Airworthiness Directives; Stemme GmbH & Co. KG Powered Sailplanes
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 all
Stemme GmbH & Co. KG Models S10, S10-V, and S10-VT powered sailplanes.
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 unapproved rubber
hoses installed in the engine fuel, oil, and cooling systems, which
could lead to a system leak and result in an engine fire. 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 AD
No. 2012-0154, dated August 17, 2012 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
An occurrence has been reported of an engine fire during ground
run of a S10-VT powered sailplane. The investigation results
indicated that an unapproved fuel hose was installed in the engine
fuel system of that aeroplane. Subsequent survey of some N-
registered S 10 aeroplanes revealed more cases of installation of
unapproved fuel, oil and cooling hoses on sailplanes engine systems.
This condition, if not detected and corrected, could lead to a
system leak with subsequent engine fire, possibly resulting in
damage to the sailplane and/or injury of occupants.
Prompted by these findings, Stemme GmbH developed a procedure
for identification of these hoses, to have them removed from
service.
For the reasons described above, this AD requires a one-time
review of the sailplane's maintenance records to determine whether a
serviceable engine hose kit for fuel, oil and cooling systems has
been installed and, depending on findings, replacement of the
affected hoses with serviceable parts.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Stemme F & D has issued Installation Instruction A34-10-093-01,
dated August 13, 2012; and Installation Instruction A34-10-093-02,
dated August 13, 2012. 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 63 products of U.S.
registry. We also estimate that it would take about .5 work-hour per
product to comply with the basic requirements of this proposed AD. The
average labor rate is $85 per work-hour.
Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $2,677.50, or $42.50 per product.
In addition, we estimate that any necessary follow-on actions would
take about 8 work-hours and require parts costing $1,957, for a cost of
$2,637 per product for Models S10 and S10-V. We also estimate that any
necessary follow-on actions would take about 16 work-hours and require
parts costing $1,311, for a cost of $2,671 per product for Model S10-
VT. We have no way of determining the number of products that may need
these actions.
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.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
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:
Stemme GmbH & Co. KG: Docket No. FAA-2012-0982; Directorate
Identifier 2012-CE-035-AD.
(a) Comments Due Date
We must receive comments by November 2, 2012.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Stemme GmbH & Co. KG Models S10, S10-V, and
S10-VT powered sailplanes, all serial numbers, certificated in any
category.
(d) Subject
Air Transport Association of America (ATA) Code 71: Powerplant.
(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 unapproved
rubber hoses installed in the engine fuel, oil, and cooling systems.
We are issuing this proposed AD to prevent a system leak, which
could lead to an engine fire.
(f) Actions and Compliance
Unless already done, do the following actions:
(1) If, on the effective date of this AD, the date of
manufacture of the sailplane is less than five years old, before
further flight after the effective date of this AD, review the
sailplane's maintenance records/logbook for evidence as to whether
the engine fuel, oil, and cooling systems rubber hoses have been
replaced since new. Based on this review, if:
(i) There is no logbook evidence, i.e. logbook entry, that the
engine fuel, oil, and cooling systems rubber hoses have been
replaced since new, before further flight, make a logbook entry
showing compliance with this AD.
(ii) There is logbook evidence, i.e. logbook entry, that the
engine fuel, oil, and/or cooling systems rubber hoses have been
replaced since new, before further flight, review the sailplane's
maintenance records/logbook for current documentation of hose
conformity through a Declaration of Conformity (DoC) or a European
Aviation Safety Agency (EASA) Form 1.
(A) If you can find current documentation of a DoC or an EASA
Form 1, before further flight, make a logbook entry showing
compliance with this AD.
(B) If you cannot find current documentation of a DoC or an EASA
Form 1, before further flight, replace the affected hose(s) with
FAA-approved serviceable hoses following Stemme F & D Installation
Instruction A34-10-093- 01, dated August 13, 2012; or Stemme F & D
Installation Instruction A34-10-093- 02, dated August 13, 2012, as
applicable.
(2) If, on the effective date of this AD, the date of
manufacture of the sailplane is five years old or older, before
further flight after the effective date of this AD, review the
sailplane's maintenance records/logbook for evidence of the date the
engine fuel, oil, and cooling systems rubber hoses were last
replaced and for documentation of hose conformity through a DoC or a
EASA Form 1. Based on this review, if:
(i) There is logbook evidence, i.e. logbook entry, that the
installed engine fuel, oil, and cooling systems rubber hoses are
less than five years old and there is current documentation of hose
conformity with a DoC or an EASA Form 1, before further flight, make
a logbook entry showing compliance with this AD.
(ii) There is logbook evidence, i.e. logbook entry, that the
installed engine fuel, oil, and cooling systems rubber hoses are
less than five years old, but there is no current documentation of
hose conformity with a DoC or an EASA Form 1, before further flight,
replace the affected hoses with FAA-approved serviceable hoses
following Stemme F & D Installation Instruction A34-10-093- 01,
dated August 13, 2012; or Stemme F & D Installation Instruction A34-
10-093- 02, dated August 13, 2012, as applicable.
(iii) There is logbook evidence, i.e. logbook entry, that the
installed engine fuel, oil, and cooling systems rubber hoses are
over five years, before further flight, replace the hoses with FAA-
approved serviceable hoses following Stemme F & D Installation
Instruction A34-10-093- 01, dated August 13, 2012; or Stemme F & D
Installation Instruction A34-10-093- 02, dated August 13, 2012, as
applicable.
(3) As of the effective date of this AD, only install FAA-
approved serviceable engine fuel, oil, and cooling systems rubber
hoses following Stemme F & D Installation Instruction A34-10-093-
01, dated August 13, 2012; or Stemme F & D Installation Instruction
A34-10-093- 02, dated August 13, 2012, as applicable, and that have
a current documentation of hose conformity, i.e., DoC or EASA Form
1.
