required, the procedure(s) should be referenced.
3.3.2.3.7 Manual test procedures.
a. Pre-test setup procedures. Pre-test setup procedures, including pre-test setup illustrations,
as required, e.g. test equipment interconnection diagram.
b. Testing and troubleshooting procedures. Testing and troubleshooting procedures may be
integrated into one procedure using "Logic Text format" or :
(1) Separate testing (operational checkout), using logic tree format procedural text with
fault isolation entry points established to reference;
(2) Separate troubleshooting (fault isolation) procedures based on the operational
checkout established entry points. Troubleshooting (fault isolation) procedures may
be provided a format that will give the most effective presentation.
c. Post-test teardown procedures.
3.3.2.3.8 Troubleshooting procedures using semi-automatic or automatic test equipment.
Many high performance systems have been designed to accept the use of semi-automatic/
automatic test equipment. These systems are designed and programmed for rapid electronic test
in the interest of reducing maintenance downtime to fault isolate and repair. The following
procedures apply:
a. Automatic testing requires the same basic test information as described in 3.3.2.3.1 and
3.3.2.3.6 above with minor exceptions.
b. Testing set-up procedures and troubleshooting criteria defined in separate manuals shall
not be duplicated.
c. Reference should be made to other documents containing the automated test information.
d. A schematic of the system/component under test shall be prepared to support the
non-automated test capability in the event of automatic test equipment nonavailability, or
failure. The schematic shall contain an indication of all test points and the appropriate
input and output signals.
3.3.2.3.9 Testing and troubleshooting using built-in-test equipment. Built-in-test capabilities
are designed to operate in various formats. One of these is built-in-test using preprogrammed
magnetic test tapes; another is the incorporation of electronically controlled sensors within the
systems to be tested.
3.3.2.3.9.1 Built-in-test using preprogrammed magnetic tape or software. Testing
