MIL-DTL-81928 Manuals, Technical: Aircraft Maintenance Instructions, Technical Content Requirements \(Work Package Concept\)This specification covers the technical content requirements for the preparation of technical manuals in work package concept for the maintenance of aircraft and related systems. The manuals include an integrated illustrated parts breakdown \(IPB\). The general style and format requirements of technical manuals in work package \(WP\) format are contained in the general specification \(MIL-DTL-81927\).

b. Depth and scope of coverage requirements. The testing and troubleshooting procedures

are determined by the complexity of the test requirements, either complex or non-

complex. The complexity of the test requirements is determined by the task analysis.

3.3.2.3.5 Operational checkout (testing) requirements:

a. Operational circuit tests. Maximum use of operational circuits shall be made using the

appropriate support equipment and:

(1) Built-in tests,

(2) Power supply and power distribution indications,

(3) Functional modes of operation, and

(4) All available controls and indicators.

b. Test sequence. The operational checkout shall be sequenced to establish:

(1) An increasing confidence in the circuit/unit under test.

(2) That passing previous test ensures proper input requirements for the test being

performed.

(3) A logical entry point for fault isolation.

(4) A fault isolation entry point for each test indication.

(5) That successful completion of the operational checkout verifies proper operation.

c. Fault isolation reference methods. A fault isolation entry point may reference:

(1) Logic text format. Combined testing and troubleshooting (logic text) format:

(a) "Yes" or "No" column entries should only reference another procedural step.

(b) A procedural step may reference appropriate action, including separate fault

isolation procedures.
