Abstract
A new approach to structural reliability analysis based on order statistics is introduced by considering the expected time to the first failure in a fleet of specified magnitude. Because in the design of large structural units, such as transport aircraft, failure of even a single unit must be prevented, reliability analysis and design for a mean time to failure seems to be an unjustified extension of the use of methods of reliability analysis developed for inexpensive mass-produced items of relatively short service lives to the reliability assessment of expensive, large units. A method for the estimate of the expected time to the first failure is outlined and the implications of the use of this time in reliability analysis and design are discussed.Keywords
