6. The system of claim 1, wherein the portable communication device comprises a portable database component for storage of the service bulletin data related to the at least one aircraft or at least one part thereof.
7. The system of claim 6, wherein the service bulletin data stored in the portable database component of the portable communication device provides the user with guided interactive inspection of the at least one aircraft by viewing portions of the service bulletin data that are selectively searchable based on input by the user.
8. The system of claim 6, wherein the user input is stored in the portable database component and transferred from the portable communication device to the processing component for storage in the database component.
9. The system of claim 6, wherein the user input includes user answers to questions and one or more recorded results to the questions are stored in the portable database component and transferred to the processing component for storage in the database component.
10. A method for exchanging data over a network, the method comprising:
communicating with a user via a portable communication device over the network;
downloading an interactive software application to the portable communication device;
interacting with the user via the interactive software application;
receiving a request for service bulletin data related to the at least one aircraft from the user via the portable communication device;
accessing service bulletin data related to the at least one aircraft from a database component based on a registry number associated with the at least one aircraft passed with the request from the user; and
transferring service bulletin data related to the at least one aircraft from the database component to the portable communication device via the network for viewing by the user on the portable communication device.
11. The method of claim 10, wherein the method is performed by a server in communication with the portable communication device over the network.
12. The method of claim 10, wherein the portable communication device comprises at least one of a cell phone and personal digital assistant (PDA).
13. The method of claim 10, further comprising displaying the service bulletin data to the user via a display component of the portable communication device.
14. The method of claim 10, further comprising storing the service bulletin data in a portable database component of the portable communication device.
15. The method of claim 10, receiving input from the user including the registry number of the at least one aircraft.
16. The method of claim 10, further comprising providing the user with guided interactive inspection of the at least one aircraft by allowing the user to selectively view portions of the service bulletin data.
17. The method of claim 16, wherein the portions of the service bulletin data are selectively searchable based on input by the user.
18. The method of claim 17, further comprising recording the user input in the database component.
19. The method of claim 17, wherein the user input includes user answers to questions and one or more recorded results to the questions are recorded in the database component.
20. A system for facilitating transfer of data and information over a network, the system comprising:
means for communicating with a user via a portable communication device over the network;
means for downloading an interactive software application to the portable communication device;
means for interacting with the user via the interactive software application;
means for receiving a request for service bulletin data related to the at least one aircraft from the user via the portable communication device;
