Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD No.: 2014–0269, dated December 11, 2014 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: E:\FR\FM\07FEP1.SGM 07FEP1 9536 Federal Register / Vol. 82, No. 24 / Tuesday, February 7, 2017 / Proposed Rules An occurrence was reported involving a failure of the connecting stud for the two fuel injector mounts of the engine redundancy system. This condition, if not corrected, could lead to an uncommanded in-flight engine shutdown and engine fire, possibly resulting in loss of control of the aeroplane. To address this unsafe condition, Solo Kleinmotoren GmbH issued SB/TM 4600–5 to provide instructions for reinforcement and securing of the injector mounts. For the reason described above, this AD requires modification of the engine redundancy system. Solo Kleinmotoren GmbH SB/TM 4600–3 (currently at issue 2, dated 03 December 2012) will be revised to incorporate the modification required by SB/TM 4600–5 for future Solo 2625 02i engines. You may examine the MCAI on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2017–0051. Related Service Information Under 1 CFR Part 51 Solo Kleinmotoren GmbH has issued Technische Mitteilung (English translation: Service Bulletin), Nr. 4600– 5, Ausgabe 2 (English translation: Issue 2), dated December 12, 2014. The service information describes procedures for changing the fuel injector mounts of the engine redundancy system and securing the connection of the lower to the upper mount. 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. Lhorne on DSK30JT082PROD with PROPOSALS Costs of Compliance We estimate that this proposed AD will affect 3 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $67 per product. VerDate Sep<11>2014 13:37 Feb 06, 2017 Jkt 241001 Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $456, or $152 per product. 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. 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: PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 PART 39—AIRWORTHINESS DIRECTIVES 1.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD No.: 2014-0269, dated December 11, 2014 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:


[[Page 9536]]


    An occurrence was reported involving a failure of the connecting 
stud for the two fuel injector mounts of the engine redundancy 
system.
    This condition, if not corrected, could lead to an uncommanded 
in-flight engine shut-down and engine fire, possibly resulting in 
loss of control of the aeroplane.
    To address this unsafe condition, Solo Kleinmotoren GmbH issued 
SB/TM 4600-5 to provide instructions for reinforcement and securing 
of the injector mounts.
    For the reason described above, this AD requires modification of 
the engine redundancy system.
    Solo Kleinmotoren GmbH SB/TM 4600-3 (currently at issue 2, dated 
03 December 2012) will be revised to incorporate the modification 
required by SB/TM 4600-5 for future Solo 2625 02i engines.

    You may examine the MCAI on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0051.

Related Service Information Under 1 CFR Part 51

    Solo Kleinmotoren GmbH has issued Technische Mitteilung (English 
translation: Service Bulletin), Nr. 4600-5, Ausgabe 2 (English 
translation: Issue 2), dated December 12, 2014. The service information 
describes procedures for changing the fuel injector mounts of the 
engine redundancy system and securing the connection of the lower to 
the upper mount. 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 3 products of U.S. 
registry. We also estimate that it would take about 1 work-hour per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $67 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $456, or $152 per product.

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.

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]

2. The FAA amends Sec.  39.13 by adding the following new AD:

DG Flugzeugbau GmbH: Docket No. FAA-2017-0051; Directorate 
Identifier 2016-CE-043-AD.

(a) Comments Due Date

    We must receive comments by March 24, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to DG Flugzeugbau GmbH DG-500MB gliders, all 
serial numbers, that are:
    (1) Equipped with a Solo 2625 02 engine modified with a fuel 
injection system following the instructions of Solo Kleinmotoren 
GmbH Service Bulletin (SB)/Technische Mitteilung (TM) 4600-3 ``Fuel 
Injection System'') and identified as Solo 2625 02i; 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 failure of the 
connecting stud for the two fuel injector mounts of the engine 
redundancy system on gliders equipped with a Solo 2625 02i engine. 
We are issuing this AD to prevent such failure that could lead to 
the potential of an in-flight shut-down and engine fire and result 
in loss of control.

(f) Actions and Compliance

    Unless already done, within the next 60 days after the effective 
date of this AD, modify the engine redundancy system following the 
actions in Solo Kleinmotoren GmbH Technische Mitteilung (English 
translation: Service Bulletin), Nr. 4600-5, Ausgabe 2 (English 
translation: Issue 2), dated December 12, 2014.

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

(g) Credit for Actions Accomplished in Accordance With Previous Service 
Information

    This AD allows credit for modification of the engine redundancy 
system as required in

[[Page 9537]]

paragraph (f) of this AD if done before the effective date of this 
AD following Solo Kleinmotoren GmbH Technische Mitteilung (English 
translation: Service Bulletin), Nr. 4600-5, Ausgabe 1 (English 
translation: Issue 1), dated November 24, 2014.

(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
