MIL-STD-1798 Mechanical Equipment And Subsystems Integrity ProgramThe purpose of this standard is to describe the general process to achieve and maintain the physical and functional integrity of the mechanical elements of aircraft systems. The goal of this integrity program is to achieve the desired level of safety and aircraft availability at the most economic cost across the life cycle of the weapon system. This standard allows the process to be tailored in a competitive environment to meet specific equipment, subsystem, and/or system requirements. The Mechanical Equipment and Subsystems Integrity Program MECSIP is implemented in the planning process and continued until retirement of the system.

MIL-STD-1798C

5.5.5.2.2 Supply drawdown.

The drawdown in the supply system shall be planned, such that spares will be available as needed. Cannibalizations from depot condition "F" assets, Aerospace Maintenance and Regeneration Group (AMARG) pulls, and reuse of components (repairs instead of overhauls) can provide spares in the event new spares are not available. Installation and usage records of in-service components will be relied upon for replacement actions. Should the option of AMARG pulls be utilized, the configuration of those items pulled should be updated to the current configuration prior to installation.

5.5.5.2.3 Establish liaisons at Primary Bases.

Each Base that hosts or maintains the weapon platform shall be required to provide a liaison for

Maintenance and Supply to the MECSIP Manager. The liaisons at the Primary Bases will advise the Retirement IPT regarding updates to both maintenance procedures and source of

supply (new, repaired versus overhaul, and AMARG pulls).

6. NOTES.

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)

6.1 Intended use.

Mechanical equipment and subsystems which provide power, control, and other contributory functions are essential elements of weapon systems. This standard is intended to be used to establish programmatic tasks for the development, acquisition, modification, operation, and sustainment of the mechanical elements of airborne, support, and training systems developed to perform combat and combat-support missions in environments unique to military weapon systems.

6.2 Acquisition requirements.

Acquisition documents should specify the following:

a. Title, number, and date of this standard.

6.3 Data requirements.

When this standard is used in an acquisition which incorporates a DD Form 1423, Contract Data Requirements List (CDRL), the data requirements identified below may be developed as specified by an approved Data Item Description and delivered in accordance with the approved CDRL. When the Defense Federal Acquisition Regulation Supplement (DFARS) exempts the requirement for a DD Form 1423, the data specified below may be deliverable by the contractor in accordance with the contract requirements. The deliverable data may include:

Paragraphs Data Requirements Title

5.1.8, 5.2.18, 5.3.12, 5.4.25, and 5.5 MECSIP Master Plan

5.2.9 and 5.5.1.4 Safety-Critical and Mission-Critical Components List

5.2.16 Product Integrity Control Plan

5.4.21 Final integrity analysis

5.4.22 Maintenance planning and task development.

The ASSIST database should be researched at https://assist.dla.mil/quicksearch/ to ensure only current and approved DIDs are cited on the DD Form 1423.
