sponsible for performing that particular maintenance function. The symbol "%%" which applies to
organizational maintenance indicates the particular maintenance function may be performed provided
it is specifically authorized by the direct support maintenance officer. Use of the symbol will apply
only to replacement of major assemblies and time-consuming operations which are within the capabil-
ities of organization, but over which control by the commodity commands is considered essential. In no
case will the direct support maintenance officer require the accomplishment of a "%%" maintenance
function by an organization or unit, and in no case will a "%%" function authorize stockage of parts
at organizational level.

bility, becomes the responsibility of the next higher maintenance level.
