SUPPLEMENTARY INFORMATION:

Discussion

    Transport Canada, which is the aviation authority for Canada, has 
issued AD No. CF-2014-14, dated June 5, 2014 (referred to after this as 
``the MCAI''), to correct an unsafe condition for Viking Air Limited 
Model DHC-3 airplanes. The MCAI states:

    A horizontal stabilizer actuator (trim jack) mounting block, 
part number C3FS79-5, was found loose in the forward-aft and side-
to-side directions. The trim jack mounting block fastens the 
stabilizer actuator (trim jack) which allows the angle of incidence 
of the stabilizer to be varied. The stabilizer actuator (trim jack) 
also functions as the rear mounting point for the stabilizer.
    Failure of the mounting block through breakage or detachment may 
cause loss of control of the horizontal stabilizer and subsequent 
loss of control of the aeroplane. Therefore, this AD mandates a one-
time inspection of the stabilizer actuator (trim jack) mounting 
block.

    You may examine the MCAI on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2014-
0616.

Relevant Service Information

    Viking Air Limited has issued Viking Service Bulletin No. V3/0005, 
Revision `A', dated May 27, 2014. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

FAA's Determination and Requirements of the 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 this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are issuing this AD because we 
evaluated all information provided by the State of Design Authority and 
determined the unsafe condition exists and is likely to exist or 
develop on other products of the same type design.

Interim Action

    We consider this AD interim action. After the State of Design 
reviews and evaluates the reporting data, we may take further 
rulemaking action in the future.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
failure of the mounting block through breakage or detachment may cause 
loss of control of horizontal stabilizer and subsequent loss of 
control. Therefore, we determined that notice and opportunity for 
public comment before issuing this AD are impracticable and that good 
cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2014-0616; Directorate 
Identifier 2014-CE-018-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may

[[Page 51089]]

amend this AD because of those comments.
    We will post all comments we receive, without change, to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD will affect 35 products 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 AD. The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $8,925, or $255 per product.
    The scope of damage found in the inspections could vary from 
airplane to airplane. We have no way of determining how much damage may 
be found on each airplane or the cost to repair or replace damaged 
parts on each airplane or the number of airplanes that may require 
repair or replacements.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information 
Collection Clearance Officer, AES-200.

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.

    Unless already done, do the following actions in paragraphs 
(f)(1) and (f)(2).
    (1) Within the next 100 hours time-in-service after September 
16, 2014 (the effective date of this AD) or within the next 90 days 
after September 16, 2014 (the effective date of the this AD), 
whichever occurs first, inspect the horizontal stabilizer actuator 
(trim jack) for movement or defects following the Accomplishment 
Instructions in Viking Service Bulletin No. V3/0005, Revision `A', 
dated May 27, 2014.
    (2) If any movement or defects are found during the inspection 
required by paragraph (f)(1) of this AD, before further flight, you 
must contact Viking Air Limited to obtain FAA-approved repair 
instructions approved specifically for compliance with this AD and 
incorporate those instructions. You can find contact information for 
Viking Air Limited in paragraph (i)(3) of this AD. Use the Service
