Airworthiness Directives; Cessna Aircraft Company Models 172R, 
172S, 182S, 206H, and T206H Airplanes

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 172R, 172S, 
182S, 206H, and T206H airplanes. This AD requires that you accomplish 
the following:

--Inspect the oil pressure switch to determine if the oil pressure 
switch is part-number (P/N) 77041 or P/N 83278; and
--Replace any P/N 77041 oil pressure switch with a P/N 83278 switch.

    This AD is the result of reports of failure of the oil pressure 
switch diaphragm. The actions specified by this AD are intended to 
prevent loss of engine oil through the failure of the oil pressure 
switch diaphragm, which could result in partial or complete loss of 
engine power.

DATES: Effective March 11, 2000.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the regulation as of March 
11, 2000.

SUPPLEMENTARY INFORMATION:

Discussion

    What events have caused this AD?: We have received three reports of 
the diaphragm of the oil pressure switch failing on Cessna Modesl 172R, 
182S, and 206H airplanes. The part number (P/N) of the failed oil 
pressure switch is 77041. The P/N 77041 oil pressure switch is utilized 
on the following Cessna airplanes:
      

------------------------------------------------------------------------
               Model                             Serial Nos.
------------------------------------------------------------------------
172R..............................  17280001 through 17280830.
172S..............................  172S8001 through 172S8324, 172S8326
                                     through 172S8333, 172S8340,
                                     172S8342, 172S8344, 172S8345, and

                                     and T20608145.
------------------------------------------------------------------------

    What are the consequences if the condition is not corrected?: 
Failure of the engine oil pressure switch diaphragm results in loss of 
engine oil through the vent hole. This could lead to partial or 
complete loss of engine power.

Relevant Service Information

    Is there service information that applies to this subject?: Yes. 
Cessna has issued Service Bulletin No. SB00-79-01, dated January 31, 
2000.
    What are the provisions of this service bulletin?: The service 
bulletin specifies and includes procedures for accomplishing the 
following:

--Inspecting the oil pressure switch to determine if the oil pressure 
switch is P/N 77041 or P/N 83278; and
--Replacing any P/N 77041 oil pressure switch with a P/N 83278 switch.

[[Page 8650]]

The FAA's Determination and an Explanation of the Provisions of the 
AD

    What has the FAA decided?: After examining the circumstances and 
reviewing all available information related to the incidents described 
above, including the relevant service information, the FAA has 
determined that:

--An unsafe condition exists or could develop on Cessna Models 172R, 
172S, 182S, 206H, and T206H airplanes;
--The actions of the above-referenced service bulletin should be 
accomplished on the affected airplanes; and
--AD action should be taken in order to prevent loss of engine oil 
through the failure of the oil pressure switch diaphragm, which could 
result in partial or complete loss of engine power.


    What does this AD require?: This AD requires you to accomplish the 
following:

--Inspect the oil pressure switch to determine if the oil pressure 
switch is P/N 77041 or P/N 83278; and
--Replace any P/N 77041 oil pressure switch with a P/N 83278 switch.

    What is the compliance time of this AD?: Within the next 25 hours 
time-in-service (TIS) after the effective date of this AD.
    Will the public have the opportunity to comment prior to the 
issuance of the rule?: No. Since a situation exists that requires the 
immediate adoption of this regulation, the FAA finds that notice and 
opportunity for public prior comment hereon are impracticable, and that 
good cause exists for making this amendment effective in less than 30 
days.

Comments Invited

    Although this action is in the form of a final rule and was not 
preceded by notice and opportunity for public comment, the FAA invites 
comments on this 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. The FAA will consider all comments received on or 
before the closing date. 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.
    The FAA is re-examining 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 clearer, 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 <a href="http://www.plainlanguage.gov">http://www.plainlanguage.gov</a>.
    The FAA specifically invites comments on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to 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.
    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-07-AD.'' We will date stamp and mail 
the postcard back to you.

Regulatory Impact

    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, the FAA has determined that 
this final rule does not have federalism implications under Executive 
Order 13132.
    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.
