[Docket No. 2000-CE-75-AD; Amendment 39-12211; AD 2001-09-06]
RIN 2120-AA64


Airworthiness Directives; Cessna Aircraft Company Models 206H and 
T206H Airplanes

<BD>AGENCY: <RM>Federal Aviation Administration, DOT.

<BD>ACTION: <RM>Final rule; request for comments.

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

<BD>SUMMARY: <RM>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.

<BD>DATES: <RM>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.

<BD>ADDRESSES: <RM>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

<BD>SUPPLEMENTARY INFORMATION:

<RM>Discussion

    <IT>What events have caused this AD? <RM>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.
    <IT>What are the consequences if the condition is not corrected? 
<RM>This condition, if not corrected, could result in structural 
failure of the horizontal stabilizer with reduced or loss of control of 
the airplane.
    <IT>Is there service information that applies to this subject? 
<RM>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

    <IT>What has FAA decided? <RM>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.

    <IT>What does this AD require? <RM>This AD requires you to 
accomplish the actions previously specified in accordance with Cessna 
Service Bulletin SB00-55-03, dated August 28, 2000.
    <IT>Will I have the opportunity to comment prior to the issuance of 
the rule? <RM>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

    <IT>How do I comment on this AD? <RM>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 <BD>ADDRESSES<RM>. 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.
    <IT>Are there any specific portions of the AD I should pay 
attention to? <RM>The FAA specifically invites comments on the overall 
regulatory, economic, environmental, and energy aspects of the rule 
that might suggest a need to

[[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 <IT><a href="http://www.plainlanguage.gov">http://www.plainlanguage.gov</a>.
    How can I be sure FAA receives my comment? <RM>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

    <IT>Does this AD impact various entities? <RM>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.
    <IT>Does this AD involve a significant rule or regulatory action? 
<RM>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.
