8.5 The costs of Reliability and Maintainability

8.5.1 Civil Aircraft Unreliability Costs

The most dramatic form of unreliability is an aircraft crash with loss of life. It is impossible to quantify the value of a human life, although some attempts have been made to put cash values on lives. Aircraft crash losses are easier to quantify in terms of replacement and loss of revenue. Insurers have to cover human and material costs, and typically charge premiums of 1% of aircraft initial cost per annum. Figure 8.8 [58] shows a simplified view of the inter-relationships between safety, reliability and maintainability. It also shows design and analysis tools that may be used to improve performance in these vital areas.
