MIL-STD-1798C
b. Serial Number MTBF - Mean Time Between Failure data captured by serial number is for individual components and is generally more reliable than fleet MTBF. The system should serially track critical parts (safety, mission), MSIs, all Bad Actors, TCIs, and special-attention components.
c. Findings during Scheduled Inspections - All findings during scheduled inspections should be stored in the system indefinitely. Display the last five discrepancies for each tail number and display a "Top Ten" WUC chart for the worst performers.
d. Mission Impaired Capability, Awaiting Parts (MICAP) - This metric is used by the MECSIP Manager to identify those parts where the supply or distribution of spares is impacting aircraft availability. The responsibility for generating and tracking MICAP normally rests outside MECSIP, and it is not the intent of MIL-STD-1798C for MECSIP to assume the responsibility for generating this data. Rather, it is understood that MECSIP can benefit through the data supplied by those generating MICAP data. It is recommended that the MECSIP Manager retrieve this data and track and analyze this data for MECSIP improvement opportunities."
e. Not Mission Capable rate (NMC) (S), (M), and (B) - Not Mission Capable is used by the MECSIP Program to indicate the discrepancy that prevents the aircraft from being Fully Mission Capable (FMC).
f. Aborts - Aborts are the results of component failures. All aborts will be investigated and the cause eliminated. Preventive maintenance will be applied where possible and/or overhaul procedures updated to ensure reliability is restored.
g. Bulletin Boards - Bulletin boards open communications between Engineering and Maintenance. The MECSIP will ensure all maintenance activities are reported in the total ownership of the weapon system. Use the bulletin boards to identify user complaints or concerns.
h. CANNs - Cannibalizations will be investigated for future preventive maintenance actions to correct the root cause.
i. PQDRs - The PQDR is a tool which can identify internal quality problems. A RAT member should lead the PQDR program; Maintenance should be encouraged to PQDR every defective part; and results should be analyzed until a satisfactory answer is provided. Poor troubleshooting techniques will also be part of the RAT's investigation.
5.5.3.2 Monitor component inspection and replacement criteria.
The inspection requirements shall establish the equipment to be inspected, its inspection schedule, and its inspection and/or replacement criteria. Inspection and replacement criteria for safety- or mission-critical components shall be periodically evaluated to determine that it is still appropriate and is adequate to maintain the integrity and safety of this equipment. The MECSIP Manager shall meet yearly with all major inspection chiefs to discuss improvements and new inspection criteria. The MECSIP Manager shall establish an electronic bulletin board to assist in the daily communication with Maintenance personnel and shall establish a list of contacts for each Field/Base. The list of required inspections requires frequent updates using data collected from operational units, personal contacts, Field/Base or Depot inspections, maintenance deficiency reports, or changes as a result of Engineering Change Proposals (ECPs).
5.5.3.2.1 WUC Manual.
The WUC Manual is the initial resource to obtain data for the analysis process. This manual must have a five-digit code for each component being monitored and the nomenclature must be
