INTRODUCTION
INTRODUCTION
1. INSTRUCTIONS FOR CONTINUED AIRWORTHINESS.
WARNING : 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-34-200 Seneca Service Manual constitutes the Instructions for Continued Airworthiness.
Section I contains the Airworthiness Limitations and the Inspection Program is in Section III.
2. GENERAL.
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.
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.
THE NEW PIPER AIRCRAFT, INC. expressly disclaims any responsibility for malfunctions, failures,
damage or injury caused by use of non-PIPER approved parts.
NOTE : THE NEW 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.

microfiche reproduction of aircraft publications. The information compiled in this Aerofiche Service
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.

(2) A complete subject Index for all fiche in this set.
8. 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.
Example.
9. INDEXING.
An alphabetically arranged subject Index follows this introduction to assist the user in locating desired
information. In addition, each System/Chapter begins with an individual Table of Contents.
