1. A method for aircraft maintenance, the method comprising:
loading, into computer memory, a plurality of unstructured aircraft component records originating from one or more different component status monitors, the plurality of unstructured aircraft component records describing observed maintenance conditions of a plurality of different aircraft components, wherein the plurality of unstructured aircraft component records do not follow a predefined schema in which information is organized into two or more distinct fields;
providing the plurality of unstructured aircraft component records from computer memory to a natural language processing (NLP) model configured to output a corresponding plurality of digital component, condition, and location (CCL) records for the plurality of different aircraft components;
independently computer aggregating CCL records for a plurality of different CCL types; and
computer analyzing the CCL records for a selected CCL type to determine a time-dependent failure distribution for the selected CCL type.
