Federal Register Abstract
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.

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

2010-26-54, issued on December 17, 2010, which contained the
requirements of this amendment.

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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>, 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.
