We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 airplanes. This proposed 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 proposed AD would require, for certain airplanes, replacing the DC generator control units (GCUs) with new GCUs and replacing the GCU label. We are proposing 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), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, 
-311, and -315 airplanes. This proposed 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 proposed AD would 
require, for certain airplanes, replacing the DC generator control 
units (GCUs) with new GCUs and replacing the GCU label. We are 
proposing 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: We must receive comments on this proposed AD by August 10, 2015.

Discussion

    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 by searching for and locating Docket No. FAA-2015-
1985.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service bulletins.
     Service Bulletin 8-24-84, Revision D, dated April 10, 
2014. This service information describes incorporating Bombardier 
modification summary (ModSum) 8Q101710 by replacing the

[[Page 36494]]

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. This service information 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 
NPRM.

FAA's Determination and Requirements of This Proposed AD

    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 pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 92 airplanes of U.S. 
registry.
    We also estimate that it would take about 3 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost up to 
$12,098 per product. Based on these figures, we estimate the cost of 
this proposed 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 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.

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

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]
