INTRODUCTION.
This PIPER AIRCRAFT Maintenance Manual is prepared in accordance with the GAMA (General Aviation
Manufacturers Association) format. This maintenance manual is divided into various Groups which enable a
broad separation of contents (Chapters) within each group.
The various Chapters are broken down into major systems such as Electrical Power, Flight Controls, Fuel,
Landing Gear, etc. The System/Chapters are arranged more or less alphabetically rather than by precedence or
importance. All System/Chapters are assigned a number, which becomes the first element of a standardized
numbering system. Thus the element "32" of the number series 32-00-00 refers to the System/Chapter on
"Landing Gear". All information pertaining to the landing gear will be covered in this System/Chapter.
The major System/Chapters are then broken down into Sub-System/Sections. These sections are identified by
the second element of the standardized numbering system. The number "40" of the basic number series 32-40-00
is for the "Wheels and Brakes" portion of the landing gear.
The individual units within a Sub-System/Section may be identified by a third element of the standardized
numbering system, such as 32-40-01. This number could be assigned by the manufacturer to fit the coverage
requirements of the publication.
Example:
CHAPTER/SYSTEM SUB-SYSTEMS
LANDING GEAR WHEELS AND BRAKES
32-40-01
INDIVIDUAL UNITS
NOSE WHEEL REMOVAL
This manual 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-44 Parts Catalog P/N 761
663, and FAR 43 for proper utilization.
WARNINGS, CAUTIONS, and NOTES are used throughout this manual to emphasize important information.
— WARNING —
OPERATING PROCEDURES, PRACTICES, ETC., WHICH MAY RESULT IN
PERSONAL INJURY OR LOSS OF LIFE IF NOT CAREFULLY FOLLOWED.
— CAUTION —
OPERATING PROCEDURES, PRACTICES, ETC., WHICH IF NOT
STRICTLY OBSERVED MAY RESULT IN DAMAGE TO EQUIPMENT.
— Note —
An operating procedure, condition, etc., which is essential to emphasize.

AEROFICHE EXPLANATION AND REVISION STATUS
The Maintenance Manual information incorporated in this set of Aerofiche cards has been arranged in
accordance with the general specifications of Aerofiche adopted by the General Aircraft Manufacturer's
Association, (GAMA). 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.
Conversion of Aerofiche alpha/numeric code numbers:
First number is the Aerofiche card number.
Letter is the horizontal line reference per card.
Second number is the vertical line reference per card.
Example: 2J16 = Aerofiche card number two of given set, Grid location J16.
To aid in locating the various chapters and related service information desired, the following is provided:
1. A complete manual System/Chapter Index Guide is given for all fiche in this set.
2. A complete list of Illustrations is for all fiche in this set following System/Chapter Index.
3. A complete list of Charts is for all fiche in this set following list of illustration.
4. A complete list of paragraph titles and appropriate Grid location numbers is given at the beginning of each
Chapter relating to the information within that Chapter.
5. Identification of Revised Material:
Revised text and illustrations are indicated by a black vertical line along the left-hand margin of the frame,
opposite revised, added or deleted material. Revision lines indicate only current revisions with
changes, 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.
A reference and record of the material revised is included in each chapter's Table of Contents/Effectivity.
The codes used in the effectivity columns of each chapter are defined as follows:
TABLE OF CONTENTS/EFFECTIVITY CODES
Original Issue: None
First Revision: Revision Indication, ( 1R Month-Year)
Second Revision: Revision Indication, (2R Month-Year)
All subsequent revisions will follow with consecutive revision numbers
such as 3R, 4R, etc., along with the appropriate month-year
Added Subject: Revision Identification, (A Month-Year)
Deleted Subject: Revision Identification, (D Month-Year)
6. Revisions to this Maintenance Manual 761 664 issued May 1, 1978 are as follows:

AIRWORTHINESS LIMITATIONS.
GENERAL.
The airworthiness limitations is FAA approved and specifies inspections and maintenance required under Parts
43, 16 and 91.163 of the Federal Aviation Regulations.
The following limitations related to fatigue life of the airplane and its components have been established with
respect to the PA-44-l80/180T airplane:
1. The safe life of the airframe structure will be released when the information becomes available.
2. The safe life limit of the propeller blades is unlimited.
— Note —
Refer to the LIMITATIONS in the Pilot's Operating handbook and FAA Approved
Airplane Flight Manual for a detailed delineation of the flight limitations of the
airplane. The mandatory replacement time and or inspection intervals of life limited
parts are contained in Chapter 5 of this manual.
