PIPER AZTEC SERVICE MANUAL INTR ODUCTION 1. Instr uctions f or Contin ued Airw or thiness W ARNING : INSTRUCTIONS FOR CONTINUED AIRWORTHINESS (ICA) FOR ALL NON-PIPER APPROVED STC INSTALLATIONS ARE NOT INCLUDED IN THIS MANUAL. WHEN A NON-PIPER APPROVED STC INSTALLATION IS INCORPORATED ON THE AIRPLANE, THOSE PORTIONS OF THE AIRPLANE AFFECTED BY THE INSTALLATION MUST BE INSPECTED IN ACCORDANCE WITH THE ICA PUBLISHED BY THE OWNER OF THE STC. SINCE NON-PIPER APPROVED STC INSTALLATIONS MAY CHANGE SYSTEMS INTERFACE, OPERATING CHARACTERISTICS AND COMPONENT LOADS OR STRESSES ON ADJACENT STRUCTURES,THE PIPER PROVIDED ICA MAY NOT BE VALID FOR AIRPLANES SO MODIFIED. The PIPER PA-23-235/250 Aztec Service Manual constitutes the Instructions for Continued Airworthiness in accordance with Federal Aviation Regulations (FAR) Part 23, Appendix G. Section I contains the Airworthiness Limitations and the Inspection Program is in Section III. 2. Gener al This publication is prepared in PIPER proprietary format with respect to arrangement and content. W ARNING :USE ONLY GENUINE PIPER PARTS OR PIPER APPROVED PARTS OBTAINED FROM PIPER APPROVED SOURCES, IN CONNECTION WITH THE MAINTENANCE AND REPAIR OF PIPER AIRPLANES. This manual generally does not contain hardware callouts for installation. Hardware callouts are only indicated where a special application is required. To confirm the correct hardware used, refer to the PA-23-235/250 Aztec Parts Catalog, P/N 753-522, and FAR 43 for proper utilization. Genuine PIPER parts are produced and inspected under rigorous procedures to insure airworthiness and suitability for use in PIPER airplane applications. Parts purchased from sources other than PIPER, even though identical in appearance, may not have had the required tests and inspections performed, may be different in fabrication techniques and materials, and may be dangerous when installed in an airplane. Additionally, reworked or salvaged parts or those parts obtained from non-PIPER approved sources, may have service histories which are unknown or cannot be authenticated, may have been subjected to unacceptable stresses or temperatures or may have other hidden damage not discernible through routine visual or nondestructive testing. This may render the part, component or structural assembly, even though originally manufactured by PIPER, unsuitable and unsafe for airplane use. Piper Aircraft, Inc. expressly disclaims any responsibility for malfunctions, failures, damage or injury caused by use of non-PIPER approved parts. NO TE : Piper Aircraft, Inc. expressly reserves the right to supersede, cancel and/or declare obsolete any part, part numbers, kits or publication that may be referenced in this manual without prior notice. In any question concerning the care of your airplane, be sure to include the airplane serial number in any correspondence. 01/01/09 INTRODUCTION 1A7

PIPER AZTEC SERVICE MANUAL INTRODUCTION 01/01/09 1A10 7. Aer of ic he Gr id Number ing 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 numbered 1A8A and 1A8B. B. Inserting pages at the end of an Aerofiche grid row. The legacy Aerofiche grid numbering 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 numbered 1A25 and 1A26. 8. Identifying Re vised Ma ter ial A. 1981 thru April, 1986: 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. September, 1986 thru 2004: 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. 2006: A revision to a page is defined as any change to the printed matter that existed previously. Revisions, additions and deletions are identified by a vertical line (aka change bar) along the lefthand margin of the page opposite only that portion of the printed matter that was changed. A change bar in the left-hand margin opposite the footer (i.e. - section/subject, grid number and date), indicates that the text was unchanged but the material was relocated to a different page. NO TE : Change bars are not used in the title pages. Likewise, all change bars are removed when a publication is completely revised (i.e. - reissued).
