D-9. Maintenance (continued)
Evaluation Criteria
• Does the plan identify inter-service maintenance requirements, organic and
contractor mix, projected workloads, installation requirements and time-phasing
requirements for establishing depot repair capability
• Evaluate and assess for commonality of parts/assemblies/systems in order to
facilitate maintenance and long-term sustainability. Have COTS options been
considered
• Is the maintenance approach defined, including level of repair, and does it include
the results of the analysis to determine logical maintenance task intervals,
grouping and packaging
• Defines the actions and support necessary to ensure that the system attains the
specified operational availability (A o ) that is optimized considering RCM, CBM,
time-based maintenance and TOC.
• States specific maintenance tasks, including battlefield damage repair procedures,
to be performed on the materiel system.
• States the extent, duration and use of interim contractor support (when applicable)
and provides plans for transition to organic support.
• Defines actions and support required for materiel fielding.
• Specifies the type of repair (e.g., inspect/repair as necessary, disposal or overhaul).
• Maintenance task times have been derived for the following:
o Reliability (e.g., Weapon System Reliability [WSR], Break Rate [BR],
Component Reliability [CR], Mean Time Between Failure [MTBF]).
o Maintainability (e.g., MRT, contractual maintenance task times).
o Availability (e.g., task time limits).
o Reliability and maintainability tests.
o Performance monitoring/fault detection/fault isolation and diagnostics.
• Validation tests are conducted under representative operating conditions.
3. Testability and Diagnostics
• The testability/BIT concept is defined with the operation concept and the
maintenance concept for all levels of maintenance.
• The design contains requirements for sensors to be embedded at the appropriate
hardware levels in support of the development of a health monitoring capability.
• Design analyses (e.g., fault tree, failure modes, effects and criticality) have been
used to determine test point requirements and fault ambiguity group sizes.
• The level of repair and testability analysis is completed for each configuration
item for each maintenance level to identify the optimum mix of BIT, semiautomatic
test equipment and general-purpose test equipment.
