An inspection and maintenance data storage and retrieval system features memory buttons each mounted in association with an equipment item, with each memory button having a read-write memory and an associated unique identifier. Inspection and maintenance data relating to the equipment item is stored in a remote central database. A memory button probe is used in conjunction with a portable computer to write data to and to read data from the memory buttons' read-write memories. The portable computer transfers data from the memory button probe to the central database at the point of inspection or maintenance, and vice versa. 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 items supported by the system.
