[Docket No. FAA-2012-0534; Directorate Identifier 2012-CE-015-AD; 
Amendment 39-17053; AD 2012-10-04]
RIN 2120-AA64

Airworthiness Directives; Cessna Aircraft Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Cessna Aircraft Company Models 210G, T210G, 210H, T210H, 210J, T210J, 
210K, T210K, 210L, T210L, 210M, T210M, 210N, T210N, P210N, 210R, T210R, 
and P210R airplanes. This AD requires an inspection(s) of the left and 
right wing lower main spar caps for cracks and either replacing cracked 
wing lower main spar caps, wing spars, or wings (as applicable) with 
serviceable spar caps, spars, or wings that are found free of cracks or 
incorporating an FAA-approved modification. This AD also requires 
reporting the results of the inspections to the FAA. This AD was 
prompted by reports of cracks found in the wing lower main spar caps on 
the above-referenced airplanes with cantilever metal wings. We are 
issuing this AD to correct the unsafe condition on these products.

DATES: This AD is effective June 5, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of June 5, 2012.
    We must receive comments on this AD by July 5, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion

    We received reports of cracks found in the wing lower main spar 
caps on Cessna Aircraft Company Models 210G, T210G, 210H, T210H, 210J, 
T210J, 210K, T210K, 210L, T210L, 210M, T210M, 210N, T210N, P210N, 210R, 
T210R, and P210R airplanes with cantilever metal wings. The reports 
include a wing lower main spar cap that was completely severed with the 
skin split. This condition, if not corrected, could result in 
structural failure of the wing with consequent loss of control.

Relevant Service Information

    We reviewed Cessna Aircraft Company Single Engine Service Letter 
SEL-57-01, Revision 1, dated May 9, 2012. The service letter describes 
procedures for visually inspecting the right and left lower main spar 
caps for cracks and replacing the spar cap, wing spar, or wing, as 
applicable.

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 a one-time internal (for all airplanes) and 
external (for certain airplanes) visual inspection of the left and 
right wing lower main spar caps for cracks and either replacing cracked 
wing lower main spar caps, wing spars, or wings, or incorporating an 
FAA-approved modification. This AD also requires reporting the results 
of the inspections to the FAA, Wichita ACO.

Interim Action

    We consider this AD interim action. We are requiring inspection(s) 
of the left and right wing lower main spar caps with a report to the 
FAA of the results. We will work with the type certificate

[[Page 29864]]

holder to evaluate that information to determine repetitive inspection 
intervals and subsequent terminating action. Based on this evaluation, 
we may initiate further rulemaking action to address the unsafe 
condition identified in this AD.

FAA's Justification and 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 
cracks in the wing lower main spar caps could result in structural 
failure of the wing during flight with consequent loss of control. 
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-2012-0534 and 
Directorate Identifier 2012-CE-015-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 3,665 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

                                   to $510.
----------------------------------------------------------------------------------------------------------------

    Currently, there is no FAA-approved modification for a cracked wing 
lower main spar cap. If cracks are found during the inspections 
required by this AD, further flight is prohibited until an FAA-approved 
modification is incorporated or the cracked wing lower main spar cap is 
replaced with a serviceable spar cap, wing spar, or wing (as 
applicable) if one is available. The FAA does not have availability and 
cost information on serviceable spar caps, wing spars, or wings. 
Therefore, at this time, the FAA has no way of determining any on-
condition costs associated with replacing or modifying cracked wing 
lower main spar caps.

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.

following in accordance with Cessna Single Engine Service Letter 
SEL-57-01, Revision 1, dated May 9, 2012:
    (i) Before further flight after June 5, 2012 (the effective date

and WS 45.00 for cracks.
    (ii) If no cracks are found during the inspection required in 
paragraph (g)(1)(i) of this AD, within the next 5 hours TIS after

    If cracks are found during the inspections required in 
paragraphs (g)(1)(i), (g)(1)(ii), (g)(2), or (g)(3) of this AD, 
before further flight after the inspection in which cracks are 
found, either replace the cracked part (spar cap, wing spar, or
