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: wreier-aviles on DSK5TPTVN1PROD with RULES 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 https://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 VerDate Mar<15>2010 15:17 Nov 07, 2013 Jkt 232001 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 https:// 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. PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 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 workhour 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 workhours 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), E:\FR\FM\08NOR1.SGM 08NOR1 Federal Register / Vol. 78, No. 217 / Friday, November 8, 2013 / Rules and Regulations (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.

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 https://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 https://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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

     Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2013-22-13 PILATUS Aircraft Ltd.: Amendment 39-17645; Docket No. 
FAA-2013-0928; Directorate Identifier 2013-CE-036-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective November 29, 
2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to PILATUS Aircraft Ltd. Model PC-7 airplanes, 
manufacturers' serial numbers (MSN) 101 through 618, certificated in 
any category.

(d) Subject

    Air Transport Association of America (ATA) Code 24: Electrical 
Power.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated by an 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. We are issuing this AD to 
prevent a short circuit, which could result in fire in the engine 
compartment.

 (f) Actions and Compliance

    Unless already done, do the actions specified in paragraphs 
(f)(1) and (f)(2) of this AD.
    (1) Within the next 90 days after November 29, 2013 (the 
effective date of this AD), visually inspect the wiring harness and 
the flexile duct in the engine compartment for signs of chafing 
following the Accomplishment Instructions in PILATUS Aircraft Ltd. 
PC-7 Service Bulletin No. 24-009, dated September 6, 2013.
    (2) If, during the inspection required in paragraph (f)(1) of 
this AD, any signs of chafing are found, before further flight, take 
all necessary corrective actions following the Accomplishment 
Instructions in PILATUS Aircraft Ltd. PC-7 Service Bulletin No. 24-
009, dated September 6, 2013.

(g) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Standards Office, FAA, has the authority to approve AMOCs for this 
AD, if requested using the procedures found in 14 CFR 39.19. Send 
information to ATTN: Doug Rudolph, Aerospace Engineer, FAA, Small 
Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 
64106; telephone: (816) 329-4059; fax: (816) 329-4090; email: 
doug.rudolph@faa.gov. Before using any approved AMOC on any airplane 
to which the AMOC applies, notify your appropriate principal 
inspector (PI) in the FAA Flight Standards District Office (FSDO), 
or lacking a PI, your local FSDO.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, a federal agency may not conduct or sponsor, and a person 
is not required to respond to, nor shall a person be subject to a 
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 OMB Control Number for this information collection is 
2120-0056. Public reporting for this collection of information is 
estimated to be approximately 5 minutes per response, including the 
time for reviewing instructions, completing and reviewing the
