Section 3: MAINTENANCE MANAGEMENT
3.1
Maintenance Philosophy. The purpose of a maintenance management system is to
ensure the maximum availability of any given system at a minimum cost in man-hours of funds.
"Availability" and "costs" are relative terms; they must be interpreted for each facility. The
maintenance of Visual and Air Navigational Lighting Systems is an integral part of aviation
maintenance performed at DOD shore installations. Maintenance of the navigational lighting
systems is a mission essential part of air operations. Maintenance operations must be scheduled
and coordinated with the fleet or MAJCOM air operational exercises and training missions.
The maintenance operations include maintenance planning, preventive maintenance inspection,
visual inspection, repair, installation, and calibration, and unscheduled maintenance procedures.
Maintenance procedures including the work order and documentation required may vary
between activities. The purpose of this document is to provide the minimum maintenance
procedures required for safe and efficient movement of aircraft during takeoff, landing, and
taxiing operations.
In addition, operational factors are a major consideration in determining what maintenance is
required. Facilities with heavy traffic may require more frequent maintenance servicing than
those used only by light traffic.
Regardless of the actual maintenance routines decided upon, the following elements are essential
to any controlled maintenance program. The maintenance procedures in this handbook are
considered minimum guidelines. Check with the local authority for additional guidance and
related DOD manuals and instructions to ensure there is not a conflict with these procedures.
a) Documenting the service checks that comprise the maintenance program.
b) Recording the performance of each maintenance action, scheduled or unscheduled.
3.2
Maintenance Schedule. Documenting the maintenance schedule by spelling out each
item of routine maintenance is beneficial in several ways.
a) It allows planned allocation of man-hours to the maintenance function.
b) It helps to establish spare part stock levels.
c) It identifies the necessary maintenance routines to new employees, decreasing
training time needed for system familiarization.
d). It identifies to management the scope of the maintenance task in terms of man-
hours and materials requirements.
3.3
Maintenance Records. Maintenance records are an important part of an effective
maintenance management system. They provide a service history of each piece of equipment,
ensure regular maintenance without duplication of effort, and give a data base for statistical
analysis of lighting system performance. Without records, knowledge gained from regular
inspections will not be retained, and preventive maintenance will be difficult. An effective
