ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for DG Flugzeugbau GmbH Model DG–500MB gliders that are equipped with a Solo 2625 02 engine modified with a fuel injection system following the instructions of Solo Kleinmotoren GmbH Technische Mitteilung (TM)/ Service Bulletin (SB) 4600–3 ‘‘Fuel Injection System’’ and identified as Solo 2625 02i. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 possible in-flight engine shut-down and engine fire due to failure of the connecting stud for the two fuel injector mounts of the engine redundancy system. We are issuing this AD to require actions to address the unsafe condition on these products. DATES: This AD is effective May 26, 2017. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of May 26, 2017. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0051; or in person at Document Management Facility, U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC 20590.

SUPPLEMENTARY INFORMATION: We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to DG Flugzeugbau GmbH Model DG–500MB gliders. The NPRM was published in the Federal Register on February 7, 2017 (82 FR 9535). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI states: 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. The MCAI can be found in the AD docket on the Internet at: https:// www.regulations.gov/ document?D=FAA-2017-0051-0002. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM 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 E:\FR\FM\21APR1.SGM 21APR1 Federal Register / Vol. 82, No. 76 / Friday, April 21, 2017 / Rules and Regulations changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 We reviewed Solo Kleinmotoren GmbH 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 the AD. nlaroche on DSK30NT082PROD with RULES Costs of Compliance We estimate that this 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 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 this 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 AD will not have federalism implications under VerDate Sep<11>2014 13:51 Apr 20, 2017 Jkt 241001 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.

Airworthiness Directives; DG Flugzeugbau GmbH

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for DG 
Flugzeugbau GmbH Model DG-500MB gliders that are equipped with a Solo 
2625 02 engine modified with a fuel injection system following the 
instructions of Solo Kleinmotoren GmbH Technische Mitteilung (TM)/
Service Bulletin (SB) 4600-3 ``Fuel Injection System'' and identified 
as Solo 2625 02i. This AD results from mandatory continuing 
airworthiness information (MCAI) issued 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 possible 
in-flight engine shut-down and engine fire due to failure of the 
connecting stud for the two fuel injector mounts of the engine 
redundancy system. We are issuing this AD to require actions to address 
the unsafe condition on these products.

DATES: This AD is effective May 26, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of May 26, 2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to DG Flugzeugbau GmbH Model 
DG-500MB gliders. The NPRM was published in the Federal Register on 
February 7, 2017 (82 FR 9535). The NPRM proposed to correct an unsafe 
condition for the specified products and was based on mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country. The MCAI states:

    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.

    The MCAI can be found in the AD docket on the Internet at: https://www.regulations.gov/document?D=FAA-2017-0051-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM 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

[[Page 18695]]

changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Solo Kleinmotoren GmbH 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 the AD.

Costs of Compliance

    We estimate that this 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 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 this 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 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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

1. The authority citation for part 39 continues to read as follows:

    Authority: 9 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

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

2017-08-09 DG Flugzeugbau GmbH: Amendment 39-18858; Docket No. FAA-
2017-0051; Directorate Identifier 2016-CE-043-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective May 26, 
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 May 26, 2017 
(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 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
