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.

c. damage tolerance;

d. loads; and

e. stress-environmental and thermal.

These final analyses shall be developed following completion of the design/development test and analysis phase and shall be submitted in accordance with specific Program requirements. This plan shall require approval from the Procuring Activity.

5.4.22 Maintenance planning and task development.

Required maintenance actions (e.g., inspection, repair, or replacement) shall be developed and demonstrated to ensure the integrity and operability of the system for the required operational service life. Initial maintenance action requirements and times shall be based on engineering data to include updated analyses and test data in accordance with 5.4.21. These actions and times will be modified, as appropriate, according to information and experience from in-service operation.

The required maintenance action times shall be based on duty cycles and usage in accordance with the specific design criteria and system requirements. The initial maintenance plan shall be developed following completion of the design/development test and analysis phase and shall be submitted in accordance with specific Program requirements. This plan shall require approval from the Procuring Activity.

5.4.23 Airworthiness certification.

The final design analyses correlated to ground and flight testing are major steps to establish the air vehicle subsystems' airworthiness certification and are herein referred to as "certification analyses." The design analyses described in Task III shall be revised to account for differences revealed between analysis and test. The certification analyses are an important engineering source data for the operational procedures, limitations/restrictions, and maintenance requirements to ensure safe operation. Approval of the certification analyses shall constitute a critical step in achievement of airworthiness certification for the aircraft in accordance with procedures outlined in MIL-HDBK-516.

5.4.24 Identify technical needs (Task IV).

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.

5.4.25 Update MECSIP documents (including the MECSIP Master Plan).

Update MECSIP documents based on information learned during the test phase plus any other information which changed since the previous update.

5.5 (Task V, Sustainment) Force Management.

Force management includes those actions necessary to ensure that the performance, safety, reliability, and durability requirements established in Tasks I through IV are met and maintained throughout the entire life of the weapon system. The MECSIP Manager has overall responsibility to manage the health of the systems, regardless of the overhauling Depot. The MECSIP Manager shall be part of any management process that impacts the safety, suitability,
