1-1. PURPOSE.
Damage Assessment and Repair (BDAR) is
to quickly return the disabled heli-
copter to the operational commander by
expediently fixing, bypassing, or jury-
rigging components to restore the mini-
mum essential systems required for the
support of the specific combat mission
for self-recovery. These repairs will
be temporary and may not restore full
performance capability. Standard repair
will be completed as soon as practical.

This TM pro-
be a complete catalog of all possible
emergency repairs. The repairs described
here will serve as guidelines and will
stimulate the experienced mechanic/
operator to devise repairs as needed to
rapidly return equipment to operation in
a combat situation.
d. The direct replacement of a piece
of equipment by its spare, even under
battlefield conditions, is not a BDAR
fix and may not be covered is in this
TM.
A standard procedure should be per-
formed in preference to a BDAR fix when
time and spares are available.
1-3. APPLICATION.
a. The procedures in this manual are
designed for battlefield environments
and should be used in situations where
standard maintenance procedures are
impractical. These procedures are not
meant to replace standard maintenance
practices, but rather to supplement them
strictly in a battlefield environment.
Standard maintenance procedures will
provide the most effective means of
returning damaged equipment to ready
status provided that adequate time,
replacement parts, necessary tools, and
trained/qualified repair persons are
available. BDAR procedures are only
authorized for use in an emergency
situation in a battlefield environment,
and only at the direction of the com-
mander. They are not to be continued
after the equipment is out of the battle
environment.
