General[edit | edit source]

Maintenance is

Any act that either prevents the failure or malfunction of equipment or restores its operating capability.[1]
[a]ction necessary to retain or restore an item to a specified condition.[2]

Hardware[edit | edit source]

Maintenance is "the servicing of the machine in order to make it work in accordance with its original specifications and any changes to those specifications authorized for that machine. . . ."[3]

[T]he term 'maintenance' has a much broader temporal connotation [than 'repair']. The Senate Report on section 117 characterized 'maintenance' as including 'checking the proper functioning of [ ] components.' . . . Thus, maintenance, or 'servicing,' was meant to encompass monitoring systems for problems, not simply fixing a single, isolated malfunction."[4]
