Abstract

The system provides engine maintenance information automatically from fault code data received from an onboard engine performance monitoring computer. The maintenance information is provided by an HTML repair guide electronically called by the control system using the fault code as part of the page address in the HTML guide. The control system automatically ensures that all fault codes are responded to, i.e. that maintenance personnel carry out the appropriate maintenance actions in response to each and every fault code, with a view to improve quality assurance of maintenance. Maintenance actions of maintenance personnel are automatically recorded for the purposes of validating and/or generating warranty claim applications. The system also has a warranty claim report generator for processing aircraft maintenance action log data. The generator has a warranty action discriminator for reading the action log data and outputting data representing possible warranty covered actions, and a warranty action validator receiving the possible warranty covered actions data and engine performance data for outputting data representing warranty claim actions. The warranty claim actions data are processed to produce warranty claim report output data.
