A modified legacy Aerofiche grid numbering system (explained below) will be used to indicate location
within the manual until the next complete revision.
7. Aerofiche Grid Number
Piper has ceased production of all Aerofiche (i.e.,microfiche) products. The Aerofiche grid numbers will
be replaced by Section page numbers (i.e. I-1, II-3, etc.) indicating the Section and the consecutive page
number from the beginning of the section in the next complete revision. In the interim, as partial
revisions occur, the legacy Aerofiche grid numbering system may be modified, as explained below, to
simplify production.
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
number 1A8A and 1A8B.
B. Inserting pages at the end of an Aerofiche grid row.
The legacy Aerofiche grid number 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 numberred 1A25 and 1A26.
