Airworthiness Directives; DG Flugzeugbau GmbH
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt 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 Service Bulletin (SB)/Technische
Mitteilung (TM) 4600-3 ``Fuel Injection System'') and identified as
Solo 2625 02i. This proposed AD results from 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 the
potential of an in-flight shut-down and engine fire due to 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 proposed AD to require actions to address the unsafe
condition on these products.

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 http://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.
