We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model DHC-8-400 series airplanes. This AD was prompted by the failure of the fire control amplifier, which was likely caused by an electrical short in a discharged squib for a fire extinguishing bottle. This proposed AD would require replacing certain circuit breakers. We are proposing this AD to address the unsafe condition on these products.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-25, dated September 5, 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 
Service Bulletin] SB 84-26-16 to prevent the inadvertent discharge 
of fire extinguishing bottles; [leaving the flight crew with less 
firefighting capability in the event of a real 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.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier 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.

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 53 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

----------------------------------------------------------------------------------------------------------------

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.

[[Page 25556]]

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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bombardier, Inc.: Docket No. FAA-2017-0518; Directorate Identifier 
2016-NM-167-AD.

(a) Comments Due Date

    We must receive comments by July 17, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc., Model DHC-8-400, -401, and

and 4003 through 4504 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 26, Fire 
Protection.

(e) Reason

    This AD was prompted 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. We are issuing 
this AD to prevent failure of the FCA and subsequent discharge of 
fire extinguishing bottles and false fire indications, leaving the 
flightcrew with less firefighting capability in the event of a real 
fire.

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Replacement of Affected Circuit Breakers

    Within 6,000 flight hours or 3 years, whichever occurs first, 
after the effective date of this AD: Replace the 7.5-amp circuit 
breakers specified in Bombardier Service Bulletin 84-26-16, Revision 
A, dated February 12, 2016, with 1-amp circuit breakers, part number 
MS3320-1, in accordance with the Accomplishment Instructions of 
Bombardier Service Bulletin 84-26-16, Revision A, dated February 12, 
2016.
