2-1. SCOPE.
a. This chapter provides guidelines
to use in assessing battlefield damage
to the OH-58 helicopter. It directs you
to an expedient BDAR fix or to the stan-
dard system fix of TM 55-1520-228-23-1,2
if an expedient BDAR repair does not
exist.
General decision logic chart,
Table 2-1, assists in BDAR discussions.
b.
Each chapter will have a specific
fault assessment chart for each func-
tional group and this flow chart will
direct you to specific BDAR fixes for
and within the functional group.
c. Use the following guidelines to
find and fix sustained damage or
suspected damage to your helicopter.
Keep in mind that damage can be
sustained while on the ground or in
flight.
The helicopter location can
have a considerable effect on the
assessment.
The following appraisal
shall be accomplished.
(1) If possible and time permits,
inspect and check the helicopter using
operator’s check list (CL), operator’s
manual (-10), and other records and
forms kept in aircraft log book. At
the same time be looking for obvious
damage to aircraft.
INTRODUCTION
(2) If applicable and possible,
use standard troubleshooting recommen-
dations in TMs.
(3) If you find a problem, deter-
mine its effect on helicopter’s mobi-
lity and capability.
(4) If you cannot fix the problem
with standard fixes, apply this TM and
use general and specific assessment
tables, charts, and BDAR action.
(5) If the damage does not affect
aircraft’s flying status, the aircraft
or flight commander will decide whether
to fix or defer fix, and continue or
start mission.
(6) If damage does affect flight
status, do one of the following:
(a) Replace damaged part with a
serviceable part.
(b) Replace damaged part with
suitable substitute if it exists.
(c) Apply a BDAR fix.
(7) After repairing the damage,
replace all lost fluids/lubricants. If
one specified by aircraft TM is not
available, refer to Appendix D for
alternative materials/parts.
