This application claims the benefit of U.S. Provisional Application No. 60/175,178, filed January 7, 2000, which is hereby incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION
This invention relates generally to customer services, and more specifically to methods and systems for accessing turbine engine aircraft components repair order information and services.
Manufacturers of aircraft engines normally provide repair and inspection services for engine and engine components. However, after an inspection of the engine has been completed, or engine component parts sent in for repair have been repaired, communicating the inspection results to engine owners, e.g. customers, has typically been a time consuming and potentially frustrating process for both the engine manufacturer and the customer. Currently communicating inspection results from incoming inspections of aircraft engines or component parts typically involves reporting the results in tabular form, and submitting the reports to customers via mail or facsimile. In addition, variations in the inspections of different facilities is a source of customer concern.
It would be desirable to provide incoming inspection reports to customers which include information in addition to known tabular reports. Since, customers often desire photographs of damaged components or parts found during the incoming inspections, it would be further desirable to have a systenvcapability that provides customers with photographs of damaged components or parts found during incoming inspections. It would be further desirable to provide quotes for repair services, linkage to new spare parts replenishment, and inspection standardization to reduce variations between repair facilities.

Server system 14 (shown in Figure 1) downloads 220 and displays 230 several options. Once the user selects 240 a specific option out of various hypertext links, the request is sent to server system 14. Selecting 240 a specific option is accomplished either by click of a mouse or by a voice command. The selected option is transmitted 260 to server system 14. Once server system 14 receives 270 a request, server system 14 accesses 280 databases and applications 18, 20, 22, 24, 26, and 28 (shown in Figure 1) and retrieves 290 pertinent information from databases (shown in Figure 1). The requested information is downloaded 292 and provided 300 to client system 14 (shown in Figure 1) from server 14. Server system 14 provides 300 the requested information to the user by either displaying 310 the information on the user's display or by printing 312 it to an attached or a remote printer. The user continues to search various databases for other information, updates 330 the database 20 by adding 334 folders or files, deleting 336 folders or files to database 20 with new or revised information, or exits 350 from system 10.
Updated information 354 is received 356 by server system 14 for storing 358 in appropriate databases. The user also updates 330 the database 20 by adding, deleting or modifying the information regarding a specific engine component(s). In another embodiment, client system 16, as well as server system 14, are protected from access by unauthorized individuals. As described, system 10 is an interactive searchable database 20 for all inspection & repair information and provides flexibility to users to stay current with up-to-date information. The system provides the ability for users to directly update, review and generate quotations based on current information and provide up to date information to customers for their review,
