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 PO 00000 Frm 00021 Fmt 4702 Sfmt 4702 31491 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.

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 Inspection/Modification ..................... 2 work-hours × $85 per hour = $170 ............................ 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.

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 non-conforming 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, 2018.
     Bombardier Service Bulletin 700-26-5003, Revision 01, 
dated February 15, 2018.
     Bombardier Service Bulletin 700-26-6003, Revision 01, 
dated February 15, 2018.
    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 re-connecting incorrectly 
installed connectors to the appropriate mating connectors and an 
operational test of the fire extinguishing system. These documents are 
distinct since they apply

[[Page 31492]]

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
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Inspection/Modification...............  2 work-hours x $85 per               $55            $225         $80,550
                                         hour = $170.
----------------------------------------------------------------------------------------------------------------

    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;

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bombardier, Inc.: Docket No. FAA-2018-0585; Product Identifier 2018-
NM-070-AD.

(a) Comments Due Date

    We must receive comments by August 20, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD-
700-1A11 airplanes, certificated in any category, serial numbers 
9001 through 9839 inclusive, and serial number 9998.

(d) Subject

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

(e) Reason

    This 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. We are issuing this AD 
to address this wiring discrepancy, which, in the event of an engine 
fire, could result in misrouting the supply of fire extinguishing 
agent to the wrong engine, or limit the supply from both FIREX 
bottles to only one engine, which could result in the inability to 
extinguish an engine fire.

(f) Compliance

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

(g) Required Actions

    Within 1,000 flight hours or 15 months, whichever occurs first, 
after the effective date of this AD, perform a visual inspection for 
correct connections between the FIREX squib wire harness connectors 
and FIREX bottle connectors, and install split ring lanyards on the 
FIREX squib wire harness connectors, in accordance with the 
Accomplishment Instructions of the applicable service information 
listed in figure 1 to paragraph (g) of this AD. If any incorrect 
connections are

[[Page 31493]]

found: Before further flight, re-connect the connectors to the 
appropriate mating connecters and do an operational test of the fire 
extinguishing system, in accordance with the Accomplishment 
Instructions of the applicable service information specified in 
figure 1 to paragraph (g) of this AD.
