2018-22-08 BOMBARDIER, INC.: Amendment 39-19481; Docket No. FAA-2018-0585; Product Identifier 2018-NM-070-AD.
(a) EFFECTIVE DATE

    This AD is effective December 10, 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 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.

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 BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published in the
Federal Register on July 6, 2018 (83 FR 31491). The NPRM 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. The NPRM proposed to 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 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.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD 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, 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.

Comments

We gave the public the opportunity to participate in developing
this final rule. The following presents the comments received on the
NPRM and the FAA's response to each comment.

Request To Refer to Revised Service Information

Bombardier requested that the NPRM be updated to reference the
current revision of certain service information to avoid issuing an
Alternate Means of Compliance (AMOC) following the release of this AD.
Bombardier noted that four service bulletins referred to in the NPRM
have been revised. Bombardier stated that the latest revisions correct
a minor error in the original weight and balance section. Bombardier
also noted that a previous revision to the service information included
mention of the Canadian AD CF-2018-08R1, as well as a clarifying note
in the close-out instruction of the service information for operator
convenience and ease of use.
We agree with the commenter's request. Because the revised service
information does not include any additional actions, we have updated
the preamble and figure 1 to paragraph (g) of this AD to refer to the
revised service information.
Bombardier also requested that we revise the NPRM to include
previous revisions of the service information as credit for operators
who have already accomplished the required actions to avoid issuance of
AMOCs following the release of this AD.
We agree with the commenter's request. Because the previous
revisions of the service information do not include any additional
actions, we have revised paragraph (h) of this AD to provide credit for
actions accomplished prior to the effective date of this AD using the
applicable Bombardier service information identified in paragraphs
(h)(1) through (h)(12) of this AD.

Conclusion

We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this final rule with the changes described previously and minor
editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.

Related Service Information Under 1 CFR Part 51


Bombardier, Inc. issued the following service information:
Bombardier Service Bulletin 700-1A11-26-004, Revision 03,
dated August 24, 2018.
Bombardier Service Bulletin 700-26-011, Revision 03, dated
August 24, 2018.
Bombardier Service Bulletin 700-26-5003, Revision 03,
dated August 24, 2018.
Bombardier Service Bulletin 700-26-6003, Revision 03,
dated August 24, 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 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 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.

Costs of Compliance

We estimate that this AD affects 358 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
Inspection/Modification 2 work-hours x $85 per hour = $170
$55
$225
$80,550

According to the manufacturer, some or all of the costs of this 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 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 and associated appliances to the
Director of the System Oversight Division.

Regulatory Findings

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.
