Remotely performed maintenance of a transportation unit such as an aircraft is disclosed, wherein the maintenance is performed utilizing a networked environment. In one implementation, a first network, located within the mobile transportation unit, is accessed from a second network, located externally to the mobile transportation unit. Having remotely assessed the first network, communication with one or more assets of the mobile transportation unit, which are connected to the first network, is possible. Maintenance operations are then performed by exchanging data and commands with the assets of the mobile transportation unit.

A structure health monitoring (“SHM”) system according to the invention can be deployed in an onboard environment, such as an aircraft, to provide an ongoing damage assessment of structural components on the aircraft. The SHM system reduces or eliminates time consuming and costly manual inspections of aircraft. The SHM system can leverage known sensor technologies to collect sensor data indicative of the structural health of the monitored components. The sensor data is processed and baselined with sensor feature baselines and damage estimate baselines to provide an accurate final damage estimate for the monitored component. The final damage estimate can be further processed or formatted for compatibility with aircraft maintenance systems.

Aircraft maintenance and repair work is facilitated, especially for a commercial aircraft, by a diagnostic system and method, wherein an aircraft component or assembly of components is monitored by at least one sensor which produces and preferably also stores component status information. Respective status information signals are transmitted, preferably in a wireless manner, from a transmitter of the sensor to a receiver of a signal processing unit which provides status information on a display screen. The status information signals are preferably processed and evaluated with reference to rated maintenance and repair reference information to provide instructions as to what needs to be done where and when for a maintenance or repair. The sensor or sensors may operate during flight and the respective stored information is then processed and used on the ground.

A system includes a computer server for receiving an aircraft dataset; a database operably coupled to the computer server for storing the aircraft dataset into data fields; a web portal operably coupled to the computer server and the database for providing real-time access to consumers; and a maintenance analysis engine coupled to the computer server, the database, and the web portal to process the aircraft dataset into informational reports for an automatic delivery to the consumers, and optionally issuing a notification for retrieval thereof. The system employs a method of analyzing aircraft data for preventative maintenance, comprising: utilizing an aircraft dataset from at least one operational source; parsing the aircraft dataset into at least one data field; determining an acceptable range of values for the aircraft dataset within the at least one data field to define a threshold for the aircraft dataset; automatically activating a dynamic trigger to indicate a maintenance alert when the threshold is crossed; deriving a performance indication for the at least one operational source by determining one or more performance trends of the aircraft dataset; associating with the maintenance alert a notification having a status level indicative of a maintenance condition for the at least one operational source; combining the performance indication and the notification into an electronic report that forecasts need for preventative aircraft maintenance; and automatically delivering the electronic report to a predetermined location for retrieval by a consumer.
