2014-17-01 VIKING AIR LIMITED: Amendment 39-17954; Docket No. FAA-2014-0616; Directorate Identifier 2014-CE-018-AD.
(a) EFFECTIVE DATE

    This  airworthiness  directive (AD)  becomes  effective  September 16,
    2014.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This AD  applies  to  Viking Air  Limited Models DHC-3 airplanes,  all
    serial numbers, certificated in any category.

(d) SUBJECT

    Air Transport Association of America (ATA) Code 55: Stabilizers.

(e) REASON

    This AD was prompted by mandatory continuing airworthiness information
    (MCAI) issued by the aviation authority of another country to identify
    and  correct an  unsafe condition  on  an  aviation product.  The MCAI
    describes  the  unsafe  condition  as  looseness  of  the   horizontal
    stabilizer actuator mounting block in the forward-aft and side-to-side
    directions. We are issuing this  AD to prevent breakage or  detachment
    of the horizontal stabilizer actuator mounting block, which could lead
    to  failure  of  the horizontal  stabilizer  with  subsequent loss  of
    control.

(f) ACTIONS AND COMPLIANCE

    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

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 http://www.regulations.gov
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 amend this AD because of
those comments.
We will post all comments we receive, without change, to http://www.
regulations.gov, 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.
