[Docket No. FAA-2012-1330; Directorate Identifier 2012-CE-006-AD]
RIN 2120-AA64


Airworthiness Directives; Cessna Aircraft Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Cessna Aircraft Company (Cessna) (previously COLUMBIA or 
LANCAIR) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. This 
proposed AD was prompted by reports that during maximum braking, if the 
brakes lock up and a skid occurs, a severe oscillatory yawing motion or 
``wheel walk'' may develop, which could result in further significant 
structural damage to the airplane. This proposed AD would require 
insertions into the pilot's operating handbook (POH) and the airplane 
maintenance manuals (AMM) regarding proper use of the brakes and 
inspection of the aft fuselage. We are proposing this AD to correct the 
unsafe condition on these products.

DATES: We must receive comments on this proposed AD by February 4, 
2013.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to

[[Page 75591]]

an address listed under the ADDRESSES section. Include ``Docket No. 
FAA-2012-1330; Directorate Identifier 2012-CE-006-AD'' at the beginning 
of your comments. We specifically invite comments on the overall 
regulatory, economic, environmental, and energy aspects of this 
proposed AD. We will consider all comments received by the closing date 
and may amend this proposed AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this proposed AD.

Discussion

    We have received several reports of structural damage to Cessna 
Models LC41-550FG and LC42-550FG airplanes due to ``wheel walking'' 
anomalies. These incidents were all precipitated by pilots applying 
maximum braking at high speeds, leading to locked wheels and prolonged 
tire skidding. The main landing gear struts developed a severe 
oscillatory yawing motion or ``wheel walking'' as the airplane 
decelerated.
    This ``wheel walking'' motion resulted in significant structural 
damage to the aft fuselage skin, affecting the inside skin and adjacent 
structure near the leading edge of the horizontal stabilizer. This 
condition, if not corrected, could result in further significant 
structural damage to the airplane.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require insertions into the pilot's 
operating handbook (POH) and the airplane maintenance manuals (AMM) 
regarding proper use of the brakes and inspection of the aft fuselage.

Costs of Compliance

    We estimate that this proposed AD affects 726 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

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 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 this 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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.
