We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 airplanes. This AD was prompted by reports of un-annunciated failures of the direct current (DC) starter generator, which caused caution indicators of the affected systems to illuminate and prompted emergency descents and landings. This AD requires replacing the DC generator control units (GCUs) with new GCUs and replacing the GCU label. We are issuing this AD to prevent a low voltage condition on the left main DC bus, which, during critical phases of flight, could result in the loss of flight management, navigation, and transponder systems, and could affect continued safe flight.

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-8-102, -103, -106, -201, -202, -301, -311, 
and -315 airplanes. This AD was prompted by reports of un-annunciated 
failures of the direct current (DC) starter generator, which caused 
caution indicators of the affected systems to illuminate and prompted 
emergency descents and landings. This AD requires replacing the DC 
generator control units (GCUs) with new GCUs and replacing the GCU 
label. We are issuing this AD to prevent a low voltage condition on the 
left main DC bus, which, during critical phases of flight, could result 
in the loss of flight management, navigation, and transponder systems, 
and could affect continued safe flight.

DATES: This AD becomes effective November 24, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 24, 
2015.

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-8-102, -103, -106, -201, -202, -301, -311, and -315 
airplanes. The NPRM published in the Federal Register on June 25, 2015 
(80 FR 36493).
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-31R2, dated November 11, 2014 (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-
102, -103, -106, -201, -202, -301, -311, and -315 airplanes. The MCAI 
states:

    Four occurrences of un-annunciated failure of the No. 1 Direct 
Current (DC) Starter Generator prompted emergency descents and 
landings resulting from the illumination of numerous caution 
indications of the affected systems. The functionality of the 
affected systems such as Flight Management System, Navigation, and 
transponder systems, were reportedly reduced or lost. Investigation 
determined the failure was a result of a low voltage condition of 
the Left Main DC Bus. During critical phases of flight, the loss of 
these systems could affect continued safe flight.
    The original issue of this [Canadian] AD mandated the 
modification [replacing certain DC GCUs with new GCUs and replacing 
labels] which introduces generator control unit (GCU) undervoltage 
protection.
    Revision 1 of this [Canadian] AD added a GCU part number to the 
applicability of Part III of this [Canadian] AD, in order to ensure 
that all units are fitted with a warning label.
    Revision 2 of this [Canadian] AD corrects the GCU part number in 
the applicability of Part III of this [Canadian] AD.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-1985-0003.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 36493, June 25, 
2015) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed, except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 36493, June 25, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 36493, June 25, 2015).

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information.
     Service Bulletin 8-24-84, Revision D, dated April 10, 
2014, describes incorporating Bombardier Modification Summary (ModSum) 
8Q101710 by replacing the GCU with a new GCU, and replacing the GCU 
label for airplanes having certain Phoenix DC power GCU part numbers.
     Service Bulletin 8-24-89, Revision C, dated November 4, 
2014, describes incorporating Bombardier ModSum 8Q101925 by replacing 
the GCU with a new GCU, and replacing the GCU label for airplanes 
having certain Goodrich DC power GCU part numbers.
    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 of this 
AD.

Costs of Compliance

    We estimate that this AD affects 92 airplanes of U.S. registry.
    We also estimate that it takes about 3 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour.

[[Page 63421]]

Required parts will cost up to $12,098 per product. Based on these 
figures, we estimate the cost of this AD on U.S. operators to be up to 
$1,136,476, or up to $12,353 per product.

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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2015-1985; or in person at the 
Docket Management Facility between 9 a.m. and 5 p.m., Monday through 
Friday, except Federal holidays. The AD docket contains this AD, the 
regulatory evaluation, any comments received, and other information.

2015-1985; Directorate Identifier 2014-NM-214-AD.

(a) Effective Date

    This AD becomes effective November 24, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. Model DHC-8-102, -103, -106,

indicators of the affected systems to illuminate and prompted 
emergency descents and landings. We are issuing this AD to prevent a 
low voltage condition on the left main DC bus which, during critical
