Airworthiness Directives; PILATUS Aircraft Ltd. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
PILATUS Aircraft Ltd. Model PC-7 airplanes. This AD results from 
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 chafing on the wiring harness attached to the engine 
mounting frame on the right-hand side of the engine compartment, which 
could cause a short circuit and could result in a fire in the engine 
compartment. We are issuing this AD to require actions to address the 
unsafe condition on these products.

DATES: This AD is effective November 29, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of November 29, 
2013.

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 http://www.regulations.gov 
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 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 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.
