Model L 23 Super Blanik Gliders Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are superseding an existing airworthiness directive (AD) for the products listed above. 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: SUMMARY: Cracks on the stabilizer elevator inner ´ hinges of seven L 23 SUPERBLANIK sailplanes have been detected during an inspection. This condition, if not corrected, could result in no longer retaining the elevator in place and in jamming of the Pilot’s elevator control system, and subsequent loss of elevator control. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective August 30, 2010. As of April 26, 2010 (75 FR 17295, April 6, 2010), the Director of the Federal Register approved the incorporation by reference of Aircraft Industries, a.s. Mandatory Bulletin MB No.: L23/052a, dated March 2, 2010, listed in this AD. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at the Docket Management Facility, U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC 20590. FOR FURTHER INFORMATION CONTACT: Greg Davison, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, E:\FR\FM\26JYR1.SGM 26JYR1 43396 Federal Register / Vol. 75, No. 142 / Monday, July 26, 2010 / Rules and Regulations Room 301, ACE–112, Kansas City, Missouri 64106; telephone: (816) 329– 4130; fax: (816) 329–4090. 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 April 29, 2010 (75 FR 22543), and proposed to supersede AD 2010–08–01, Amendment 39–16256 (75 FR 17295; April 6, 2010). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states that: Cracks on the stabilizer elevator inner ´ hinges of seven L 23 SUPERBLANIK sailplanes have been detected during an inspection. This condition, if not corrected, could result in no longer retaining the elevator in place and in jamming of the Pilot’s elevator control system, and subsequent loss of elevator control. For the reasons stated above, this Emergency AD requires the inspection of the elevator inner hinges, and the accomplishment of the relevant corrective actions as necessary. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. wwoods2 on DSK1DXX6B1PROD with RULES_PART 1 Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a Note within the AD. Costs of Compliance We estimate that this AD will affect 103 products of U.S. registry. We also estimate that it will take about 2 workhours per product to comply with the VerDate Mar<15>2010 14:07 Jul 23, 2010 Jkt 220001 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 to the U.S. operators to be $17,510 or $170 per product. In addition, we estimate that any necessary follow-on actions would take about 4 work-hours and require parts costing $500, for a cost of $840 per product. 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 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 regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD Docket. Examining the AD Docket You may examine the AD docket on the Internet at https:// www.regulations.gov; or in person at the Docket Management Facility between 9 PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Airworthiness Directives; Aircraft Industries a.s. Model L 23 
Super Blanik Gliders

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for the products listed above. 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:

    Cracks on the stabilizer elevator inner hinges of seven L 23 
SUPERBLAN[Iacute]K sailplanes have been detected during an 
inspection.
    This condition, if not corrected, could result in no longer 
retaining the elevator in place and in jamming of the Pilot's 
elevator control system, and subsequent loss of elevator control.

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective August 30, 2010.
    As of April 26, 2010 (75 FR 17295, April 6, 2010), the Director of 
the Federal Register approved the incorporation by reference of 
Aircraft Industries, a.s. Mandatory Bulletin MB No.: L23/052a, dated 
March 2, 2010, listed in this AD.

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 April 29, 2010 (75 
FR 22543), and proposed to supersede AD 2010-08-01, Amendment 39-16256 
(75 FR 17295; April 6, 2010). That NPRM proposed to correct an unsafe 
condition for the specified products. The MCAI states that:

    Cracks on the stabilizer elevator inner hinges of seven L 23 
SUPERBLAN[Iacute]K sailplanes have been detected during an 
inspection.
    This condition, if not corrected, could result in no longer 
retaining the elevator in place and in jamming of the Pilot's 
elevator control system, and subsequent loss of elevator control.
    For the reasons stated above, this Emergency AD requires the 
inspection of the elevator inner hinges, and the accomplishment of 
the relevant corrective actions as necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the AD.

Costs of Compliance

    We estimate that this AD will affect 103 products of U.S. registry. 
We also estimate that it will take about 2 work-hours 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 to the U.S. 
operators to be $17,510 or $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 4 work-hours and require parts costing $500, for a cost of 
$840 per product. 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 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 regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD Docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at https://www.regulations.gov; 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.

Affected ADs

    (b) This AD supersedes AD 2010-08-01, Amendment 39-16256.

Applicability

    (c) This AD applies to Aircraft Industries a.s. Model L 23 Super 
Blanik Gliders, all serial numbers, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 55: 
Stabilizers.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    Cracks on the stabilizer elevator inner hinges of seven L 23 
SUPERBLAN[Iacute]K sailplanes have been detected during an 
inspection.
    This condition, if not corrected, could result in no longer 
retaining the elevator in place and in jamming of the Pilot's 
elevator control system, and subsequent loss of elevator control.
    For the reasons stated above, this Emergency AD requires the 
inspection of the elevator inner hinges, and the accomplishment of 
the relevant corrective actions as necessary.
