ACTION: Final rule. AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for all Mitsubishi Heavy Industries MU–2B series airplanes. This AD requires you to do the following: Remove and visually inspect the wing attach barrel nuts, bolts, and retainers for cracks, corrosion, and fractures; replace any cracked, corroded, or fractured parts; inspect reusable wing attach barrel nuts and bolts for deformation and irregularities in the threads; check the minimum breakaway torque of reused wing attach barrel nuts; replace any deformed or irregular parts; and install new or reusable parts and torque to the correct value. This AD results from a recent safety evaluation that used a data-driven approach to evaluate the design, operation, and maintenance of the MU– 2B series airplanes in order to determine their safety and define what steps, if any, are necessary for their safe operation. Part of that evaluation was the identification of unsafe conditions that exist or could develop on the affected type design airplanes. We are issuing this AD to detect and correct cracks, corrosion, fractures, and incorrect torque values in the wing attach barrel nuts, which could result in failure of the wing barrel nuts and/or associated wing attachment hardware. This failure could lead to in-flight separation of the outer wing from the center wing section and result in loss of controlled flight. DATES: This AD becomes effective on August 11, 2006. As of August 11, 2006, the Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation. ADDRESSES: For service information identified in this AD, contact Mitsubishi Heavy Industries America, Inc., 4951 Airport Parkway, Suite 800, Addison, Texas 95001; telephone: (972) 934– 5480; fax: (972) 934–5488, or Turbine Aircraft Services, Inc., 4550 Jimmy Doolittle Drive, Addison, Texas 75001; telephone: (972) 248–3108; facsimile: (972) 248–3321.

SUPPLEMENTARY INFORMATION: Discussion On April 18, 2006, 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 Mitsubishi Heavy Industries MU–2B series airplanes. This proposal was published in the Federal Register as a supplemental notice of proposed rulemaking (NPRM) on April 24, 2006 (71 FR 20915). We issued the supplemental NPRM to incorporate revised manufacturer service information that adds airplanes to the applicability, revises the serial numbers of the affected airplanes, and updates the manufacturer’s contact information. The supplemental NPRM proposed to require you to do the following: • Remove and visually inspect the wing attach barrel nuts, bolts, and retainers for cracks, corrosion, and fractures; • Replace any cracked, corroded, or fractured wing attach barrel nuts, bolts, and retainers with new parts; • Inspect reusable wing attach barrel nuts and bolts for deformation and irregularities in the threads; • Check the minimum breakaway torque of reused wing attach barrel nuts; • Replace any deformed or irregular wing attach barrel nuts or bolts with new parts; and • Install new or reusable parts and torque to the correct value. 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 399 airplanes in the U.S. registry. We estimate the following costs to do the inspection: Parts cost Total cost for each airplane 12 work-hours × $80 an hour = $960 .................................................................. cprice-sewell on PROD1PC66 with RULES Labor cost Not applicable .... $960 We estimate the following costs to do any necessary replacements that will be VerDate Aug<31>2005 14:28 Jun 28, 2006 Jkt 208001 required based on the results of the inspection.

Any necessary replacements will be done at the time of inspection. $60 for each barrel nut. There are 8 barrel nuts on each airplane. Possible total cost of: $60 × 8 = $480. The FAA is committed to updating the aviation community of expected costs associated with the MU–2B series airplane safety evaluation conducted in 2005. As a result of that commitment, the accumulating expected costs of all ADs related to the MU–2B series airplane safety evaluation may be found in the Final Report section at the following Web site: http://www.faa.gov/ aircraft/air_cert/design_approvals/ small_airplanes/cos/ mu2_foia_reading_library/. 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.

Airworthiness Directives; Mitsubishi Heavy Industries MU-2B 
Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Mitsubishi Heavy Industries MU-2B series airplanes. This AD requires 
you to do the following: Remove and visually inspect the wing attach 
barrel nuts, bolts, and retainers for cracks, corrosion, and fractures; 
replace any cracked, corroded, or fractured parts; inspect reusable 
wing attach barrel nuts and bolts for deformation and irregularities in 
the threads; check the minimum breakaway torque of reused wing attach 
barrel nuts; replace any deformed or irregular parts; and install new 
or reusable parts and torque to the correct value. This AD results from 
a recent safety evaluation that used a data-driven approach to evaluate 
the design, operation, and maintenance of the MU-2B series airplanes in 
order to determine their safety and define what steps, if any, are 
necessary for their safe operation. Part of that evaluation was the 
identification of unsafe conditions that exist or could develop on the 
affected type design airplanes. We are issuing this AD to detect and 
correct cracks, corrosion, fractures, and incorrect torque values in 
the wing attach barrel nuts, which could result in failure of the wing 
barrel nuts and/or associated wing attachment hardware. This failure 
could lead to in-flight separation of the outer wing from the center 
wing section and result in loss of controlled flight.

DATES: This AD becomes effective on August 11, 2006.
    As of August 11, 2006, the Director of the Federal Register 
approved the incorporation by reference of certain publications listed 
in the regulation.

SUPPLEMENTARY INFORMATION:

Discussion

    On April 18, 2006, 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 Mitsubishi Heavy Industries MU-2B series airplanes. 
This proposal was published in the Federal Register as a supplemental 
notice of proposed rulemaking (NPRM) on April 24, 2006 (71 FR 20915). 
We issued the supplemental NPRM to incorporate revised manufacturer 
service information that adds airplanes to the applicability, revises 
the serial numbers of the affected airplanes, and updates the 
manufacturer's contact information. The supplemental NPRM proposed to 
require you to do the following:
     Remove and visually inspect the wing attach barrel nuts, 
bolts, and retainers for cracks, corrosion, and fractures;
     Replace any cracked, corroded, or fractured wing attach 
barrel nuts, bolts, and retainers with new parts;
     Inspect reusable wing attach barrel nuts and bolts for 
deformation and irregularities in the threads;
     Check the minimum breakaway torque of reused wing attach 
barrel nuts;
     Replace any deformed or irregular wing attach barrel nuts 
or bolts with new parts; and
     Install new or reusable parts and torque to the correct 
value.

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 399 airplanes in the U.S. 
registry.
    We estimate the following costs to do the inspection:

----------------------------------------------------------------------------------------------------------------
                                                             Total cost for
           Labor cost                    Parts cost          each airplane       Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
12 work-hours x $80 an hour =     Not applicable..........            $960   $960 x 399 = $383,040
 $960.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that will be required based on the results of the inspection. We have 
no way of determining the number of airplanes that may need this 
replacement:

 inspection.                    airplane. Possible
                                total cost of: $60 x
                                8 = $480.
------------------------------------------------------------------------

    The FAA is committed to updating the aviation community of expected 
costs associated with the MU-2B series airplane safety evaluation 
conducted in 2005. As a result of that commitment, the accumulating 
expected costs of all ADs related to the MU-2B series airplane safety 
evaluation may be found in the Final Report section at the following 
Web site: http://www.faa.gov/aircraft/air_cert/design_approvals/
small_airplanes/cos/mu2_foia_reading_library/.

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-2006-23578; Directorate Identifier 2006-CE-01-AD'' in your

Docket No. FAA-2006-23578; Directorate Identifier 2006-CE-01-AD.

Effective Date

    (a) This AD becomes effective on August 11, 2006.

Affected ADs

    (b) None.

Applicability

    (c) This AD affects the following airplane models and serial 
numbers that are certificated in any category:

----------------------------------------------------------------------------------------------------------------
              Model                                                 Serial Nos.
----------------------------------------------------------------------------------------------------------------
MU-2B-10.........................  101 through 120 (Except 102, 114, 115, and 118).
MU-2B-15.........................  114, 115, and 118.
MU-2B-20.........................  102, and 121 through 238.
MU-2B-25.........................  239 through 318 (Except 313), and 313SA.
MU-2B-26.........................  319 through 347 (Except 321), and 349SA.

MU-2B-36.........................  501, and 655 through 696 (Except 661).
MU-2B-36A........................  661SA, and 697SA through 730SA (Except 700SA).
MU-2B-40.........................  365SA.
MU-2B-60.........................  700SA.
----------------------------------------------------------------------------------------------------------------

Unsafe Condition

    (d) This AD results from a recent safety evaluation that used a 
data-driven approach to evaluate the design, operation, and 
maintenance of the MU-2B series airplanes in order to determine 
their safety and define what steps, if any, are necessary for their 
safe operation. Part of that evaluation was to identify unsafe 
conditions that exist or could develop on the affected type design 
airplanes. The actions specified in this AD are intended to detect 
and correct cracks, corrosion, fractures, and incorrect torque 
values in the wing attach barrel nuts, which could result in failure 
of the wing attach barrel nuts and/or associated wing attachment 
hardware. This failure could lead to in-flight separation of the 
outer wing from the center wing section and result in loss of 
controlled flight.

Compliance

    (e) To address this problem, you must do the following, unless 
already done:
