ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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: mstockstill on DSK4VPTVN1PROD with RULES SUMMARY: A report has been received of an incident where one of the two bolts attaching the actuator mounting bracket to the MLG [main landing gear] Shock Strut was found loose, leading to failure of the other attachment bolt, subsequently resulting in failure of the bracket. VerDate Mar<15>2010 15:47 Jul 14, 2011 Jkt 223001 This condition, if not detected and corrected, could prevent the MLG to extend to the full down-and-locked position, possibly resulting in MLG collapse upon landing or during roll-out, with consequent damage to the aeroplane and injury to the occupants. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective August 19, 2011. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of August 1, 2011. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC.

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 8, 2011 (76 FR 19719). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: A report has been received of an incident where one of the two bolts attaching the actuator mounting bracket to the MLG Shock Strut was found loose, leading to failure of the other attachment bolt, subsequently resulting in failure of the bracket. This condition, if not detected and corrected, could prevent the MLG to extend to the full down-and-locked position, possibly resulting in MLG collapse upon landing or during roll-out, with consequent damage to the aeroplane and injury to the occupants. To correct this potentially unsafe condition, SAAB has published Service Bulletin (SB) 2000–32–073, describing a [detailed] inspection of the attachment bolts [and nuts] to detect any loose bolts [and nuts], follow-up corrective action(s), depending on findings, and the installation of the correct number of washers. For the reasons described above, this EASA AD requires the accomplishment of the actions described in SAAB SB 2000–32–073. Required actions, if any loose parts are found, include replacing the bolt with a PO 00000 Frm 00077 Fmt 4700 Sfmt 4700 41665 new bolt, and then doing a detailed inspection of the bolts for uniform or fretting corrosion; a detailed inspection of the actuator mounting bracket and shock struts for damage, cracks, and signs of corrosion; and doing corrective actions if necessary. Corrective actions include removing corrosion, replacing affected bolts with new bolts, tightening loose nuts, repairing, and installing the correct number of washers. You may obtain further information by examining the MCAI in the AD docket. 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 our FAA policies. Any such differences are highlighted in a NOTE within the AD. Costs of Compliance We estimate that this AD will affect about 8 products of U.S. registry. We also estimate that it will take about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $1,039 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $8,992, or $1,124 per product. In addition, we estimate that any necessary follow-on actions would take about 10 work-hours and require parts costing $1,039, for a cost of $1,889 per E:\FR\FM\15JYR1.SGM 15JYR1 41666 Federal Register / Vol. 76, No. 136 / Friday, July 15, 2011 / Rules and Regulations List of Subjects in 14 CFR Part 39 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. mstockstill on DSK4VPTVN1PROD with RULES 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 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 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 Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Models B300 and B300C (C–12W) airplanes. This AD was prompted by an error found in the take-off speeds and field lengths published in the FAA-approved airplane flight manual. This AD requires a correction to the published data in the airplane flight manual and the pilot’s operating handbook to ensure it corresponds with the published data in the pilot’s checklist. This condition, if not corrected, could result in a pilot taking off from shorter runways than required by the airplane if the airplane loses an engine after takeoff decision speed (V1).

That NPRM proposed to require inserting an update to the performance charts in the FAA-approved Airplane Flight Manual and the Pilot’s Operating Handbook, part number (P/N) 130– 590031–245. The required runway distances published in the current manual could be up to 320 feet shorter than what is necessary. Hawker Beechcraft Corporation determined data in the pilot’s checklist (P/N 130– 590031–273) was correct. This condition, if not corrected, could result in taking off from shorter runways than required by the airplane if the airplane loses an engine after takeoff decision speed (V1). This could result in the airplane running out of runway before take-off can be accomplished. 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 relevant data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes: • 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 proposed AD affects 46 airplanes of U.S. registry. E:\FR\FM\15JYR1.SGM 15JYR1

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) originated 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:

    A report has been received of an incident where one of the two 
bolts attaching the actuator mounting bracket to the MLG [main 
landing gear] Shock Strut was found loose, leading to failure of the 
other attachment bolt, subsequently resulting in failure of the 
bracket.
    This condition, if not detected and corrected, could prevent the 
MLG to extend to the full down-and-locked position, possibly 
resulting in MLG collapse upon landing or during roll-out, with 
consequent damage to the aeroplane and injury to the occupants.
* * * * *
We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective August 19, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 1, 
2011.

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 8, 2011 (76 FR 
19719). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    A report has been received of an incident where one of the two 
bolts attaching the actuator mounting bracket to the MLG Shock Strut 
was found loose, leading to failure of the other attachment bolt, 
subsequently resulting in failure of the bracket.
    This condition, if not detected and corrected, could prevent the 
MLG to extend to the full down-and-locked position, possibly 
resulting in MLG collapse upon landing or during roll-out, with 
consequent damage to the aeroplane and injury to the occupants.
    To correct this potentially unsafe condition, SAAB has published 
Service Bulletin (SB) 2000-32-073, describing a [detailed] 
inspection of the attachment bolts [and nuts] to detect any loose 
bolts [and nuts], follow-up corrective action(s), depending on 
findings, and the installation of the correct number of washers.
    For the reasons described above, this EASA AD requires the 
accomplishment of the actions described in SAAB SB 2000-32-073.

Required actions, if any loose parts are found, include replacing the 
bolt with a new bolt, and then doing a detailed inspection of the bolts 
for uniform or fretting corrosion; a detailed inspection of the 
actuator mounting bracket and shock struts for damage, cracks, and 
signs of corrosion; and doing corrective actions if necessary. 
Corrective actions include removing corrosion, replacing affected bolts 
with new bolts, tightening loose nuts, repairing, and installing the 
correct number of washers. You may obtain further information by 
examining the MCAI in the AD docket.

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 our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect about 8 products of U.S. 
registry. We also estimate that it will take about 1 work-hour per 
product to comply with the basic requirements of this AD. The average 
labor rate is $85 per work-hour. Required parts will cost about $1,039 
per product. Where the service information lists required parts costs 
that are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of this AD to the 
U.S. operators to be $8,992, or $1,124 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 10 work-hours and require parts costing $1,039, for a cost 
of $1,889 per

[[Page 41666]]

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 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 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 Operations office 
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 Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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 AD:

2011-14-12 Saab AB, Saab Aerosystems: Amendment 39-16747. Docket No. 
FAA-2011-0307; Directorate Identifier 2010-NM-111-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective August 
19, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to all Saab AB, Saab Aerosystems Model SAAB 
2000 airplanes, certificated in any category.

Subject

    (d) Air Transport Association (ATA) of America Code 32: Landing 
gear.

Reason

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

    A report has been received of an incident where one of the two 
bolts attaching the actuator mounting bracket to the MLG [main 
landing gear] Shock Strut was found loose, leading to failure of the 
other attachment bolt, subsequently resulting in failure of the 
bracket.
    This condition, if not detected and corrected, could prevent the 
MLG to extend to the full down-and-locked position, possibly 
resulting in MLG collapse upon landing or during roll-out, with 
consequent damage to the aeroplane and injury to the occupants.
* * * * *

    (f) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Inspection
