Airworthiness Directives; Cessna Aircraft Company (Type 
Certificate Previously Held by Columbia Aircraft Manufacturing) Models 
LC40-550FG, LC41-550FG, and LC42-550FG Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) to revise 
AD 2007-07-06, which applies to certain Cessna Aircraft Company (type 
certificate previously held by Columbia Aircraft Manufacturing) 
(Cessna) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. AD 
2007-07-06 currently requires the following: Adding information to the 
limitations section of

[[Page 64877]]

the airplane flight manual (AFM); repetitively inspecting the aileron 
and the elevator linear bearings and control rods for foreign object 
debris, scarring, or damage; and taking all necessary corrective 
actions. Since we issued AD 2007-07-06, Cessna has issued a new service 
bulletin that contains procedures for installing an access panel to 
facilitate the required inspections. Consequently, this AD retains the 
actions currently required in AD 2007-07-06; allows installing access 
panels; and changes the serial number applicability. We are issuing 
this AD to prevent jamming in the aileron and elevator control systems, 
which could result in failure. This failure could lead to loss of 
control.

DATES: This AD becomes effective on December 5, 2008.
    On December 5, 2008, the Director of the Federal Register approved 
the incorporation by reference of Cessna Mandatory Service Bulletin SB-
07-002D, dated May 29, 2008, and Cessna Mandatory Service Bulletin SB-
07-018, dated May 29, 2008, listed in this AD.
    As of April 9, 2007 (72 FR 15822, April 3, 2007), the Director of 
the Federal Register approved the incorporation by reference of 
Columbia Mandatory Service Bulletin SB-07-002, dated March 14, 2007, 
listed in this AD.

SUPPLEMENTARY INFORMATION:

Discussion

    On August 1, 2008, 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 Cessna Models LC40-550FG, LC41-550FG, and LC42-
550FG airplanes. This proposal was published in the Federal Register as 
a notice of proposed rulemaking (NPRM) on August 7, 2008 (73 FR 45902). 
The NPRM proposed to revise AD 2007-07-06 with a new AD that will 
retain the actions currently required in AD 2007-07-06; allow 
installing access panels; and change the serial number applicability.

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 1,495 airplanes in the U.S. 
registry.
    We estimate the following costs to do the inspection:

----------------------------------------------------------------------------------------------------------------
                                                                                                     Total cost
                   Labor cost                                 Parts cost               Total cost      on U.S.
                                                                                      per airplane    operators
----------------------------------------------------------------------------------------------------------------
4 work-hours x $80 per hour = $320..............  Not applicable....................         $320      $478,400
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do the optional access panel 
installation:

------------------------------------------------------------------------
                                                             Total cost
             Labor cost                    Parts cost       per airplane
------------------------------------------------------------------------
14 work-hours x $80 per hour =       Not applicable.......       $1,120
 $1,120.
------------------------------------------------------------------------

    Warranty credit for installing the access panel may be given to the 
extent noted in Cessna Mandatory Service Bulletins SB-07-018, dated May 
29, 2008.

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

[[Page 64878]]

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-
2007-27628; Directorate Identifier 2007-CE-025-AD'' in your request.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the Federal Aviation Administration amends part 39 of the Federal 
Aviation Regulations (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 removing Airworthiness Directive (AD) 
2007-07-06, Amendment 39-15011 (72 FR 15822, April 3, 2007), and adding 
the following new AD:

2007-07-06 R1 Cessna Aircraft Company (type certificate previously 
held by Columbia Aircraft Manufacturing): Amendment 39-15713; Docket 
No. FAA-2007-27628; Directorate Identifier 2007-CE-025-AD.

Effective Date

    (a) This AD becomes effective on December 5, 2008.

Affected ADs

    (b) This AD revises AD 2007-07-06, Amendment 39-15011.

Applicability

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

------------------------------------------------------------------------
                 Model                             Serial Nos.
------------------------------------------------------------------------
LC40-550FG............................  40001 through 40079.
LC41-550FG............................  41001 through 41800 and 411001
                                         through 411041.
LC42-550FG............................  42001 through 42569 and 421001
                                         through 421006.
------------------------------------------------------------------------

Unsafe Condition

    (d) This AD is the result of reports of possible foreign object 
contamination of the linear bearings. We are issuing this AD to 
prevent jamming in the aileron and elevator control systems, which 
could result in failure. This failure could lead to loss of control.
