SUPPLEMENTARY INFORMATION:
Discussion
The Federal Office of Civil Aviation (FOCA), which is the aviation
authority for Switzerland, has issued AD HB-2013-009, dated October 7,
2013 (referred to after this as ``the MCAI''), to correct an unsafe
condition for the specified products. The MCAI states:
This Airworthiness Directive (AD) is prompted due to a report of
chafing of the wiring harness attached to the engine mounting frame
on the RH side of the engine compartment. Due to the limited space
available in this area the wiring harness can chafe against the RH
flexible duct for the condenser.
Such a condition, if left uncorrected, could lead to a short
circuit which could cause a fire in the engine compartment.
In order to correct and control the situation, this AD requires
a one-time inspection of the wiring harness and flexible duct of the
condenser for chafing. If major damage is found, the damaged parts
must be replaced. If minor damage is found, this AD requires the
installation of a protective sleeve on the wiring harness.
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 it in Docket No. FAA-2013-0928.
Relevant Service Information
PILATUS Aircraft Ltd. has issued PILATUS PC-7 Service Bulletin No.
24-009, dated September 6, 2013. The actions described in this service
information are intended to correct the unsafe condition identified in
the MCAI.
FAA's Determination and Requirements of This 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.
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
chafing of the wiring harness in the engine compartment could cause a
short circuit and could result in a fire in the engine compartment.
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-2013-0928; Directorate
Identifier 2013-CE-036-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 <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 10 products of U.S. registry.
We also estimate that it will take about 1 work-hour 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 $850, or $85 per product.
In addition, we estimate that necessary follow-on actions will take
about 5 work-hours to install a protective sleeve on the wiring
harness, if minor damage is found, and require parts costing
approximately $100, for a cost of $525 per product. We also estimate
that it will take about 12 work-hours to replace damaged parts, if
major damage is found, and require parts costing approximately $500,
for a cost of $1,520 per product. We have no way of determining the
number of products that may 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),
[[Page 67013]]
(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.
