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.
