ACTION: Final rule. AGENCY: SUMMARY: The FAA adopts a new airworthiness directive (AD) for certain Mooney Airplane Company, Inc., Models M20M and M20R airplanes. This AD requires you to remove the upper left and upper right engine mount attaching hardware, cut out and remove the upholstery and insulation between the fuselage tubular frame and the firewall, and replace the upper left and upper right engine mount attaching hardware with the new parts kit. This AD results from failure of the engine mount attaching hardware to maintain torque as a result of firewall insulation and upholstery being compressed between the fuselage tubular frame and the firewall at the upper left and upper right engine mount attach points. We are issuing this AD to prevent the upper right and upper left engine mounting hardware from losing torque, which could result in a reduction in engine mount load carrying capability and could lead to engine mount failure. DATES: This AD becomes effective on April 9, 2007. As of April 9, 2007, the Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation.

SUPPLEMENTARY INFORMATION: Discussion On November 7, 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 certain Mooney Airplane Company, Inc. Models M20M and M20R airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on November 7, 2006 (71 FR 65062). The NPRM proposed to retorque the upper left and upper right engine mounting hardware as an interim action. The NPRM also proposed to remove the upper left and upper right engine mount attaching hardware, cut out and remove the upholstery and insulation between the fuselage tubular frame and the firewall, and replace the upper left and upper right engine mount attaching hardware with the new parts kit. 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: Jack Buster of the Modification and Replacement Parts Association (MARPA) suggests that paragraph (g) of the proposed action be amended to include the Internet Uniform Resource Locator (URL) address for the relevant service information. We agree with the commenter’s (Jack Buster, MARPA) recommendation. We added the manufacturer’s Internet URL address in the information on how to obtain the relevant service information. Conclusion Since the NPRM was published, the manufacturer has revised the applicable service bulletin to clarify the fastener torque requirement. The change does not change the intent of the required action and does not create any additional burden on the owners/ operators. The AD will reference the appropriate service information: Mooney Airplane Company, Inc. Service E:\FR\FM\05MRR1.SGM 05MRR1 Federal Register / Vol. 72, No. 42 / Monday, March 5, 2007 / Rules and Regulations Bulletin M20–292A, dated December 22, 2006, but will give credit to anyone who has already done the action per the original service bulletin. 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 198 airplanes in the U.S. registry. We estimate the following costs to accomplish the required modifications: Total cost per airplane Total cost on U.S. operators Not Applicable ................................. $40 $7,920 $20 ................................................... 180 35,640 Labor cost Parts cost Retorquing of the upper left and upper right engine mounting hardware: .5 work-hours × $80 per hour = $40. Removing insulation and upholstery material at the engine mount upper right and upper left attaching points, and installing engine mount attaching hardware with the new parts kit: 2 work-hours X $80 per hour = $160. 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 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–2006–26071; Directorate Identifier 2006–CE–51–AD’’ in your request. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment 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.

SUPPLEMENTARY INFORMATION:

Discussion

    On November 7, 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 certain Mooney Airplane Company, Inc. Models M20M and 
M20R airplanes. This proposal was published in the Federal Register as 
a notice of proposed rulemaking (NPRM) on November 7, 2006 (71 FR 
65062). The NPRM proposed to retorque the upper left and upper right 
engine mounting hardware as an interim action. The NPRM also proposed 
to remove the upper left and upper right engine mount attaching 
hardware, cut out and remove the upholstery and insulation between the 
fuselage tubular frame and the firewall, and replace the upper left and 
upper right engine mount attaching hardware with the new parts kit.

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: Jack Buster of the Modification and Replacement 
Parts Association (MARPA) suggests that paragraph (g) of the proposed 
action be amended to include the Internet Uniform Resource Locator 
(URL) address for the relevant service information.
    We agree with the commenter's (Jack Buster, MARPA) recommendation. 
We added the manufacturer's Internet URL address in the information on 
how to obtain the relevant service information.

Conclusion

    Since the NPRM was published, the manufacturer has revised the 
applicable service bulletin to clarify the fastener torque requirement. 
The change does not change the intent of the required action and does 
not create any additional burden on the owners/operators. The AD will 
reference the appropriate service information: Mooney Airplane Company, 
Inc. Service

Bulletin M20-292A, dated December 22, 2006, but will give credit to 
anyone who has already done the action per the original service 
bulletin.
    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 198 airplanes in the U.S. 
registry.
    We estimate the following costs to accomplish the required 
modifications:

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-2006-26071; Directorate Identifier 2006-CE-51-AD'' in your 
request.
