Life-cycle Costing

This study will analyze a large clay of literature to confirm keep growth as a function of age . Validating these perceived maintenance increases and defineing the logical implication of this trend is necessary to accurately forecast future comprise of ownershipStatement of the ProblemToday no Life Cycle Cost mildew attempts to quantify the rate of airframe maintenance cost increases due to the effects of ageing . MIL-HDBK-1530 defines maturement aircraft as the point in time in which the aircraft : 1 has over flown it s design service goal , 2 ) is corroded , or 3 ) has reached the time of onset of general fatigue damage (WFD . It is further characterized as the point at which twain the cost and operational burden associated with repairing fatigue , wearing away , and stress corrosion cracking (SCC ) either by themselves or in combination result in a solid departure from a newly manufactured aircraft Today no industry recognized cost escalation factors exist which represent airframe maintenance cost increases due to aging Figure 2 .

How Aircraft ageing May Relate to Flight Safety , Aircraft Availability , and second Costs (Kim et al , 2005The cost to maintain and operate aging aircraft is being reviewed to identify factors , which must be acknowledged in the methodology to accurately assess the economic service demeanor of aging aircraft . Recent GAO reports have been critical of increases in both depot maintenance man-hours (cost ) and duration (downtime ) of military aircraft . These GAO reports have associated these increases with the irreversible effects of aging (General Accounting Office , 1996To accurately prognosticate the Economic Service Life of an aircraft one must model aging considerations , and compare those costs to the costs of acquiring and in operation(p) an alternative aircraft . Aging fleet maintenance requirements must be also combined with estimates to upgrade outdated avionics . These plans may include navigational upgrades required to comply...If you want to get a entire essay, order it on our website: Orderessay
