KG, Model G 103 C Twin III SL Sailplanes Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: SUMMARY: The FAA adopts a new airworthiness directive (AD) that supersedes AD 97–24–09, which applies to certain BURKHART GROB LUFTUND-RAUMFAHRT GmbH & Co. KG (Grob) Model G 103 C Twin III SL sailplanes. AD 97–24–09 currently requires repetitively inspecting the propeller bearing and upper pulley wheel for increased play and, if increased play is found, modifying the propeller bearing and pulley wheel. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. Consequently, this AD requires you to modify the propeller bearing and upper pulley wheel by installing a new securing plate and tightening the grooved nut to the new torque values. We are issuing this AD to prevent loss of the sailplane propeller caused by increased play in the current design propeller bearing and upper pulley wheel. This could result in loss of control of the sailplane. DATES: This AD becomes effective on May 9, 2006. On January 5, 1998 (62 FR 62945, November 26, 1997), the Director of the Federal Register previously approved the incorporation by reference of GROB Luft-und Raumfahrt Service Bulletin No. 869–18, dated March 7, 1996, and GROB Luft-und Raumfahrt Service Bulletin No. 869–18/2, dated July 8, 1996. As of May 9, 2006, the Director of the Federal Register approved the incorporation by reference of GROB Luft-und Raumfahrt Service Bulletin MSB869–18/3, dated May 24, 2002, in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.

SUPPLEMENTARY INFORMATION: Discussion On June 15, 2005, 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 Grob Model G 103 C Twin III SL sailplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on June 21, 2005 (70 FR 35568).

Conclusion 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. Comments Costs of Compliance We provided the public the opportunity to participate in developing this AD. We received no comments on We estimate that this AD affects 8 sailplanes in the U.S. registry. We estimate the following costs to do the modification: Labor cost Parts cost 6 workhours × $65 per hour = $390 ............................................................................................ 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 AD. rwilkins on PROD1PC63 with RULES Regulatory Findings 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. For the reasons discussed above, I certify that this AD: VerDate Aug<31>2005 16:33 Apr 07, 2006 Jkt 208001 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.

SUPPLEMENTARY INFORMATION: Electronic Access This Federal Register document is accessible via the Internet at https:// www.archives.gov/federal-register/ publications. Background In 1996, NMFS published a final rule (61 FR 34570, July 2, 1996) that consolidated six parts of the Code of Federal Regulations (CFR) into one new CFR part (50 CFR part 660). Among the actions in that rule was consolidation of regulations that implemented fishery conservation and management measures for fisheries operating in the exclusive economic zone (EEZ) off the west coast and in the western Pacific. The 1996 action reorganized the rules into a more logical and cohesive order, removed duplicative and outdated provisions, and made editorial changes for readability, clarity and uniformity in the regulatory language. The current action makes the regulations even better organized, and easier for the public to use. Since the 1996 reorganization, there have been significant changes in the fisheries managed under 50 CFR part 660 and in the associated fishery regulations. New subparts have been added that cover west coast highly migratory species fisheries and western Pacific coral reef fisheries. Subparts that apply specifically to fisheries in the western Pacific are currently intermingled with subparts that apply to fisheries off the west coast, and several subparts have been changed substantially. In 2004, NMFS established a new Pacific Islands Region and Pacific E:\FR\FM\10APR1.SGM 10APR1

SUMMARY: The FAA adopts a new airworthiness directive (AD) that 
supersedes AD 97-24-09, which applies to certain BURKHART GROB LUFT-
UND-RAUMFAHRT GmbH & Co. KG (Grob) Model G 103 C Twin III SL 
sailplanes. AD 97-24-09 currently requires repetitively inspecting the 
propeller bearing and upper pulley wheel for increased play and, if 
increased play is found, modifying the propeller bearing and pulley 
wheel. This AD results from mandatory continuing airworthiness 
information (MCAI) issued by the airworthiness authority for Germany. 
Consequently, this AD requires you to modify the propeller bearing and 
upper pulley wheel by installing a new securing plate and tightening 
the grooved nut to the new torque values. We are issuing this AD to 
prevent loss of the sailplane propeller caused by increased play in the 
current design propeller bearing and upper pulley wheel. This could 
result in loss of control of the sailplane.

SUPPLEMENTARY INFORMATION:

Discussion

    On June 15, 2005, 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 Grob Model G 103 C Twin III SL sailplanes. This proposal 
was published in the Federal Register as a notice of proposed 
rulemaking (NPRM) on June 21, 2005 (70 FR 35568). The NPRM proposed to 
supersede AD 97-24-09 with a new AD that would require you to modify 
the propeller bearing and upper pulley wheel by installing a new 
securing plate and tightening the grooved nut to the new torque values.

Comments

    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

    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.

Costs of Compliance

    We estimate that this AD affects 8 sailplanes in the U.S. registry.
    We estimate the following costs to do the modification:

                                                                                  Total cost per   Total cost on

----------------------------------------------------------------------------------------------------------------

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 AD.

Regulatory Findings

    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.
    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-2005-20768; Directorate Identifier 2005-CE-16-AD'' in your 
request.
