Abstract

An inspection and maintenance data storage and retrieval system features uniquely identified read/write memory buttons mounted in or on an equipment unit such as an aircraft, in association with specific components of the equipment unit. Technical information useful for inspection and maintenance of the components, plus historical inspection and maintenance information, is stored in a central database computer remote from the equipment unit. A memory button probe, used in conjunction with a portable computer, enables storage on the memory buttons of information relating to inspection and maintenance carried out on the corresponding equipment components, as well as technical information related to the components. The portable computer is connected to the central database computer, preferably through a wireless Internet connection, thus enabling downloading of technical information from the central database to the portable computer at the point of inspection or maintenance. Information relating to each inspection and maintenance task may be downloaded to the central database computer via the portable computer. The central database computer may be a network server providing authorized users with access to current maintenance and operational status information for the equipment units supported by the system.

Claims

1. A method for verifying physical access by an inspection agent to a selected component of an aircraft and for storing related in information on the selected aircraft component, said method comprising the steps of:

(a) providing a memory button comprising a read-write memory chip sealed inside an armoured container, said memory chip having stored therein a unique and unalterable identification number, and said armoured container comprising contact means electrically connected to the memory chip;

(b) associating the memory chip'"'"'s unique identification number with the selected aircraft component;

(c) permanently affixing the memory button to the selected aircraft component;

(d) providing a portable computing device having a read-write memory and a user interface whereby a user may enter user-defined data and commands into said read-write memory;

(e) providing a memory button probe in hard-wired electronic communication with the portable computing device, said memory button probe having contact means adapted for contacting engagement with the contact means of the memory button, so as to transfer data from the portable computing device to the memory button or from the memory button to the portable computing device;

(f) associating a unique inspector code with a specific inspection agent;

(g) gaining physical access to the memory button, while carrying both the portable computing device and the memory button probe;

(h) by means of the user interface, entering the unique inspector code into the memory of the portable computing device;

(i) bringing the contact means of the memory button probe into physical contact with the contact means of the memory button so as to record;

i.1 in the read-write memory of the memory chip, the unique inspector code, plus the date and time; and

i.2 in the memory of the portable computing device, the memory chip'"'"'s unique identification number, plus the time and date;

(j) performing a selected inspection or maintenance task on the aircraft component to which the memory button is affixed;

(k) by means of the user interface, entering task performance information into the portable computing device relating to the completed performance of the selected inspection or maintenance task;

(l) engaging the contact means of the memory button probe with the contact means of the memory button so as to electronically transmit a signal, corresponding to said task performance information, from the portable computing device to the memory button, and so as to store said task performance information on the memory button'"'"'s read-write memory chip;

(m) providing, at a location remote from the aircraft, a central computer having a database, said central computer being in electronic communication with the portable computing device; and

(n) transmitting a signal from the portable computing device to the central computer, so as to store said task performance information in said database;

wherein;

(o) the aircraft has no onboard means for reading information stored in the memory button; and

(p) steps (g), (h), (i), (j), (k), and (l) are performed by the specific inspection agent referred to in step (f);

and wherein the database of the central computer stores technical information relating to the selected aircraft component, and wherein the method comprises the additional step of transmitting a signal from the portable computing device to the central computer, instructing the central computer to transmit, from the database to the portable computing device via the second data transfer link, selected technical information relating to the selected aircraft component.

2. The method or claim 1 wherein the portable computing device is a laptop computer.

3. The method of claim 1 wherein the portable computing device is a personal digital assistant.

4. The method of claim 1 wherein the central computer is in electronic communication with the portable computing device by means of a wireless data transfer link.

5. The method of claim 4 wherein the wireless data transfer link is a wireless connection through a computer network.

6. The method of claim 4 wherein the wireless data transfer link is a connection through a telecommunications satellite system.

7. The method of claim 1, comprising the additional step of transferring said technical information from the portable computing device to the memory button by engaging the contact means of the memory button probe with the contact means of the memory button contacting engagement of the memory button probe with the memory button.

8. The method of claim 1 wherein the memory button stores technical information relating to the selected aircraft component, and wherein the method comprises the additional step of downloading selected technical information from the memory button, for use in association with the selected inspection or maintenance task, by engaging the contact means of the memory button probe with the contact means of the memory button.
