[Docket No. 2000-CE-75-AD; Amendment 39-12211; AD 2001-09-06]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration, DOT.
 ACTION: Final rule; request for comments.
 SUMMARY: This amendment adopts a new airworthiness directive (AD) that applies to certain Cessna Aircraft Company (Cessna) Models 206H and T206H airplanes. This AD requires you to visually inspect the horizontal stabilizer attachment reinforcement brackets for the existence of seam welds and replace any reinforcement bracket found without seam welds. This AD is the result of a report that these parts were manufactured without seam welds. The actions specified by this AD are intended to detect and replace structurally deficient horizontal stabilizer attachment brackets. Continued use of such brackets could result in structural failure of the horizontal stabilizer with reduced or loss of control of the airplane.
 DATES: This AD becomes effective on May 18, 2001. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation as of May 18, 2001. The Federal Aviation Administration (FAA) must receive any comments on this rule on or before June 15, 2001.
 ADDRESSES: Submit comments in triplicate to FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2000-CE-75-AD, 901 Locust, Room 506, Kansas City, Missouri 64106. You may get the service information referenced in this AD from Cessna Aircraft Company, Product Support, P.O. Box 7706, Wichita, Kansas 67277; telephone: (316) 517-5800; facsimile: (316) 942-9006. You may examine this information at FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2000-CE-75-AD, 901 Locust, Room 506, Kansas City, Missouri 64106; or at the Office of the Federal Register, 800 North Capitol Street, NW, suite 700, Washington, DC.

SUPPLEMENTARY INFORMATION: Discussion *What events have caused this AD?*
                     Cessna recently notified FAA of a defect in the manufacturing of the horizontal stabilizer attachment reinforcement brackets. Cessna manufactured certain reinforcement brackets without seam welds. The seam welds help provide the required structural integrity for the horizontal stabilizer attachment bracket. *What are the consequences if the condition is not corrected?*
                     This condition, if not corrected, could result in structural failure of the horizontal stabilizer with reduced or loss of control of the airplane. *Is there service information that applies to this subject?*
                     Cessna has issued Service Bulletin SB00-55-03, dated August 28, 2000. This service bulletin includes procedures for: —visually inspecting the right and left horizontal stabilizer attachment reinforcement brackets for the existence of seam welds along the lower inboard and outboard wall/flange; and —removing and replacing the horizontal stabilizer assemblies with new parts. The FAA's Determination and an Explanation of the Provisions of This AD *What has FAA decided?*
                     The FAA has reviewed all available information, including the service information referenced above; and determined that: —The unsafe condition referenced in this document likely exists on Cessna Models 206H and T206H airplanes within the listed serial number range; —The actions specified in the previously-referenced service information (as specified in this AD) should be accomplished on the affected airplanes; and —AD action should be taken in order to correct this unsafe condition. *What does this AD require?*
                     This AD requires you to accomplish the actions previously specified in accordance with Cessna Service Bulletin SB00-55-03, dated August 28, 2000. *Will I have the opportunity to comment prior to the issuance of the rule?*
                     Because the unsafe condition described in this document could result in structural failure of the horizontal stabilizer with possible reduced or loss of control of the airplane, FAA finds that notice and opportunity for public prior comment are impracticable. Therefore, good cause exists for making this amendment effective in less than 30 days. Comments Invited *How do I comment on this AD?*
                     Although this action is in the form of a final rule and was not preceded by notice and opportunity for public comment, we invite your comments on the rule. You may submit whatever written data, views, or arguments you choose. You need to include the rule's docket number and submit your comments in triplicate to the address specified under the caption 
                    **ADDRESSES**
                    . We will consider all comments received on or before the closing date specified above. We may amend this rule in light of comments received. Factual information that supports your ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether we need to take additional rulemaking action. *Are there any specific portions of the AD I should pay attention to?*
                    The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to 
                    ( print page 21279)
                    modify the rule. You may examine all comments we receive before and after the closing date of the rule in the Rules Docket. We will file a report in the Rules Docket that summarizes each FAA contact with the public that concerns the substantive parts of this AD. We are reviewing the writing style we currently use in regulatory documents, in response to the Presidential memorandum of June 1, 1998. That memorandum requires federal agencies to communicate more clearly with the public. We are interested in your comments on whether the style of this document is clear, and any other suggestions you might have to improve the clarity of FAA communications that affect you. You can get more information about the Presidential memorandum and the plain language initiative at 
                    *http://www.plainlanguage.gov.* *How can I be sure FAA receives my comment?*
                    If you want us to acknowledge the receipt of your comments, you must include a self-addressed, stamped postcard. On the postcard, write “Comments to Docket No. 2000-CE-75-AD.” We will date stamp and mail the postcard back to you. Regulatory Impact *Does this AD impact various entities?*
                    These regulations 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. Therefore, FAA has determined that this final rule does not have federalism implications under Executive Order 13132. *Does this AD involve a significant rule or regulatory action?*
                    The FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and is not a significant regulatory action under Executive Order 12866. It has been determined further that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If it is determined that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory evaluation will be prepared and placed in the Rules Docket (otherwise, an evaluation is not required). A copy of it, if filed, may be obtained from the Rules Docket. List of Subjects in 14 CFR Part 39 Air transportation
