Airworthiness Directives; Cessna Aircraft Company, Models 172, 182, and 206 Series Airplanes, 39584-39586 [E7-13984]

Download as PDF 39584 Federal Register / Vol. 72, No. 138 / Thursday, July 19, 2007 / Proposed Rules resulted from amendments to the Act by the Bipartisan Campaign Reform Act of 2002 (‘‘BCRA’’) 1 and the Consolidated Appropriations Act of 2005.2 Prior to the passage of BCRA, the Act and Commission regulations permitted the use of campaign funds for ‘‘any other lawful purpose’’ other than personal use. In BCRA, Congress deleted ‘‘any other lawful purpose’’ from section 439a and retained only four permissible uses of campaign funds. The Commission amended its regulation accordingly.3 Congress later amended section 439a again, in the Consolidated Appropriations Act of 2005, by reinstating ‘‘any other lawful purpose’’ and adding donations to State and local candidates as permissible uses of campaign funds. These changes to the Act have prompted this rulemaking. I. Donations to State and Local Candidates Section 439a(a)(5) of the Act expressly permits Federal candidates and officeholders to donate contributions accepted and other monies received to State and local candidates. The Commission proposes to amend 11 CFR 113.2 accordingly, by adding a new paragraph (d), which would permit Federal candidates and officeholders to donate campaign funds from their authorized committees to ‘‘State and local candidates subject to the provisions of State law.’’ The Commission seeks comment on this proposed revision. II. Any Other Lawful Purpose The Commission also proposes to amend 11 CFR 113.2 by inserting a new paragraph (e), which would state that campaign funds ‘‘may be used for any other lawful purpose, unless such use is personal use under 11 CFR 113.1(g).’’ New paragraph (e) would follow current section 439a(a)(6) of the Act, which permits the use of campaign funds ‘‘for any other lawful purpose,’’ unless the funds are converted by any person to personal use. The Commission seeks comment on this proposed revision to the regulation. The Commission notes that this change to the statute has the effect of superseding the analysis in Advisory Opinions 2003–26 (Voinovich) and 2004–03 (Dooley). cprice-sewell on PROD1PC66 with PROPOSALS 1 Pub.

The Consolidated Appropriations Act of 2005 directed that section 312a(a) of the Act be amended, but was executed by amending section 313(a) of the Act ‘‘as the probable intent of Congress.’’ 2 U.S.C.A. 439a (West 2004). 3 Disclaimers, Fraudulent Solicitation, Civil Penalties, and Personal Use of Campaign Funds; Final Rule, 67 FR 76962, 76970–75 and 76978–79 (Dec. 13, 2002). 2 Pub. VerDate Aug<31>2005 13:52 Jul 18, 2007 Jkt 211001 Certification of No Effect Pursuant to 5 U.S.C. 605(b) (Regulatory Flexibility Act) The Commission certifies that the attached proposed rule would not, if promulgated, have a significant economic impact on a substantial number of small entities. The basis for this certification is that any individuals and not-for-profit entities that would be affected by this proposed rule are not ‘‘small entities’’ under 5 U.S.C. 601. The definition of ‘‘small entity’’ does not include individuals, but classifies a notfor-profit enterprise as a ‘‘small organization’’ if it is independently owned and operated and not dominant in its field. 5 U.S.C. 601(4). The proposed rule would affect authorized committees, which are not independently owned and operated because they are not financed and controlled by a small identifiable group of individuals. Authorized committees are financed by contributions from a large number of persons and controlled by the candidate and the candidate’s campaign employees and volunteers. To the extent that any authorized committees might be considered ‘‘small organizations,’’ the number that would be affected by this proposed rule is not substantial. The proposed rule also would not impose any additional restrictions or increase the costs of compliance for authorized committees. Instead, the proposed rule would provide authorized committees with additional options for using campaign funds. The proposed rule would not impose an undue burden upon authorized committees because they are already required to report the use of campaign funds to the Commission. Therefore, the attached proposed rule, if promulgated, would not have a significant economic impact on a substantial number of small entities. List of Subjects in 11 CFR Part 113 Campaign funds.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna), Models 172, 182, and 206 series airplanes. This proposed AD would require you to remove the seats, modify the seat base/back attach brackets, and reinstall the seats of all the crew seats of the affected airplanes and seats 3 and 4 on Model 206 series airplanes. This proposed AD results from reports of the seat base/back attach bracket failing where it is welded to the seat base. We are proposing this AD to prevent failure of the seat base/back attach brackets, which could result in the seats collapsing backwards during flight with consequent loss of control. DATES: We must receive comments on this proposed AD by September 17, 2007.

We will consider all comments received by the closing date and may amend the proposed AD in light of those comments. We will post all comments we receive, without change, to http:// dms.dot.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive concerning this proposed AD. Discussion We have received three reports of the seat base/back bracket failing on Cessna Models 172, 182, and 206 series airplanes. Inadequate penetration of the weld bead may cause the weld to fail where the seat back bracket attaches to the seat base. This condition, if not corrected, could result in the seats collapsing backwards during flight with consequent loss of control. We have reviewed Cessna Service Bulletin, No. SB–7–25–04, dated April 23, 2007. The service information describes procedures for removing the seats, modifying the seat base/back attach brackets, and reinstalling the seats of all the crew seats of the affected airplanes and seats 3 and 4 on Model 206 series airplanes. FAA’s Determination and Requirements of the Proposed AD We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would require you to remove the seats, modify the seat base/back attach brackets, and reinstall the seats of all the crew seats of the affected airplanes and seats 3 and 4 on Model 206 series airplanes. Costs of Compliance We estimate that this proposed AD would affect 1,556 airplanes in the U.S. registry. We estimate the following costs to do the proposed modification: Total cost per airplane Total cost on U.S. operators $800 (for two seats) ........................................ $1,200 $1,599,600 1,234 (for four seats) ....................................... 1,954 435,742 Labor cost Parts cost For Models 172 and 182 series airplanes: 5 work-hours × $80 per hour = $400 (for two seats). For Model 206 series airplanes: 9 work-hours × 80 per hour = $720 (for four seats). Authority for This Rulemaking cprice-sewell on PROD1PC66 with PROPOSALS Relevant Service Information Regulatory Findings 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. We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation: 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.

on Model 206 series airplanes. This proposed AD results from reports of 
the seat base/back attach bracket failing where it is welded to the 
seat base. We are proposing this AD to prevent failure of the seat 
base/back attach brackets, which could result in the seats collapsing 
backwards during flight with consequent loss of control.

arguments regarding this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include the docket number, ``FAA 
2007-28433; Directorate Identifier 2007-CE-052-AD'' at the beginning of 
your comments. We specifically invite comments on the overall 
regulatory, economic, environmental, and energy aspects of the proposed 
AD. We will consider all comments received by the closing date and may

Discussion

    We have received three reports of the seat base/back bracket 
failing on Cessna Models 172, 182, and 206 series airplanes. Inadequate 
penetration of the weld bead may cause the weld to fail where the seat 
back bracket attaches to the seat base.
    This condition, if not corrected, could result in the seats 
collapsing backwards during flight with consequent loss of control.

Relevant Service Information

    We have reviewed Cessna Service Bulletin, No. SB-7-25-04, dated 
April 23, 2007. The service information describes procedures for 
removing the seats, modifying the seat base/back attach brackets, and 
reinstalling the seats of all the crew seats of the affected airplanes 
and seats 3 and 4 on Model 206 series airplanes.

FAA's Determination and Requirements of the Proposed AD

    We are proposing this AD because we evaluated all information and 
determined the unsafe condition described previously is likely to exist 
or develop on other products of the same type design. This proposed AD 
would require you to remove the seats, modify the seat base/back attach 
brackets, and reinstall the seats of all the crew seats of the affected 
airplanes and seats 3 and 4 on Model 206 series airplanes.

Costs of Compliance

    We estimate that this proposed AD would affect 1,556 airplanes in 
the U.S. registry.
    We estimate the following costs to do the proposed modification:

----------------------------------------------------------------------------------------------------------------
                                                                                  Total cost per   Total cost on

----------------------------------------------------------------------------------------------------------------
For Models 172 and 182 series airplanes: 5      $800 (for two seats)............          $1,200      $1,599,600
 work-hours x $80 per hour = $400 (for two
 seats).
For Model 206 series airplanes: 9 work-hours x  1,234 (for four seats)..........           1,954         435,742
 80 per hour = $720 (for four seats).
----------------------------------------------------------------------------------------------------------------

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 have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    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 proposed AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket that contains the proposed AD, the 
regulatory evaluation, any comments received, and other information on 
the Internet at http://dms.dot.gov; or in person at the Docket 
Management Facility between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Office (telephone (800) 647-5527) 
is located at the street address stated in the ADDRESSES section. 
Comments will be available in the AD docket shortly after receipt.
