAA’s Determination 

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 the 

relevant information and determined 

the unsafe condition described 

previously is likely to exist or develop 

on other products of the same type 

designs. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously. 

Costs of Compliance 

We estimate that this proposed AD 

affects 358 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 

Inspection/Modification ..................... 2 work-hours × $85 per hour = $170 ............................ $55 $225 $80,550 

According to the manufacturer, some 

or all 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 known 

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. 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt an 

airworthiness directive (AD) for certain 

Bombardier, Inc., Model DHC–8–102, 

–103, and –106 airplanes, Model DHC– 

8–200 series airplanes, and Model DHC– 

8–300 series airplanes. This proposed 

AD was prompted by reports of arcing 

and smoke emanating from the 

windshield, caused by loose or damaged 

windshield heater terminal lugs. This 

proposed AD would require revising the 

maintenance or inspection program to 

incorporate maintenance review board 

(MRB) tasks for general visual 

inspections of the windshield moisture 

seal. This proposed AD would also 

require re-torqueing the windshield 

heater terminal lugs, applying a coating 

to the windshield heater screw heads, 

doing a chemical cleaning of the wiring 

and components, doing a visual 

inspection of the wiring and 

components, doing an operational test 

of the pilot’s and co-pilot’s windshield 

heating system, and repair if necessary.
