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 per sailplane 2 work hours × $65 = $130 ......................................................................................................................................... $265 $395 We estimate the following costs to do the modification of the complete rudder mount assembly.

ACTION: Final rule. wwhite on PROD1PC61 with RULES AGENCY: 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’’) VerDate Aug 31 2005 12:15 Feb 08, 2006 Jkt 208001 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. DATES: Effective February 2, 2006. FOR FURTHER INFORMATION CONTACT: Thomas J.

Electronic mail: (tsmith@cftc.gov) or (tdiaz@cftc.gov). 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). 4 The comment letters are available for inspection and copying at the Commission’s Washington office in its public reading room, Room 4072, Three Lafayette Centre, 1155 21st Street, NW., Washington, DC 20581. The telephone number for the public reading room is (202) 418–5025.

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). E:\FR\FM\02FER1.LOC 02FER1

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.

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.

What Is the Unsafe Condition Presented in This AD?

    (d) This AD is the result of mandatory continuing airworthiness 
information (MCAI) issued by the airworthiness authority for 
Germany. The actions specified in this AD are intended 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.
    (e) To address this problem, you must do the following:
