DEPARTMENT OF TRANSPORTATION (a) Payment pursuant to a qualifying levy or criminal restitution order will be made 30 days after the TSP decision letter. (b) In no case will payment exceed the participant’s calculated entitlement. (c) The entire amount of a restitution order or levy entitlement must be disbursed at one time. A series of payments will not be made. A payment pursuant to a restitution order or levy extinguishes all rights to any further payment under that order or levy, even if the entire amount of the entitlement cannot be paid. Any further award must be contained in a separate restitution order or levy. (d) If a participant has funds in more than one type of account, payment will be made from each account in the following order, until the amount of the levy or restitution order is reached: (1) Civilian account; (2) Uniformed services account; (3) Beneficiary participant account. (e) Payment will be made pro rata from the participant’s traditional and Roth balances. The distribution from the traditional balance will be further prorated between the tax-deferred balance and tax-exempt balance. The payment from the Roth balance will be further pro-rated between contributions in the Roth balance and earnings in the Roth balance. In addition, all payments will be distributed pro rata from all TSP Funds in which the participant’s account is invested. All pro-rated amounts will be based on the balances in each fund or source of contributions on the day the disbursement is made. (f) The payment is taxable to the participant and is subject to ten percent Federal income tax withholding. The tax withholding will be taken from the payee’s entitlement and the gross amount of the payment (i.e., the net payment distributed to the payee plus the amount withheld from the payment for taxes) will be reported to the IRS as income to the participant. (g) A properly paid levy or restitution order cannot be returned to the TSP.

Discussion On October 24, 2013, we issued AD 2013–22–14, Amendment 39–17646 (78 FR 65869, November 4, 2013) (‘‘AD 2013–22–14’’). That AD required actions intended to address an unsafe condition on any DG Flugzeugbau GmbH Model DG–1000T glider equipped with a Solo Kleinmotoren Model 2350 C engine and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. Since we issued AD 2013–22–14, the manufacturer of the Solo Kleinmotoren E:\FR\FM\27JNP1.SGM 27JNP1 Federal Register / Vol. 79, No. 124 / Friday, June 27, 2014 / Proposed Rules Model 2350 C engine has developed an engine modification to restore engine operation. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2013– 0217R1, dated May 5, 2014 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: An occurrence of Solo 2350 C engine shaft failure and consequent propeller detachment was reported. The preliminary investigation revealed that the failed shaft was earlier modified in accordance with an approved method. This condition, if not corrected, could lead to additional cases of release of the propeller from the engine, possibly resulting in damage to the sailplane, or injury to persons on the ground. To address this potential unsafe condition, EASA issued Emergency AD 2013–0217–E to prohibit operation of the engine. Since that AD was issued, Solo Kleinmotoren GmbH developed a modification consisting of installing an improved eccenter axle-pulley assembly, allowing to resume operation of the engine. For the reason described above, this AD is revised to incorporate the optional modification, cancelling the operational restriction. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2013–0929. Relevant Service Information Solo Kleinmotoren GmbH issued Technische Mitteilung Service Bulletin Nr. 4603–14, dated April 28, 2014. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. wreier-aviles on DSK5TPTVN1PROD with PROPOSALS 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 2 products of U.S. registry. We also estimate that it would take about .5 work-hour per product to VerDate Mar<15>2010 13:54 Jun 26, 2014 Jkt 232001 comply with the proposed retained requirement of placing a copy of AD 2013–22–14 into the Limitations section of the aircraft flight manual, which prohibits engine operation. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this proposed retained requirement on U.S. operators to be $85, or $42.50 per product. In addition, we estimate that the optional engine modification would take about 1.5 work-hours and require parts costing $100, for a cost of $227.50. If both products of U.S. registry incorporated the engine modification, the cost of the proposed modification on U.S. operators would be $455. If the engine modification is done, it would also take about .5 work-hour per product to remove the engine operation restriction (copy of AD 2013–22–14) from the Limitations section of the aircraft flight manual. The average labor rate is $85 per work-hour, for a cost of $42.50 per product. 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. 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. PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 36441 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.

Federal Aviation Administration (FAA), DOT. ACTION: Proposed rule; withdrawal. AGENCY: This document withdraws a notice of proposed rulemaking (NPRM) that would have applied to certain Piper Aircraft, Inc. Models PA–28–140, PA– 28–150, PA–28–160, PA–28–180, PA– 28R–180, and PA–28R–200 airplanes. The proposed airworthiness directive (AD) would have superseded AD 71– 21–08, Amendment 39–1312, which currently requires replacement of the fuel selector valve cover. This proposed AD would have added additional airplanes to the AD’s applicability section and changed the compliance time of the required actions. Since issuance of the NPRM, the FAA has reevaluated this airworthiness concern and determined that an unsafe condition does not exist that would warrant AD action. This withdrawal does not prevent the FAA from initiating future rulemaking on this subject. SUMMARY: As of June 27, 2014, the proposed rule published August 20, 2013 (78 FR 51121), is withdrawn.

FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to Piper Aircraft, Inc. Models PA– 28–140, PA–28–150, PA–28–160, PA– 28–180, PA–28R–180, and PA–28R–200 airplanes. That NPRM published in the Federal Register on August 20, 2013 (78 FR 51121). That NPRM proposed to supersede AD 71–21–08, Amendment 39–1312 (36 FR 19572, October 8, 1971), by adding airplanes to and changing the compliance time of AD 71–21–08 fuel selector valve cover replacement requirements. Because of the comments received on the NPRM (78 FR 51121, August 20, 2013), the FAA re-evaluated the data collected on the safety concern and concluded that: • There was evidence of pilot inexperience and an absence of fuel selector valve maintenance (in accordance with Piper Service Bulletin 355, dated June 5, 1972) in the Piper PA–28–180 crash of December 28, 2011; and • The low frequency of PA–28 series safety events due to the inadvertent selection of the ‘‘OFF’’ position of fuel selector valves, since AD 71–21–08 was published on October 13, 1971, does not warrant AD action. To mitigate the safety concern from recurring, the FAA may take other airworthiness action such as a special airworthiness information bulletin (SAIB) to recommend the actions contained in the proposed rule and capture the concerns identified by the public during the NPRM (78 FR 51121, August 20, 2013) comment period. Withdrawal of this NPRM (78 FR 51121, August 20, 2013) constitutes only such action and does not preclude the agency from issuing future rulemaking on this issue, nor does it commit the agency to any course of action in the future. Regulatory Findings Since this action only withdraws an NPRM, it is neither a proposed nor a final rule and therefore, is not covered under Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979).

Discussion

    On October 24, 2013, we issued AD 2013-22-14, Amendment 39-17646 
(78 FR 65869, November 4, 2013) (``AD 2013-22-14''). That AD required 
actions intended to address an unsafe condition on any DG Flugzeugbau 
GmbH Model DG-1000T glider equipped with a Solo Kleinmotoren Model 2350 
C engine and was based on mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country.
    Since we issued AD 2013-22-14, the manufacturer of the Solo 
Kleinmotoren

[[Page 36441]]

Model 2350 C engine has developed an engine modification to restore 
engine operation.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2013-0217R1, dated May 5, 2014 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    An occurrence of Solo 2350 C engine shaft failure and consequent 
propeller detachment was reported. The preliminary investigation 
revealed that the failed shaft was earlier modified in accordance 
with an approved method.
    This condition, if not corrected, could lead to additional cases 
of release of the propeller from the engine, possibly resulting in 
damage to the sailplane, or injury to persons on the ground.
    To address this potential unsafe condition, EASA issued 
Emergency AD 2013-0217-E to prohibit operation of the engine.
    Since that AD was issued, Solo Kleinmotoren GmbH developed a 
modification consisting of installing an improved eccenter axle-
pulley assembly, allowing to resume operation of the engine.
    For the reason described above, this AD is revised to 
incorporate the optional modification, cancelling the operational 
restriction.

You may examine the MCAI on the Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2013-0929.

Relevant Service Information

    Solo Kleinmotoren GmbH issued Technische Mitteilung Service 
Bulletin Nr. 4603-14, dated April 28, 2014. 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.

Costs of Compliance

    We estimate that this proposed AD will affect 2 products of U.S. 
registry. We also estimate that it would take about .5 work-hour per 
product to comply with the proposed retained requirement of placing a 
copy of AD 2013-22-14 into the Limitations section of the aircraft 
flight manual, which prohibits engine operation. The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of this proposed 
retained requirement on U.S. operators to be $85, or $42.50 per 
product.
    In addition, we estimate that the optional engine modification 
would take about 1.5 work-hours and require parts costing $100, for a 
cost of $227.50. If both products of U.S. registry incorporated the 
engine modification, the cost of the proposed modification on U.S. 
operators would be $455.
    If the engine modification is done, it would also take about .5 
work-hour per product to remove the engine operation restriction (copy 
of AD 2013-22-14) from the Limitations section of the aircraft flight 
manual. The average labor rate is $85 per work-hour, for a cost of 
$42.50 per product.
    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.

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.

2. Amend Sec.  39.13 by removing Amendment 39-17646 (78 FR 65869, 
November 4, 2013), and adding the following new AD:

DG Flugzeugbau GmbH: Docket No. FAA-2013-0929; Directorate 
Identifier 2013-CE-031-AD.

(a) Comments Due Date

    We must receive comments by August 11, 2014.

(b) Affected ADs

    This AD revises AD 2013-22-14, Amendment 39-17646 (78 FR 65869, 
November 4, 2013) (``AD 2013-22-14'').

(c) Applicability

    This AD applies to DG Flugzeugbau GmbH Model DG-1000T gliders, 
all serial numbers, that are:
    (1) Equipped with a Solo Kleinmotoren Model 2350 C engine; and
    (2) certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 72: Engine.

(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 engine shaft 
failure and consequent propeller detachment. We are issuing this AD 
to

[[Page 36442]]

prevent engine shaft failure and propeller detachment, which could 
result in damage to the glider and injury to persons on the ground.

 (f) Actions and Compliance

    Unless already done, do the following actions in paragraphs 
(f)(1) through (f)(4) of this AD.
    (1) As of November 25, 2013 (the effective date retained from AD 
2013-22-14), do not operate the engine unless the engine is modified 
following instructions that are approved by the FAA specifically for 
AD 2013-22-14. Contact the FAA office identified in paragraph (g)(1) 
of this AD to get more information about obtaining such 
instructions.
    (2) As of November 25, 2013 (the effective date retained from AD 
2013-22-14), place a copy of AD 2013-22-14 or this AD into the 
Limitations section of the aircraft flight manual (AFM).
    (3) To remove the prohibited engine operation requirement in 
paragraph (f)(1) of this AD, modify the engine as specified in the 
Actions paragraph of Solo Kleinmotoren GmbH Technische Mitteilung 
Service Bulletin Nr. 4603-14, dated April 28, 2014, unless already 
modified with FAA-approved instructions as specified in paragraph 
(f)(1) of this AD.

    Note 1 to paragraph (f)(3) of this AD: This service information 
contains German to English translation. The European Aviation Safety 
Agency (EASA) used the English translation in referencing the 
document. For enforceability purposes, we will refer to the Solo 
Kleinmotoren GmbH service information as the title appears on the 
document.

    (4) Prior to further flight after modifying the engine as 
specified in paragraph (f)(1) or paragraph (f)(3) of this AD, remove 
the engine operation restriction (copy of AD 2013-22-14) from the 
Limitations section of the AFM.
