ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc., Model DHC–8–400

by the failure of the fire control 

amplifier (FCA), which was likely 

caused by an electrical short in a 

discharged squib for a fire extinguishing 

bottle. This AD requires replacing 

certain circuit breakers. We are issuing 

this AD to address the unsafe condition 

on these products. 

DATES: This AD is effective November 6, 

2017.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Bombardier, Inc., Model 

DHC–8–400 series airplanes. The NPRM 

published in the Federal Register on 

June 2, 2017 (82 FR 25554) (‘‘the 

NPRM’’). The NPRM was prompted by 

the failure of the FCA, which was likely 


jstallworth on DSKBBY8HB2PROD with RULES
45704 Federal Register / Vol. 82, No. 189 / Monday, October 2, 2017 / Rules and Regulations 

caused by an electrical short in a 

discharged squib for a fire extinguishing 

bottle. The NPRM proposed to require 

replacing certain circuit breakers. We 

are issuing this AD to prevent failure of 

the FCA and subsequent discharge of 

fire extinguishing bottles and false fire 

indications, leaving the flight crew with 

reduced firefighting capability in the 

event of a fire. 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2016–25, 

dated August 22, 2016 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc., Model 

DHC–8–400 series airplanes. The MCAI 

states: 

An operator reported having a false 

SMOKE warning light for the Aft Baggage 

compartment, which caused the pilots to 

discharge the Aft Baggage compartment fire 

extinguishing bottles per Aircraft Flight 

Manual procedures. Subsequently, there 

were continuous engine and Auxiliary Power 

Unit (APU) fire warning lights, and the fire 

extinguishing bottles for both engines 

(forward and aft) and the APU were 

automatically discharged. Post event 

investigation of the Fire Control Amplifier 

(FCA) revealed a burnt 2600–P2 connector. 

The FCA was also found to have sustained 

significant thermal damage. In a separate 

event involving a different operator, several 

fire extinguishing bottles discharged after an 

electrical short was introduced into the FCA 

by a shorted squib tester (external ground 

support equipment) during maintenance. 

The FCA manufacturer has identified the 

most likely failure condition to be an 

electrical short at the discharged squib. The 

squib’s burst disk may have caused a short 

circuit of the bridgewires, which caused the 

FCA’s internal power wires to experience 

thermal damage, consequently powering 

other squibs and fire alarm lines and 

resulting in the uncommanded discharge of 

the fire extinguishing bottles and false fire 

indications. 

Bombardier (BA) has issued service 

bulletin (SB) 84–26–16 to change two 7.5 

amp circuit breakers to lower current rating 

1 amp circuit breakers to prevent damage to 

squib discharge circuits and the inadvertent 

discharge of fire extinguishing bottles. 

This [Canadian] AD mandates the 

incorporation of [Bombardier] SB 84–26–16 

to prevent the inadvertent discharge of fire 

extinguishing bottles [leaving the flight crew 

with reduced firefighting capability in the 

event of a fire]. 

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– 

0518. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

Bombardier, Inc., has issued Service 

Bulletin 84–26–16, Revision A, dated 

February 12, 2016. This service 

information describes procedures for 

locating and replacing certain 7.5-amp 

circuit breakers with 1-amp circuit 

breakers. 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. 

Costs of Compliance 

We estimate that this AD affects 53 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement of circuit breakers ..................... 3 work-hours × $85 per hour = $255 ............. $0 $255 $13,515 

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 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 AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

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 that this AD: 

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.

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2009–17– 

01, which applied to certain Gulfstream 

Model G–IV, GIV–X, GV–SP airplanes 

and Model GV airplanes. AD 2009–17– 

01 required an inspection for sealant 

applied to the exterior of the auxiliary 

power unit (APU) enclosure (firewall), 

and a revision of the airplane flight 

manual (AFM), as applicable. This AD 

requires revising the AFM and revising 

the applicability to include additional 

airplanes. This AD was prompted by a 

report indicating that the type design 

sealant applied to the APU enclosure 

failed certain tests. We are issuing this 

AD to address the unsafe condition on 

these products. 

DATES: This AD is effective November 6, 

2017.
