SUPPLEMENTARY INFORMATION: E:\FR\FM\28AUP1.SGM 28AUP1 52216 Federal Register / Vol. 80, No. 167 / Friday, August 28, 2015 / Proposed Rules 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–2015–3642; Directorate Identifier 2015–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:// 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. 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 NPRM. Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2015– 0130, dated July 7, 2015 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: We estimate that this proposed AD will affect 195 products of U.S. registry. We also estimate that it would take about 2 work-hours 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 $33,150, or $170 per product. In addition, we estimate that any necessary follow-on actions would take about 15 to 38 work-hours and require parts costing $250 to $400 depending on the type of repair, for a cost of $2,325 to $4,280 per product. The cost may vary depending on the extent of damage found. We have no way of determining the number of products that may need these actions. During accomplishment of SOCATA Service Bulletin (SB) SB10–152–55 at original issue, some operators reported finding heavy corrosion of the horizontal stabilizer (HS) spar. The results of the technical investigation have identified that the corrosion was caused by humidity ingress in the HS on aeroplanes subject to severe environmental conditions. This condition, if not detected and corrected, could result in buckling and permanent HS distortion, possibly resulting in reduced control of the aeroplane. To address this unsafe condition, SOCATA issued SB 10–152–55 Revision 1 to provide instructions for inspection and corrective action. For the reasons described above, this AD requires repetitive inspections of the affected area of the HS and, depending on findings, accomplishment of applicable corrective action(s). Lhorne on DSK5TPTVN1PROD with PROPOSALS You may examine the MCAI on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2015–3642. Related Service Information Under 1 CFR Part 51 SOCATA has issued DAHER– SOCATA TB Aircraft Mandatory Service Bulletin SB 10–152, Amendment 1, dated April 2015. The service information describes procedures for inspection for corrosion on horizontal stabilizer spar and repair, if necessary. This service information is reasonably VerDate Sep<11>2014 12:57 Aug 27, 2015 Jkt 235001 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. Costs of Compliance 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 PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 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), (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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

The FAA proposes to increase the rates for Enroute and Oceanic overflights based on fiscal year 2013 cost and air traffic activity data. The FAA proposes to phase in this rate increase over three years in equal percentage terms. This is a less burdensome approach than the alternative of phasing in the new rates in equal absolute terms, and is the same methodology used in the previous rulemaking.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2015-0130, dated July 7, 2015 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    During accomplishment of SOCATA Service Bulletin (SB) SB10-152-
55 at original issue, some operators reported finding heavy 
corrosion of the horizontal stabilizer (HS) spar.
    The results of the technical investigation have identified that 
the corrosion was caused by humidity ingress in the HS on aeroplanes 
subject to severe environmental conditions.
    This condition, if not detected and corrected, could result in 
buckling and permanent HS distortion, possibly resulting in reduced 
control of the aeroplane.
    To address this unsafe condition, SOCATA issued SB 10-152-55 
Revision 1 to provide instructions for inspection and corrective 
action.
    For the reasons described above, this AD requires repetitive 
inspections of the affected area of the HS and, depending on 
findings, accomplishment of applicable corrective action(s).

    You may examine the MCAI on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2015-
3642.

Related Service Information Under 1 CFR Part 51

    SOCATA has issued DAHER-SOCATA TB Aircraft Mandatory Service 
Bulletin SB 10-152, Amendment 1, dated April 2015. The service 
information describes procedures for inspection for corrosion on 
horizontal stabilizer spar and repair, if necessary. 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 NPRM.

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.

Costs of Compliance

    We estimate that this proposed AD will affect 195 products of U.S. 
registry. We also estimate that it would take about 2 work-hours 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 $33,150, or $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 15 to 38 work-hours and require parts costing $250 to $400 
depending on the type of repair, for a cost of $2,325 to $4,280 per 
product. The cost may vary depending on the extent of damage found. 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),
    (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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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:

SOCATA: Docket No. FAA-2015-3642; Directorate Identifier 2015-CE-
028-AD.

(a) Comments Due Date

    We must receive comments by October 13, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to SOCATA Models TB 9, TB 10, TB 20, TB 21, and 
TB 200 airplanes, all manufacturer serial numbers, certificated in 
any category.

(d) Subject

    Air Transport Association of America (ATA) Code 55: Stabilizers.

[[Page 52217]]

(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 humidity in the 
horizontal stabilizer on airplanes subject to severe environmental 
conditions. We are issuing this AD to detect and correct corrosion 
of the horizontal stabilizer (HS) spar, which could lead to result 
in buckling and permanent HS distortion, possibly resulting in 
reduced control.

(f) Actions and Compliance

    Unless already done, do the actions in paragraphs (f)(1) through 
(f)(5) of this AD:
    (1) Within 13 months after the effective date of this AD and 
repetitively thereafter at intervals not to exceed 72 months, do a 
special detailed inspection of the HS spar following the 
instructions of DAHER-SOCATA TB Aircraft Mandatory Service Bulletin 
SB 10-152, Amendment 1, dated April 2015.
    (2) If no discrepancy is detected during any inspections 
required by paragraph (f)(1) of this AD, protect the HS spar 
following the instructions of DAHER-SOCATA TB Aircraft Mandatory 
Service Bulletin SB 10-152, Amendment 1, dated April 2015.
    (3) If any discrepancy is detected during any inspection 
required by paragraph (f)(1) of this AD, before further flight, do 
the applicable corrective action(s) following the instructions of 
DAHER-SOCATA TB Aircraft Mandatory Service Bulletin SB 10-152, 
Amendment 1, dated April 2015.
    (4) Accomplishment of protection or corrective actions on an 
airplane as required by paragraph (f)(2) or (f)(3) of this AD, as 
applicable, does not constitute terminating action for the 
repetitive inspections as required by paragraph (f)(1) of this AD 
for that airplane.
    (5) Inspections and corrective actions on an airplane, done 
before the effective date of this AD following the instructions of 
DAHER-SOCATA TB Aircraft Recommended Service Bulletin SB 10-152, 
dated May 2013, are acceptable to comply with the requirements of 
this AD for that airplane. After the effective date of this AD, 
repetitive inspections and applicable corrective actions, as 
required by this AD, must be done as required by paragraph (f)(1) of 
this AD following the instructions of DAHER-SOCATA TB Aircraft 
Mandatory Service Bulletin SB 10-152, Amendment 1, dated April 2015.

(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: Albert Mercado, Aerospace Engineer, FAA, Small 
Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 
64106; telephone: (816) 329-4119; fax: (816) 329-4090; email: 
albert.mercado@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.
