The MCAI states: Wear and cracks on the stabilizer-trim attachment and relevant structural components have been reported on aeroplanes having accomplished Pilatus Service Bulletin (SB) 53–001 Revision 1, as previously required by FOCA AD HB–2005– 263. Subsequent investigation identified that slightly asymmetric installation and/or operational conditions may result in strong stabilizer vibration, causing crack initiation in the stabilizer-trim attachment fitting or connecting piece. This condition, if not detected and corrected, may lead to a failure of the fitting or connecting piece, possibly resulting in disconnection of the horizontal stabilizer rear attachment, with consequent loss of control of the aeroplane. To address this potential unsafe condition, Pilatus issued SB No. 53–003 (hereafter referred to as ‘the SB’ in this AD) to provide inspection instructions. For the reason described above, this AD requires visual and non destructive inspections of the affected stabilizer-trim attachment components and the related parts and structure to detect cracks, and, depending on findings, the replacement of the affected parts. This AD also provides additional requirements for installation of these parts. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2016–9356. Related Service Information Under 1 CFR Part 51 Pilatus Aircraft Ltd. has issued PC–6 Service Bulletin No. 53–003, Revision 1, dated October 13, 2016. The service information describes procedures for inspecting the stabilizer-trim attachment components and the related parts and structure to detect cracks and replacing all cracked parts. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this AD. 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 PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 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 failure of the stabilizer control system fitting or connecting piece could result in disconnection of the horizontal stabilizer rear attachment, with consequent 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–2016–9356; Directorate Identifier 2016–CE–033– 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 30 products of U.S. registry. We also estimate that it will take about 5 workhours per product to comply with the basic inspection 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 $12,750, or $425 per product. In addition, we estimate that any necessary follow-on replacement actions will take about 6 work-hours and E:\FR\FM\04NOR1.SGM 04NOR1 Federal Register / Vol. 81, No. 214 / Friday, November 4, 2016 / Rules and Regulations require parts costing $2,000, for a cost of $2,510 per product. We have no way of determining the number of products that may need these actions. 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. rmajette on DSK2TPTVN1PROD with RULES 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: VerDate Sep<11>2014 11:51 Nov 03, 2016 Jkt 241001 76847 (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. (e) Reason 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 wear and cracks on the stabilizer-trim attachment and structural components. This condition, if not corrected, could cause failure of the stabilizer control system fitting or connecting piece, which could result in disconnection of the horizontal stabilizer rear attachment with consequent loss of control.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued 
Emergency AD No. 2016-0202-E, dated October 7, 2016 (referred to after 
this as ``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Wear and cracks on the stabilizer-trim attachment and relevant 
structural components have been reported on aeroplanes having 
accomplished Pilatus Service Bulletin (SB) 53-001 Revision 1, as 
previously required by FOCA AD HB-2005-263.
    Subsequent investigation identified that slightly asymmetric 
installation and/or operational conditions may result in strong 
stabilizer vibration, causing crack initiation in the stabilizer-
trim attachment fitting or connecting piece.
    This condition, if not detected and corrected, may lead to a 
failure of the fitting or connecting piece, possibly resulting in 
disconnection of the horizontal stabilizer rear attachment, with 
consequent loss of control of the aeroplane.
    To address this potential unsafe condition, Pilatus issued SB 
No. 53-003 (hereafter referred to as `the SB' in this AD) to provide 
inspection instructions.
    For the reason described above, this AD requires visual and non 
destructive inspections of the affected stabilizer-trim attachment 
components and the related parts and structure to detect cracks, 
and, depending on findings, the replacement of the affected parts. 
This AD also provides additional requirements for installation of 
these parts.

You may examine the MCAI on the Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2016-9356.

Related Service Information Under 1 CFR Part 51

    Pilatus Aircraft Ltd. has issued PC-6 Service Bulletin No. 53-003, 
Revision 1, dated October 13, 2016. The service information describes 
procedures for inspecting the stabilizer-trim attachment components and 
the related parts and structure to detect cracks and replacing all 
cracked parts. This service information is reasonably available because 
the interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section of this 
AD.

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 
failure of the stabilizer control system fitting or connecting piece 
could result in disconnection of the horizontal stabilizer rear 
attachment, with consequent 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-2016-9356; Directorate 
Identifier 2016-CE-033-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 30 products of U.S. registry. 
We also estimate that it will take about 5 work-hours per product to 
comply with the basic inspection 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 $12,750, or $425 per product.
    In addition, we estimate that any necessary follow-on replacement 
actions will take about 6 work-hours and

[[Page 76847]]

require parts costing $2,000, for a cost of $2,510 per product. We have 
no way of determining the number of products that may need these 
actions.

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.

product. The MCAI describes the unsafe condition as wear and cracks 
on the stabilizer-trim attachment and structural components. This 
condition, if not corrected, could cause failure of the stabilizer 
control system fitting or connecting piece, which could result in 
disconnection of the horizontal stabilizer rear attachment with 
consequent loss of control.

(f) Actions and Compliance

    Unless already done, do the following actions.
    (1) For MSN 337 through 1005 and 2001 through 2092: Before 
further flight after November 4, 2016 (the effective date of this 
AD), do a visual inspection of the affected stabilizer-trim 
attachment and structural components following the Accomplishment 
Instructions in Pilatus PC-6 SB No. 53-003, Revision 1, dated

003, Revision 1, dated October 13, 2016, may be installed provided 
it is a serviceable part. For the purpose of this AD, a 
``serviceable part'' is an affected part that is new, or has passed 
an inspection before installation following the Accomplishment 
Instructions in Pilatus PC-6 SB No. 53-003, Revision 1, dated 
October 13, 2016.

(g) Credit for Actions Done Following Previous Service Information

    This AD allows credit for the visual inspection required in 
paragraph (f)(1) of this

[[Page 76848]]

AD if done before November 4, 2016 (the effective date of this AD), 
following Pilatus PC-6 SB No. 53-003, dated October 4, 2016. The 
dye-penetrant or eddy current inspection must still be done 
following Pilatus PC-6 SB No. 53-003, Revision 1, dated October 13, 
2016.

(h) 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
