included in a single release on a
company’s Web site, or in any other
forum that is reasonably accessible to
the public.
Each bank or thrift must publish a
summary of its stress tests results
separate from the results of stress tests
conducted at the consolidated level of
its parent holding company, but the
company may include this summary
with its holding company’s public
disclosure. Thus, a bank or thrift with
a parent holding company that is
required to conduct a company-run DFA
stress test under the Federal Reserve
Board’s DFA stress test rules will have
satisfied its public disclosures
requirement when the parent holding
company discloses summary results of
subsidiary’s annual stress test in
satisfaction of the requirements of the
applicable regulations of the company’s
primary Federal regulator, unless the
company’s primary regulator determines
that the disclosures at the holding
company level does not adequately
capture the potential impact of the
scenarios on the capital of the
companies.
A company must disclose, at a
minimum, the following information
regarding the severely adverse scenario:
a. A description of the types of risks
included in the stress test;
b. A summary description of the
methodologies used in the stress
test;
c. Estimates of—
Aggregate losses;
PPNR;
PLLL;
Net income; and
Pro forma regulatory capital ratios and
any other capital ratios specified by
the primary supervisor;
d. An explanation of the most
significant causes for the changes in
regulatory capital ratios; and
e. For bank holding companies and
savings and loan holding
companies: for a stress test
conducted by an insured depository
institution subsidiary of the bank
holding company or savings and
loan holding company pursuant to
section 165(i)(2) of the Dodd-Frank
Act, changes in regulatory capital
ratios and any other capital ratios
specified by the primary Federal
financial regulatory agency of the
depository institution subsidiary
over the planning horizon,
including an explanation of the
most significant causes for the
changes in regulatory capital ratios.
It should be clear in the company’s
public disclosure that the results are
conditioned on the supervisory
scenarios. Items to be publicly disclosed
should follow the same definitions as
those provided in the confidential
report to supervisors. Companies should
disclose all of the required items in a
single public release, as it is difficult to
interpret the quantitative results
without the qualitative supporting
information.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2013–0109,
dated May 22, 2013 (referred to
hereinafter as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
A power loss event was reported on an
aeroplane equipped with a TAE 125–01
engine. The investigation results showed that
the probable cause was contamination of the
engine clutch by coolant spillage during the
last maintenance operation. The
contamination penetrated the clutch housing
through an opening located under the coolant
tank that was only closed by a not fluid-tight
plastic cover.
You may obtain further information by
examining the MCAI in the AD docket.
The design of the engine allows the
crankcase assembly opening to be
susceptible to contamination from
external sources. We are proposing this
AD to prevent in-flight engine power
loss, which could result in loss of
control of, and damage to, the airplane.
Relevant Service Information
Thielert Aircraft Engines GmbH has
issued Service Bulletin (SB) No. TM
TAE 125–0022, dated August 8, 2012.
The SB describes procedures for
applying sealant to close the engine
clutch housing (crankcase assembly)
opening.
FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of Germany, and
is approved for operation in the United
States. Pursuant to our bilateral
agreement with the European
Community, EASA has 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 provided by EASA and
determined the unsafe condition exists
and is likely to exist or develop on other
products of the same type design. This
proposed AD would require applying
PO 00000
Frm 00016
Fmt 4702
Sfmt 4702

sealant to close the engine clutch
housing (crankcase assembly) opening.
Costs of Compliance
We estimate that this proposed AD
affects 140 engines installed on
airplanes of U.S. registry. We also
estimate that it would take about 2.5
hours per engine to comply with this
proposed AD. The average labor rate is
$85 per hour. Required parts cost about
$110 per engine. Based on these figures,
we estimate the cost of the proposed AD
on U.S. operators to be $45,150. Our
cost estimate is exclusive of possible
warranty coverage.
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 to the extent that it justifies
making a regulatory distinction, 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.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2013-0109, dated May 22, 2013 (referred to
hereinafter as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
A power loss event was reported on an aeroplane equipped with a
TAE 125-01 engine. The investigation results showed that the
probable cause was contamination of the engine clutch by coolant
spillage during the last maintenance operation. The contamination
penetrated the clutch housing through an opening located under the
coolant tank that was only closed by a not fluid-tight plastic
cover.
You may obtain further information by examining the MCAI in the AD
docket. The design of the engine allows the crankcase assembly opening
to be susceptible to contamination from external sources. We are
proposing this AD to prevent in-flight engine power loss, which could
result in loss of control of, and damage to, the airplane.
Relevant Service Information
Thielert Aircraft Engines GmbH has issued Service Bulletin (SB) No.
TM TAE 125-0022, dated August 8, 2012. The SB describes procedures for
applying sealant to close the engine clutch housing (crankcase
assembly) opening.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of
Germany, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the European Community, EASA has
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 provided by EASA and determined the unsafe
condition exists and is likely to exist or develop on other products of
the same type design. This proposed AD would require applying sealant
to close the engine clutch housing (crankcase assembly) opening.
Costs of Compliance
We estimate that this proposed AD affects 140 engines installed on
airplanes of U.S. registry. We also estimate that it would take about
2.5 hours per engine to comply with this proposed AD. The average labor
rate is $85 per hour. Required parts cost about $110 per engine. Based
on these figures, we estimate the cost of the proposed AD on U.S.
operators to be $45,150. Our cost estimate is exclusive of possible
warranty coverage.
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 to the extent
that it justifies making a regulatory distinction, 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:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
Thielert Aircraft Engines GmbH: Docket No. FAA-2013-0561;
Directorate Identifier 2013-NE-23-AD.
(a) Comments Due Date
We must receive comments by October 4, 2013.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Thielert Aircraft Engines GmbH TAE 125-01
reciprocating engines.
(d) Reason
This AD was prompted by a report of engine power loss due to
engine coolant contaminating the engine clutch. The design of the
engine allows the crankcase assembly opening to be susceptible to
contamination from external sources. We are issuing this AD to
prevent in-flight engine power loss, which could result in loss of
control of, and damage to, the airplane.
(e) Actions and Compliance
Unless already done, do the following actions.
(1) After the effective date of this AD at the next annual or
100-hour inspection, whichever comes first, apply sealant to close
the engine clutch housing (crankcase assembly) opening.
(2) Thereafter, reapply sealant to the engine clutch housing
(crankcase assembly) opening, whenever the sealant is found to be
not liquid-tight, or is removed.
(3) Guidance on the sealant and application can be found in
Thielert Aircraft Engines GmbH Service Bulletin No.TM TAE 125-0022,
dated August 8, 2012.
(f) Alternative Methods of Compliance (AMOCs)
The Manager, Engine Certification Office, FAA, may approve AMOCs
to this AD. Use the procedures found in 14 CFR 39.19 to make your
request.
