1. A method comprising:

  • receiving, by a computing device comprising a processor, an anticipated usage input, a load input and a strength input associated with one of an aircraft and an aircraft component;

    calculating, by the computing device, a baseline reliability value based at least in part on the anticipated usage input, the load input and the strength input of the one of an aircraft and an aircraft component;

    receiving, by the computing device, usage data associated with use of the one of an aircraft and an aircraft component;

    generating, by the computing device, an updated reliability value based on at least some of the inputs used to calculate the baseline reliability value and the usage data;

    comparing measured data for a regime of use with data based on at least one user input;

    determining a category of uncertainty in the usage data based on the comparison;

    fitting a distribution to the usage data based on the category;

    determining, by the computing device, a lifetime for the one of an aircraft and an aircraft component based on the updated reliability value; and

    updating a usage monitor and reliability factor (UMRF) of the one of the aircraft and the aircraft component based on the determined lifetime; and

    retiring the one of the aircraft and the aircraft component after the UMRF indicates a retirement time.
