Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted 
by reports of interior emergency lights remaining ``ON'' following 
routine operational checks of the emergency light system. This AD 
requires changing the wiring gauge for the affected emergency lights 
power supplies wiring to prevent overheating in the wires. We are 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective May 1, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 1, 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 August 30, 2016 (81 FR 59539). The NPRM was prompted by 
reports of interior emergency lights remaining ``ON'' following routine 
operational checks of the emergency light system. The NPRM proposed to 
require changing the wiring gauge for the affected emergency lights 
power supplies wiring to prevent overheating in the wires. Overheating 
can damage the wire insulation, potentially causing a fire.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-12, effective May 11, 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:

    There have been several reports of Interior Emergency Lights 
remaining ``ON'' following routine operational checks of the 
Emergency Light System. During these events, the system could not be 
deactivated and the associated circuit breaker was also found 
tripped. The events were caused by the overheating of the negative 
interlock and ground wires at the Emergency Light System Power 
Supplies.
    Investigation has determined that the wire gauge of the negative 
interlock and ground wiring is incompatible with the current load 
experienced during the Emergency Light System operational check and 
this has led to the degradation of the wiring insulation.
    This [Canadian] AD is being issued to mandate the change of the 
wiring gauge from 22 to 20 American wire gauge (AWG) for the 
affected Emergency Lights Power Supplies wiring.

    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-2016-
9054.

Comments

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

Support for the NPRM

    The Air Line Pilots Association, International, stated that it 
supports the NPRM.

Requests To Refer to Updated Service Information and Provide Credit for 
Previous Service Information

    Horizon Air and Ryota Takeuchi requested that we revise the NPRM to 
specify that the wire gauge be changed in accordance with the 
Accomplishment Instructions of Bombardier Service Bulletin 84-33-12, 
Revision B, dated June 28, 2016 (``SB 84-33-12, Revision B'').
    Horizon Air also requested that we revise the NPRM to provide 
credit for previous actions done using Bombardier Service Bulletin 84-
33-12, Revision A, dated January 19, 2016.
    We agree with these requests. We have determined that SB 84-33-12, 
Revision B, requires no additional actions for airplanes modified using 
previous revisions. Therefore, we have revised this final rule to refer 
to SB 84-33-12, Revision B. We have also revised paragraph (h) of this 
AD to include credit for actions accomplished before the effective date 
of this AD using Bombardier Service Bulletin 84-33-12, Revision A, 
dated January 19, 2016.

Request To Reference Only the Actions Required for Compliance

    Horizon Air also requested that we revise paragraph (g) of the 
proposed AD to require that the wire gauge be changed in accordance 
with paragraph 3.B. of the Accomplishment Instructions of SB 84-33-12, 
Revision B. Horizon pointed out that incorporating the Job Set-up and 
Close Out sections of the Accomplishment Instructions restricts an 
operator's ability to perform other maintenance in conjunction with the 
requirements of the proposed AD.
    We agree with Horizon Air's request for the reason provided. We 
have revised this AD to reference only the actions necessary to address 
the unsafe condition specified in this AD.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD 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 correcting 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 AD.

Related Service Information Under 1 CFR Part 51

    We reviewed SB 84-33-12, Revision B. This service information 
describes procedures for changing the wiring gauge for the affected 
emergency lights power supplies wiring to prevent overheating in the 
wires. 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 52 airplanes of U.S. registry.
    We estimate the following costs to comply with this 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.

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.
