Federal Aviation Administration Examining the AD Docket This section of the FEDERAL REGISTER contains notices to the public of the proposed issuance of rules and regulations. The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. 14 CFR Part 39 [Docket No. FAA–2010–0583; Directorate Identifier 2010–CE–028–AD] RIN 2120–AA64 Airworthiness Directives; PILATUS AIRCRAFT LTD. Model PC–12/47E Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from 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: cprice-sewell on DSK8KYBLC1PROD with PROPOSALS-1 Reports have been received indicating that, if the power control friction wheel is tightened, the reverse thrust latch may stick and subsequently allow the Power Control Lever (PCL) to be inadvertently retarded aft of the idle detent. This condition, if not corrected, could result in undesired reverse thrust activation which, especially during approach, could result in reduced control of the aeroplane. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI. DATES: We must receive comments on this proposed AD by July 26, 2010. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2010– PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 0093, dated May 20, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Reports have been received indicating that, if the power control friction wheel is tightened, the reverse thrust latch may stick and subsequently allow the Power Control Lever (PCL) to be inadvertently retarded aft of the idle detent. This condition, if not corrected, could result in undesired reverse thrust activation which, especially during approach, could result in reduced control of the aeroplane. For the reason described above, this AD requires an inspection of the PCL reverse thrust latch and the accomplishment of corrective actions as necessary. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information PILATUS AIRCRAFT LTD. has issued Service Bulletin No.: 76–002, dated October 15, 2009. 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 Proposed 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 proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between This Proposed AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are E:\FR\FM\10JNP1.SGM 10JNP1 32864 Federal Register / Vol. 75, No. 111 / Thursday, June 10, 2010 / Proposed Rules highlighted in a Note within the proposed AD. Costs of Compliance We estimate that this proposed AD will affect 80 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $6,800, or $85 per product. In addition, we estimate that any necessary follow-on actions would take about 9 work-hours and require parts costing $100, for a cost of $865 per product. We have no way of determining the number of products that may need these actions. cprice-sewell on DSK8KYBLC1PROD with PROPOSALS-1 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: 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); and 3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities VerDate Mar<15>2010 13:38 Jun 09, 2010 Jkt 220001 under the criteria of the Regulatory Flexibility Act. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

The Proposal This action proposes to amend Title 14 Code of Federal Regulations (14 CFR) part 71 by revising Class E airspace at Unalakleet, AK, to accommodate a new departure procedure, and new and amended SIAPs at Unalakleet Airport. This Class E airspace would provide adequate controlled airspace upward from the surface, and from 700 and 1,200 feet above the surface for the safety and management of IFR operations at Unalakleet Airport. The Class E2 surface areas are published in paragraph 6002 in FAA Order 7400.9T, Airspace Designations and Reporting Points, signed August 27, 2009, and effective September 15, 2009, which is incorporated by reference in 14 CFR 71.1. The Class E airspace areas designated as 700/1200 foot transition areas are published in paragraph 6005 in FAA Order 7400.9T, Airspace Designations and Reporting Points, signed August 27, 2009, and effective September 15, 2009, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document would be subsequently published in the Order. The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore—(1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Because this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities E:\FR\FM\10JNP1.SGM 10JNP1

Airworthiness Directives; PILATUS AIRCRAFT LTD. Model PC-12/47E 
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD results from 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:

    Reports have been received indicating that, if the power control 
friction wheel is tightened, the reverse thrust latch may stick and 
subsequently allow the Power Control Lever (PCL) to be inadvertently 
retarded aft of the idle detent.
    This condition, if not corrected, could result in undesired 
reverse thrust activation which, especially during approach, could 
result in reduced control of the aeroplane.

The proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by July 26, 2010.

ADDRESSES: You may send comments by any of the following methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2010-0583; 
Directorate Identifier 2010-CE-028-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed 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 proposed AD.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2010-0093, dated May 20, 2010 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    Reports have been received indicating that, if the power control 
friction wheel is tightened, the reverse thrust latch may stick and 
subsequently allow the Power Control Lever (PCL) to be inadvertently 
retarded aft of the idle detent.
    This condition, if not corrected, could result in undesired 
reverse thrust activation which, especially during approach, could 
result in reduced control of the aeroplane.
    For the reason described above, this AD requires an inspection 
of the PCL reverse thrust latch and the accomplishment of corrective 
actions as necessary.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    PILATUS AIRCRAFT LTD. has issued Service Bulletin No.: 76-002, 
dated October 15, 2009. 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 Proposed 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 proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed AD and the MCAI or Service 
Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are

[[Page 32864]]

highlighted in a Note within the proposed AD.

Costs of Compliance

    We estimate that this proposed AD will affect 80 products of U.S. 
registry. We also estimate that it would take about 1 work-hour per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $6,800, or $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 9 work-hours and require parts costing $100, for a cost of 
$865 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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); and
    3. 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

numbers (MSN) 1001 and MSN 1003 through 1140, certificated in any 
category.

Subject

    (d) Air Transport Association of America (ATA) Code 76: Engine 
Controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Reports have been received indicating that, if the power control 
friction wheel is tightened, the reverse thrust latch may stick and 
subsequently allow the Power Control Lever (PCL) to be inadvertently 
retarded aft of the idle detent.
    This condition, if not corrected, could result in undesired 
reverse thrust activation which, especially during approach, could 
result in reduced control of the aeroplane.
    For the reason described above, this AD requires an inspection 
of the PCL reverse thrust latch and the accomplishment of corrective 
actions as necessary.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Within 30 days after the effective date of this AD, inspect 
the power control lever reverse thrust latch handle for free 
movement following the accomplishment instructions in paragraph 3.A. 
of PILATUS AIRCRAFT LTD. Service Bulletin No.: 76-002, dated October 
15, 2009.
    (2) If during the inspection required in paragraph (f)(1) of 
this AD you determine the reverse thrust latch sticks or the idle 
detent is not present, do the following actions:
    (i) Before further flight, insert Temporary Revision (TR) No. 12 
to PC-12/47E Pilot's Operating Handbook, dated October 15, 2009, 
into the normal procedures section of the aircraft flight manual 
(AFM).
    (ii) Within 12 months after the effective date of this AD, 
modify the engine control console assembly following the 
accomplishment instructions in paragraph 3.B. of PILATUS AIRCRAFT 
LTD. Service Bulletin No.: 76-002, dated October 15, 2009.
    (iii) Before further flight after the modification required by 
paragraph (f)(2)(ii) of this AD, remove TR No. 12 to PC-12/47E 
Pilot's Operating Handbook, dated October 15, 2009, from the AFM.
    (3) If during the inspection specified in paragraph (f)(1) of 
this AD you determine the reverse thrust latch moves freely and the 
idle detent is present, no further action is required.
