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


## 29864 Federal Register / Vol. 77, No. 98 / Monday, May 21, 2012 / Rules and Regulations

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:



### E STIMATED 

### C OSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Internal and external inspection of

the left and right wing lower main spar caps for cracks. From 3 to 6 work-hours

× $85 per hour = From $255 to $510. Not applicable ............... From $255 to $510 ....... From $934,575 to $1,869,150.



### 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. List of Subjects in 14 CFR Part 39
