PURPOSE

This Maintenance Guidance Material (MGM) provides recommended guidelines for maintenance of airport visual aid installations and electrical systems. Efficiency and safety of operation at an airport can only be expected from systems that are in good operational condition. Proper maintenance is the only key to keep the installations and facilities of an airport in good condition. Maintenance also minimizes wear and tear, thus controlling and extending considerably the life span of technical components. In this respect, maintenance becomes an economic requirement to keep investment and capital costs for the

aeronautical infrastructure within acceptable limits.

The manual is intended to give guidance to aerodrome operators on scheduling and conducting maintenance work on the airport. The guidance developed based on related ICAO documents, which, in turn, were developed from various airport operators' practices and reflects long‐term experience in the field of airport operation. Since wear and sensitivity of any technical component depend on material, utilization, age, climate and other environmental conditions. Maintenance work shall plan based on local needs, experience and recommendations of manufacturers of components and be carried out as per the approval of the appropriate authority.
