Functional Inspection. Physical operation of an item to
determine whether or not it will function in a prescribed manner.
This type of inspection uses specialized diagnostic equipment and
operational test stands. The item may be checked with a MOC while
installed on an aircraft if test equipment is not available. The
test will duplicate, as close as possible, the conditions under which
the item will operate in flight.
Component Overhaul. Maintenance performed to restore an item
to a serviceable condition, at a depot level facility, as prescribed
in the appropriate Depot Maintenance Work Requirement (DMWR). The
item is subjected to a complete disassembly and inspection. All
defective or excessively worn parts are replaced with new or
reconditioned items. When a TC item is overhauled a new service life
will start. This action will "zero" Time Since Overhaul, but not
Time Since New.
k. Component Repair. Maintenance performed to restore an item to
serviceable condition by correcting a specific failure or
unserviceable condition. This allows a TC or RC item to complete its
cycle. This action will not "zero" Time Since New or Time
1. Component Rebuild/Remanufacture. Maintenance performed to
restore an item to a like new condition in appearance, performance,
and life expectancy. This is done by complete disassembly,
inspection, and repairing or replacing all worn or unserviceable
elements with new parts or parts that have been reworked to original
manufacturing specifications. When an item is rebuilt/remanufactured
it starts a new life cycle. This action will "zero" Time Since New,
and Time Since Overhaul.
a. Maximum utilization of programmed operating hours is necessary
for economic operation of Army aircraft. Instructions in this
section have been established to achieve this objective without
b. All items listed in TB l-1500-341-01 (Aircraft Components
Requiring Maintenance Management and Historical Data Reports) or the
ULLS-A Component Legitimate Code files are considered managed items;
listed items per DA Pamphlet 738-751. DA Form 2410 component data
will be submitted to AMCOM.
Components or parts not identified as TC or RC items in the
overhaul and retirement schedule of the applicable aircraft (-23)
maintenance manual are considered condition change (CC) components.
CC items will be replaced only when they become unserviceable. All
items listed in TB l-1500-341-01 or the ULLS-A Component Legitimate
Code files, will have historical data maintained and processed per DA
