Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for all
Stemme GmbH & Co. KG Models S10, S10-V, and S10-VT powered sailplanes.
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 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 AD to require
actions to address the unsafe condition on these products.
DATES: This AD is effective January 7, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of January 7,
2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on September 18, 2012
(77 FR 57531). That NPRM proposed 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.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (77 FR 57531, September
18, 2012) 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:
<bullet> Are consistent with the intent that was proposed in the
NPRM (77 FR 57531, September 18, 2012) for correcting the unsafe
condition; and
[[Page 71488]]
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 57531, September 18, 2012).
Costs of Compliance
We estimate that this AD will affect 63 products of U.S. registry.
We also estimate that it will take about .5 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour.
Based on these figures, we estimate the cost of this 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 will
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 will 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 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.
Examining the AD Docket
You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a>; 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.

(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 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 January 7, 2013 (the effective date of this AD), the
date of manufacture of the sailplane is less than five years old,
before further flight after January 7, 2013 (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 maintenance records/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 maintenance records/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 January 7, 2013 (the effective date of this AD), the
date of manufacture of the sailplane is five years old or older,
before further flight after January 7, 2013 (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 maintenance records/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 maintenance records/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
