MIL-STD-1798C
in the language the technicians use. When a component is to be time changed, serially tracked, or warranted, (i.e., in particular a safety- or mission-critical, or fail-safe component) it will be identified with a special letter or asterisk.
5.5.3.2.2 Scheduled inspection requirements and replacement schedule.
The Program Office shall establish scheduled inspections within the appropriate maintenance publications. These inspection requirements are designed to direct the attention of
maintenance personnel to components and/or areas where defects are suspected to occur as a
result of usage under normal operating conditions. Once an area is inspected and documented, the findings will be used to plan logistic and maintenance procedural support and provide coverage for routine cleaning, washing, etc. These inspections are not designed to lead to the detection of isolated discrepancies that are the result of carelessness, abuse, or poor maintenance practices. During accomplishment of the specified requirements directed by the WUC Manual, maintenance personnel should observe both the equipment being inspected and the components in the surrounding area for defects or irregularities. The replacement schedule lists components whose expected service life has been determined. The failure of these items could compromise safety, mission accomplishment, or cause the failure or condemnation of
high-value components. Items not listed in the WUC Manual will be known as "fly-to-fail" and will be replaced only when they fail a condition inspection. Any changes to the WUC Manual will entail a corresponding and mandatory change to the Reliability and Maintainability
Information System (REMIS). The MECSIP Manager will review the ES' recommended changes to the manual before any changes are made.
5.5.3.2.3 Time changes.
Once an item has met the requirements for time replacement, it must be periodically monitored to ensure the time schedule is still applicable. Safety- and mission-critical components must be changed at the specified interval of service (i.e., they cannot be allowed to fail in service). Of concern, is the potential for usage to be more severe than anticipated, which will necessitate the removal of a component earlier than expected.
5.5.3.2.4 Inspection work cards.
Inspection work cards provide the mandatory inspection requirements for the weapon platform. These work cards are prepared in checklist form and will be used in performance of inspections to ensure no item is overlooked. To afford efficient maintenance planning and assignment of work, these inspection requirements are arranged by work zones and separate work cards are used for those requirements to be accomplished by each type of mechanic or specialist. All maintenance/inspection work cards shall be reviewed periodically for accuracy especially for components classified as safety- or mission-critical. The frequency of review should be a function of the time in service. Newly deployed aircraft or aircraft with a significant mission change should hold work card reviews more frequently than aircraft with a long, stable service history. The maximum period between workcard reviews/updates shall not exceed five years.
5.5.3.2.5 Program Depot Maintenance requirements.
Depot maintenance is the most complex of all the scheduled maintenance programs. It requires the use of special test equipment, long-term storage of the aircraft, and a highly-trained workforce. Program Depot Maintenance work requirements are reviewed yearly during the Maintenance Requirement Review Board (MRRB) and each task is agreed to by all the MAJCOMs. The MECSIP Manager will be a team member of the MRRB and participate during the review. New initiatives for the PDM package must be adequately justified and should have
a risk assessment performed. Most condition assessments will be done during PDM.
