Nature and Extent of Maintenance
The DSU and GSU maintenance will be accomplished before evacuation of items to the next higher
maintenance functions of lower categories. Maintenance units may exceed their authorized scopes and functions when
authorized by the next higher maintenance support commander.
The maintenance burden categories are as follows:
Organizational Maintenance - 25%
Direct Support Maintenance - 50%
General Support Maintenance - 25%
Depot Maintenance - Only for complete overhaul or rebuild.
Operator/crew maintenance consists of daily checks, servicing and adjustments to obtain and maintain a specific
mission profile. Repair by Operator/crew is limited to minor adjustments which do not require disassembly.
Organizational Maintenance will be accomplished by adjusting or replacing accessible parts, assemblies and
modules (an item assembly, or component, which is designed to be handled as a single unit to facilitate supply and/or
maintenance) which do not require disassembly, special tools, or test equipment.
Direct Support Maintenance
Direct Support Maintenance will:
Provide quick response to "on equipment" repairs consisting of complete adjustments and replacement of
designated parts, assemblies and modules to return the end item to operation ready status.
