OPNAV INSTRUCTION 4400.9D
From: Chief of Naval Operations
Subj: DEPOT LEVEL REPAIRABLE ITEM MANAGEMENT
Ref: (a) OPNAVINST 4441.12D
(b) OPNAVINST 4614.1G
(c) CJCSI 4110.01E (NOTAL)
(d) DoD Directive 4151.18 of 31 Mar 2004
(e) OPNAVINST 4790.14B
1. Purpose
a. To provide policy and assign responsibilities for the management of depot-level
repairables (DLR).
b. Major changes to this revision include the clarification that this instruction does not apply
to the inventory management of strategic weapons systems items managed by Director, Strategic
Weapons Programs (DIRSSP) and clarification of management of non-installed DLRs on-hand
and maintenance assistance modules (MAMS).
2. Cancellation. OPNAVINST 4400.9C.
3. Scope. This instruction applies to all activities that manage, use, process, repair, or control
DLRs (i.e., principal and secondary items with material control codes E, G, H, Q, or X, with the
exception of cognizance symbol 6RX). This instruction does not apply to the inventory
management of strategic weapons system items managed by DIRSSP.
4. Background. The evolution of sophisticated maintenance philosophies and supply
management procedures for DLRs has paralleled the increased acquisition of complex weapons
systems and equipment. These complex weapons systems and equipment contain numerous
repairables which are costly to procure. It is generally more economical to repair defective
components and restore them to ready for issue condition than to procure replacements.
Intensive management of these repairables is essential for improving fleet readiness in the most
effective manner.
5. Policy. Repairables management will optimize the fulfillment of repair cycle requirements
for DLRs and ensure adequate visibility and control of non-installed DLRs. Subparagraphs 5a
through 5m support this general policy.
