MAINTENANCE POLICY EVALUATION ON AIRCRAFT LAMPS AND BULBS USING OPERATIONS RESEARCH APPROACH

Abstract

The present investigation was aimed at evaluation maintenance policy for lamps used on 747 Boeing Aircraft. Some of the lamps are critical for the flight of an aircraft. For an efficient lighting, the quality of maintenance should be such that minimum grounding time is needed leading to overall savings. For efficient maintenance, two types of replacement policies of bulbs and lamps were considered (1) Individual preventive maintenance and (2) Common preventive maintenance. A model formulation was done and the model was tested with field data for four years which revealed almost similar pattern. A detailed analysis of model was done for the monthly data of the last one year. It was concluded that the maintenance policy developed for critical lamps brought savings of 63..6a oei ' dent. The methodology of analysis can be useful for lamp maintenance of any aircraft
