SUPPLEMENTARY INFORMATION: Discussion On January 30, 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 the GMD actuator nut assembly, P/N GMD115–810029–17 or P/N GMD115– 810029–23, that is installed on certain airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on February 3, 2006 (71 FR 5796). The NPRM proposed to require you to determine by maintenance records check and/or inspection whether any actuator nut assembly, P/N GMD115– 810029–17 or P/N GMD115–810029–23, is installed on the right MLG actuator, PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 and, if installed, would require you to replace it with a new actuator nut assembly, P/N GMD115–810029–23B or FAA-approved equivalent P/N. Comments We provided the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal and FAA’s response to each comment: Comment Issue No. 1: Include the Raytheon (Military) Models A200 (C– 12A) and A200 (C–12C) Airplanes in the List of ‘‘Airplanes Affected’’ One commenter writes that the applicability of the proposed AD needs to be expanded. The commenter explains that the Raytheon military Models A200 (C–12A) and A200 (C– 12C) airplanes with standard landing gear have the same actuator assemblies as the airplanes listed in the NPRM, and could have the affected P/N nut installed. We disagree with the commenter that the applicability of the proposed AD needs to be expanded. Although a limited number of the affected actuator assemblies were installed on Models A200 (C–12A) and A200 (C–12C) airplanes, the military operates these airplanes and removed the affected parts from service before the issuance of the NPRM. Paragraph (e)(4) of this AD prohibits the subject actuator nut assembly from being installed on these airplanes in the future. The AD specifies that it applies to the subject actuator nut assembly ‘‘installed on, but not limited to’’ specific models listed. We are not changing the final rule AD based on this comment. Comment Issue No. 2: Clarify Applicability of AD by Identifying Raytheon as the Manufacturer of the Affected Airplane Models Two commenters recommend that it should be stated at the beginning of the document that these defective parts are installed on Raytheon airplanes. The commenter explains that stating this early in the AD action would be better form and result in a more easily comprehended document. The FAA agrees with the commenters. We will change the final rule to clearly identify that the affected actuator E:\FR\FM\16JNR1.SGM 16JNR1 34805 Federal Register / Vol. 71, No. 116 / Friday, June 16, 2006 / Rules and Regulations assemblies are installed on certain Raytheon airplane models. 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 1,629 airplanes in the U.S. registry. We estimate the following costs to do the maintenance records check and/or inspection: Labor cost Parts cost Total cost per airplane 1 work-hour × $80 = $80 .......................................... Not Applicable .............................. $80 We estimate the following costs to do any necessary replacements of the actuator nut assembly that would be required based on the results of this inspection. We have no way of Total cost on U.S. operators 1,629 × $80 = $130,320. determining the number of airplanes that may need this replacement: Labor cost Parts cost Total cost per airplane 4 work-hours × $80 = $320 ..................................................................................................................................... $1,700 $2,020 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.

Airworthiness Directives; General Machine--Diecron, Inc. Actuator 
Nut Assembly for the Right Main Landing Gear Installed on Certain 
Raytheon Aircraft Company (Formerly Beech) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA adopts a new airworthiness directive (AD) for General 
Machine--Diecron, Inc. (GMD) actuator nut assembly, part number (P/N) 
GMD115-810029-17 and P/N GMD115-810029-23, that are installed on 
certain Raytheon Aircraft Company (Raytheon) (formerly Beech) airplanes 
that are not equipped with a hydraulic main landing gear (MLG) or 
modified to a hydraulic MLG. This AD requires you to determine by 
maintenance records check and/or inspection whether any actuator nut 
assembly, P/N GMD115-810029-17 or P/N GMD115-810029-23, is installed on 
the right main MLG actuator, and, if installed, requires you to replace 
it with a new actuator nut assembly, P/N GMD115-810029-23B or FAA-
approved equivalent P/N. This AD results from several reports of 
failures of the actuator nut assembly, P/N GMD115-810029-17 and P/N 
GMD115-810029-23. We are issuing this AD to prevent failure of the 
actuator nut assembly for the right MLG actuator, which could result in 
failure of the MLG. This failure could prevent the extension or 
retraction of the MLG.

DATES: This AD becomes effective on July 28, 2006.
    As of July 28, 2006, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in the 
regulation.

SUPPLEMENTARY INFORMATION: 

Discussion

    On January 30, 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 the GMD actuator nut assembly, P/N GMD115-810029-17 or 
P/N GMD115-810029-23, that is installed on certain airplanes. This 
proposal was published in the Federal Register as a notice of proposed 
rulemaking (NPRM) on February 3, 2006 (71 FR 5796). The NPRM proposed 
to require you to determine by maintenance records check and/or 
inspection whether any actuator nut assembly, P/N GMD115-810029-17 or 
P/N GMD115-810029-23, is installed on the right MLG actuator, and, if 
installed, would require you to replace it with a new actuator nut 
assembly, P/N GMD115-810029-23B or FAA-approved equivalent P/N.

Comments

    We provided the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
and FAA's response to each comment:

Comment Issue No. 1: Include the Raytheon (Military) Models A200 (C-
12A) and A200 (C-12C) Airplanes in the List of ``Airplanes Affected''

    One commenter writes that the applicability of the proposed AD 
needs to be expanded. The commenter explains that the Raytheon military 
Models A200 (C-12A) and A200 (C-12C) airplanes with standard landing 
gear have the same actuator assemblies as the airplanes listed in the 
NPRM, and could have the affected P/N nut installed.
    We disagree with the commenter that the applicability of the 
proposed AD needs to be expanded. Although a limited number of the 
affected actuator assemblies were installed on Models A200 (C-12A) and 
A200 (C-12C) airplanes, the military operates these airplanes and 
removed the affected parts from service before the issuance of the 
NPRM. Paragraph (e)(4) of this AD prohibits the subject actuator nut 
assembly from being installed on these airplanes in the future. The AD 
specifies that it applies to the subject actuator nut assembly 
``installed on, but not limited to'' specific models listed.
    We are not changing the final rule AD based on this comment.

Comment Issue No. 2: Clarify Applicability of AD by Identifying 
Raytheon as the Manufacturer of the Affected Airplane Models

    Two commenters recommend that it should be stated at the beginning 
of the document that these defective parts are installed on Raytheon 
airplanes. The commenter explains that stating this early in the AD 
action would be better form and result in a more easily comprehended 
document.
    The FAA agrees with the commenters. We will change the final rule 
to clearly identify that the affected actuator

[[Page 34805]]

assemblies are installed on certain Raytheon airplane models.

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 1,629 airplanes in the U.S. 
registry.
    We estimate the following costs to do the maintenance records check 
and/or inspection:

----------------------------------------------------------------------------------------------------------------
                                                   Total cost per
          Labor cost               Parts cost         airplane              Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $80 = $80.......  Not Applicable..             $80   1,629 x $80 = $130,320.
----------------------------------------------------------------------------------------------------------------

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

------------------------------------------------------------------------
                                                          Total cost per
              Labor cost                   Parts cost        airplane
------------------------------------------------------------------------
4 work-hours x $80 = $320.............          $1,700           $2,020
------------------------------------------------------------------------

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

    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-2005-23334; Directorate Identifier 2005-CE-53-AD'' in your
