Application of Weibull Distribution Method for Aircraft Component Life Estimation in Civil Aviation Sector

The continuous monitoring of fleet reliability has been made compulsory by the aviation authorities, due to the maintenance program for civil aviation aircrafts has been prepared on MSG-3 philosophy. In this context, task card and maintenance intervals must be set according to the reliability of aircraft components and systems. Approximately 90 percent of the maintenance programs prepared according to the MSG-3 philosophy contain task cards for finding defects or faults, and these do not have a relevant use in the absence of a defect or fault. In this study, reliability of the aircraft parts is estimated according to the Weibull distribution by using maintenance data, and the probability of failure for each part is calculated. 
