Serial Number Explanation Example: 5. Assignment of Subject Material This publication is divided into logical subject groupings based on aircraft system or task function. Refer to Section Index Guide, grid 1A16A. 6. Pagination A modified legacy Aerofiche grid numbering system (explained below) will be used to indicate location within the manual until the next complete revision. 7. Aerofiche Grid Number Piper has ceased production of all Aerofiche (i.e.,microfiche) products. The Aerofiche grid numbers will be replaced by Section page numbers (i.e. I-1, II-3, etc.) indicating the Section and the consecutive page number from the beginning of the section in the next complete revision. In the interim, as partial revisions occur, the legacy Aerofiche grid numbering system may be modified, as explained below, to simplify production. Deviations from the legacy Aerofiche grid numbering system will occur when it becomes necessary to add pages to the manual and will typically take two forms: A. Inserting pages between two existing grids in the same row. When inserting two pages between the existing grids 1A8 and 1A9, the two new pages will be number 1A8A and 1A8B. B. Inserting pages at the end of an Aerofiche grid row. The legacy Aerofiche grid number system limited page numbers in a row to a maximum of 24 (i.e., row 1A would be numbered 1A1-1A24). That limit no longer applies. Accordingly, if two pages need to be added between any existing grid row end and grid row start (i.e., 1A24 and 1B1), the new pages will simply be numberred 1A25 and 1A26. 24 671 TYPE CERTIFICATE DESIGNATION 24 = PA-24, PA-24-250, PA-24-260 26 = PA-24-400 SEQUENCE NUMBER (1 to 4 digits) PIPER COMANCHE SERVICE MANUAL INTRODUCTION 04/01/09 1A10 8. Identifying Revised Material A. 1976 thru 1982: Revised text and illustrations are indicated by a vertical line along the left-hand margin of the frame, opposite revised, added or deleted material. Revision lines indicate only current revisions with changes and additions to or deletions of existing text and illustrations. Changes in capitalization, spelling, punctuation, indexing, the physical location of the material or complete page additions are not identified by revision lines. B. 1983 thru 1997: Revised text and illustrations are indicated by a vertical line along the left-hand margin of the frame, opposite revised or added material. Revision lines indicate only current revisions with changes and additions to existing text and illustrations. Changes in capitalization, spelling, punctuation, indexing, physical location of material, or complete page additions are not identified by revision lines. C. 1998 thru 2007: A revision to a page is defined as any change to the text or illustrations that existed previously. Such revisions, additions and deletions are identified by a vertical black line (change bar) along the left- hand margin of the page opposite only the text or illusration that was changed. Changes in capitalization, spelling, punctuation, indexing, the physical location of the material or complete page additions are not identified by revision lines. D. 2009 and later: A revision to a page is defined as a change to the text or illustrations that existed previously. Revision, additions and deletions are identified by a vertical line (aka change bar) along the left- hand margin of the page opposite only the text or illustration that was changed. Reformatted, but otherwise unchanged, text is not identified by a change bar. Change bars in the section Tables of Contents do not indicate a change to that page, but rather that the information in the actual paragraph has changed A change bar in the left-hand margin opposite the footer (i.e.- chapter/section/subject, page number and date), indicates that the text was unchanged but the material was relocated to a different page. Example. NOTE: Change bars are not used in the title pages, list of illustrations, or list of tables. Likewise, when a publication is completely revised (i.e. - reissued), change bars will only appear in the Tables of Contents. 9. Indexing A Section Index Guide, below, will assist the user in locating desired information. In addition, each Section begins with an individual Table of Contents. PIPER COMANCHE SERVICE MANUAL 04/01/09 INTRODUCTION 1A11 10. Warnings, Cautions and Notes These adjuncts to the text are used to highlight or emphasize important points when necessary. Warnings call attention to use of materials, processes, methods, procedures or limits which must be followed precisely to avoid injury or death to persons. Cautions call attention to methods and procedures which must be followed to avoid damage to equipment. Notes call attention to methods which make the job easier. Warnings and Cautions shall be located directly above and Notes directly beneath the text and be in line with the paragraphs to which they apply. 11. Accident/Incident Reporting To improve our Service and Reliability system and aid in Piper’s compliance with FAR 21.3, knowledge of all incidents and/or accidents must be reported to Piper immediately. To expedite and assist in reporting all incidents and accidents, Piper Form 420-01 has been created. See Service Letter 1041 for latest revision. This procedure is to be used by all Dealers, Service Centers and Repair Facilities. 12.

Limitations (TCDS-1A15, Rev. 34.) No limitations related to fatigue life of the airplane and its components have been established with respect to the PA-24, PA24-250/260, and PA-24-400 Comanche airplane: NOTE: Refer to the LIMITATIONS section in the Aircraft Flight Manual for a detailed delineation of the flight limitations of the airplane. 1-2. Inspections Refer to Section III for Piper’s recommended Inspection Program. 1-3. Major Repairs to Life Limited Components Major repairs to areas defined in FAR Part 43, Appendix A, must be shown, using approved data, to not diminish the Life of the component as stated herein. 1-4. Life Limited Parts Marking and Disposition 14 CFR Part 45.16, Marking of Life Limited Parts requires that proper procedures are followed when removing life limited parts with time and/or cycles remaining on them as well as the disposition of life limited parts with no time and/or cycles left. Life limited parts are defined in paragraph 1, above. A. Parts that are removed prior to attaining the required time and/or cycles in service defining the useful life, are to be marked with indelible ink or marker with the part number, serial number and accumulated life status as defined in 14 CFR Part 43.10 in a manner that does not effect part structural integrity, i.e., no surface deformation such as vibration/etching allowed. B. Parts that have accumulated the life limit shall be dispositioned of in accordance with the applicable FARs. Piper recommends life limited parts with no time and/or cycles remaining be completely destroyed.
