BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 SUPPLEMENTARY INFORMATION: [Docket No. FAA–2013–0929; Directorate Identifier 2013–CE–031–AD; Amendment 39–17968; AD 2013–22–14 R1] Discussion RIN 2120–AA64 rmajette on DSK2TPTVN1PROD with RULES2 Airworthiness Directives; DG Flugzeugbau GmbH Gliders Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are revising an airworthiness directive (AD) 2013–22– SUMMARY: VerDate Mar<15>2010 15:35 Sep 12, 2014 Jkt 232001 We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to add an AD that would apply to DG Flugzeugbau GmbH Model DG– 1000T airplanes. The NPRM was published in the Federal Register on June 27, 2014 (79 FR 36440), and proposed to revise AD 2013–22–14, Amendment 39–17646 (78 FR 65869, November 4, 2013) (‘‘AD 2013–22–14’’). Since we issued AD 2013–22–14, the manufacturer of the Solo Kleinmotoren Model 2350 C engine has developed an PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 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. The MCAI can be found in the AD docket on the Internet at: http:// www.regulations.gov/ #!documentDetail;D=FAA-2013-09290003. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 36440, June 27, 2014) or on the determination of the cost to the public. Conclusion Costs of Compliance We estimate that this AD will affect 2 products of U.S. registry. We also estimate that it will take about .5 workhour per product to comply with the retained requirement of placing a copy of AD 2013–22–14 into the Limitations section of the aircraft flight manual, E:\FR\FM\15SER1.SGM 15SER1 54896 Federal Register / Vol. 79, No. 178 / Monday, September 15, 2014 / Rules and Regulations (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. which prohibits engine operation. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this retained requirement on U.S. operators to be $85, or $42.50 per product. In addition, we estimate that the optional engine modification will 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 modification on U.S. operators will be $455. If the engine modification is done, it will 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 AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. You may examine the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2013– 0929; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647– 5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. Authority for This Rulemaking List of Subjects in 14 CFR Part 39 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.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to add an AD that would apply to DG Flugzeugbau GmbH Model DG-
1000T airplanes. The NPRM was published in the Federal Register on June 
27, 2014 (79 FR 36440), and proposed to revise AD 2013-22-14, Amendment 
39-17646 (78 FR 65869, November 4, 2013) (``AD 2013-22-14'').
    Since we issued AD 2013-22-14, the manufacturer of the Solo 
Kleinmotoren 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.

The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2013-0929-0003.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 36440, June 27, 
2014) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 36440, June 27, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 36440, June 27, 2014).

Costs of Compliance

    We estimate that this AD will affect 2 products of U.S. registry. 
We also estimate that it will take about .5 work-hour per product to 
comply with the retained requirement of placing a copy of AD 2013-22-14 
into the Limitations section of the aircraft flight manual,

[[Page 54896]]

which prohibits engine operation. The average labor rate is $85 per 
work-hour.
    Based on these figures, we estimate the cost of this retained 
requirement on U.S. operators to be $85, or $42.50 per product.
    In addition, we estimate that the optional engine modification will 
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 modification on U.S. operators will be 
$455.
    If the engine modification is done, it will 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 AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected

    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 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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 removing Amendment 39-17646 (78 FR 
65869, November 4, 2013), and adding the following new AD:

2013-22-14 R1 DG Flugzeugbau GmbH: Amendment 39-17968; Docket No. 
FAA-2013-0929; Directorate Identifier 2013-CE-031-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective October 20, 
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 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.

(g) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager,
