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.

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;
    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.
