This report investigates the concept of scheduling aircraft component replacements on the basis of time between overhaul TBO limits. The conditions under which the use of a TBO limit can be justified are examined. Statistical and reliability theories applicable to planned replacement programs are studied. Component failure characteristics assumed by classical reliability theory are compared with actual failure data for various types of aircraft components. Finally, recommendations are presented for developing and managing a component TBO program.
