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

d.   Nondestructive inspections to be performed to support damage tolerance requirements (The ASIP Nondestructive Inspection Requirements Review Board [NDIRRB] as required by MIL-STD-1530, will include MECSIP representation);

e.   Acceptance/proof tests for individual parts, as required;

f.        Material procurement specifications and process specifications to ensure critical parts have the required properties (e.g., strength, fracture toughness, fatigue);

g.   Requirements for material/part traceability for parts which require special processing and fabrication operations; and

h.   All vendor and supplier controls for these items.

Economic trade studies shall be conducted to ensure the effective application, development, and implementation of this plan.  Environmental and usage parameters for PHM that critically affect service life should be identified within the plan.  The Product Integrity Control Plan shall

be one of the primary data items submitted under the MECSIP and shall be subject to Procuring

Activity approval.

5.2.17  Identify Technical needs (Task II).

MECSIP Managers shall make a listing of Technical Needs encountered on an annual basis.  A compiled list, from all programs, will be discussed/finalized at the MECSIP Technical Interchange Meeting and submitted into the Service-specific Research Laboratory as candidate developmental Technical Needs.

5.2.18  Update the MECSIP Master Plan.

In addition to updates to any information which has changed since the previous submission, add the following:

a.   List the classification for each MECSIP Component.

b.   Controls planned for all components that will not be allowed to fail in-service (including the safety analysis if a Risk Based Approach was used).

c.   Where applicable, identify the technical, and logistical, rationale for selecting a design service life that is most practical.

d.   Identify the time-phased scheduling and integration of system development tasks which support performance and integrity requirements for the equipment being acquired.

e.   The Corrosion Prevention and Control Plan (Reference 5.2.1.)

f.    The Environmental Emissions analysis (Reference 5.2.2.)

g.   Identification of physical and operational interfaces (Reference 5.2.3.)

h.   Design Service Life Usage (Reference 5.2.4.)

i.    Supportability planning (Reference 5.2.5.)

j.    Identify environmental and usage parameters for PHM that affect service life. (Reference

5.2.6.)

k.   Failure Modes Effects and Criticality Analysis (Reference 5.2.7.)

l.    Hazard Analysis (Reference 5.2.8.)

m.  Product Integrity Control Plan (Reference 5.2.16.)
