Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This emergency AD was sent previously to all 
known U.S. owners and operators of these airplanes. This AD requires 
obtaining written approval from the Manager, Wichita Aircraft 
Certification Office (ACO), to operate the airplane. This written 
approval must clearly state that operation is approved per Emergency AD 
2010-26-54. This AD was prompted by a Cessna Model LC41-550FG airplane 
that suffered a significant structural failure in the wing during a 
production acceptance flight test. We are issuing this AD to prevent 
catastrophic failure of the wing due to disbonding of the wing skin 
from the wing spar.

DATES: This AD is effective January 10, 2011 to all persons except 
those persons to whom it was made immediately effective by Emergency AD 
2010-26-54, issued on December 17, 2010, which contained the 
requirements of this amendment.
    We must receive comments on this AD by February 24, 2011.

ADDRESSES: You may send comments by any of the following methods:

SUPPLEMENTARY INFORMATION:

Discussion

    On December 10, 2010, we issued Emergency AD 2010-26-53, which 
requires obtaining written approval from the Manager, Wichita ACO, to 
operate the airplane. The written approval must clearly state that 
operation is approved per Emergency AD 2010-26-53. This action was 
prompted by a Cessna Model LC41-550FG airplane that suffered a 
significant structural failure in the wing during a production 
acceptance flight test. The wing skin disbonded from the upper forward 
wing spar. The length of the disbond was approximately 7 feet.
    Since issuing AD 2010-26-53, we determined the need to increase the 
serial numbers in the Applicability section and to correct a serial 
number in the Applicability section. We issued Emergency AD 2010-26-54, 
dated December 17, 2010, which retains the actions of the previous AD, 
adds serial numbers to the Applicability section, and corrects a serial 
number in the Applicability section.
    This condition, if not corrected, could result in catastrophic 
failure of the wing due to disbonding of the wing skin from the wing 
spar.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires obtaining written approval from the Manager, 
Wichita ACO, to operate the airplane. The written approval must clearly 
state that operation is approved per Emergency AD 2010-26-54.

Interim Action

    We consider this AD interim action.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
disbonding of the wing skin from the wing spar could result in 
catastrophic failure of the wing. Therefore, we find that notice and 
opportunity for prior public comment are impracticable and that good 
cause exists for making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2010-1297 and 
Directorate Identifier 2010-CE-068-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. We will 
consider all comments received by the closing date and may amend this 
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 AD.

Costs of Compliance

    We estimate that this AD affects 13 airplanes of U.S. registry.
    There are no labor or parts costs associated with this AD action.

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

    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 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.
