Publications are updated by the issuance of changes and revisions. These modifications ensure that the publication is technically correct, accurate, and adequate for its intended use. Publication changes include advance change notices, permanent changes, and revisions.

Advance Change Notice

An advance change notice (ACN) permits rapid response to technical difficulties encountered in the fleet's use of a publication. Its incorporation into the publication is mandatory.

An ACN is prepared by the activity that has the responsibility for the publication. It is sent by letter or naval message, depending on the urgency and the amount of information involved. The ACN directs you to a specific chapter, section, part, page, paragraph, sentence, figure, or table and provides the exact information that must be added, substituted, or deleted.

An ACN is identified by a number and a letter, separated by a diagonal (i.e., ACN 4/C). As exemplified, the number before the diagonal (4) indicates the fourth ACN released since the last permanent change. The letter after the diagonal (C) indicates the next permanent change which, in this example, is the third.

When you receive an ACN, ensure that the title and the number are the same as those on the publication. ACN action maybe made by pen and ink, cut-and-tape insertions, or page changes. After you have completed the change, record the entry in the front of the publication on the Record of Changes page. The ACN will be incorporated into the publication's next permanent change or revision.

Permanent Change

A permanent change is prepared by the activity having cognizance of the publication. It is used to correct reported deficiencies, incorporate ACNs, add new procedures, or change existing procedures. A permanent change is a package that contains one or more complete page replacements or additions, the instructions for making the changes, a new title page, and a list of effective pages.

When you receive a permanent change, ensure that it is complete. Follow the instructions on the change sheet and remove and/or replace the affected pages. After you have made the change to the publication, record the change on the Record of Changes page and then destroy all the removed pages by following local disposal instructions.

Revision

A revision supersedes an existing edition of a publication. It is usually published when an existing publication has several permanent changes already issued and/or when an additional change would reduce the publication's usability. A revision is issued as a complete publication, or a volume of a publication, and supersedes all previous issues, ACNs, and permanent changes. When you receive a revision, the superseded publication may then be destroyed according to local disposal procedures.

TECHNICAL MANUAL DEFICIENCY/ EVALUATION REPORT

The NAVSEA (User) Technical Manual Deficiency/Evaluation Report (NAVSEA 9086/10) is used to report problems in the various publications that you use. See.

Naval messages may also be used to report an emergency technical manual (TM) deficiency. Such a case may be where a TM deficiency could possibly lead to personal harm or serious equipment damage, or it could possibly adversely affect the ship's mission. There is no set format for reporting by naval messages; however, you should include the information listed on a NAVSEA 9086/10 form.

Naval Sea Data Support Activity, Port Hueneme, California, records and monitors all TM deficiency reports to ensure timely response. Never hesitate to report a TM deficiency. This will ensure that the next issue of the TM is correct and that the next person using the TM will be working with the best information available.
