1.3 Manual Revisions

This MM utilizes chapter-level revision control. Each page of the manual contains a revision indication

in the lower, inside corner. Revision indicators are consistent throughout an entire chapter, but may

vary from chapter to chapter.

A major release of the manual is called an “Issue”. The issue letter and its effective date are listed on

the title page of the manual using a letter code; for example, “Issue A”.

Updates and changes to the manual are called “Revisions” and are designated using an issue prefix

followed by a number; for example, “Revision A2” is the second revision of “Issue A”. These revisions

are listed on the Record of Manual/Handbook Revisions page near the front of the handbook. Owners

are responsible for keeping this page updated when handbook revisions are issued by ICON.

Updates and changes to chapters of the manual are called “Changes” and are designated using the

issue prefix followed by a number; for example, “Change A0” is the original release of a chapter in Issue

A and “Change B3” is the third revision of a chapter in Issue B of the entire manual. The “List of Effec-

tive Chapters” near the front of the manual documents the applicable chapter “Changes” associated

with a given manual revision.

Revisions to this Maintenance Manual will be distributed to all owners of relevant aircraft registered

with ICON. Distribution will be of the entire manual with any necessary instructions. Revisions should

be examined immediately upon receipt.

It is the responsibility of the owner to maintain this MM in a current state when it is being used for oper-

ational purposes. Owners should contact ICON whenever the revision status of their MM is in question.
