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. List all existing waivers and/or flight limitations associated with MECSIP parts on the specific aircraft.

The intent of the tracking program is to capture the history from cradle to grave for each aircraft being monitored. Additionally, this tracking program will enable the Maintenance superintendents, MAJCOMs, and Program Engineering to know immediately the remaining service life for each life limited part using serial tracking, and history of major repairs for each aircraft.

5.5.2.7 Develop a system to track enroute and/or deployed system reliability.

The Program Office shall develop a system to track the discrepancies at the enroute/deployed bases and, when trends allow, implement preventive maintenance actions. To accomplish this, the system should be looking at the NMC status (Supply (S), Maintenance (M), or Both (B))and When Discovered Codes (WDCs).

5.5.2.8 Develop a program to track MICAP hours assessed to each component.

The Program Office shall develop a program to track Mission Impaired Capability, Awaiting Parts (MICAP) data. The system should capture this data and display it by MICAP hours and number of aircraft disabled for X amount of days.

A MICAP condition occurs when parts must be shipped from lateral storage facilities, in combination with at least one of the following conditions:

1. Supply does not have enough spares in the system to satisfy scheduled/unscheduled maintenance; or

2. Supply does not have the capability to produce spares to keep up with demand (i.e., manpower, facilities, parts, poor scheduling); or

3. Maintenance is improperly troubleshooting the system and replacing parts at an unexpected pace.

5.5.2.9 Develop a program to capture CANN actions by WUC.

The Program Office shall develop a program to capture CANN actions by WUC. This aids in understanding the "whole picture" for each component.

5.5.2.10 Develop a program to identify and monitor MSIs.

The Program Office shall develop a program to identify and monitor MSIs. Maintenance Significant Items are those items selected by the Program, due to economic or operational impact to the Maintenance community (see section 3 for complete definition). The Program shall collect data and recommend candidates for inclusion in the MSI listing during PIWG meetings. The Program shall collect and correlate data from all sources (i.e., G081, MICAPS,

Awaiting Parts (AWP) documentation, NMC (S/M/B), PQDRs). Components which require Time

Compliance Technical Order (TCTO) control or weapon system compatibility shall be classified as "MSI" and serially tracked. Components discovered to have a major impact on operational reliability or maintenance resources shall be compiled and presented to the annual PIWG conference for special tracking. Items approved by the PIWG will be classified as MSIs. If serial tracking and/or historical documentation is required for USAF programs, the -06 WUC Manual shall be annotated to alert Maintenance; and the -6, Special Inspections Technical Order, shall be annotated to require an AFTO Form 95 Historical Document. Additionally, each item shall receive a risk assessment (AFPAM 90-902), which includes a FMECA.
