INSTRUCTIONS FOR CONTINUED AIRWORTHINESS The PIPER PA-38-112 Tomahawk Maintenance Manual constitutes the Instructions for Continued Airworthiness as required by Federal Aviation Regulations (FAR) Part 23, Appendix G. Chapter 4 contains the Airworthiness Limitations section (4-00-00) and the Inspection Program is in Chapter 5 (5-20-00). GENERAL This manual is prepared in accordance with the General Aviation Manufacturers Association (GAMA) Specification No. 2, with respect to the arrangement and content of the System/Chapters within the designated Chapter/Section-numbering system. — WARNING — USE ONLY GENUINE PIPER AIRCRAFT PARTS OR PIPER AIRCRAFT APPROVED PARTS OBTAINED FROM PIPER APPROVED SOURCES,IN CONNECTION WITH THE MAINTENANCE AND REPAIR OF PIPER AIRPLANES. 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. Reworked, salvaged or those parts obtained from non-PIPER approved sources, which the service history is unknown or cannot be authenticated, may have been subjected to unacceptable stresses or temperatures or have other hidden damage, not discernible through routine visual or usual nondestructive testing. This may render the part, component or structural assembly, even though originally manufactured by PIPER AIRCRAFT unsuitable and unsafe for airplane use. PIPER expressly disclaims any responsibility for malfunctions, failures, damage or injury caused by use of non-PIPER approved parts. — Note — PIPER 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. Any question concerning the care of your airplane, be sure to include the airplane serial number in any correspondence. EFFECTIVITY This maintenance manual is effective for PA-38-112, Tomahawk, Serial Numbers: 38-78A0001 thru 38-82A0122 SERIAL NUMBER EXPLANATION Example: Introduction Page - 1 Revised: February 28, 2002 1A4 PIPER AIRCRAFT PA-38-112 AIRPLANE MAINTENANCE MANUAL 38 84 A 0001 TYPE CERTIFICATE DESIGNATION MODEL CODE A = PA-38-112 TOMAHAWK MODEL SEQUENCE NUMBER MODEL YEAR Island Enterprises

ASSIGNMENT OF SUBJECT MATERIAL This publication is divided into industry standard, three element, numeric subject groupings as follows: A. System/Chapter - The various groups are broken down into major systems such as Environmental Systems, Electrical Power, Landing Gear, etc. They are assigned a number, which becomes the first element of the standardized numbering system. Thus, the element “28” of the number 28-40-01 refers to the chapter “Fuel”. Everything concerning the fuel system will be covered in this chapter. B. Sub-System/Section - The major systems/chapters of an airplane are broken down into subsystems. These sub-systems are identified by the second element of the standard numbering system. The element “40” of the number 28-40-01 concerns itself with the indicating section of the fuel system. C. Unit/Subject - The individual units within a sub-system/section may be identified by the third element of the standard numbering system. The element “01” of the number 28-40-01 is a subject designator. This element is assigned at the option of the manufacturer and is normally zeroed out by PIPER. Refer to Chapter/Section Index Guide, for a complete breakdown and list. The material is arranged in ascending numerical sequence. PAGINATION Within each Chapter (i.e. - 28), explained above, pages are numbered consecutively beginning with Page 1 (i.e. - Page 28-1). AEROFICHE EFFECTIVITY A. The General Aviation Manufacturers Association (GAMA) have developed specifications for microfiche reproduction of aircraft publications. The information compiled in this Aerofiche Maintenance Manual will be kept current by revisions distributed periodically. These revisions will supersede all previous revisions and will be complete Aerofiche card replacements and shall supersede Aerofiche cards of the same number in the set. The “Aerofiche Effectivity” page at the front of this manual lists the current revision for each card in this set. B. Conversion of Aerofiche alpha/numeric grid code numbers: First number is the Aerofiche card number. Letter is the horizontal row reference per card Second number is the vertical column reference per card. Example: 2J16 = Aerofiche card number two, row J, column 16. C. To aid in locating information, a complete Introduction containing the Chapter/Section Index Guide for all fiche in this set, is provided at the beginning of each aerofiche card. IDENTIFYING REVISED MATERIAL 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 along the left-hand margin of the page opposite only that portion of the printed matter that was changed. A vertical line 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.
