Abstract:
The Special Flight Services is a division of Saudi Arabian Airlines – SAUDIA,that operates small private jet aircrafts to serve government top officials and its distinguishedguests, as well as charter flights for business companies. The SFS division has experiencedlately a serious problem called AOG or Aircraft On Ground, which is the inability of theaircraft to fly due to a technical problem caused by the unavailability of the required spareparts to fix it. This paper summarizes the study that was conducted to resolve this problem.The goals of the study were to minimize the frequency of the AOG occurrences and to reducethe average AOG duration when they occur. The procurement and Stores departments werestudied and their processes were analyzed to determine the root causes of the problem. Therepair cycle of the spare parts was reengineered to make it shorter and more efficient; thecritical spare parts were identified, their demand and their optimal stock quantity wereestimated. The existing repair cycle was reduced from a total of 23 activities taking anaverage total time of 149 days to only 15 activities requiring an average repair time of 30days; an enhancement of almost 80% in average repair time was achieved by reengineeringthe repair cycle. Seventeen critical parts were identified and few additional numbers of eachpart were needed to be on stock. These measures improved the problem and made it withinacceptable normal level.
