We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, and -106 airplanes; and Model DHC-8-200 and -300 series airplanes. This AD was prompted by a report of heat damage found on a nacelle firewall after an unsuccessful engine ground start and several events of heat damage found on direct current starter/generator terminal block assemblies. This AD requires an inspection to detect damage on the nacelle firewalls and the terminal block assemblies and to make sure the insulating sleeves are installed and have no damage, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.

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, and -106 airplanes; and Model DHC-8-200 and -300 
series airplanes. The NPRM published in the Federal Register on April 
12, 2016 (81 FR 21495) (``the NPRM'').
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-03R1, dated July 24, 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, 
and -106 airplanes; and Model DHC-8-200 and -300 series airplanes. The 
MCAI states:

    There has been one in-service report of heat damage on a nacelle 
firewall found after an unsuccessful engine ground start. There have 
also been several reports of heat damage found on Direct Current 
Starter/Generator terminal block assemblies, part number (P/N) 
82450075-001.
    The investigation determined that in all cases, the heat damage 
was caused by arcing between the firewall and terminal blocks with 
missing insulating sleeves on the conductive bushings. The 
insulating sleeves may have been inadvertently omitted during the 
incorporation of Modsum 8/1926, or during the installation of 
terminal blocks P/N 82450075-001.
    Arcing with the firewall becomes an ignition source, creating a 
potential fire hazard when combined with a fuel or hydraulic fluid 
leak.
    The original issue of this [Canadian] AD mandated the [detailed 
visual] inspection [for damage to the nacelle firewalls and to make 
sure the insulating sleeves are installed and have no damage] and 
rectification [corrective actions such as installing or replacing 
insulating sleeves, or replacing a terminal block], as required, of 
the nacelle firewall and terminal block assembly P/N 82450075-001 
installed with Modsum 8/1926.
    Revision 1 of this [Canadian] AD is issued to revise the 
Applicability to ensure that the terminal blocks have the insulating 
sleeves installed.

    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-
5044.

Comments

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

Request To Reduce the Compliance Time

    The Air Line Pilots Association, International requested that, due 
to the nature of the AD, the proposed 14-month compliance time be 
reduced to 10 months.
    We do not agree to reduce the compliance time. The 14-month 
compliance time was developed by TCCA in coordination with Bombardier, 
Inc., and we concur that it is an appropriate compliance time. However, 
if we receive data to justify a shorter compliance time, we may 
consider further rulemaking on this issue. We have not changed this AD 
in this regard.

Conclusion

    We reviewed the relevant data, considered the comment received, 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 for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 8-24-92, Revision A, dated 
April 11, 2014. The service information describes procedures for an 
inspection to detect damage on the nacelle firewalls and the terminal 
block assemblies and to make sure the insulating sleeves are installed 
and have no damage, and corrective action. 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 75 airplanes of U.S. registry.
    We also estimate that it will take about 2 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $12,750, or $170 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 1 work-hour and require parts costing $551, for a cost of 
$636 per product. We have no way of determining the number of aircraft 
that might need these actions.

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.
