Disclosure of information to the subject of the inquiry could also permit the subject to avoid detection or apprehension. In appropriate circumstances, where compliance would not appear to interfere with or adversely affect the law enforcement purposes of this system and the overall law enforcement process, the applicable exemptions may be waived on a case by case basis. A notice of system of records DHS/ ALL–038 Insider Threat Program System of Records is also published in this issue of the Federal Register. List of Subjects in 6 CFR Part 5 Freedom of information, Privacy. For the reasons stated in the preamble, DHS proposes to amend chapter I of title 6, Code of Federal Regulations, as follows: PART 5—DISCLOSURE OF RECORDS AND INFORMATION 1. The authority citation for part 5 continues to read as follows: ■ Authority: Pub. L. 107–296, 116 Stat. 2135; (6 U.S.C. 101 et seq.); 5 U.S.C. 301. Subpart A also issued under 5 U.S.C. 552. Subpart B also issued under 5 U.S.C. 552a. 2. In appendix C to part 5, add paragraph 74 to read as follows: ■ Appendix C to Part 5—DHS Systems of Records Exempt From the Privacy Act Lhorne on DSK5TPTVN1PROD with PROPOSALS * * * * * 74. The DHS/ALL–038 Insider Threat Program System of Records consists of electronic and paper records and will be used by DHS and its components. The DHS/ALL– 038 Insider Threat Program System of Records System of Records is a repository of information held by DHS in connection with various missions and functions, including, but not limited to the enforcement of civil and criminal laws; investigations, inquiries, and proceedings there under; and national security and intelligence activities. The DHS/ ALL–038 Insider Threat Program System of Records contains information that is collected by, on behalf of, in support of, or in cooperation with DHS and its components and may contain personally identifiable information collected by other Federal, State, local, tribal, foreign, or international government agencies. The Secretary of Homeland Security, pursuant to 5 U.S.C. 552a(j)(2), has exempted this system from the following provisions of the Privacy Act: 5 U.S.C. 552a(c)(3), (c)(4), (d), (e)(1), (e)(2), (e)(3), (e)(4)(G), (e)(4)(H), VerDate Sep<11>2014 16:58 Feb 25, 2016 Jkt 238001 (e)(4)(I), (e)(5), (e)(8), (e)(12), (f), (g)(1), and (h). Additionally, the Secretary of Homeland Security, pursuant to 5 U.S.C. 552a(k)(1), (k)(2), and (k)(5), has exempted this system from the following provisions of the Privacy Act: 5 U.S.C. 552a(c)(3), (d), (e)(1), (e)(4)(G), (e)(4)(H), (e)(4)(I), and (f). Where a record received from another system has been exempted in that source system under 5 U.S.C. 552a(j)(2), DHS will claim the same exemptions for those records that are claimed for the original primary systems of records from which they originated and claims any additional exemptions set forth here. Exemptions from these particular subsections are justified on a case-by-case basis and determined at the time a request is made, for the following reasons: (a) From subsection (c)(3) and (4) (Accounting for Disclosures) because release of the accounting of disclosures could alert the subject of an investigation of an actual or potential criminal, civil, or regulatory violation to the existence of that investigation and reveal investigative interest on the part of DHS and the recipient agency. Disclosure of the accounting would therefore present a serious impediment to law enforcement efforts and/or efforts to preserve national security. Disclosure of the accounting would also permit the subject of a record to impede the investigation, to tamper with witnesses or evidence, and to avoid detection or apprehension, which would undermine the entire investigative process. (b) From subsection (d) (Access to Records) because access to the records contained in this system of records could inform the subject of an investigation of an actual or potential criminal, civil, or regulatory violation to the existence of that investigation and reveal investigative interest on the part of DHS or another agency. Access to the records could permit the subject of a record to impede the investigation, to tamper with witnesses or evidence, and to avoid detection or apprehension. Amendment of the records could interfere with ongoing investigations and law enforcement activities and would impose an unreasonable administrative burden by requiring investigations to be continually reinvestigated. In addition, permitting access and amendment to such information could disclose security-sensitive information that could be detrimental to homeland security. (c) From subsection (e)(1) (Relevancy and Necessity of Information) because in the course of investigations into potential violations of Federal law, the accuracy of information obtained or introduced occasionally may be unclear, or the information may not be strictly relevant or necessary to a specific investigation. In the interests of effective law enforcement, it is appropriate to retain all information that may aid in establishing patterns of unlawful activity. (d) From subsection (e)(2) (Collection of Information from Individuals) because requiring that information be collected from the subject of an investigation would alert the subject to the nature or existence of the investigation, thereby interfering with that investigation and related law enforcement activities. PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 (e) From subsection (e)(3) (Notice to Subjects) because providing such detailed information could impede law enforcement by compromising the existence of a confidential investigation or reveal the identity of witnesses or confidential informants. (f) From subsections (e)(4)(G), (e)(4)(H), and (e)(4)(I) (Agency Requirements) and (f) (Agency Rules), because portions of this system are exempt from the individual access provisions of subsection (d) for the reasons noted above, and therefore DHS is not required to establish requirements, rules, or procedures with respect to such access. Providing notice to individuals with respect to existence of records pertaining to them in the system of records or otherwise setting up procedures pursuant to which individuals may access and view records pertaining to themselves in the system would undermine investigative efforts and reveal the identities of witnesses, and potential witnesses, and confidential informants. (g) From subsection (e)(5) (Collection of Information) because with the collection of information for law enforcement purposes, it is impossible to determine in advance what information is accurate, relevant, timely, and complete. Compliance with subsection (e)(5) would preclude DHS agents from using their investigative training and exercise of good judgment to both conduct and report on investigations. (h) From subsection (e)(8) (Notice on Individuals) because compliance would interfere with DHS’s ability to obtain, serve, and issue subpoenas, warrants, and other law enforcement mechanisms that may be filed under seal and could result in disclosure of investigative techniques, procedures, and evidence. (i) From subsection (g)(1) (Civil Remedies) to the extent that the system is exempt from other specific subsections of the Privacy Act. Dated: February 18, 2016. Karen L.

(Type Certificate Previously Held by Cessna Aircraft Company) Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: E:\FR\FM\26FEP1.SGM 26FEP1 Federal Register / Vol. 81, No. 38 / Friday, February 26, 2016 / Proposed Rules We propose to adopt a new airworthiness directive (AD) for certain Textron Aviation Inc. Model 680 airplanes. This proposed AD was prompted by Cessna’s report of a manufacturing defect which affects the durability of the aft canted bulkhead metallic structure. The manufacturing defect directly affects the bond integrity of the vertical and horizontal stiffeners on the aft canted bulkhead metallic structure. This proposed AD would require repetitive inspections of the aft canted bulkhead, and repair if necessary. This proposed AD would also require a modification, which would terminate the repetitive inspections. We are proposing this AD to prevent disbonding of the horizontal and vertical stiffeners on the aft canted bulkhead. Loss of bond integrity could result in a structural failure that could lead to separation of the cruciform tail and loss of control of the airplane. DATES: We must receive comments on this proposed AD by April 11, 2016. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

SUPPLEMENTARY INFORMATION: The service information describes procedures for a general visual inspection for disbonding and paint cracking around the edges of the stiffeners on the aft canted bulkhead. • Cessna Service Bulletin SB680–53– 08, dated September 28, 2015. The service information describes procedures for modifying the airplane by installing additional stiffeners to the aft canted bulkhead. 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. Comments Invited We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2016–3705; Directorate Identifier 2015– NM–168–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. FAA’s Determination Discussion This proposed AD was prompted by Cessna’s report of a manufacturing defect that affects the durability of the aft canted bulkhead metallic structure. The manufacturing defect directly affects the bond integrity of the vertical and horizontal stiffeners on the aft canted bulkhead metallic structure. This disbonding is caused by a loss of durability in the metal-to-metal bondline, which resulted from a reduced autoclave cure cycle dwell time and temperature during manufacturing. This condition, if not detected and corrected, could result in a structural failure that could lead to separation of the cruciform tail and loss of control of the airplane. Related Service Information Under 1 CFR Part 51 We reviewed the following Cessna service information. • Cessna Service Letter SL680–53–05, Revision 2, dated September 30, 2015. PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between this Proposed AD and the Service Information.’’ Differences Between This Proposed AD and the Service Information Although Cessna Service Letter SL680–53–05, Revision 2, dated September 30, 2015, specifies reporting the inspection results to Cessna, this proposed AD would not require those actions. Although Cessna Service Letter SL680–53–05, Revision 2, dated September 30, 2015, specifies that operators may contact the manufacturer for disposition of certain conditions, this proposed AD would require operators to repair those conditions in accordance with a method approved by the FAA. Although Cessna Service Letter SL680–53–05, Revision 2, dated September 30, 2015; and Service Bulletin SB680–53–08, dated September 28, 2015; use the term ‘‘debond’’ to describe full or partial separation of a stiffener from the aft canted bulkhead structure, this proposed AD instead uses the term ‘‘disbond.’’ Costs of Compliance We estimate that this proposed AD affects 123 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: E:\FR\FM\26FEP1.SGM 26FEP1 9792 Federal Register / Vol. 81, No. 38 / Friday, February 26, 2016 / Proposed Rules ESTIMATED COSTS Action Labor cost Inspection ...................... 1 work-hour × $85 per hour = $85 per inspection cycle. 180 work-hours × $85 per hour = $15,300 ........ Modification ................... We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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. Lhorne on DSK5TPTVN1PROD with PROPOSALS 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 VerDate Sep<11>2014 13:20 Feb 25, 2016 Jkt 238001 Parts cost Cost per product $0 3,190 Cost on U.S. operators $85 per inspection cycle. $18,490 ........................ $10,455 per inspection cycle. $2,274,270. (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.

ACTION: Proposed rule. AGENCY: The Environmental Protection Agency (EPA) is proposing to approve the limited maintenance plan submitted on January 4, 2016, by the State of Washington for the Spokane area, which includes the cities of Spokane, Spokane Valley, Millwood and surrounding unincorporated areas in Spokane County, Washington. This plan addresses the second 10-year maintenance period for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10). A limited maintenance plan is used to meet Clean Air Act requirements for formerly designated nonattainment areas that meet certain qualification criteria. The EPA is proposing to determine Washington’s submittal meets the limited maintenance plan criteria. The Spokane area currently has monitored PM10 levels well below the National Ambient Air Quality Standards (NAAQS) and levels have not increased since the area was redesignated to attainment in 2005. The EPA is also proposing to approve minor updates to the Spokane Regional Clean Air Agency (SRCAA) regulations controlling PM10 related to the maintenance plan.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

[[Page 9791]]

SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Textron Aviation Inc. Model 680 airplanes. This proposed AD was
prompted by Cessna's report of a manufacturing defect which affects the
durability of the aft canted bulkhead metallic structure. The
manufacturing defect directly affects the bond integrity of the
vertical and horizontal stiffeners on the aft canted bulkhead metallic
structure. This proposed AD would require repetitive inspections of the
aft canted bulkhead, and repair if necessary. This proposed AD would
also require a modification, which would terminate the repetitive
inspections. We are proposing this AD to prevent disbonding of the
horizontal and vertical stiffeners on the aft canted bulkhead. Loss of
bond integrity could result in a structural failure that could lead to
separation of the cruciform tail and loss of control of the airplane.

DATES: We must receive comments on this proposed AD by April 11, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion

This proposed AD was prompted by Cessna's report of a manufacturing
defect that affects the durability of the aft canted bulkhead metallic
structure. The manufacturing defect directly affects the bond integrity
of the vertical and horizontal stiffeners on the aft canted bulkhead
metallic structure. This disbonding is caused by a loss of durability
in the metal-to-metal bondline, which resulted from a reduced autoclave
cure cycle dwell time and temperature during manufacturing. This
condition, if not detected and corrected, could result in a structural
failure that could lead to separation of the cruciform tail and loss of
control of the airplane.

Related Service Information Under 1 CFR Part 51

We reviewed the following Cessna service information.
Cessna Service Letter SL680-53-05, Revision 2, dated
September 30, 2015. The service information describes procedures for a
general visual inspection for disbonding and paint cracking around the
edges of the stiffeners on the aft canted bulkhead.
Cessna Service Bulletin SB680-53-08, dated September 28,
2015. The service information describes procedures for modifying the
airplane by installing additional stiffeners to the aft canted
bulkhead.
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.

FAA's Determination

We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

This proposed AD would require accomplishing the actions specified
in the service information described previously, except as discussed
under ``Differences Between this Proposed AD and the Service
Information.''

Differences Between This Proposed AD and the Service Information

Although Cessna Service Letter SL680-53-05, Revision 2, dated
September 30, 2015, specifies reporting the inspection results to
Cessna, this proposed AD would not require those actions.
Although Cessna Service Letter SL680-53-05, Revision 2, dated
September 30, 2015, specifies that operators may contact the
manufacturer for disposition of certain conditions, this proposed AD
would require operators to repair those conditions in accordance with a
method approved by the FAA.
Although Cessna Service Letter SL680-53-05, Revision 2, dated
September 30, 2015; and Service Bulletin SB680-53-08, dated September
28, 2015; use the term ``debond'' to describe full or partial
separation of a stiffener from the aft canted bulkhead structure, this
proposed AD instead uses the term ``disbond.''

Costs of Compliance

We estimate that this proposed AD affects 123 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:

[[Page 9792]]

Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Inspection..................... 1 work-hour x $85 per $0 $85 per inspection $10,455 per
hour = $85 per cycle. inspection cycle.
inspection cycle.
Modification................... 180 work-hours x $85 3,190 $18,490........... $2,274,270.
per hour = $15,300.
----------------------------------------------------------------------------------------------------------------

We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this proposed
AD.
According to the manufacturer, some of the costs of this proposed
AD may be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.

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.
