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 separationof 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-
4-00 is for the "Wheels and Brakes" portion of the landing gear.
The individual unitswithin 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:
