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.

5.5.1 Subtask 1: Data gathering and task planning.

This group of tasks is necessary when no previous MECSIP Program existed. These tasks should already be complete if a robust MECSIP Program was in place during the development phase.

5.5.1.1 Establish a Reliability Analyses Team (RAT).

The Program Office shall establish a RAT within the Engineering department to analyze field reliability, maintainability and availability metrics. (The next three sentences apply only to USAF programs: Air Force Materiel Command Instruction (AFMCI) 63-1201, Implementing

Operational Safety Suitability and Effectiveness (OSS&E) and Life Cycle Systems Engineering, assigns the Chief Engineer the sole engineering responsibility for the weapon system and in effect gives him/her final authority over any component being used on the weapon system. This includes all supply, procurement, and maintenance facilities involved with any component repair/overhaul. Depots, Major Commands (MAJCOMs), and Using Activities act as key advisors for many areas, but the final decisions rest with the Chief Engineer.) The Chief Engineer will typically designate the MECSIP Manager to act on his/her behalf for matters involving the management of the weapon platform functional systems. To accomplish this task, the MECSIP Manager will establish a RAT to assist him/her in developing a system management program. Establishment of a RAT composed of the proper mix of personnel is instrumental to a cost-effective life cycle management program. The program will typically be Worldwide Web-based and only be available on the secure military network. The program shall track and provide alert monitoring for all safety- and mission-critical components. Recommended metrics for monitoring are as follow:

a. identify serially-tracked components;

b. confirm that inspection and replacement intervals and life limits for all safety- and mission-critical components is current and documented in the appropriate technical orders;

c. monitor the MTBF for all safety- and mission-critical components;

d. list the "Top Ten" for each of the following categories: economic, maintenance, and supply Not Mission Capable (NMC) components;

e. provide a method to perform Preview and in-depth analysis;

f. provide a tail number management system;

g. monitor the CANNs for each Work Unit Code (WUC);

h. monitor the Mission Impaired Capability, Awaiting Parts (MICAPs) for each WUC;

i. monitor findings at scheduled inspections;

j. monitor the enroute and/or deployed base component failures;

k. monitor aborts by WUC;

l. provide an electronic bulletin board for each shop to improve communications;

m. provide a program to assist in performing risk assessments and failure modes evaluations; and

n. monitor PHM sensors and track trends in real time.
