MIL-DTL-81218 Manuals, Technical: Aircraft Engine Intermediate And Depot Maintenance, Preparation Of \(Work Package Concept\)This specification covers technical manual content requirements for preparation of aircraft engine intermediate and depot maintenance instructions in work package \(WP\) format for uninstalled reciprocating and gas turbine engines, including turboprop and turboshaft. This specification also covers requirements for an intermediate maintenance manual supplement for the installation, positioning, and identification of external tubing, cabling, clamping and attaching hardware and a Sequence Control Chart \(SCC\) that graphically depicts accomplishment of complete engine repair. When specified by the requiring activity, an Illustrated Parts Breakdown \(IPB\) shall be included.

e. Publication number, date and supersedure notice, when applicable.

3.7.1.3 Middle portion. Blocks in the middle portion of the SCC shall be arranged to

identify specific tasks in the logical sequence of accomplishment. The block width shall be lined

up with the time brackets in the lower portion. The task title and number shall be the same as the

intermediate maintenance manual. The WP number shall be placed in the upper right hand

corner of each block. The work area number(s) shall be located in the lower right hand corner.

WPs which contain major engine inspection requirements shall be identified by placing an asterisk

before the WP number. Task assignments to specific crew members shall be shown at the left.

Identification of the major engine inspection asterisk shall be shown.

3.7.1.4 Lower portion. A graph coordinate for TIME shall be divided into equal vertical

increments of one hour, and each hourly increment shall be subdivided in six equal parts rated at

ten minutes each. The graph shall display the total clock hours required to process the engine and

individual tasks. In addition, the time allowed each crew member to accomplish specific tasks will

permit a computation of manhours per task. If task time is excessive and could cause the length

of the SCC to exceed 52 inches, a reduction of areas used to reflect time shall be made by

grouping large individual time lapses of more than two hours into smaller increments. The tasks

shall be listed by WP number in parentheses with the left parenthesis located at the time the task

will begin and the right parenthesis at the time the task will be completed. Blocks for engine

identification number and supervisor and crew member number shall be included at the left of the

lower portion. The lower portion shall include provisions that will permit tracking and recording

of four engines.

3.7.2 Type size. Type size shall be at least 8-point type.

3.7.3 Paper stock. The SCC shall be printed on white 50 pound paper.

3.7.4 Folded dimension. The SCC shall be folded accordion style to approximately 7 1/2 x

12 inches, and so folded that the publication number will be visible.

4. VERIFICATION

4.1 Verification. Verification shall be conducted as prescribed in the contract.

5. PACKAGING

5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in

the contract or order (see 6.2). When actual packaging of material is to be performed by DoD

personnel, these personnel need to contact the responsible packaging activity to ascertain requisite

packaging requirements. Packaging requirements are maintained by the Inventory Control Point's

packaging activity within the Military Department or Defense Agency, or within the Military
