A. Revision
The data in the revision column is comprised of two elements:
(1) A Type of Revision Code: ORG = Original, CR = Complete Revision, and PR = Partial
Revision.
NOTE: Partial Revisions (PR) are listed only until the next Complete Revision (CR) is published.
Then they are removed.
(2) The Revision Date in YYYYMMDD format.
NOTE: The Revision Date is the date placed on each revised page. It exists to separate one
version of a page from another. Revision Date does not indicate the calendar date when
the revision was actually published and available to the public. However, this is the date
that appears in the Current Revision Checklist in the Customer Service Information
File.
B. Publication Date
Publication Date usage has varied over the years. 1974–1996 is unknown. 1997–2013 it generally
was synchronized with the revision date regardless of when the revision was published. In mid 2013
and later, the Publication Date is the calendar date when the revision was actually published and
available to the public.
NOTE: This date does not appear in the Current Revision Checklist in the Customer Service
Information File.

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-34-200T Seneca II 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. General
This publication is prepared in PIPER proprietary format with respect to arrangement and content.
WARNING: 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-34-200T Parts Catalog, P/N 761-589, 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.
NOTE: 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
1A9
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 Revised Material
A. 1979 thru 1985:
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 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. 1986 thru 2006:
Revised text and illustrations are indicated by a black vertical line along the left-hand margin of the
frame, opposite revised or added material. Revision lines indicate only current revisions with
changes or additions to 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.
C. 2007:
Revisions, additions and deletions are identified by a vertical line (i.e., change bar) along the left-
hand margin of the page opposite only that portion of the printed matter that was changed. Changes
in capitalization, spelling, punctuation, indexing, physical location of material, or complete page
additions are not identified by revision lines.
D. 2009 and later:
A revision to a page is defined as a change to the text or illustrations that existed previously.
Revisions, additions and deletions are identified by a vertical line (aka change bar) along the left-
hand margin of the page opposite only the text or illustration that was changed. Reformatted, but
otherwise unchanged, text is not identified by a change bar.
Change bars in the section Tables of Contents do not indicate a change to that page, but rather that
the information in the actual paragraph has changed.
A change bar 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.
NOTE: Change bars are not used in the title pages. Likewise, when a publication is completely
revised (i.e. - reissued), change bars will only appear in the Tables of Contents.

9. Indexing
A Section Index Guide, below, will assist the user in locating desired information. In addition, each
Section begins with an individual Table of Contents.
10. Warnings, Cautions and Notes
These adjuncts to the text are used to highlight or emphasize important points when necessary. Warnings
call attention to use of materials, processes, methods, procedures or limits which must be followed
precisely to avoid injury or death to persons. Cautions call attention to methods and procedures which
must be followed to avoid damage to equipment. Notes call attention to methods which make the job
easier.
11. Accident/Incident Reporting
To improve our Service and Reliability system and aid in Piper’s compliance with FAR 21.3, knowledge
of all incidents and/or accidents must be reported to Piper immediately. To expedite and assist in
reporting all incidents and accidents, Piper Form 420-01 has been created. See Service Letter 1041 for
latest revision. This procedure is to be used by all Dealers, Service Centers and Repair Facilities.
