Germany. We are issuing this AD to
prevent the universal bearing of the
lower rudder mounting from slipping
out of the bearing support. The
universal bearing slipping out could
result in the rudder separating from its
support. This failure could lead to loss
of sailplane control during flight
operations.
DATES: This AD becomes effective on
March 15, 2006.
As of March 15, 2006, the Director of
the Federal Register approved the
incorporation by reference of certain
publications listed in the regulation.

SUPPLEMENTARY INFORMATION:
Glaser-Dirks Flugzeugbau GmbH Models
DG–100 and DG–400 sailplanes and
certain DG Flugzeugbau GmbH Models
DG–500 Elan Series and DG–500M
sailplanes. The LBA reports that on a
Model DG–100 sailplane the universal
bearing of the lower rudder mounting
slipped out of the bearing support and
the rudder fell out. Further, the LBA
reports that this kind of failure may
occur on other DG series sailplanes.
What is the potential impact if FAA
took no action? The universal bearing
slipping out could result in the rudder
separating from its support. This failure
could lead to loss of sailplane control
during flight operations.
Has FAA taken any action to this
point? We issued a proposal to amend
part 39 of the Federal Aviation
Regulations (14 CFR part 39) to include
an AD that would apply to all GlaserDirks Flugzeugbau GmbH Models DG–
100 and DG–400 sailplanes and certain
DG Flugzeugbau GmbH Models DG–500
Elan Series and DG–500M sailplanes.
This proposal was published in the
Federal Register as a notice of proposed
rulemaking (NPRM) on October 5, 2005
(70 FR 58110). The NPRM proposed to
require you to modify or replace the
complete rudder mount assembly and
ensure that the securing washer,
castellated nut, and new split pins are
installed.
Discussion
What events have caused this AD?
The Luftfahrt-Bundesamt (LBA), which
is the airworthiness authority for
Germany, recently notified FAA that an
unsafe condition may exist on all
Was the public invited to comment?
We provided the public the opportunity
to participate in developing this AD. We
received no comments on the proposal
or on the determination of the cost to
the public.
Comments
5585
Conclusion
What is FAA’s final determination on
this issue? We have carefully reviewed
the available data and determined that
air safety and the public interest require
adopting the AD as proposed except for
minor editorial corrections. We have
determined that these minor
corrections:
—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.
Changes to 14 CFR Part 39—Effect on
the AD
How does the revision to 14 CFR part
39 affect this AD? On July 10, 2002, the
FAA published a new version of 14 CFR
part 39 (67 FR 47997, July 22, 2002),
which governs the FAA’s AD system.
This regulation now includes material
that relates to altered products, special
flight permits, and alternative methods
of compliance. This material previously
was included in each individual AD.
Since this material is included in 14
CFR part 39, we will not include it in
future AD actions.
Costs of Compliance
How many sailplanes does this AD
impact? We estimate that this AD affects
75 sailplanes in the U.S. registry.
What is the cost impact of this AD on
owners/operators of the affected
sailplanes? We estimate the following
costs to do the replacement of the
complete rudder mount assembly. We
have no way of determining the number
of sailplanes that may need this
replacement:
Labor cost
Parts cost
Total cost

Regulatory Findings
Will this AD impact various entities?
We have 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.
Will this AD involve a significant rule
or regulatory action? For the reasons
discussed above, I certify that 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); and
3. 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.
We prepared a summary of the costs
to comply with this AD (and other
information as included in the
Regulatory Evaluation) and placed it in
the AD Docket. You may get a copy of

SUMMARY: The Commodity Futures
Trading Commission (‘‘Commission’’ or
‘‘CFTC’’) is amending Commission
regulations that impose minimum
financial and related reporting
requirements upon each person
registered as a futures commission
merchant (‘‘FCM’’). The amended
regulations address the capital
computations of FCMs that are
registered with the Securities and
Exchange Commission (‘‘SEC’’) as
securities brokers or dealers (‘‘FCM/
BDs’’), and, who, pursuant to SEC’s
regulations governing consolidated
supervised entities (‘‘CSEs’’), have
received SEC approval to use internal
mathematical models to determine the
deductions from their capital for market
risk and credit risk associated with their
proprietary trading assets. Subject to the
reporting and other requirements
specified in the amended regulations,
these FCM/BDs may elect to compute
their adjusted net capital using their
SEC-approved alternative market risk
and credit risk capital deductions in
lieu of CFTC requirements. The
Commission is also adopting other rule
amendments that address confidential
treatment for the reports and statements
that would be required to be filed under
the amended regulations, and also
address the confidential treatment of
certain other information that all FCMs
must file with both the Commission and
the SEC.
Finally, the Commission is also
adopting amendments that will affect
the minimum financial requirements of
FCMs and introducing brokers (‘‘IBs’’)

by reducing the capital deductions for
their uncovered inventory or forward
contracts in specified foreign currencies.
This reduction is consistent with
guidance currently provided by the
Commission to FCMs and IBs.

SUPPLEMENTARY INFORMATION:
I. Background
On October 11, 2005, the Commission
published a release in the Federal
Register to provide public notice of, and
request comment on, proposed
amendments to its capital rules.1 The
Commission encourages interested
persons to read the detailed analysis of
the proposing amendments in the
October 11 release, and has included
citations to pertinent pages of the
release as part of the discussion in this
final rulemaking release.2 In response to
the proposals issued by the
Commission, four commenters sent
letters that were generally supportive of
the proposed regulations.3 The
commenters included the National
Futures Association (‘‘NFA’’), a
registered futures association; Goldman,
Sachs and Co., an FCM/BD; and two
industry trade groups, the Futures
Industry Association (‘‘FIA’’) and the
Securities Industry Association
(‘‘SIA’’).4 The comments received from
each of these organizations are
addressed elsewhere in this release, in
connection with the specific
Commission regulations discussed in
these letters.
1 The RIN Number for the release published in
the Federal Register on October 11, 2005 was
identified as 3038–AC19. See 70 FR 58985 (October
11, 2005). The correct RIN Number, 3038–AC05,
has been used in this release.
2 The October 11 Release may be accessed
electronically on the Commission’s Web site, at
https://www.cftc.gov/.
3 The original deadline for the receipt for
comments was extended from November 10th to
November 30, 2005. See 70 FR 70749 (November
23, 2005).

II. Amendments Allowing Alternative
Capital Computation for Proprietary
Trading Assets of Qualifying FCM/BDs
That Are Part of CSEs
A. Request to Commission for
Amendment to Rule 1.17
As noted in the October 11 release,
Commission Rule 1.17(a) requires each
FCM to maintain a minimum amount of
‘‘adjusted net capital’’, which is defined
as the FCM’s net capital less the
deductions, or ‘‘haircuts’’, that are
specified in Rule 1.17(c)(5) and (8).5 For
purposes of the required haircuts on the
FCM’s proprietary positions in
securities, Rule 1.17(c)(5) incorporates
by reference percentage deductions that
are set forth in SEC regulations 17 CFR
240.15c3–1(c)(2)(vi) and (vii). Also,
Commission Rule 1.17(c)(2)(ii), in a
manner similar to the SEC’s
requirements for BDs under 17 CFR
240.15c3–1(c)(2)(iv), requires unsecured
receivables arising from an FCM’s
transactions in over-the-counter
(‘‘OTC’’) derivatives to be excluded from
the FCM’s current assets for purposes of
determining the firm’s regulatory
capital. The deductions required for
other proprietary assets of the FCM are
set forth in other parts of Commission
Rule 1.17(c).
The October 11 release also noted that
the Commission and SEC have, to the
extent practical, harmonized their
respective capital rules in order to avoid
creating inconsistent regulatory
obligations for firms that are duallyregistered FCMs and securities brokers
or dealers (‘‘BDs’’). This harmonization
of capital rules extends to the
computation of net capital and adjusted
net capital, and to the qualifications that
subordinated debt must meet in order to
qualify as regulatory capital.
Furthermore, if an FCM is also
registered as a BD, it may file an SEC
Form X–17a–5, ‘‘Financial and
Operational Combined Uniform Single
Report’’ (‘‘FOCUS Report’’) to satisfy its
requirement to file with the Commission
a Form 1–FR–FCM financial report. In
particular, Commission Rule 1.10(h)
treats Part II and Part IIA of the FOCUS
report as acceptable substitutes for the
Form 1–FR–FCM, provided that the
FOCUS report includes all information
required to be furnished on and
submitted with Form 1–FR–FCM. Also,
for those portions of the Form 1–FR–
FCM that the Commission has
designated as either publicly available
or as exempt from mandatory public
5 The rules of the Commission cited in this
release may be found at 17 CFR Ch. I (2005). SEC
rules cited in this release may be found at 17 CFR
Ch. II (2005).

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this AD? The Luftfahrt-Bundesamt (LBA),
which is the airworthiness authority for Germany, recently notified FAA
that an unsafe condition may exist on all Glaser-Dirks Flugzeugbau GmbH
Models DG-100 and DG-400 sailplanes and certain DG Flugzeugbau GmbH
Models DG-500 Elan Series and DG-500M sailplanes. The LBA reports that
on a Model DG-100 sailplane the universal bearing of the lower rudder
mounting slipped out of the bearing support and the rudder fell out.
Further, the LBA reports that this kind of failure may occur on other
DG series sailplanes.
What is the potential impact if FAA took no action? The universal
bearing slipping out could result in the rudder separating from its
support. This failure could lead to loss of sailplane control during
flight operations.
Has FAA taken any action to this point? We issued a proposal to
amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to
include an AD that would apply to all Glaser-Dirks Flugzeugbau GmbH
Models DG-100 and DG-400 sailplanes and certain DG Flugzeugbau GmbH
Models DG-500 Elan Series and DG-500M sailplanes. This proposal was
published in the Federal Register as a notice of proposed rulemaking
(NPRM) on October 5, 2005 (70 FR 58110). The NPRM proposed to require
you to modify or replace the complete rudder mount assembly and ensure
that the securing washer, castellated nut, and new split pins are
installed.
Comments
Was the public invited to comment? We provided the public the
opportunity to participate in developing this AD. We received no
comments on the proposal or on the determination of the cost to the
public.
Conclusion
What is FAA's final determination on this issue? We have carefully
reviewed the available data and determined that air safety and the
public interest require adopting the AD as proposed except for minor
editorial corrections. We have determined that these minor corrections:
--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.
Changes to 14 CFR Part 39--Effect on the AD
How does the revision to 14 CFR part 39 affect this AD? On July 10,
2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997,
July 22, 2002), which governs the FAA's AD system. This regulation now
includes material that relates to altered products, special flight
permits, and alternative methods of compliance. This material
previously was included in each individual AD. Since this material is
included in 14 CFR part 39, we will not include it in future AD
actions.
Costs of Compliance
How many sailplanes does this AD impact? We estimate that this AD
affects 75 sailplanes in the U.S. registry.
What is the cost impact of this AD on owners/operators of the
affected sailplanes? We estimate the following costs to do the
replacement of the complete rudder mount assembly. We have no way of
determining the number of sailplanes that may need this replacement:
------------------------------------------------------------------------
Total cost
Labor cost Parts cost per sailplane
------------------------------------------------------------------------
2 work hours x $65 = $130............... $265 $395
------------------------------------------------------------------------
We estimate the following costs to do the modification of the
complete rudder mount assembly. We have no way of determining the
number of sailplanes that may need this modification:
------------------------------------------------------------------------
Total cost
Labor cost Parts cost per sailplane
------------------------------------------------------------------------
3 work hours x $65 = $195......... Not applicable...... $195
------------------------------------------------------------------------
Authority for This Rulemaking
What authority does FAA have for issuing this rulemaking action?
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
[[Page 5586]]
because it addresses an unsafe condition that is likely to exist or
develop on products identified in this AD.
Regulatory Findings
Will this AD impact various entities? We have 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.
Will this AD involve a significant rule or regulatory action? For
the reasons discussed above, I certify that 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); and
3. 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.
We prepared a summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``Docket
No. FAA-2005-22157; Directorate Identifier 2005-CE-44-AD'' in your
request.
