Abstract:
As aircraft fleets get older, the challenge of Flight Safety gets greater. This Thesis focus on management strategies and principles to keep long-life fleet safe and effective into old age. But the safety and efficacy are not the only ones who are considered at long-life fleet. Here the question arises why the aircraft prior to exposure to the effects of rising life expectancy, are not replaced by other aircraft.The reason is the high cost of the replacement. Aircraft are expensive to design and manufacture. In commercial aviation, extreme competition and miniscule profit force pressures to delay replacement of older aircraft with expensive new types. But in Military aircraft reason for delaying replacement of older aircraft is different. In addition to the cost of replacing military aircraft, sanctions, and lack of suitable alternatives are important factors for delaying replacement of older military aircraft. So in addition to safety and efficacy, economics debate is complementary targets for extending the life of the aircraft. In This thesis, suitable strategies for aging aircraft in terms of safety, economic and management is given
