14 CFR Part 39

[Docket No. FAA-2013-0835; Directorate Identifier 2013-NM-095-AD; 
Amendment 39-17790; AD 2014-05-17]
RIN 2120-AA64

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 results from fuel system 
reviews conducted by the manufacturer. This AD requires accomplishing 
modifications to the fuel system. We are issuing this AD to prevent the 
potential of ignition sources inside fuel tanks, which, in combination 
with flammable fuel vapors, could result in fuel tank explosions and 
consequent loss of the airplane.

DATES: This AD becomes effective May 2, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of May 2, 2014.

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 October 2, 
2013 (78 FR 60800). The NPRM was prompted by results from fuel system 
reviews conducted by the manufacturer. The NPRM proposed to require 
accomplishing modifications to the fuel system. We are issuing this AD 
to prevent the potential of ignition sources inside fuel tanks, which, 
in combination with flammable fuel vapors, could result in fuel tank 
explosions and consequent loss of the airplane.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-07, dated March 1, 2013 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for the specified products. The MCAI states:

    Bombardier Aerospace has completed a system safety review of the 
aeroplane fuel system against fuel tank safety standards * * *. The 
identified non-compliances were then assessed * * * to determine if 
mandatory corrective action is required.
    The assessment showed that a number of modifications to the fuel 
system are required to mitigate unsafe conditions that could result 
in potential ignition sources within the fuel system.
* * * * *

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-0835-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 60800, October 2, 
2013) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant 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 (78 FR 60800, October 2, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 60800, October 2, 2013).

Costs of Compliance

    We estimate that this AD affects 94 airplanes of U.S. registry.
    We also estimate that it will take about 519 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $58,924 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $9,685,666, or $103,039 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-2013-0835; 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.
