Section I. INTRODUCTION

2-1. Scope. This chapter provides guidelines to use to assess battlefield damage. It directs you to an expedient repair

procedure, or to the standard system TM if an expedient repair procedure for your problem doesn't exist.

2-2. General. Use this BDAR technical manual (TM) in conjunction with the operator's technical manual (TM). This

chapter explains how to use this manual to assess and fix battlefield damage that prevents equipment operation. This

chapter contains the general fault assessment tables, general troubleshooting instructions, and maintenance instructions.

General fault assessment tables, specific fault assessment tables, and detailed assessment procedures are used to locate

the damage; an expedient repair procedure tells how to fix the damage. An index of the expedient repair procedures is

located in each chapter. If you don't know or aren't sure of exactly what your problem is, use the assessment tables and

procedures to find the fault.

2-3.

Application. Perform the following steps to find and fix battlefield damages:

a. Do the Preventive Maintenance Checks and Services (PMCS) in the TM. At the same time, look for obvious

damage to the Environmental Control Unit (ECU).

b. If applicable, do the troubleshooting/repair recommended by the TM.

c. If you find the problem, determine its effect on the operation of the ECU.

d. If the problem does not affect equipment operation, the commander shall decide whether to attempt to fix the

problem or continue with the mission.

e. If the damage does affect the ECU operation, do one of the following:

(1) Replace the bad part/assembly with a good one (from supply or other source).

(2) Replace the bad part/assembly with a substitute, if one exists.

(3) Use the expedient repair procedures in this manual to repair the damage.
