NAVAIRINST 4120.11
IETM Implementation Guidance
1. The following guidance is provided for the use of MIL-STD-
3001, MIL-M-81310, and International Standard S1000D. These
standards shall be used when acquisition of NAVAIR TMs is a
requirement, or when converting of legacy TMs to XML. Figure 1
provides a flowchart of the decision process for selecting the
proper IETM Specification.
a. S1000D shall normally be used for:
(1) All ACAT I and II programs.
(2) Major weapons systems/equipment TMs going through
major revisions/updates (i.e. when requiring an update to
approximately 80% of the manual and not already in a digital
format stated in reference (c).
(3) Converting major weapons systems/equipment TMs that
have more than 10 years of operations and sustainment remaining.
(4) When the required functionality of the IETM is not
obtainable using the MIL-STD-3001 Tool Kit.
(5) Future development or enhancement requirements
include use of a non-linear database.
(6) If a business case analysis or cost/benefit analysis
shows S1000D to be the most cost-effective alternative (i.e.,
Foreign Military Sales distribution or interoperability).
b. S1000D may not be the best choice for maintenance card
decks, NATOPs, or NATIPs. Programs should review the
specification carefully to determine if it will support their
requirements for these types of data.
c. MIL-STD-3001 shall normally be used for Weapons
systems, aeronautical equipment, engines, airborne
weapons/equipment, and support equipment when the business case
does not justify the use of S1000D.
d. MIL-M-81310 shall normally be used for weapons
loading/WAMs manuals if S1000D does not support.
e. S1000D and MIL-STD-3001 shall not be used for Legacy
TMs when there is no return on investment or improvement in
maintenance capability gained by conversion. In these
instances, updates and revisions should be prepared in
accordance with the applicable specifications and then converted
to a PDF format.
