Original legacy operative paragraph

Source publication: 1998-12-02 · Document 98-32045. Independent observation edition: selected-ad-source-text-extension-3.0.0.

This paragraph is newly retained from the same immutable official publication. It is a legacy §39.13 amendment and the publication’s own AD header, not a newly invented Affected ADs heading. The earlier observation edition remains unchanged.

    2. Section 39.13 is amended by adding a new airworthiness directive 
(AD) to read as follows:

98-24-14  Cessna Aircraft Company: Amendment 39-10923; Docket No. 
98-CE-111-AD.

UNKNOWN historical relationship: adding a new entry does not establish that no earlier directives are affected. No explicit historical replacement statement was established in this bounded operative paragraph.

Applicability text in this publication

    Applicability: The following airplane models and serial numbers, 
certificated in any category, that are equipped with any WYE tube, 
part number (P/N) 9910299-25 or P/N 9910299-26, in the engine 
exhaust system:

------------------------------------------------------------------------
                Model                            Serial numbers
------------------------------------------------------------------------
340A.................................  215 through 1817.
414A.................................  1 through 1212.
------------------------------------------------------------------------

    Note 1: This AD allows the aircraft owner or pilot to check the 
maintenance records to determine whether any WYE tube, P/N 9910299-
25 or P/N 9910299-26, has been installed in the engine exhaust 
system between May 8, 1998, and December 21, 1998 (the effective 
date of this AD). See paragraph (c) of this AD for authorization.
    Note 2: Cessna is considering issuing service information 
pertaining to this subject. This AD takes precedence over any 
existing or future service information on this subject.
    Note 3: This AD applies to each airplane identified in the 
preceding applicability provision, regardless of whether it has been 
modified, altered, or repaired in the area subject to the 
requirements of this AD. For airplanes that have been modified, 
altered, or repaired so that the performance of the requirements of 
this AD is affected, the owner/operator must request approval for an 
alternative method of compliance in accordance with paragraph (d) of 
this AD. The request should include an assessment of the effect of 
the modification, alteration, or repair on the unsafe condition 
addressed by this AD; and, if the unsafe condition has not been 
eliminated, the request should include specific proposed actions to 
address it.
