equipment, and related support equipment \(SE\). The manuals will normally include an integrated illustrated parts breakdown \(IPB\).

Pages 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 - 11 - 12 - 13 - 14 - 15 - 16 - 17 - 18 - 19

MIL-DTL-81919C(AS)

i. IPB. IPBs and GAPLs shall appear in the same WP as procedural maintenance steps.

Procedural maintenance steps will utilize the IPB illustration. Other maintenance

illustrations may be required where a critical measurement, dimension, alignment, or

inspection location must be identified to facilitate assembly. Minimum acceptable

technical content is as follows:

(1) The IPB shall include parts provisioned for the applicable maintenance level(s)

support of the item.

(2) An organizational level IPB shall contain and illustrate items replaceable at the

organizational level that do not affect the integrity of equipment provisioned for

complete repair at a higher level of maintenance, for example: knobs, lens covers,

light bulbs, reflectors, and fuses. These items will also be listed and illustrated in the

appropriate level of maintenance data in accordance with the complete repair code

assigned.

(3) Source documentation shall determine the scope and depth of coverage required.

SM&R codes will be assigned by the government and shall be listed in the IPB to

identify the source of spares, repair parts, and SE and the levels of maintenance

authorized to maintain, repair, overhaul, or condemn them.

j. Illustrations. Illustrations shall be prepared in accordance with MIL-DTL-81927 and the

specific technical content requirements specified herein.

(1) IPB illustrations. IPB illustrations shall be prepared in accordance with MIL-DTL-

81927 and either MIL-DTL-81929 or MIL-DTL-15014, as applicable. When

separate IPB manuals are authorized by the contract, the maintenance procedures

shall not reference the separate IPBs. Separate maintenance illustrations shall be

developed using, to the maximum amount possible, the separate IPB illustrations.

Refer to MIL-DTL-81927 (Multiple use of illustrations) and either MIL-DTL-81929

or MIL-DTL-15014, as applicable.

(2) Separate maintenance illustrations. When separate maintenance illustrations are

required, they shall be reproductions of illustrations prepared for the IPB except for

marginal copy, figure numbers, and titles. The layout of illustrations shall take into

consideration the possible dual usage. Clarity of maintenance instructions shall be the

prime consideration. Reproduction of all "parts" of an IPB figure, when only one or

more "parts" of the total illustration is required, is not acceptable. The reproduction

shall also be modified as required for clarity, for example, removal of index numbers

and leader lines not used in maintenance. Additional illustrations required for support

of procedures shall be prepared, when required for clarity.
