1. A method for computerized aircraft fault isolation, the method comprising:
at a computing device, receiving a current maintenance-related pattern, the current maintenance-related pattern including a set of one or more digital maintenance messages reported during a flight of an aircraft;
comparing the current maintenance-related pattern to a digital maintenance records database, the digital maintenance records database including a plurality of historical maintenance-related patterns observed during prior aircraft flights, the plurality of historical maintenance-related patterns each having a same digital data format as the current maintenance-related pattern, and each historical maintenance-related pattern associated with an indication of one or more aircraft parts that, when replaced, resolved an underlying fault corresponding to the historical maintenance-related pattern;
based on an adaptive similarity threshold, computer-identifying a selected set of historical maintenance-related patterns from the digital maintenance records database as corresponding to the current maintenance-related pattern; and
computer-identifying a selected aircraft part associated with the selected set of historical maintenance-related patterns in the digital maintenance records database as a candidate for replacement on the aircraft to address the current maintenance-related pattern, wherein the selected aircraft part is computer-identified based at least in part on a number of prior documented replacements of the selected aircraft part in the digital maintenance records database, and a fault-resolution likelihood for the selected aircraft part.
