INTRODUCTION
1. General
A. The information in this publication is based on data available at the time of publication and is
updated, supplemented, and automatically amended by all information issued in Service News
Letters, Service Bulletins, Supplier Service Notices, Publication Changes, Revisions, Reissues and
Temporary Revisions. All such amendments become part of and are specifically incorporated within
this publication. Users are urged to keep abreast of the latest amendments to this publication
through information available at Cessna Authorized Service Stations or through the Cessna Product
Support subscription services. Cessna Service Stations have also been supplied with a group of
supplier publications which provide disassembly, overhaul, and parts breakdowns for some of the
various supplier issued revisions and service information which may be reissued by Cessna’s
Authorized Service Stations and/or through Cessna’s subscription services.
WARNING: All inspection intervals, replacement time limits, overhaul time
limits, the method of inspection, life limits, cycle limits, etc.,
recommended by Cessna are solely based on the use of
new, remanufactured, or overhauled Cessna approved parts. If
parts are designed, manufactured, remanufactured, overhauled,
purchased, and/or approved by entities other than Cessna, then
the data in Cessna’s maintenance/service manuals and parts
catalogs are no longer applicable and the purchaser is warned
not to rely on such data for non-Cessna parts. All inspection
intervals, replacement time limits, overhaul time limits, the
method of inspection, life limits, cycle limits, etc., for such
non-Cessna parts must be obtained from the manufacturer
and/or seller of such non-Cessna parts.
2. Coverage
A. The Cessna Single Engine Structural Repair Manual is prepared in accordance with the Air
Transport Association Specification 2200 for Manufacturers’ Technical Data.
B. This Structural Repair Manual contains material identification for structure subject to field repair;
typical repairs applicable to structural components; information relative to material substitution and
fastener installation; and a description of procedures that must be performed with structural repair,
such as protective treatment of the repair and sealing.
C. This manual will serve as a medium through which all single engine operators will be advised of
actual repairs. As service records indicate a requirement, this manual will be revised to include
additional specific repairs.
3. Airplane Identification
A. To identify structural differences to associated airplanes, the specific airplane identity may appear
in the figure and the text. Items not identified for a specific airplane or group of airplanes are suitable
for all airplanes.
4. Aerofiche (microfiche)
A. The Structural Repair Manual is prepared for Aerofiche presentation in addition to 8 ½ by 11 inch
loose leaf manual format. To facilitate the use of the aerofiche, a list of chapters with an aerofiche
frame reference has bee tabulated and incorporated into the Introduction of the Structural Repair
Manual.
B. Aerofiche is a microform reproduction of the contents of the 8 ½ by 11 inch manual in a form
convenient for service areas. An aerofiche reader is required to view the 4-inch by 6-inch aerofiche
card. Each aerofiche card contains 12 horizontal rows of 24 images each. An image displays
information equal to an 8 ½ by 11 inch loose leaf page and represents a frame. Horizontal rows
are lettered from A at the top to L at the bottom. Vertical columns are numbered 1 to 24. The
combination of a letter and a number identifies a frame (image) in the aerofiche card. The List of
Chapters provides a quick reference to information contained in the aerofiche.
5. Using the Structural Repair Manual or Aerofiche
A. Division of Subject Matter.
(1) Structural repair information is divided into chapters in accordance with Air Transport
Association Specification 100. Each Chapter is further subdivided to provide individual or
related structural member presentation.
(2) Chapter 51 provides general structural information required to perform a repair. Also included
in Chapter 51 are general repair procedures that may be accomplished in noncritical areas.
B. Effectivity Page.
(1) A list of effective pages is provided with each chapter. All pages listed are active and shall
appear in sequence as recorded in the Effectivity Page.
(2) The Effectivity Page contains tabular listing of ATA number, page and date of each page in
that chapter. A change in the chapter requires a revision to the chapter’s Effectivity Page.
The date corresponds to the date that appears on the individual page which defines when
that page was issued.
C. Page Numbering System.
(1) The Structural Repair Manual or corresponding aerofiche page numbering system consists
of the Air Transport Association Specification 100 three element numbers separated by
dashes. The page number and date are printed immediately to the right of the three element
number. The three element number is assigned to a component, with the first set of numbers
corresponding to the ATA-100 assigned chapter number.
(2) The page number complies with Air Transport Association Specification 100 for subdividing a
Structural Repair Manual. Blocks of sequential page numbers are used to identify:
Pages 1 Through 100 - Structural Identification
Pages 101 Through 199 - Allowable Damage
Pages 201 through 999 - Repair Procedures
(3) The date which appears below the page number signifies when the page was issued. If no
revisions to that page have occurred, the date signifies original date.
(4) Illustrations use the same figure numbering as the page block in which they appear. For
example: Figure 202 would be the second figure in a repair procedure.
6. Revision (Manual)
A. Regular Revision.
(1) Pages to be removed or inserted in the Structural Repair Manual are controlled by the
Effectivity Page. Pages are listed in sequence by the three element number and then by page
number.When two pages display the same three element number and page number, the page
displaying the most recent Date of Page Issue shall be inserted into the Structural Repair
Manual. The date column on the corresponding chapter Effectivity Page shall verify the active
page.
B. Temporary Revision.
(1) For paper publications:
(a) Temporary revision pages are filed in the Structural Repair Manual by replacing existing
pages in the manual. File the temporary revision cover page according to the filing
instructions on the Temporary Revision Cover Page.
(2) For aerofiche publications:
(a) Draw a line through any aerofiche frame (page) affected by the Temporary Revision
with a permanent red ink marker. This will be a visual identifier that the information on
the frame (page) is no longer valid and the Temporary Revision should be referenced.
for "added" pages in a temporary Revision, draw a vertical line between the applicable
frames which is wide enough to show on the edges of the pages. Temporary Revisions
should be collected and maintained in a notebook or binder near the aerofiche library
for quick reference.
7. Identifying Revised Material
A. Additions or revisions to text in an existing section will be identified by a revision bar in the left
margin of the page and adjacent to the change.
B. When additions or revisions are made to text in an existing section, all pages displaying the same
three element number shall also display the same Date of Page Issue. The date column on the
corresponding chapter Effectivity Page shall verify the active page. These pages will display the
current revision date in the Date of Page Issue location.
C. When extensive technical changes are made to text in an existing section that requires extensive
revision, revision bars will appear the full length of text.
D. When art is revised or added, a change bar will appear on the full length of the page.
